See below for a [2]list of systems which are - obsoleted in this release. - * Checking for null format arguments has been decoupled from the - rest of the format checking mechanism. Programs which use the - format attribute may regain this functionality by using the new - [3]nonnull function attribute. Note that all functions for which - GCC has a built-in format attribute, an appropriate built-in - nonnull attribute is also applied. - * The DWARF (version 1) debugging format has been deprecated and - will be removed in a future version of GCC. Version 2 of the DWARF - debugging format will continue to be supported for the foreseeable - future. - * The C and Objective-C compilers no longer accept the "Naming - Types" extension (typedef foo = bar); it was already unavailable - in C++. Code which uses it will need to be changed to use the - "typeof" extension instead: typedef typeof(bar) foo. (We have - removed this extension without a period of deprecation because it - has caused the compiler to crash since version 3.0 and no one - noticed until very recently. Thus we conclude it is not in - widespread use.) - * The -traditional C compiler option has been removed. It was - deprecated in 3.1 and 3.2. (Traditional preprocessing remains - available.) The <varargs.h> header, used for writing variadic - functions in traditional C, still exists but will produce an error - message if used. - * GCC 3.3.1 automatically places zero-initialized variables in the - .bss section on some operating systems. Versions of GNU Emacs up - to (and including) 21.3 will not work correctly when using this - optimization; you can use -fno-zero-initialized-in-bss to disable - it. - -General Optimizer Improvements - - * A new scheme for accurately describing processor pipelines, the - [4]DFA scheduler, has been added. - * Pavel Nejedly, Charles University Prague, has contributed new file - format used by the edge coverage profiler (-fprofile-arcs). - The new format is robust and diagnoses common mistakes where - profiles from different versions (or compilations) of the program - are combined resulting in nonsensical profiles and slow code to - produced with profile feedback. Additionally this format allows - extra data to be gathered. Currently, overall statistics are - produced helping optimizers to identify hot spots of a program - globally replacing the old intra-procedural scheme and resulting - in better code. Note that the gcov tool from older GCC versions - will not be able to parse the profiles generated by GCC 3.3 and - vice versa. - * Jan Hubicka, SuSE Labs, has contributed a new superblock formation - pass enabled using -ftracer. This pass simplifies the control flow - of functions allowing other optimizations to do better job. - He also contributed the function reordering pass - (-freorder-functions) to optimize function placement using profile - feedback. - -New Languages and Language specific improvements - - C/ObjC/C++ - - * The preprocessor now accepts directives within macro arguments. It - processes them just as if they had not been within macro - arguments. - * The separate ISO and traditional preprocessors have been - completely removed. The front-end handles either type of - preprocessed output if necessary. - * In C99 mode preprocessor arithmetic is done in the precision of - the target's intmax_t, as required by that standard. - * The preprocessor can now copy comments inside macros to the output - file when the macro is expanded. This feature, enabled using the - -CC option, is intended for use by applications which place - metadata or directives inside comments, such as lint. - * The method of constructing the list of directories to be searched - for header files has been revised. If a directory named by a -I - option is a standard system include directory, the option is - ignored to ensure that the default search order for system - directories and the special treatment of system header files are - not defeated. - * A few more [5]ISO C99 features now work correctly. - * A new function attribute, nonnull, has been added which allows - pointer arguments to functions to be specified as requiring a - non-null value. The compiler currently uses this information to - issue a warning when it detects a null value passed in such an - argument slot. - * A new type attribute, may_alias, has been added. Accesses to - objects with types with this attribute are not subjected to - type-based alias analysis, but are instead assumed to be able to - alias any other type of objects, just like the char type. - - C++ - - * Type based alias analysis has been implemented for C++ aggregate - types. - - Objective-C - - * Generate an error if Objective-C