These cases arise + when (on a little-endian machine) a non-prototyped function has a + parameter declared to be of type `short' or `char'. In such cases, + TREE_TYPE (decl) will be `short' or `char', DECL_ARG_TYPE (decl) will + be `int', and DECL_INCOMING_RTL will point to the lowest-order byte of the + passed `int' value. If the debugger then uses that address to fetch + a `short' or a `char' (on a little-endian machine) the result will be + the correct data, so we allow for such exceptional cases below. + + Note that our goal here is to describe the place where the given formal + parameter lives during most of the function's activation (i.e. between + the end of the prologue and the start of the epilogue).

This event can then be "caught" or "trapped" by the + callers of this function. This potentially allows program flow to + be transferred to any arbitrary code associated with a function call + several levels up the stack. + + The intended use for this mechanism is for signaling "exceptional + events" in an out-of-band fashion, hence its name. The C++ language + (and many other OO-styled or functional languages) practically + requires such a mechanism, as otherwise it becomes very difficult + or even impossible to signal failure conditions in complex + situations. The traditional C++ example is when an error occurs in + the process of constructing an object; without such a mechanism, it + is impossible to signal that the error occurs without adding global + state variables and error checks around every object construction. + + The act of causing this event to occur is referred to as "throwing + an exception". (Alternate terms include "raising an exception" or + "signaling an exception".) The term "throw" is used because control + is returned to the callers of the function that is signaling the + exception, and thus there is the concept of "throwing" the + exception up the call stack. + + There are two major codegen options for exception handling. The + flag -fsjlj-exceptions can be used to select the setjmp/longjmp + approach, which is the default. -fno-sjlj-exceptions can be used to + get the PC range table approach. While this is a compile time + flag, an entire application must be compiled with the same codegen + option. The first is a PC range table approach, the second is a + setjmp/longjmp based scheme. We will first discuss the PC range + table approach, after that, we will discuss the setjmp/longjmp + based approach. + + It is appropriate to speak of the "context of a throw". This + context refers to the address where the exception is thrown from, + and is used to determine which exception region will handle the + exception. + + Regions of code within a function can be marked such that if it + contains the context of a throw, control will be passed to a + designated "exception handler". These areas are known as "exception + regions". Exception regions cannot overlap, but they can be nested + to any arbitrary depth. Also, exception regions cannot cross + function boundaries. + + Exception handlers can either be specified by the user (which we + will call a "user-defined handler") or generated by the compiler + (which we will designate as a "cleanup"). Cleanups are used to + perform tasks such as destruction of objects allocated on the + stack. + + In the current implementation, cleanups are handled by allocating an + exception region for the area that the cleanup is designated for, + and the handler for the region performs the cleanup and then + rethrows the exception to the outer exception region. From the + standpoint of the current implementation, there is little + distinction made between a cleanup and a user-defined handler, and + the phrase "exception handler" can be used to refer to either one + equally well. (The section "Future Directions" below discusses how + this will change). + + Each object file that is compiled with exception handling contains + a static array of exception handlers named __EXCEPTION_TABLE__. + Each entry contains the starting and ending addresses of the + exception region, and the address of the handler designated for + that region. + + If the target does not use the DWARF 2 frame unwind information, at + program startup each object file invokes a function named + __register_exceptions with the address of its local + __EXCEPTION_TABLE__. __register_exceptions is defined in libgcc2.c, and + is responsible for recording all of the exception regions into one list + (which is kept in a static variable named exception_table_list). + + On targets that support crtstuff.c, the unwind information + is stored in a section named .eh_frame and the information for the + entire shared object or program is registered with a call to + __register_frame_info. On other targets, the information for each + translation unit is registered from the file generated by collect2. + __register_frame_info is defined in frame.c, and is responsible for + recording all of the unwind regions into one list (which is kept in a + static variable named unwind_table_list). + + The function __throw is actually responsible for doing the + throw. On machines that have unwind info support, __throw is generated + by code in libgcc2.c, otherwise __throw is generated on a + per-object-file basis for each source file compiled with + -fexceptions by the the C++ frontend. Before __throw is invoked, + the current context of the throw needs to be placed in the global + variable __eh_pc. + + __throw attempts to find the appropriate exception handler for the + PC value stored in __eh_pc by calling __find_first_exception_table_match + (which is defined in libgcc2.c). If __find_first_exception_table_match + finds a relevant handler, __throw transfers control directly to it. + + If a handler for the context being thrown from can't be found, __throw + walks (see Walking the stack below) the stack up the dynamic call chain to + continue searching for an appropriate exception handler based upon the + caller of the function it last sought a exception handler for. It stops + then either an exception handler is found, or when the top of the + call chain is reached. + + If no handler is found, an external library function named + __terminate is called. If a handler is found, then we restart + our search for a handler at the end of the call chain, and repeat + the search process, but instead of just walking up the call chain, + we unwind the call chain as we walk up it. + + Internal implementation details: + + To associate a user-defined handler with a block of statements, the + function expand_start_try_stmts is used to mark the start of the + block of statements with which the handler is to be associated + (which is known as a "try block"). All statements that appear + afterwards will be associated with the try block. + + A call to expand_start_all_catch marks the end of the try block, + and also marks the start of the "catch block" (the user-defined + handler) associated with the try block. + + This user-defined handler will be invoked for *every* exception + thrown with the context of the try block. It is up to the handler + to decide whether or not it wishes to handle any given exception, + as there is currently no mechanism in this implementation for doing + this. (There are plans for conditionally processing an exception + based on its "type", which will provide a language-independent + mechanism). + + If the handler chooses not to process the exception (perhaps by + looking at an "exception type" or some other additional data + supplied with the exception), it can fall through to the end of the + handler. expand_end_all_catch and expand_leftover_cleanups + add additional code to the end of each handler to take care of + rethrowing to the outer exception handler. + + The handler also has the option to continue with "normal flow of + code", or in other words to resume executing at the statement + immediately after the end of the exception region. The variable + caught_return_label_stack contains a stack of labels, and jumping + to the topmost entry's label via expand_goto will resume normal + flow to the statement immediately after the end of the exception + region. If the handler falls through to the end, the exception will + be rethrown to the outer exception region. + + The instructions for the catch block are kept as a separate + sequence, and will be emitted at the end of the function along with + the handlers specified via expand_eh_region_end. The end of the + catch block is marked with expand_end_all_catch. + + Any data associated with the exception must currently be handled by + some external mechanism maintained in the frontend. For example, + the C++ exception mechanism passes an arbitrary value along with + the exception, and this is handled in the C++ frontend by using a + global variable to hold the value. (This will be changing in the + future.) + + The mechanism in C++ for handling data associated with the + exception is clearly not thread-safe. For a thread-based + environment, another mechanism must be used (possibly using a + per-thread allocation mechanism if the size of the area that needs + to be allocated isn't known at compile time.) + + Internally-generated exception regions (cleanups) are marked by + calling expand_eh_region_start to mark the start of the region, + and expand_eh_region_end (handler) is used to both designate the + end of the region and to associate a specified handler/cleanup with + the region. The rtl code in HANDLER will be invoked whenever an + exception occurs in the region between the calls to + expand_eh_region_start and expand_eh_region_end. After HANDLER is + executed, additional code is emitted to handle rethrowing the + exception to the outer exception handler. The code for HANDLER will + be emitted at the end of the function. + + TARGET_EXPRs can also be used to designate exception regions. A + TARGET_EXPR gives an unwind-protect style interface commonly used + in functional languages such as LISP. The associated expression is + evaluated, and whether or not it (or any of the functions that it + calls) throws an exception, the protect expression is always + invoked. This implementation takes care of the details of + associating an exception table entry with the expression and + generating the necessary code (it actually emits the protect + expression twice, once for normal flow and once for the exception + case). As for the other handlers, the code for the exception case + will be emitted at the end of the function. + + Cleanups can also be specified by using add_partial_entry (handler) + and end_protect_partials. add_partial_entry creates the start of + a new exception region; HANDLER will be invoked if an exception is + thrown with the context of the region between the calls to + add_partial_entry and end_protect_partials. end_protect_partials is + used to mark the end of these regions. add_partial_entry can be + called as many times as needed before calling end_protect_partials. + However, end_protect_partials should only be invoked once for each + group of calls to add_partial_entry as the entries are queued + and all of the outstanding entries are processed simultaneously + when end_protect_partials is invoked. Similarly to the other + handlers, the code for HANDLER will be emitted at the end of the + function. + + The generated RTL for an exception region includes + NOTE_INSN_EH_REGION_BEG and NOTE_INSN_EH_REGION_END notes that mark + the start and end of the exception region. A unique label is also + generated at the start of the exception region, which is available + by looking at the ehstack variable. The topmost entry corresponds + to the current region. + + In the current implementation, an exception can only be thrown from + a function call (since the mechanism used to actually throw an + exception involves calling __throw). If an exception region is + created but no function calls occur within that region, the region + can be safely optimized away (along with its exception handlers) + since no exceptions can ever be caught in that region. This + optimization is performed unless -fasynchronous-exceptions is + given. If the user wishes to throw from a signal handler, or other + asynchronous place, -fasynchronous-exceptions should be used when + compiling for maximally correct code, at the cost of additional + exception regions. Using -fasynchronous-exceptions only produces + code that is reasonably safe in such situations, but a correct + program cannot rely upon this working. It can be used in failsafe + code, where trying to continue on, and proceeding with potentially + incorrect results is better than halting the program. + + + Walking the stack: + + The stack is walked by starting with a pointer to the current + frame, and finding the pointer to the callers frame. The unwind info + tells __throw how to find it. + + Unwinding the stack: + + When we use the term unwinding the stack, we mean undoing the + effects of the function prologue in a controlled fashion so that we + still have the flow of control. Otherwise, we could just return + (jump to the normal end of function epilogue). + + This is done in __throw in libgcc2.c when we know that a handler exists + in a frame higher up the call stack than its immediate caller. + + To unwind, we find the unwind data associated with the frame, if any. + If we don't find any, we call the library routine __terminate. If we do + find it, we use the information to copy the saved register values from + that frame into the register save area in the frame for __throw, return + into a stub which updates the stack pointer, and jump to the handler. + The normal function epilogue for __throw handles restoring the saved + values into registers. + + When unwinding, we use this method if we know it will + work (if DWARF2_UNWIND_INFO is defined). Otherwise, we know that + an inline unwinder will have been emitted for any function that + __unwind_function cannot unwind. The inline unwinder appears as a + normal exception handler for the entire function, for any function + that we know cannot be unwound by __unwind_function. We inform the + compiler of whether a function can be unwound with + __unwind_function by having DOESNT_NEED_UNWINDER evaluate to true + when the unwinder isn't needed. __unwind_function is used as an + action of last resort. If no other method can be used for + unwinding, __unwind_function is used. If it cannot unwind, it + should call __terminate. + + By default, if the target-specific backend doesn't supply a definition + for __unwind_function and doesn't support DWARF2_UNWIND_INFO, inlined + unwinders will be used instead. The main tradeoff here is in text space + utilization. Obviously, if inline unwinders have to be generated + repeatedly, this uses much more space than if a single routine is used. + + However, it is simply not possible on some platforms to write a + generalized routine for doing stack unwinding without having some + form of additional data associated with each function. The current + implementation can encode this data in the form of additional + machine instructions or as static data in tabular form. The later + is called the unwind data. + + The backend macro DOESNT_NEED_UNWINDER is used to conditionalize whether + or not per-function unwinders are needed. If DOESNT_NEED_UNWINDER is + defined and has a non-zero value, a per-function unwinder is not emitted + for the current function. If the static unwind data is supported, then + a per-function unwinder is not emitted. + + On some platforms it is possible that neither __unwind_function + nor inlined unwinders are available. For these platforms it is not + possible to throw through a function call, and abort will be + invoked instead of performing the throw. + + The reason the unwind data may be needed is that on some platforms + the order and types of data stored on the stack can vary depending + on the type of function, its arguments and returned values, and the + compilation options used (optimization versus non-optimization, + -fomit-frame-pointer, processor variations, etc). + + Unfortunately, this also means that throwing through functions that + aren't compiled with exception handling support will still not be + possible on some platforms. This problem is currently being + investigated, but no solutions have been found that do not imply + some unacceptable performance penalties. + + Future directions: + + Currently __throw makes no differentiation between cleanups and + user-defined exception regions. While this makes the implementation + simple, it also implies that it is impossible to determine if a + user-defined exception handler exists for a given exception without + completely unwinding the stack in the process. This is undesirable + from the standpoint of debugging, as ideally it would be possible + to trap unhandled exceptions in the debugger before the process of + unwinding has even started. + + This problem can be solved by marking user-defined handlers in a + special way (probably by adding additional bits to exception_table_list). + A two-pass scheme could then be used by __throw to iterate + through the table. The first pass would search for a relevant + user-defined handler for the current context of the throw, and if + one is found, the second pass would then invoke all needed cleanups + before jumping to the user-defined handler. + + Many languages (including C++ and Ada) make execution of a + user-defined handler conditional on the "type" of the exception + thrown. (The type of the exception is actually the type of the data + that is thrown with the exception.) It will thus be necessary for + __throw to be able to determine if a given user-defined + exception handler will actually be executed, given the type of + exception. + + One scheme is to add additional information to exception_table_list + as to the types of exceptions accepted by each handler. __throw + can do the type comparisons and then determine if the handler is + actually going to be executed. + + There is currently no significant level of debugging support + available, other than to place a breakpoint on __throw. While + this is sufficient in most cases, it would be helpful to be able to + know where a given exception was going to be thrown to before it is + actually thrown, and to be able to choose between stopping before + every exception region (including cleanups), or just user-defined + exception regions. This should be possible to do in the two-pass + scheme by adding additional labels to __throw for appropriate + breakpoints, and additional debugger commands could be added to + query various state variables to determine what actions are to be + performed next. + + Another major problem that is being worked on is the issue with stack + unwinding on various platforms. Currently the only platforms that have + support for the generation of a generic unwinder are the SPARC and MIPS. + All other ports require per-function unwinders, which produce large + amounts of code bloat. + + For setjmp/longjmp based exception handling, some of the details + are as above, but there are some additional details. This section + discusses the details. + + We don't use NOTE_INSN_EH_REGION_{BEG,END} pairs. We don't + optimize EH regions yet. We don't have to worry about machine + specific issues with unwinding the stack, as we rely upon longjmp + for all the machine specific details. There is no variable context + of a throw, just the one implied by the dynamic handler stack + pointed to by the dynamic handler chain. There is no exception + table, and no calls to __register_exceptions. __sjthrow is used + instead of __throw, and it works by using the dynamic handler + chain, and longjmp. -fasynchronous-exceptions has no effect, as + the elimination of trivial exception regions is not yet performed. + + A frontend can set protect_cleanup_actions_with_terminate when all + the cleanup actions should be protected with an EH region that + calls terminate when an unhandled exception is throw.