objects are passed by value in - function and method calls. - * When -Wselector is used, check the whole list of selectors at the - end of compilation, and emit a warning if a @selector() is not - known. - * Define __NEXT_RUNTIME__ when compiling for the NeXT runtime. - * No longer need to include objc/objc-class.h to compile self calls - in class methods (NeXT runtime only). - * New -Wundeclared-selector option. - * Removed selector bloating which was causing object files to be 10% - bigger on average (GNU runtime only). - * Using at run time @protocol() objects has been fixed in certain - situations (GNU runtime only). - * Type checking has been fixed and improved in many situations - involving protocols. - - Java - - * The java.sql and javax.sql packages now implement the JDBC 3.0 - (JDK 1.4) API. - * The JDK 1.4 assert facility has been implemented. - * The bytecode interpreter is now direct threaded and thus faster. - - Fortran - - * Fortran improvements are listed in [6]the Fortran documentation. - - Ada - - * Ada tasking now works with glibc 2.3.x threading libraries. - -New Targets and Target Specific Improvements - - * The following changes have been made to the HP-PA port: - + The port now defaults to scheduling for the PA8000 series of - processors. - + Scheduling support for the PA7300 processor has been added. - + The 32-bit port now supports weak symbols under HP-UX 11. - + The handling of initializers and finalizers has been improved - under HP-UX 11. The 64-bit port no longer uses collect2. - + Dwarf2 EH support has been added to the 32-bit linux port. - + ABI fixes to correct the passing of small structures by - value. - * The SPARC, HP-PA, SH4, and x86/pentium ports have been converted - to use the DFA processor pipeline description. - * The following NetBSD configurations for the SuperH processor - family have been added: - + SH3, big-endian, sh-*-netbsdelf* - + SH3, little-endian, shle-*-netbsdelf* - + SH5, SHmedia, big-endian, 32-bit default, sh5-*-netbsd* - + SH5, SHmedia, little-endian, 32-bit default, sh5le-*-netbsd* - + SH5, SHmedia, big-endian, 64-bit default, sh64-*-netbsd* - + SH5, SHmedia, little-endian, 64-bit default, sh64le-*-netbsd* - * The following changes have been made to the IA-32/x86-64 port: - + SSE2 and 3dNOW! intrinsics are now supported. - + Support for thread local storage has been added to the IA-32 - and x86-64 ports. - + The x86-64 port has been significantly improved. - * The following changes have been made to the MIPS port: - + All configurations now accept the -mabi switch. Note that you - will need appropriate multilibs for this option to work - properly. - + ELF configurations will always pass an ABI flag to the - assembler, except when the MIPS EABI is selected. - + -mabi=64 no longer selects MIPS IV code. - + The -mcpu option, which was deprecated in 3.1 and 3.2, has - been removed from this release. - + -march now changes the core ISA level. In previous releases, - it would change the use of processor-specific extensions, but - would leave the core ISA unchanged. For example, mips64-elf - -march=r8000 will now generate MIPS IV code. - + Under most configurations, -mipsN now acts as a synonym for - -march. - + There are some new preprocessor macros to describe the -march - and -mtune settings. See the documentation of those options - for details. - + Support for the NEC VR-Series processors has been added. This - includes the 54xx, 5500, and 41xx series. - + Support for the Sandcraft sr71k processor has been added. - * The following changes have been made to the S/390 port: - + Support to build the Java runtime libraries has been added. - Java is now enabled by default on s390-*-linux* and - s390x-*-linux* targets. - + Multilib support for the s390x-*-linux* target has been - added; this allows to build 31-bit binaries using the -m31 - option. - + Support for thread local storage has been added. - + Inline assembler code may now use the 'Q' constraint to - specify memory operands without index register. - + Various platform-specific performance improvements have been - implemented; in particular, the compiler now uses the BRANCH - ON COUNT family of instructions and makes more frequent use - of the TEST UNDER MASK family of instructions. - * The following changes have been made to the PowerPC port: - + Support for IBM Power4 processor added. - + Support for Motorola e500 SPE added. - + Support for AIX 5.2 added. - + Function and Data sections now supported on AIX. - + Sibcall optimizations added. - * The support for H8 Tiny is added to the H8/300 port with -mn. - -Obsolete Systems - - Support for a number of older systems has been declared obsolete in - GCC 3.3.