This macro is called within an initializer of an + array of structures. The first field in the structure is the name + of a predicate and the second field is an array of rtl codes. For + each predicate, list all rtl codes that can be in expressions + matched by the predicate. The list should have a trailing comma. + Here is an example of two entries in the list for a typical RISC + machine: + + #define PREDICATE_CODES \ + {"gen_reg_rtx_operand", {SUBREG, REG}}, \ + {"reg_or_short_cint_operand", {SUBREG, REG, CONST_INT}}, + + Defining this macro does not affect the generated code (however, + incorrect definitions that omit an rtl code that may be matched by + the predicate can cause the compiler to malfunction). Instead, it + allows the table built by `genrecog' to be more compact and + efficient, thus speeding up the compiler. The most important + predicates to include in the list specified by this macro are + thoses used in the most insn patterns. + +`CASE_VECTOR_MODE' + An alias for a machine mode name. This is the machine mode that + elements of a jump-table should have. + +`CASE_VECTOR_PC_RELATIVE' + Define this macro if jump-tables should contain relative addresses. + +`CASE_DROPS_THROUGH' + Define this if control falls through a `case' insn when the index + value is out of range. This means the specified default-label is + actually ignored by the `case' insn proper. + +`CASE_VALUES_THRESHOLD' + Define this to be the smallest number of different values for + which it is best to use a jump-table instead of a tree of + conditional branches. The default is four for machines with a + `casesi' instruction and five otherwise. This is best for most + machines. + +`WORD_REGISTER_OPERATIONS' + Define this macro if operations between registers with integral + mode smaller than a word are always performed on the entire + register. Most RISC machines have this property and most CISC + machines do not. + +`LOAD_EXTEND_OP (MODE)' + Define this macro to be a C expression indicating when insns that + read memory in MODE, an integral mode narrower than a word, set the + bits outside of MODE to be either the sign-extension or the + zero-extension of the data read. Return `SIGN_EXTEND' for values + of MODE for which the insn sign-extends, `ZERO_EXTEND' for which + it zero-extends, and `NIL' for other modes. + + This macro is not called with MODE non-integral or with a width + greater than or equal to `BITS_PER_WORD', so you may return any + value in this case. Do not define this macro if it would always + return `NIL'. On machines where this macro is defined, you will + normally define it as the constant `SIGN_EXTEND' or `ZERO_EXTEND'. + +`SHORT_IMMEDIATES_SIGN_EXTEND' + Define this macro if loading short immediate values into registers + sign extends. + +`IMPLICIT_FIX_EXPR' + An alias for a tree code that should be used by default for + conversion of floating point values to fixed point. Normally, + `FIX_ROUND_EXPR' is used. + +`FIXUNS_TRUNC_LIKE_FIX_TRUNC' + Define this macro if the same instructions that convert a floating + point number to a signed fixed point number also convert validly + to an unsigned one. + +`EASY_DIV_EXPR' + An alias for a tree code that is the easiest kind of division to + compile code for in the general case. It may be `TRUNC_DIV_EXPR', + `FLOOR_DIV_EXPR', `CEIL_DIV_EXPR' or `ROUND_DIV_EXPR'. These four + division operators differ in how they round the result to an + integer. `EASY_DIV_EXPR' is used when it is permissible to use + any of those kinds of division and the choice should be made on + the basis of efficiency. + +`MOVE_MAX' + The maximum number of bytes that a single instruction can move + quickly between memory and registers or between two memory + locations. + +`MAX_MOVE_MAX' + The maximum number of bytes that a single instruction can move + quickly between memory and registers or between two memory + locations. If this is undefined, the default is `MOVE_MAX'. + Otherwise, it is the constant value that is the largest value that + `MOVE_MAX' can have at run-time. + +`SHIFT_COUNT_TRUNCATED' + A C expression that is nonzero if on this machine the number of + bits actually used for the count of a shift operation is equal to + the number of bits needed to represent the size of the object + being shifted. When this macro is non-zero, the compiler will + assume that it is safe to omit a sign-extend, zero-extend, and + certain bitwise `and' instructions that truncates the count of a + shift operation. On machines that have instructions that act on + bitfields at variable positions, which may include `bit test' + instructions, a nonzero `SHIFT_COUNT_TRUNCATED' also enables + deletion of truncations of the values that serve as arguments to + bitfield instructions. + + If both types of instructions truncate the count (for shifts) and + position (for bitfield operations), or if no variable-position + bitfield instructions exist, you should define this macro. + + However, on some machines, such as the 80386 and the 680x0, + truncation only applies to shift operations and not the (real or + pretended) bitfield operations. Define `SHIFT_COUNT_TRUNCATED' to + be zero on such machines. Instead, add patterns to the `md' file + that include the implied truncation of the shift instructions. + + You need not define this macro if it would always have the value + of zero. + +`TRULY_NOOP_TRUNCATION (OUTPREC, INPREC)' + A C expression which is nonzero if on this machine it is safe to + "convert" an integer of INPREC bits to one of OUTPREC bits (where + OUTPREC is smaller than INPREC) by merely operating on it as if it + had only OUTPREC bits. + + On many machines, this expression can be 1. + + When `TRULY_NOOP_TRUNCATION' returns 1 for a pair of sizes for + modes for which `MODES_TIEABLE_P' is 0, suboptimal code can result. + If this is the case, making `TRULY_NOOP_TRUNCATION' return 0 in + such cases may improve things. + +`STORE_FLAG_VALUE' + A C expression describing the value returned by a comparison + operator with an integral mode and stored by a store-flag + instruction (`sCOND') when the condition is true. This + description must apply to *all* the `sCOND' patterns and all the + comparison operators whose results have a `MODE_INT' mode. + + A value of 1 or -1 means that the instruction implementing the + comparison operator returns exactly 1 or -1 when the comparison is + true and 0 when the comparison is false. Otherwise, the value + indicates which bits of the result are guaranteed to be 1 when the + comparison is true. This value is interpreted in the mode of the + comparison operation, which is given by the mode of the first + operand in the `sCOND' pattern. Either the low bit or the sign + bit of `STORE_FLAG_VALUE' be on. Presently, only those bits are + used by the compiler. + + If `STORE_FLAG_VALUE' is neither 1 or -1, the compiler will + generate code that depends only on the specified bits. It can also + replace comparison operators with equivalent operations if they + cause the required bits to be set, even if the remaining bits are + undefined. For example, on a machine whose comparison operators + return an `SImode' value and where `STORE_FLAG_VALUE' is defined as + `0x80000000', saying that just the sign bit is relevant, the + expression + + (ne:SI (and:SI X (const_int POWER-OF-2)) (const_int 0)) + + can be converted to + + (ashift:SI X (const_int N)) + + where N is the appropriate shift count to move the bit being + tested into the sign bit. + + There is no way to describe a machine that always sets the + low-order bit for a true value, but does not guarantee the value + of any other bits, but we do not know of any machine that has such + an instruction. If you are trying to port GNU CC to such a + machine, include an instruction to perform a logical-and of the + result with 1 in the pattern for the comparison operators and let + us know (*note How to Report Bugs: Bug Reporting.). + + Often, a machine will have multiple instructions that obtain a + value from a comparison (or the condition codes). Here are rules + to guide the choice of value for `STORE_FLAG_VALUE', and hence the + instructions to be used: + + * Use the shortest sequence that yields a valid definition for + `STORE_FLAG_VALUE'. It is more efficient for the compiler to + "normalize" the value (convert it to, e.g., 1 or 0) than for + the comparison operators to do so because there may be + opportunities to combine the normalization with other + operations. + + * For equal-length sequences, use a value of 1 or -1, with -1 + being slightly preferred on machines with expensive jumps and + 1 preferred on other machines. + + * As a second choice, choose a value of `0x80000001' if + instructions exist that set both the sign and low-order bits + but do not define the others. + + * Otherwise, use a value of `0x80000000'. + + Many machines can produce both the value chosen for + `STORE_FLAG_VALUE' and its negation in the same number of + instructions. On those machines, you should also define a pattern + for those cases, e.g., one matching + + (set A (neg:M (ne:M B C))) + + Some machines can also perform `and' or `plus' operations on + condition