This should make - adding a new front end clearer and easier. - * One effect of removing the separate preprocessor is a small - increase in the robustness of the compiler in general, and the - maintainability of target descriptions. Previously target-specific - built-in macros and others, such as __FAST_MATH__, had to be - handled with so-called specs that were hard to maintain. Often - they would fail to behave properly when conflicting options were - supplied on the command line, and define macros in the user's - namespace even when strict ISO compliance was requested. - Integrating the preprocessor has cleanly solved these issues. - * The Makefile suite now supports redirection of make install by - means of the variable DESTDIR. - _________________________________________________________________ - -GCC 3.3 - - Detailed release notes for the GCC 3.3 release follow. -

- GCC 3.2 Release Series - - April 25, 2003 - - The [1]GNU project and the GCC developers are pleased to announce the - release of GCC 3.2.3. - - The purpose of the GCC 3.2 release series is to provide a stable - platform for OS distributors to use building their next releases. A - primary objective was to stabilize the C++ ABI; we believe that the - interface to the compiler and the C++ standard library are now - relatively stable. - - Be aware that C++ code compiled by GCC 3.2.x will (in general) not - interoperate with code compiled by GCC 3.1.1 or earlier. - - Please refer to our [2]detailed list of news, caveats, and bug-fixes - for further information. - -Release History - - GCC 3.2.3 - April 25, 2003 ([3]changes) - - GCC 3.2.2 - February 5, 2003 ([4]changes) - - GCC 3.2.1 - November 19, 2002 ([5]changes) - - GCC 3.2 - August 14, 2002 ([6]changes) - -References and Acknowledgements - - GCC used to stand for the GNU C Compiler, but since the compiler - supports several other languages aside from C, it now stands for the - GNU Compiler Collection. - - A list of [7]successful builds is updated as new information becomes - available. - - The GCC developers would like to thank the numerous people that have - contributed new features, improvements, bug fixes, and other changes - as well as test results to GCC. This [8]amazing group of volunteers is - what makes GCC successful. - - For additional information about GCC please refer to the [9]GCC - project web site or contact the [10]GCC development mailing list. - - To obtain GCC please use [11]our mirror sites, one of the [12]GNU - mirror sites, or [13]our CVS server. - _________________________________________________________________ - - Please send FSF & GNU inquiries & questions to [14]gnu@gnu.org. There - are also [15]other ways to contact the FSF. - - These pages are maintained by [16]the GCC team. - - - For questions related to the use of GCC, please consult these web - pages and the [17]GCC manuals. If that fails, the - [18]gcc-help@gcc.gnu.org mailing list might help. - Please send comments on these web pages and the development of GCC - to our public developer mailing list at [19]gcc@gnu.org or - [20]gcc@gcc.gnu.org. - - Copyright (C) Free Software Foundation, Inc., 59 Temple Place - Suite - 330, Boston, MA 02111, USA. - - Verbatim copying and distribution of this entire article is permitted - in any medium, provided this notice is preserved. - - Last modified 2003-08-28 [21]Valid XHTML 1.0 - -References - - 1. http://www.gnu.org/ - 2. http://gcc.gnu.org/gcc-3.2/changes.html - 3. http://gcc.gnu.org/gcc-3.2/changes.html#3.2.3 - 4. http://gcc.gnu.org/gcc-3.2/changes.html#3.2.2 - 5. http://gcc.gnu.org/gcc-3.2/changes.html#3.2.1 - 6. http://gcc.gnu.org/gcc-3.2/changes.html#3.2 - 7. http://gcc.gnu.org/gcc-3.2/buildstat.html - 8. http://gcc.gnu.org/onlinedocs/gcc/Contributors.html - 9. http://gcc.gnu.org/index.html - 10. mailto:gcc@gcc.gnu.org - 11. http://gcc.gnu.org/mirrors.html - 12. http://www.gnu.org/order/ftp.html - 13. http://gcc.gnu.org/cvs.html - 14. mailto:gnu@gnu.org - 15. http://www.gnu.org/home.html#ContactInfo - 16. http://gcc.gnu.org/about.html - 17. http://gcc.gnu.org/onlinedocs/ - 18. mailto:gcc-help@gcc.gnu.org - 19. mailto:gcc@gnu.org - 20. mailto:gcc@gcc.gnu.org - 21. http://validator.w3.org/check/referer -====================================================================== -http://gcc.gnu.org/gcc-3.2/changes.html - - GCC 3.2 Release Series - Changes, New Features, and Fixes - - The latest release in the 3.2 release series is [1]GCC 3.2.3. - -Caveats and New Features - - Caveats - - * The C++ compiler does not correctly zero-initialize - pointers-to-data members. You must explicitly initialize them. For - example: int S::*m(0); will work, but depending on - default-initialization to zero will not work. This bug cannot be - fixed in GCC 3.2 without inducing unacceptable risks. It will be - fixed in GCC 3.3. - * This GCC release is based on the GCC 3.1 sourcebase, and thus has - all the [2]changes in the GCC 3.1 series. In addition, GCC 3.2 has - a number of C++ ABI fixes which make its C++ compiler generate - binary code which is incompatible with the C++ compilers found in - earlier GCC releases, including GCC 3.1 and GCC 3.1.1. - - Frontend Enhancements - - C/C++/Objective-C - - * The method of constructing the list of directories to be searched - for header files has been revised. If a directory named by a -I - option is a standard system include directory, the option is - ignored to ensure that the default search order for system - directories and the special treatment of system header files are - not defeated. - * The C and Objective-C compilers no longer accept the "Naming - Types" extension (typedef foo = bar); it was already unavailable - in C++. Code which uses it will need to be changed to use the - "typeof" extension instead: typedef typeof(bar) foo. (We have - removed this extension without a period of deprecation because it - has caused the compiler to crash since version 3.0 and no one - noticed until very recently. Thus we conclude it is not in - widespread use.) - - C++ - - * There are now no known differences between the C++ ABI implemented - in GCC and the multi-vendor standard. We believe that the ABI for - the C++ standard library is now stable and will not change in - future versions of the compiler.

Previously the optimization prefetched random - blocks of memory for most targets except for i386. - * The Java compiler now compiles Java programs much faster and also - works with parallel make. - * Nested functions have been fixed for mips*-*-netbsd*. - * Some missing floating point support routines have beed added for - mips*-*-netbsd*. - * This [1]message gives additional information about the bugs fixed - in this release. - -Caveats - - * The -traditional C compiler option has been deprecated and will be - removed in GCC 3.3. (It remains possible to preprocess non-C code - with the traditional preprocessor.) - * The default debugging format for most ELF platforms (including - GNU/Linux and FreeBSD; notable exception is Solaris) has changed - from stabs to DWARF2. This requires GDB 5.1.1 or later. - -General Optimizer Improvements - - * Jan Hubicka, SuSE Labs, together with Richard Henderson, Red Hat, - and Andreas Jaeger, SuSE Labs, has contributed [2]infrastructure - for profile driven optimizations. - Options -fprofile-arcs and -fbranch-probabilities can now be used - to improve speed of the generated code by profiling the actual - program behaviour on typical runs. In the absence of profile info - the compiler attempts to guess the profile statically. - * [3]SPEC2000 and SPEC95 benchmark suites are now used daily to - monitor performance of the generated code. - According to the SPECInt2000 results on an AMD Athlon CPU, the - code generated by GCC 3.1 is 6% faster on the average (8.2% faster - with profile feedback) compared to GCC 3.0. The code produced by - GCC 3.0 is about 2.1% faster compared to 2.95.3. Tests were done - using the -O2 -march=athlon command-line options. - * Alexandre Oliva, of Red Hat, has generalized the tree inlining - infrastructure developed by CodeSourcery, LLC for the C++ front - end, so that it is now used in the C front end too. Inlining - functions as trees exposes them earlier to the compiler, giving it - more opportunities for optimization. - * Support for data prefetching instructions has been added to the - GCC back end and several targets. A new __builtin_prefetch - intrinsic is available to explicitly insert prefetch instructions - and experimental support for loop array prefetching has been added - (see -fprefetch-loop-array documentation). - * Support for emitting debugging information for macros has been - added for DWARF2. It is activated using -g3. - -New Languages and Language specific improvements - - C/C++ - - * A few more [4]ISO C99 features. - * The preprocessor is 10-50% faster than the preprocessor in GCC - 3.0. - * The preprocessor's symbol table has been merged with the symbol - table of the C, C++ and Objective-C front ends. - * The preprocessor consumes less memory than the preprocessor in GCC - 3.0, often significantly so. On normal input files, it typically - consumes less memory than pre-3.0 cccp-based GCC, too. - - C++ - - * -fhonor-std and -fno-honor-std have been removed. -fno-honor-std - was a workaround to allow std compliant code to work with the - non-std compliant libstdc++-v2. libstdc++-v3 is std compliant. - * The C++ ABI has been fixed so that void (A::*)() const is mangled - as "M1AKFvvE", rather than "MK1AFvvE" as before. This change only - affects pointer to cv-qualified member function types. - * The C++ ABI has been changed to correctly handle this code: - struct A { - void operator delete[] (void *, size_t); - }; - - struct B : public A { - }; - - new B[10]; - - The amount of storage allocated for the array will be greater than - it was in 3.0, in order to store the number of elements in the - array, so that the correct size can be passed to operator delete[] - when the array is deleted. Previously, the value passed to - operator delete[] was