code values with less instructions than the corresponding + `sCOND' insn followed by `and' or `plus'. On those machines, + define the appropriate patterns. Use the names `incscc' and + `decscc', respectively, for the patterns which perform `plus' or + `minus' operations on condition code values. See `rs6000.md' for + some examples. The GNU Superoptizer can be used to find such + instruction sequences on other machines. + + You need not define `STORE_FLAG_VALUE' if the machine has no + store-flag instructions. + +`FLOAT_STORE_FLAG_VALUE' + A C expression that gives a non-zero floating point value that is + returned when comparison operators with floating-point results are + true. Define this macro on machine that have comparison + operations that return floating-point values. If there are no + such operations, do not define this macro. + +`Pmode' + An alias for the machine mode for pointers. On most machines, + define this to be the integer mode corresponding to the width of a + hardware pointer; `SImode' on 32-bit machine or `DImode' on 64-bit + machines. On some machines you must define this to be one of the + partial integer modes, such as `PSImode'. + + The width of `Pmode' must be at least as large as the value of + `POINTER_SIZE'. If it is not equal, you must define the macro + `POINTERS_EXTEND_UNSIGNED' to specify how pointers are extended to + `Pmode'. + +`FUNCTION_MODE' + An alias for the machine mode used for memory references to + functions being called, in `call' RTL expressions. On most + machines this should be `QImode'. + +`INTEGRATE_THRESHOLD (DECL)' + A C expression for the maximum number of instructions above which + the function DECL should not be inlined. DECL is a + `FUNCTION_DECL' node. + + The default definition of this macro is 64 plus 8 times the number + of arguments that the function accepts. Some people think a larger + threshold should be used on RISC machines. + +`SCCS_DIRECTIVE' + Define this if the preprocessor should ignore `#sccs' directives + and print no error message. + +`NO_IMPLICIT_EXTERN_C' + Define this macro if the system header files support C++ as well + as C. This macro inhibits the usual method of using system header + files in C++, which is to pretend that the file's contents are + enclosed in `extern "C" {...}'. + +`HANDLE_PRAGMA (STREAM, NODE)' + Define this macro if you want to implement any pragmas. If + defined, it is a C expression whose value is 1 if the pragma was + handled by the function. The argument STREAM is the stdio input + stream from which the source text can be read. NODE is the tree + node for the identifier after the `#pragma'. + + It is generally a bad idea to implement new uses of `#pragma'. The + only reason to define this macro is for compatibility with other + compilers that do support `#pragma' for the sake of any user + programs which already use it. + +`VALID_MACHINE_DECL_ATTRIBUTE (DECL, ATTRIBUTES, IDENTIFIER, ARGS)' + If defined, a C expression whose value is nonzero if IDENTIFIER + with arguments ARGS is a valid machine specific attribute for DECL. + The attributes in ATTRIBUTES have previously been assigned to DECL. + +`VALID_MACHINE_TYPE_ATTRIBUTE (TYPE, ATTRIBUTES, IDENTIFIER, ARGS)' + If defined, a C expression whose value is nonzero if IDENTIFIER + with arguments ARGS is a valid machine specific attribute for TYPE. + The attributes in ATTRIBUTES have previously been assigned to TYPE. + +`COMP_TYPE_ATTRIBUTES (TYPE1, TYPE2)' + If defined, a C expression whose value is zero if the attributes on + TYPE1 and TYPE2 are incompatible, one if they are compatible, and + two if they are nearly compatible (which causes a warning to be + generated). + +`SET_DEFAULT_TYPE_ATTRIBUTES (TYPE)' + If defined, a C statement that assigns default attributes to newly + defined TYPE. + +`DOLLARS_IN_IDENTIFIERS' + Define this macro to control use of the character `$' in identifier + names. 0 means `$' is not allowed by default; 1 means it is + allowed. 1 is the default; there is no need to define this macro + in that case. This macro controls the compiler proper; it does + not affect the preprocessor. + +`NO_DOLLAR_IN_LABEL' + Define this macro if the assembler does not accept the character + `$' in label names. By default constructors and destructors in + G++ have `$' in the identifiers. If this macro is defined, `.' is + used instead. + +`NO_DOT_IN_LABEL' + Define this macro if the assembler does not accept the character + `.' in label names. By default constructors and destructors in G++ + have names that use `.'. If this macro is defined, these names + are rewritten to avoid `.'. + +`DEFAULT_MAIN_RETURN' + Define this macro if the target system expects every program's + `main' function to return a standard "success" value by default + (if no other value is explicitly returned). + + The definition should be a C statement (sans semicolon) to + generate the appropriate rtl instructions. It is used only when + compiling the end of `main'. + +`HAVE_ATEXIT' + Define this if the target system supports the function `atexit' + from the ANSI C standard. If this is not defined, and + `INIT_SECTION_ASM_OP' is not defined, a default `exit' function + will be provided to support C++. + +`EXIT_BODY' + Define this if your `exit' function needs to do something besides + calling an external function `_cleanup' before terminating with + `_exit'. The `EXIT_BODY' macro is only needed if neither + `HAVE_ATEXIT' nor `INIT_SECTION_ASM_OP' are defined. + +`INSN_SETS_ARE_DELAYED (INSN)' + Define this macro as a C expression that is nonzero if it is safe + for the delay slot scheduler to place instructions in the delay + slot of INSN, even if they appear to use a resource set or + clobbered in INSN. INSN is always a `jump_insn' or an `insn'; GNU + CC knows that every `call_insn' has this behavior. On machines + where some `insn' or `jump_insn' is really a function call and + hence has this behavior, you should define this macro. + + You need not define this macro if it would always return zero. + +`INSN_REFERENCES_ARE_DELAYED (INSN)' + Define this macro as a C expression that is nonzero if it is safe + for the delay slot scheduler to place instructions in the delay + slot of INSN, even if they appear to set or clobber a resource + referenced in INSN. INSN is always a `jump_insn' or an `insn'. + On machines where some `insn' or `jump_insn' is really a function + call and its operands are registers whose use is actually in the + subroutine it calls, you should define this macro. Doing so + allows the delay slot scheduler to move instructions which copy + arguments into the argument registers into the delay slot of INSN. + + You need not define this macro if it would always return zero. + +`MACHINE_DEPENDENT_REORG (INSN)' + In rare cases, correct code generation requires extra machine + dependent processing between the second jump optimization pass and + delayed branch scheduling. On those machines, define this macro + as a C statement to act on the code starting at INSN. + +`MULTIPLE_SYMBOL_SPACES' + Define this macro if in some cases global symbols from one + translation unit may not be bound to undefined symbols in another + translation unit without user intervention. For instance, under + Microsoft Windows symbols must be explicitly imported from shared + libraries (DLLs). + +`GIV_SORT_CRITERION (GIV1, GIV2)' + In some cases, the strength reduction optimization pass can + produce better code if this is defined. This macro controls the + order that induction variables are combined. This macro is + particularly useful if the target has limited addressing modes. + For instance, the SH target has only positive offsets in + addresses. Thus sorting to put the smallest address first allows + the most combinations to be found. + + +File: gcc.info, Node: Config, Next: Fragments, Prev: Target Macros, Up: Top + +The Configuration File +********************** + + The configuration file `xm-MACHINE.h' contains macro definitions +that describe the machine and system on which the compiler is running, +unlike the definitions in `MACHINE.h', which describe the machine for +which the compiler is producing output. Most of the values in +`xm-MACHINE.h' are actually the same on all machines that GNU CC runs +on, so large parts of all configuration files are identical. But there +are some macros that vary: + +`USG' + Define this macro if the host system is System V. + +`VMS' + Define this macro if the host system is VMS. + +`FATAL_EXIT_CODE' + A C expression for the status code to be returned when the compiler + exits after serious errors. + +`SUCCESS_EXIT_CODE' + A C expression for the status code to be returned when the compiler + exits without serious errors. + +`HOST_WORDS_BIG_ENDIAN' + Defined if the host machine stores words of multi-word values in + big-endian order. (GNU CC does not depend on the host byte + ordering within a word.) + +`HOST_FLOAT_WORDS_BIG_ENDIAN' + Define this macro to be 1 if the host machine stores `DFmode', + `XFmode' or `TFmode' floating point numbers in memory with the + word containing the sign bit at the lowest address; otherwise, + define it to be zero. + + This macro need