unpredictable. - This change will only affect code that declares a two-argument - operator delete[] with a second parameter of type size_t in a base - class, and does not override that definition in a derived class. - * The C++ ABI has been changed so that: - struct A { - void operator delete[] (void *, size_t); - void operator delete[] (void *); - }; - - does not cause unnecessary storage to be allocated when an array - of A objects is allocated. - This change will only affect code that declares both of these - forms of operator delete[], and declared the two-argument form - before the one-argument form. - * The C++ ABI has been changed so that when a parameter is passed by - value, any cleanup for that parameter is performed in the caller, - as specified by the ia64 C++ ABI, rather than the called function - as before. As a result, classes with a non-trivial destructor but - a trivial copy constructor will be passed and returned by - invisible reference, rather than by bitwise copy as before. - * G++ now supports the "named return value optimization": for code - like - A f () { - A a; - ... - return a; - } - - G++ will allocate a in the return value slot, so that the return - becomes a no-op. For this to work, all return statements in the - function must return the same variable. - * Improvements to the C++ library are listed in [5]the libstdc++-v3 - FAQ. - - Objective-C - - * Annoying linker warnings (due to incorrect code being generated) - have been fixed. - * If a class method cannot be found, the compiler no longer issues a - warning if a corresponding instance method exists in the root - class. - * Forward @protocol declarations have been fixed. - * Loading of categories has been fixed in certain situations (GNU - run time only). - * The class lookup in the run-time library has been rewritten so - that class method dispatch is more than twice as fast as it used - to be (GNU run time only). - - Java - - * libgcj now includes RMI, java.lang.ref.*, javax.naming, and - javax.transaction. - * Property files and other system resources can be compiled into - executables which use libgcj using the new gcj --resource feature. - * libgcj has been ported to more platforms. In particular there is - now a mostly-functional mingw32 (Windows) target port. - * JNI and CNI invocation interfaces were implemented, so - gcj-compiled Java code can now be called from a C/C++ application. - * gcj can now use builtin functions for certain known methods, for - instance Math.cos. - * gcj can now automatically remove redundant array-store checks in - some common cases. - * The --no-store-checks optimization option was added. This can be - used to omit runtime store checks for code which is known not to - throw ArrayStoreException - * The following third party interface standards were added to - libgcj: org.w3c.dom and org.xml.sax. - * java.security has been merged with GNU Classpath. The new package - is now JDK 1.2 compliant, and much more complete. - * A bytecode verifier was added to the libgcj interpreter. - * java.lang.Character was rewritten to comply with the Unicode 3.0 - standard, and improve performance. - * Partial support for many more locales was added to libgcj. - * Socket timeouts have been implemented. - * libgcj has been merged into a single shared library. There are no - longer separate shared libraries for the garbage collector and - zlib. - * Several performance improvements were made to gcj and libgcj: - + Hash synchronization (thin locks) - + A special allocation path for finalizer-free objects - + Thread-local allocation - + Parallel GC, and other GC tweaks - - Fortran - - Fortran improvements are listed in [6]the Fortran documentation. - - Ada - - [7]Ada Core Technologies, Inc, has contributed its GNAT Ada 95 front - end and associated tools. The GNAT compiler fully implements the Ada - language as defined by the ISO/IEC 8652 standard. - - Please note that the integration of the Ada front end is still work in - progress. - -New Targets and Target Specific Improvements - - * Hans-Peter Nilsson has contributed a port to [8]MMIX, the CPU - architecture used in new editions of Donald E. Knuth's The Art of - Computer Programming. - * [9]Axis Communications has contributed its port to the CRIS CPU - architecture, used in the ETRAX system-on-a-chip series. See - [10]Axis' developer site for technical information. - * Alexandre Oliva, of Red Hat, has contributed a port to the - [11]SuperH SH5 64-bit RISC microprocessor architecture, extending - the existing SH port. - * UltraSPARC is fully supported in 64-bit mode. The option -m64 - enables it. - * For compatibility with the Sun compiler #pragma redefine_extname - has been implemented on Solaris. - * The x86 back end has had some noticeable work done to it. - + SuSE Labs developers Jan Hubicka, Bo Thorsen and Andreas - Jaeger have contributed a port to the AMD x86-64 - architecture. For more information on x86-64 see - [12]http://www.x86-64.org. - + The compiler now supports MMX, 3DNow!, SSE, and SSE2 - instructions. Options -mmmx, -m3dnow, -msse, and -msse2 will - enable the respective instruction sets. Intel C++ compatible - MMX/3DNow!/SSE intrinsics are implemented. SSE2 intrinsics - will be added in next major release. - + Following those improvements, targets for Pentium MMX, K6-2, - K6-3, Pentium III, Pentium 4, and Athlon 4 Mobile/XP/MP were - added. Refer to the documentation on -march= and -mcpu= - options for details. - + For those targets that support it, -mfpmath=sse will cause - the compiler to generate SSE/SSE2 instructions for floating - point math instead of x87 instructions. Usually, this will - lead to quicker code -- especially on the Pentium 4.

This allows the compiler to assume the strictest aliasing - rules applicable to the language being compiled. For C and C++, - this activates optimizations based on the type of expressions. - This optimization may thus break old, non-compliant code. - * Enumerations are now properly promoted to int in function - parameters and function returns. Normally this change is not - visible, but when using -fshort-enums this is an ABI change. - * The undocumented extension that allowed C programs to have a label - at the end of a compound statement has been deprecated and may be - removed in a future version. Programs that now generate a warning - about this may be fixed by adding a null statement (a single - semicolon) after the label. - * The poorly documented extension that allowed string constants in - C, C++ and Objective C to contain unescaped newlines has been - deprecated and may be removed in a future version. Programs using - this extension may be fixed in several ways: the bare newline may - be replaced by \n, or preceded by \n\, or string concatenation may - be used with the bare newline preceded by \n" and " placed at the - start of the next line. - * The Chill compiler is not included in GCC 3.0, because of the lack - of a volunteer to convert it to use garbage collection. - * Certain non-standard iostream methods from earlier versions of - libstdc++ are not included in libstdc++ v3, i.e. filebuf::attach, - ostream::form, and istream::gets. Here are workaround hints for: - [1]ostream::form, [2]filebuf::attach. - * The new C++ ABI is not yet fully supported by current (as of - 2001-07-01) releases and development versions of GDB, or any - earlier versions. There is a problem setting breakpoints by line - number, and other related issues that have been fixed in GCC 3.0 - but not yet handled in GDB: - [3]http://gcc.gnu.org/ml/gcc-bugs/2001-06/msg00421.html - _________________________________________________________________ - - Please send FSF & GNU inquiries & questions to [4]gnu@gnu.org.

This - is particularly noticeable when compiling older versions of the - Linux kernel (2.0.xx). Please refer to the FAQ (as shipped with - GCC 2.95) for more information on this issue. - * GCC 2.95 implements type based alias analysis to disambiguate - memory references. Some programs, particularly the Linux kernel - violate ANSI/ISO aliasing rules and therefore may not operate - correctly when compiled with GCC 2.95. Please refer to the FAQ (as - shipped with GCC 2.95) for more information on this issue. - * GCC 2.95 has a known bug in its handling of complex variables for - 64bit targets. Instead of silently generating incorrect code, GCC - 2.95 will issue a fatal error for situations it can not handle. - This primarily affects the Fortran community as Fortran makes more - use of complex variables than C or C++. - * GCC 2.95 has an integrated libstdc++, but does not have an - integrated libg++. Furthermore old libg++ releases will not work - with GCC 2.95. You can retrieve a recent copy of libg++ from the - [1]GCC ftp server. - Note most C++ programs only need libstdc++. - * Exception handling may not work with shared libraries, - particularly on alphas, hppas, rs6000/powerpc and mips based - platforms. Exception handling is known to work on x86 GNU/Linux - platforms with shared libraries. - * In general, GCC 2.95 is more rigorous about rejecting invalid C++ - code or deprecated C++ constructs than G++ 2.7, G++ 2.8, EGCS 1.0, - or EGCS 1.1. As a result it may be necessary to fix C++ code - before it will compile with GCC 2.95. - * G++ is also converting toward the ISO C++ standard; as a result - code which was previously valid (and thus accepted by other - compilers and older versions of g++) may no longer be accepted. - The flag -fpermissive may allow some non-conforming code to - compile with GCC 2.95. - * GCC 2.95 compiled C++ code is not binary compatible with EGCS - 1.1.x, EGCS 1.0.x or GCC 2.8.x. - * GCC 2.95 does not have changes from the GCC 2.8 tree that were - made between Sept 30, 1998 and April 30, 1999 (the official end of - the GCC 2.8 project). Future GCC releases will include all the - changes from the defunct GCC 2.8 sources. - _________________________________________________________________ - - Please send FSF & GNU inquiries & questions to [2]gnu@gnu.org.