not be defined if the ordering is the same as for + multi-word integers. + +`HOST_FLOAT_FORMAT' + A numeric code distinguishing the floating point format for the + host machine. See `TARGET_FLOAT_FORMAT' in *Note Storage Layout:: + for the alternatives and default. + +`HOST_BITS_PER_CHAR' + A C expression for the number of bits in `char' on the host + machine. + +`HOST_BITS_PER_SHORT' + A C expression for the number of bits in `short' on the host + machine. + +`HOST_BITS_PER_INT' + A C expression for the number of bits in `int' on the host machine. + +`HOST_BITS_PER_LONG' + A C expression for the number of bits in `long' on the host + machine. + +`ONLY_INT_FIELDS' + Define this macro to indicate that the host compiler only supports + `int' bit fields, rather than other integral types, including + `enum', as do most C compilers. + +`OBSTACK_CHUNK_SIZE' + A C expression for the size of ordinary obstack chunks. If you + don't define this, a usually-reasonable default is used. + +`OBSTACK_CHUNK_ALLOC' + The function used to allocate obstack chunks. If you don't define + this, `xmalloc' is used. + +`OBSTACK_CHUNK_FREE' + The function used to free obstack chunks. If you don't define + this, `free' is used. + +`USE_C_ALLOCA' + Define this macro to indicate that the compiler is running with the + `alloca' implemented in C. This version of `alloca' can be found + in the file `alloca.c'; to use it, you must also alter the + `Makefile' variable `ALLOCA'. (This is done automatically for the + systems on which we know it is needed.) + + If you do define this macro, you should probably do it as follows: + + #ifndef __GNUC__ + #define USE_C_ALLOCA + #else + #define alloca __builtin_alloca + #endif + + so that when the compiler is compiled with GNU CC it uses the more + efficient built-in `alloca' function. + +`FUNCTION_CONVERSION_BUG' + Define this macro to indicate that the host compiler does not + properly handle converting a function value to a + pointer-to-function when it is used in an expression. + +`MULTIBYTE_CHARS' + Define this macro to enable support for multibyte characters in the + input to GNU CC. This requires that the host system support the + ANSI C library functions for converting multibyte characters to + wide characters. + +`POSIX' + Define this if your system is POSIX.1 compliant. + +`NO_SYS_SIGLIST' + Define this if your system *does not* provide the variable + `sys_siglist'. + + Some systems do provide this variable, but with a different name + such as `_sys_siglist'. On these systems, you can define + `sys_siglist' as a macro which expands into the name actually + provided. + + Autoconf normally defines `SYS_SIGLIST_DECLARED' when it finds a + declaration of `sys_siglist' in the system header files. However, + when you define `sys_siglist' to a different name autoconf will + not automatically define `SYS_SIGLIST_DECLARED'. Therefore, if + you define `sys_siglist', you should also define + `SYS_SIGLIST_DECLARED'. + +`USE_PROTOTYPES' + Define this to be 1 if you know that the host compiler supports + prototypes, even if it doesn't define __STDC__, or define it to be + 0 if you do not want any prototypes used in compiling GNU CC. If + `USE_PROTOTYPES' is not defined, it will be determined + automatically whether your compiler supports prototypes by + checking if `__STDC__' is defined. + +`NO_MD_PROTOTYPES' + Define this if you wish suppression of prototypes generated from + the machine description file, but to use other prototypes within + GNU CC. If `USE_PROTOTYPES' is defined to be 0, or the host + compiler does not support prototypes, this macro has no effect. + +`MD_CALL_PROTOTYPES' + Define this if you wish to generate prototypes for the `gen_call' + or `gen_call_value' functions generated from the machine + description file. If `USE_PROTOTYPES' is defined to be 0, or the + host compiler does not support prototypes, or `NO_MD_PROTOTYPES' + is defined, this macro has no effect. As soon as all of the + machine descriptions are modified to have the appropriate number + of arguments, this macro will be removed. + +`NO_STAB_H' + Define this if your system does not have the include file + `stab.h'. If `USG' is defined, `NO_STAB_H' is assumed. + +`PATH_SEPARATOR' + Define this macro to be a C character constant representing the + character used to separate components in paths. The default value + is the colon character + +`DIR_SEPARATOR' + If your system uses some character other than slash to separate + directory names within a file specification, define this macro to + be a C character constant specifying that character. When GNU CC + displays file names, the character you specify will be used. GNU + CC will test for both slash and the character you specify when + parsing filenames. + +`OBJECT_SUFFIX' + Define this macro to be a C string representing the suffix for + object files on your machine. If you do not define this macro, + GNU CC will use `.o' as the suffix for object files. + +`EXECUTABLE_SUFFIX' + Define this macro to be a C string representing the suffix for + executable files on your machine. If you do not define this + macro, GNU CC will use the null string as the suffix for object + files. + +`COLLECT_EXPORT_LIST' + If defined, `collect2' will scan the individual object files + specified on its command line and create an export list for the + linker. Define this macro for systems like AIX, where the linker + discards object files that are not referenced from `main' and uses + export lists. + + In addition, configuration files for system V define `bcopy', +`bzero' and `bcmp' as aliases.

If your target does not + need to use the functions in `libgcc1.a', set this to empty. + *Note Interface::. + +`CROSS_LIBGCC1' + The rule to use to build `libgcc1.a' when building a cross + compiler. If your target does not need to use the functions in + `libgcc1.a', set this to empty. *Note Cross Runtime::. + +`LIBGCC2_CFLAGS' + Compiler flags to use when compiling `libgcc2.c'. + +`LIB2FUNCS_EXTRA' + A list of source file names to be compiled or assembled and + inserted into `libgcc.a'. + +`CRTSTUFF_T_CFLAGS' + Special flags used when compiling `crtstuff.c'. *Note + Initialization::. + +`CRTSTUFF_T_CFLAGS_S' + Special flags used when compiling `crtstuff.c' for shared linking. + Used if you use `crtbeginS.o' and `crtendS.o' in `EXTRA-PARTS'. + *Note Initialization::. + +`MULTILIB_OPTIONS' + For some targets, invoking GNU CC in different ways produces + objects that can not be linked together. For example, for some + targets GNU CC produces both big and little endian code. For + these targets, you must arrange for multiple versions of + `libgcc.a' to be compiled, one for each set of incompatible + options. When GNU CC invokes the linker, it arranges to link in + the right version of `libgcc.a', based on the command line options + used. + + The `MULTILIB_OPTIONS' macro lists the set of options for which + special versions of `libgcc.a' must be built. Write options that + are mutually incompatible side by side, separated by a slash. + Write options that may be used together separated by a space. The + build procedure will build all combinations of compatible options. + + For example, if you set `MULTILIB_OPTIONS' to `m68000/m68020 + msoft-float', `Makefile' will build special versions of `libgcc.a' + using the sets of options `-m68000', `-m68020', `-msoft-float', + `-m68000 -msoft-float', and `-m68020 -msoft-float'. + +`MULTILIB_DIRNAMES' + If `MULTILIB_OPTIONS' is used, this variable specifies the + directory names that should be used to hold the various libraries. + Write one element in `MULTILIB_DIRNAMES' for each element in + `MULTILIB_OPTIONS'. If `MULTILIB_DIRNAMES' is not used, the + default value will be `MULTILIB_OPTIONS', with all slashes treated + as spaces. + + For example, if `MULTILIB_OPTIONS' is specified as `m68000/m68020 + msoft-float', then the default value of `MULTILIB_DIRNAMES' is + `m68000 m68020 msoft-float'. You may specify a different value if + you desire a different set of directory names. + +`MULTILIB_MATCHES' + Sometimes the same option may be written in two different ways. + If an option is listed in `MULTILIB_OPTIONS', GNU CC needs to know + about any synonyms. In that case, set `MULTILIB_MATCHES' to a + list of items of the form `option=option' to describe all relevant + synonyms. For example, `m68000=mc68000 m68020=mc68020'. + +`MULTILIB_EXCEPTIONS' + Sometimes when there are multiple sets of `MULTILIB_OPTIONS' being + specified, there are combinations that should not be built. In + that case, set `MULTILIB_EXCEPTIONS' to be all of the switch + exceptions in shell case syntax that should not be built. + + For example, in the PowerPC embedded ABI support, it was not + desirable to build libraries that compiled with the + `-mcall-aixdesc' option and either of the `-mcall-aixdesc' or + `-mlittle' options at the same time, and therefore + `MULTILIB_EXCEPTIONS' is set to `*mrelocatable/*mcall-aixdesc* + *mlittle/*mcall-aixdesc*'. + +`MULTILIB_EXTRA_OPTS' + Sometimes it is desirable that when building multiple versions of + `libgcc.a' certain options should always be passed on to the + compiler.