By providing more accurate information - to the priority based allocator, we get better register - allocation. - * The register reloading phase of the compiler optimizes spill code - much better than in previous releases. - * Some bad interactions between the register allocator and - instruction scheduler have been fixed, resulting in much better - code for certain programs. Additionally, we have tuned the - scheduler in various ways to improve performance of generated code - for some architectures. - * The compiler's branch shortening algorithms have been - significantly improved to work better on targets which align jump - targets. - * The compiler now supports -Os to prefer optimizing for code space - over optimizing for code speed. - * The compiler will now totally eliminate library calls which - compute constant values. This primarily helps targets with no - integer div/mul support and targets without floating point - support. - * The compiler now supports an extensive "--help" option. - * cpplib has been greatly improved and may be suitable for limited - use. - * Memory footprint for the compiler has been significantly reduced - for some pathological cases. - * The time to build EGCS has been improved for certain targets - (particularly the alpha and mips platforms). - * Many infrastructure improvements throughout the compiler, plus the - usual mountain of bugfixes and minor improvements. - * Target dependent improvements: - + SPARC port now includes V8 plus and V9 support as well as - performance tuning for Ultra class machines. The SPARC port - now uses the Haifa scheduler. - + Alpha port has been tuned for the EV6 processor and has an - optimized expansion of memcpy/bzero. The Alpha port now uses - the Haifa scheduler. - + RS6000/PowerPC: support for the Power64 architecture and AIX - 4.3. The RS6000/PowerPC port now uses the Haifa scheduler. - + x86: Alignment of static store data and jump targets is per - Intel recommendations now. Various improvements throughout - the x86 port to improve performance on Pentium processors - (including improved epilogue sequences for Pentium chips and - backend improvements which should help register allocation on - all x86 variants. Conditional move support has been fixed and - enabled for PPro processors. The x86 port also better - supports 64bit operations now.

Furthermore old libg++ releases will not work with EGCS; - HJ Lu has made a libg++-2.8.1.2 snapshot available which may work - with EGCS. - Note most C++ programs only need libstdc++. - * Exception handling may not work with shared libraries, - particularly on alphas, hppas, rs6000/powerpc and mips based - platforms. Exception handling is known to work on x86-linux - platforms with shared libraries. - * Some versions of the Linux kernel have bugs which prevent them - from being compiled or from running when compiled by EGCS. See the - FAQ (as shipped with EGCS 1.1) for additional information. - * In general, EGCS is more rigorous about rejecting invalid C++ code - or deprecated C++ constructs than g++-2.7, g++-2.8 or EGCS 1.0. As - a result it may be necessary to fix C++ code before it will - compile with EGCS. - * G++ is also converting toward the ISO C++ standard; as a result - code which was previously valid (and thus accepted by other - compilers and older versions of g++) may no longer be accepted. - * EGCS 1.1 compiled C++ code is not binary compatible with EGCS - 1.0.x or GCC 2.8.x due to changes necessary to support thread safe - exception handling. - _________________________________________________________________ - - Please send FSF & GNU inquiries & questions to [1]gnu@gnu.org.

Changes since the - EGCS 1.0 release: - * Add support for Red Hat 5.0 Linux and better support for Linux - systems using glibc2. - Many programs failed to link when compiled with EGCS 1.0 on Red - Hat 5.0 or on systems with newer versions of glibc2. EGCS 1.0.1 - should fix these problems. - * Compatibility with both EGCS 1.0 and GCC 2.8 libgcc exception - handling interfaces. - To avoid future compatibility problems, we strongly urge anyone - who is planning on distributing shared libraries that contain C++ - code to upgrade to EGCS 1.0.1 first. - Soon after EGCS 1.0 was released, the GCC developers made some - incompatible changes in libgcc's exception handling interfaces. - These changes were needed to solve problems on some platforms. - This means that GCC 2.8.0, when released, will not be seamlessly - compatible with shared libraries built by EGCS 1.0. The reason is - that the libgcc.a in GCC 2.8.0 will not contain a function needed - by the old interface. - The result of this is that there may be compatibility problems - with shared libraries built by EGCS 1.0 when used with GCC 2.8.0. - With EGCS 1.0.1, generated code uses the new (GCC 2.8.0) - interface, and libgcc.a has the support routines for both the old - and the new interfaces (so EGCS 1.0.1 and EGCS 1.0 code can be - freely mixed, and EGCS 1.0.1 and GCC 2.8.0 code can be freely - mixed). - The maintainers of GCC 2.x have decided against including seamless - support for the old interface in 2.8.0, since it was never - "official", so to avoid future compatibility problems we recommend - against distributing any shared libraries built by EGCS 1.0 that - contain C++ code (upgrade to 1.0.1 and use that). - * Various bugfixes in the x86, hppa, mips, and rs6000/ppc backends. - The x86 changes fix code generation errors exposed when building - glibc2 and the Linux dynamic linker (ld.so). - The hppa change fixes a compiler abort when configured for use - with RTEMS. - The MIPS changes fix problems with the definition of LONG_MAX on - newer systems, allow for command line selection of the target ABI, - and fix one code generation problem. - The rs6000/ppc change fixes some problems with passing structures - to varargs/stdarg functions. - * A few machine independent bugfixes, mostly to fix code generation - errors when building Linux kernels or glibc. - * Fix a few critical exception handling and template bugs in the C++ - compiler. - * Fix Fortran namelist bug on alphas. - * Fix build problems on x86-solaris systems. - - An important goal of EGCS is to allow wide scale testing of new - features and optimizations which are still under development. However, - EGCS has been carefully tested and should be comparable in quality to - most GCC releases. - - EGCS 1.0.1 is based on an August 2, 1997 snapshot of the GCC 2.8 - development sources; it contains nearly all of the new features found - in GCC 2.8. - - EGCS also contains many improvements and features not found in GCC 2.7 - and even the soon to be released GCC 2.8 compilers. - * Integrated C++ runtime libraries, including support for most major - linux systems! - * The integrated libstdc++ library includes a verbatim copy of SGI's - STL release. - * Integrated GNU Fortran compiler - * New instruction scheduler - * New alias analysis code - - See the [1]new features page for a more complete list of new features - found in EGCS 1.0.x releases. - - The EGCS 1.0.1 release includes installation instructions in both HTML - and plaintext forms (see the INSTALL directory in the toplevel - directory of the EGCS 1.0.1 distribution).

Also note that -Wall includes - -Wreturn-type, so if you use -Wall you will need to specify - -Wno-return-type to turn it off. - * Exception handling may not work with shared libraries, - particularly on alphas, hppas, and mips based platforms. Exception - handling is known to work on x86-linux platforms with shared - libraries. - * Some versions of the Linux kernel have bugs which prevent them - from being compiled or from running when compiled by EGCS. See the - FAQ (as shipped with EGCS 1.0) for additional information. - * In general, EGCS is more rigorous about rejecting invalid C++ code - or deprecated C++ constructs than G++ 2.7. As a result it may be - necessary to fix C++ code before it will compile with EGCS. - * G++ is also aggressively tracking the C++ standard; as a result - code which was previously valid (and thus accepted by other - compilers and older versions of G++) may no longer be accepted. - * EGCS 1.0 may not work with Red Hat Linux 5.0 on all targets. EGCS - 1.0.x and later releases should work with Red Hat Linux 5.0. - _________________________________________________________________ - - Please send FSF & GNU inquiries & questions to [1]gnu@gnu.org.