The most effective approach known is to encourage +commercial redistributors to donate. + + Users of free software systems can boost the pace of development by +encouraging for-a-fee distributors to donate part of their selling price +to free software developers--the Free Software Foundation, and others. + + The way to convince distributors to do this is to demand it and +expect it from them. So when you compare distributors, judge them +partly by how much they give to free software development. Show +distributors they must compete to be the one who gives the most. + + To make this approach work, you must insist on numbers that you can +compare, such as, "We will donate ten dollars to the Frobnitz project +for each disk sold." Don't be satisfied with a vague promise, such as +"A portion of the profits are donated," since it doesn't give a basis +for comparison. + + Even a precise fraction "of the profits from this disk" is not very +meaningful, since creative accounting and unrelated business decisions +can greatly alter what fraction of the sales price counts as profit. +If the price you pay is $50, ten percent of the profit is probably less +than a dollar; it might be a few cents, or nothing at all. + + Some redistributors do development work themselves. This is useful +too; but to keep everyone honest, you need to inquire how much they do, +and what kind. Some kinds of development make much more long-term +difference than others. For example, maintaining a separate version of +a program contributes very little; maintaining the standard version of a +program for the whole community contributes much. Easy new ports +contribute little, since someone else would surely do them; difficult +ports such as adding a new CPU to the GNU C compiler contribute more; +major new features or packages contribute the most. + + By establishing the idea that supporting further development is "the +proper thing to do" when distributing free software for a fee, we can +assure a steady flow of resources into making more free software. + + Copyright (C) 1994 Free Software Foundation, Inc. + Verbatim copying and redistribution of this section is permitted + without royalty; alteration is not permitted. + + +File: gcc.info, Node: Look and Feel, Next: Copying, Prev: Funding, Up: Top + +Protect Your Freedom--Fight "Look And Feel" +******************************************* + + This section is a political message from the League for Programming + Freedom to the users of GNU CC. We have included it here because + the issue of interface copyright is important to the GNU project. + + Apple, Lotus, and now CDC have tried to create a new form of legal +monopoly: a copyright on a user interface. + + An interface is a kind of language--a set of conventions for +communication between two entities, human or machine. Until a few years +ago, the law seemed clear: interfaces were outside the domain of +copyright, so programmers could program freely and implement whatever +interface the users demanded. Imitating de-facto standard interfaces, +sometimes with improvements, was standard practice in the computer +field. These improvements, if accepted by the users, caught on and +became the norm; in this way, much progress took place. + + Computer users, and most software developers, were happy with this +state of affairs. However, large companies such as Apple and Lotus +would prefer a different system--one in which they can own interfaces +and thereby rid themselves of all serious competitors. They hope that +interface copyright will give them, in effect, monopolies on major +classes of software. + + Other large companies such as IBM and Digital also favor interface +monopolies, for the same reason: if languages become property, they +expect to own many de-facto standard languages. But Apple and Lotus are +the ones who have actually sued. Apple's lawsuit was defeated, for +reasons only partly related to the general issue of interface copyright. + + Lotus won lawsuits against two small companies, which were thus put +out of business. Then Lotus sued Borland; Lotus won in the trial court +(no surprise, since it was the same court that had ruled for Lotus twice +before), but the court of appeals ruled in favor of Borland, which was +assisted by a friend-of-the-court brief from the League for Programming +Freedom. + + Lotus appealed the case to the Supreme Court, which heard the case +but was unable to reach a decision. This failure means that the appeals +court decision stands, in one portion of the United States, and may +influence the other appeals courts, but it does not set a nationwide +precedent. The battle is not over, and it is not limited to the United +States. + + The battle is extending into other areas of software as well. In +1995 a company that produced a simulator for a CDC computer was shut +down by a copyright lawsuit, in which CDC charged that the simulator +infringed the copyright on the manuals for the computer. + + If the monopolists get their way, they will hobble the software +field: + + * Gratuitous incompatibilities will burden users. Imagine if each + car manufacturer had to design a different way to start, stop, and + steer a car. + + * Users will be "locked in" to whichever interface they learn; then + they will be prisoners of one supplier, who will charge a + monopolistic price. + + * Large companies have an unfair advantage wherever lawsuits become + commonplace. Since they can afford to sue, they can intimidate + smaller developers with threats even when they don't really have a + case. + + * Interface improvements will come slower, since incremental + evolution through creative partial imitation will no longer occur. + + If interface monopolies are accepted, other large companies are +waiting to grab theirs: + + * Adobe is expected to claim a monopoly on the interfaces of various + popular application programs, if Lotus ultimately wins the case + against Borland. + + * Open Computing magazine reported a Microsoft vice president as + threatening to sue people who imitate the interface of Windows. + + Users invest a great deal of time and money in learning to use +computer interfaces. Far more, in fact, than software developers +invest in developing *and even implementing* the interfaces. Whoever +can own an interface, has made its users into captives, and +misappropriated their investment. + + To protect our freedom from monopolies like these, a group of +programmers and users have formed a grass-roots political organization, +the League for Programming Freedom. + + The purpose of the League is to oppose monopolistic practices such as +interface copyright and software patents. The League calls for a return +to the legal policies of the recent past, in which programmers could +program freely. The League is not concerned with free software as an +issue, and is not affiliated with the Free Software Foundation. + + The League's activities include publicizing the issues, as is being +done here, and filing friend-of-the-court briefs on behalf of +defendants sued by monopolists. + + The League's membership rolls include Donald Knuth, the foremost +authority on algorithms, John McCarthy, inventor of Lisp, Marvin Minsky, +founder of the MIT Artificial Intelligence lab, Guy L. Steele, Jr., +author of well-known books on Lisp and C, as well as Richard Stallman, +the developer of GNU CC. Please join and add your name to the list. +Membership dues in the League are $42 per year for programmers, managers +and professionals; $10.50 for students; $21 for others. + + Activist members are especially important, but members who have no +time to give are also important. Surveys at major ACM conferences have +indicated a vast majority of attendees agree with the League on both +issues (interface copyrights and software patents). If just ten percent +of the programmers who agree with the League join the League, we will +probably triumph. + + To join, or for more information, send electronic mail to the +address `lpf@uunet.uu.net' or write to: + + League for Programming Freedom + 1 Kendall Square #143 + P.O.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it in +new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, +and (2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains a + notice placed by the copyright holder saying it may be distributed + under the terms of this General Public License. The "Program", + below, refers to any such program or work, and a "work based on + the Program" means either the Program or any derivative work under + copyright law: that is to say, a work containing the Program or a + portion of it, either verbatim or with modifications and/or + translated into another language. (Hereinafter, translation is + included without limitation in the term "modification".) Each + licensee is addressed as "you". + + Activities other than copying, distribution and modification are + not covered by this License; they are outside its scope. The act + of running the Program is not restricted, and the output from the + Program is covered only if its contents constitute a work based on + the Program (independent of having been made by running the + Program). Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's + source code as you receive it, in any medium, provided that you + conspicuously and appropriately publish on each copy an appropriate + copyright notice and disclaimer of warranty; keep intact all the + notices that refer to this License and to the absence of any + warranty; and give any other recipients of the Program a copy of + this License along with the Program. + + You may charge a fee for the physical act of transferring a copy, + and you may at your option offer warranty protection in exchange + for a fee. + + 2. You may modify your copy or copies of the Program or any portion + of it, thus forming a work based on the Program, and copy and + distribute such modifications or work under the terms of Section 1 + above, provided that you also meet all of these conditions: + + a. You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b. You must cause any work that you distribute or publish, that + in whole or in part contains or is derived from the Program + or any part thereof, to be licensed as a whole at no charge + to all third parties under the terms of this License. + + c. If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display + an announcement including an appropriate copyright notice and + a notice that there is no warranty (or else, saying that you + provide a warranty) and that users may redistribute the + program under these conditions, and telling the user how to + view a copy of this License. (Exception: if the Program + itself is interactive but does not normally print such an + announcement, your work based on the Program is not required + to print an announcement.) + + These requirements apply to the modified work as a whole. If + identifiable sections of that work are not derived from the + Program, and can be reasonably considered independent and separate + works in themselves, then this License, and its terms, do not + apply to those sections when you distribute them as separate + works. But when you distribute the same sections as part of a + whole which is a work based on the Program, the distribution of + the whole must be on the terms of this License, whose permissions + for other licensees extend to the entire whole, and thus to each + and every part regardless of who wrote it. + + Thus, it is not the intent of this section to claim rights or + contest your rights to work written entirely by you; rather, the + intent is to exercise the right to control the distribution of + derivative or collective works based on the Program. + + In addition, mere aggregation of another work not based on the + Program with the Program (or with a work based on the Program) on + a volume of a storage or distribution medium does not bring the + other work under the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, + under Section 2) in object code or executable form under the terms + of Sections 1 and 2 above provided that you also do one of the + following: + + a. Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of + Sections 1 and 2 above on a medium customarily used for + software interchange; or, + + b. Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a + medium customarily used for software interchange; or, + + c. Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with + such an offer, in accord with Subsection b above.) + + The source code for a work means the preferred form of the work for + making modifications to it. For an executable work, complete + source code means all the source code for all modules it contains, + plus any associated interface definition files, plus the scripts + used to control compilation and installation of the executable. + However, as a special exception, the source code distributed need + not include anything that is normally distributed (in either + source or binary form) with the major components (compiler, + kernel, and so on) of the operating system on which the executable + runs, unless that component itself accompanies the executable. + + If distribution of executable or object code is made by offering + access to copy from a designated place, then offering equivalent + access to copy the source code from the same place counts as + distribution of the source code, even though third parties are not + compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program + except as expressly provided under this License. Any attempt + otherwise to copy, modify, sublicense or distribute the Program is + void, and will automatically terminate your rights under this + License. However, parties who have received copies, or rights, + from you under this License will not have their licenses + terminated so long as such parties remain in full compliance. + + 5. You are not required to accept this License, since you have not + signed it. However, nothing else grants you permission to modify + or distribute the Program or its derivative works. These actions + are prohibited by law if you do not accept this License. + Therefore, by modifying or distributing the Program (or any work + based on the Program), you indicate your acceptance of this + License to do so, and all its terms and conditions for copying, + distributing or modifying the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the + Program), the recipient automatically receives a license from the + original licensor to copy, distribute or modify the Program + subject to these terms and conditions. You may not impose any + further restrictions on the recipients' exercise of the rights + granted herein. You are not responsible for enforcing compliance + by third parties to this License. + + 7. If, as a consequence of a court judgment or allegation of patent + infringement or for any other reason (not limited to patent + issues), conditions are imposed on you (whether by court order, + agreement or otherwise) that contradict the conditions of this + License, they do not excuse you from the conditions of this + License. If you cannot distribute so as to satisfy simultaneously + your obligations under this License and any other pertinent + obligations, then as a consequence you may not distribute the + Program at all. For example, if a patent license would not permit + royalty-free redistribution of the Program by all those who + receive copies directly or indirectly through you, then the only + way you could satisfy both it and this License would be to refrain + entirely from distribution of the Program. + + If any portion of this section is held invalid or unenforceable + under any particular circumstance, the balance of the section is + intended to apply and the section as a whole is intended to apply + in other circumstances. + + It is not the purpose of this section to induce you to infringe any + patents or other property right claims or to contest validity of + any such claims; this section has the sole purpose of protecting + the integrity of the free software distribution system, which is + implemented by public license practices. Many people have made + generous contributions to the wide range of software distributed + through that system in reliance on consistent application of that + system; it is up to the author/donor to decide if he or she is + willing to distribute software through any other system and a + licensee cannot impose that choice. + + This section is intended to make thoroughly clear what is believed + to be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in + certain countries either by patents or by copyrighted interfaces, + the original copyright holder who places the Program under this + License may add an explicit geographical distribution limitation + excluding those countries, so that distribution is permitted only + in or among countries not thus excluded. In such case, this + License incorporates the limitation as if written in the body of + this License. + + 9. The Free Software Foundation may publish revised and/or new + versions of the General Public License from time to time. Such + new versions will be similar in spirit to the present version, but + may differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the + Program specifies a version number of this License which applies + to it and "any later version", you have the option of following + the terms and conditions either of that version or of any later + version published by the Free Software Foundation. If the Program + does not specify a version number of this License, you may choose + any version ever published by the Free Software Foundation. + + 10. If you wish to incorporate parts of the Program into other free + programs whose distribution conditions are different, write to the + author to ask for permission. For software which is copyrighted + by the Free Software Foundation, write to the Free Software + Foundation; we sometimes make exceptions for this. Our decision + will be guided by the two goals of preserving the free status of + all derivatives of our free software and of promoting the sharing + and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO + WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE + LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT + HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT + WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT + NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND + FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE + QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE + PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY + SERVICING, REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN + WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY + MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE + LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, + INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR + INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF + DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU + OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY + OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN + ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + +How to Apply These Terms to Your New Programs +============================================= + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these +terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES. + Copyright (C) 19YY NAME OF AUTHOR + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA. + + Also add information on how to contact you by electronic and paper +mail. + + If the program is interactive, make it output a short notice like +this when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19YY NAME OF AUTHOR + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details + type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + + The hypothetical commands `show w' and `show c' should show the +appropriate parts of the General Public License. Of course, the +commands you use may be called something other than `show w' and `show +c'; they could even be mouse-clicks or menu items--whatever suits your +program. + + You should also get your employer (if you work as a programmer) or +your school, if any, to sign a "copyright disclaimer" for the program, +if necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + SIGNATURE OF TY COON, 1 April 1989 + Ty Coon, President of Vice + + This General Public License does not permit incorporating your +program into proprietary programs.

Use it in concert with @sc{gnu} +CC to analyze your programs to help create more efficient, faster +running code. You can use @code{gcov} as a profiling tool to help +discover where your optimization efforts will best affect your code. You +can also use @code{gcov} along with the other profiling tool, +@code{gprof}, to assess which parts of your code use the greatest amount +of computing time. + +Profiling tools help you analyze your code's performance. Using a +profiler such as @code{gcov} or @code{gprof}, you can find out some +basic performance statistics, such as: + +@itemize @bullet +@item +how often each line of code executes + +@item +what lines of code are actually executed + +@item +how much computing time each section of code uses +@end itemize + +Once you know these things about how your code works when compiled, you +can look at each module to see which modules should be optimized. +@code{gcov} helps you determine where to work on optimization. + +Software developers also use coverage testing in concert with +testsuites, to make sure software is actually good enough for a release. +Testsuites can verify that a program works as expected; a coverage +program tests to see how much of the program is exercised by the +testsuite. Developers can then determine what kinds of test cases need +to be added to the testsuites to create both better testing and a better +final product. + +You should compile your code without optimization if you plan to use +@code{gcov} because the optimization, by combining some lines of code +into one function, may not give you as much information as you need to +look for `hot spots' where the code is using a great deal of computer +time. Likewise, because @code{gcov} accumulates statistics by line (at +the lowest resolution), it works best with a programming style that +places only one statement on each line. If you use complicated macros +that expand to loops or to other control structures, the statistics are +less helpful---they only report on the line where the macro call +appears. If your complex macros behave like functions, you can replace +them with inline functions to solve this problem. + +@code{gcov} creates a logfile called @file{@var{sourcefile}.gcov} which +indicates how many times each line of a source file @file{@var{sourcefile}.c} +has executed. You can use these logfiles along with @code{gprof} to aid +in fine-tuning the performance of your programs. @code{gprof} gives +timing information you can use along with the information you get from +@code{gcov}. + +@code{gcov} works only on code compiled with @sc{gnu} CC.

These additional files are placed in the +directory where the source code is located. + +Running the program will cause profile output to be generated. For each +source file compiled with -fprofile-arcs, an accompanying @code{.da} +file will be placed in the source directory. + +Running @code{gcov} with your program's source file names as arguments +will now produce a listing of the code along with frequency of execution +for each line. For example, if your program is called @samp{tmp.c}, this +is what you see when you use the basic @code{gcov} facility: + +@smallexample +$ gcc -fprofile-arcs -ftest-coverage tmp.c +$ a.out +$ gcov tmp.c + 87.50% of 8 source lines executed in file tmp.c +Creating tmp.c.gcov. +@end smallexample + +The file @file{tmp.c.gcov} contains output from @code{gcov}. +Here is a sample: + +@smallexample + main() + @{ + 1 int i, total; + + 1 total = 0; + + 11 for (i = 0; i < 10; i++) + 10 total += i; + + 1 if (total != 45) + ###### printf ("Failure\n"); + else + 1 printf ("Success\n"); + 1 @} +@end smallexample + +@need 450 +When you use the @samp{-b} option, your output looks like this: + +@smallexample +$ gcov -b tmp.c + 87.50% of 8 source lines executed in file tmp.c + 80.00% of 5 branches executed in file tmp.c + 80.00% of 5 branches taken at least once in file tmp.c + 50.00% of 2 calls executed in file tmp.c +Creating tmp.c.gcov. +@end smallexample + +Here is a sample of a resulting @file{tmp.c.gcov} file: + +@smallexample + main() + @{ + 1 int i, total; + + 1 total = 0; + + 11 for (i = 0; i < 10; i++) +branch 0 taken = 91% +branch 1 taken = 100% +branch 2 taken = 100% + 10 total += i; + + 1 if (total != 45) +branch 0 taken = 100% + ###### printf ("Failure\n"); +call 0 never executed +branch 1 never executed + else + 1 printf ("Success\n"); +call 0 returns = 100% + 1 @} +@end smallexample + +For each basic block, a line is printed after the last line of the basic +block describing the branch or call that ends the basic block. There can +be multiple branches and calls listed for a single source line if there +are multiple basic blocks that end on that line. In this case, the +branches and calls are each given a number. There is no simple way to map +these branches and calls back to source constructs. In general, though, +the lowest numbered branch or call will correspond to the leftmost construct +on the source line. + +For a branch, if it was executed at least once, then a percentage +indicating the number of times the branch was taken divided by the +number of times the branch was executed will be printed. Otherwise, the +message ``never executed'' is printed. + +For a call, if it was executed at least once, then a percentage +indicating the number of times the call returned divided by the number +of times the call was executed will be printed. This will usually be +100%, but may be less for functions call @code{exit} or @code{longjmp}, +and thus may not return everytime they are called. + +The execution counts are cumulative. If the example program were +executed again without removing the @code{.da} file, the count for the +number of times each line in the source was executed would be added to +the results of the previous run(s). This is potentially useful in +several ways. For example, it could be used to accumulate data over a +number of program runs as part of a test verification suite, or to +provide more accurate long-term information over a large number of +program runs. + +The data in the @code{.da} files is saved immediately before the program +exits. For each source file compiled with -fprofile-arcs, the profiling +code first attempts to read in an existing @code{.da} file; if the file +doesn't match the executable (differing number of basic block counts) it +will ignore the contents of the file. It then adds in the new execution +counts and finally writes the data to the file. + +@node Gcov and Optimization +@section Using @code{gcov} with GCC Optimization + +If you plan to use @code{gcov} to help optimize your code, you must +first compile your program with two special @sc{gnu} CC options: +@samp{-fprofile-arcs -ftest-coverage}. Aside from that, you can use any +other @sc{gnu} CC options; but if you want to prove that every single line +in your program was executed, you should not compile with optimization +at the same time. On some machines the optimizer can eliminate some +simple code lines by combining them with other lines. For example, code +like this: + +@smallexample +if (a != b) + c = 1; +else + c = 0; +@end smallexample + +@noindent +can be compiled into one instruction on some machines. In this case, +there is no way for @code{gcov} to calculate separate execution counts +for each line because there isn't separate code for each line. Hence +the @code{gcov} output looks like this if you compiled the program with +optimization: + +@smallexample + 100 if (a != b) + 100 c = 1; + 100 else + 100 c = 0; +@end smallexample + +The output shows that this block of code, combined by optimization, +executed 100 times. In one sense this result is correct, because there +was only one instruction representing all four of these lines. However, +the output does not indicate how many times the result was 0 and how +many times the result was 1. + +@node Gcov Data Files +@section Brief description of @code{gcov} data files + +@code{gcov} uses three files for doing profiling. The names of these +files are derived from the original @emph{source} file by substituting +the file suffix with either @code{.bb}, @code{.bbg}, or @code{.da}. All +of these files are placed in the same directory as the source file, and +contain data stored in a platform-independent method. + +The @code{.bb} and @code{.bbg} files are generated when the source file +is compiled with the @sc{gnu} CC @samp{-ftest-coverage} option. The +@code{.bb} file contains a list of source files (including headers), +functions within those files, and line numbers corresponding to each +basic block in the source file. + +The @code{.bb} file format consists of several lists of 4-byte integers +which correspond to the line numbers of each basic block in the +file. Each list is terminated by a line number of 0. A line number of -1 +is used to designate that the source file name (padded to a 4-byte +boundary and followed by another -1) follows. In addition, a line number +of -2 is used to designate that the name of a function (also padded to a +4-byte boundary and followed by a -2) follows. + +The @code{.bbg} file is used to reconstruct the program flow graph for +the source file. It contains a list of the program flow arcs (possible +branches taken from one basic block to another) for each function which, +in combination with the @code{.bb} file, enables gcov to reconstruct the +program flow. + +In the @code{.bbg} file, the format is: +@smallexample + number of basic blocks for function #0 (4-byte number) + total number of arcs for function #0 (4-byte number) + count of arcs in basic block #0 (4-byte number) + destination basic block of arc #0 (4-byte number) + flag bits (4-byte number) + destination basic block of arc #1 (4-byte number) + flag bits (4-byte number) + ... + destination basic block of arc #N (4-byte number) + flag bits (4-byte number) + count of arcs in basic block #1 (4-byte number) + destination basic block of arc #0 (4-byte number) + flag bits (4-byte number) + ... +@end smallexample + +A -1 (stored as a 4-byte number) is used to separate each function's +list of basic blocks, and to verify that the file has been read +correctly. + +The @code{.da} file is generated when a program containing object files +built with the @sc{gnu} CC @samp{-fprofile-arcs} option is executed. A +separate @code{.da} file is created for each source file compiled with +this option, and the name of the @code{.da} file is stored as an +absolute pathname in the resulting object file. This path name is +derived from the source file name by substituting a @code{.da} suffix. + +The format of the @code{.da} file is fairly simple. The first 8-byte +number is the number of counts in the file, followed by the counts +(stored as 8-byte numbers). Each count corresponds to the number of +times each arc in the program is executed. The counts are cumulative; +each time the program is executed, it attemps to combine the existing +@code{.da} files with the new counts for this invocation of the +program. It ignores the contents of any @code{.da} files whose number of +arcs doesn't correspond to the current program, and merely overwrites +them instead. + +All three of these files use the functions in @code{gcov-io.h} to store +integers; the functions in this header provide a machine-independent +mechanism for storing and retrieving data from a stream. + |
