| 2013-12-03 | Merge the per-arch crt0.c files into common_elf/crt0.c, with MD macros in | Philip Guenther | |
| the md_init.h files. Worked out with and ok miod@; ok matthew@ | |||
| 2006-10-10 | Preliminary userland bits for OpenBSD/landisk, many things coming from | Miod Vallat | |
| NetBSD. | |||
| 2013-12-01 | mips64 no longer uses scrt0.o, and it was identical to crt0.o anyway. | Philip Guenther | |
| Delete unused #ifndef SCRT0 conditionals. ok miod@ | |||
| 2013-11-10 | The kernel and ld.so have passed 0 in r0 for use as the cleanup | Philip Guenther | |
| callback for about a year, so it's safe to make __start() pass that as the cleanup argument to ___start(), and have *that* conditionally pass it to atexit(). Eliminate the no-longer-used obj and ps_strings arguments to position things correctly, simplifying the ASM wrapper slightly. ok kettenis@ miod@; testing patrick@ | |||
| 2013-11-10 | The kernel and ld.so have passed 0 in r7 for use as the cleanup | Philip Guenther | |
| callback for about a year, so it's safe to make __start() treat that as the cleanup argument and conditionally pass it to atexit(). Eliminate the no-longer-used obj and ps_strings arguments to position things correctly, which lets us eliminate the ASM wrapper completely. ok kettenis@ miod@ | |||
| 2013-11-10 | The kernel and ld.so pass 0 in %rdx for use as the cleanup callback | Philip Guenther | |
| for about a year, so it's safe to add the test and atexit() call. While here, drop the no-longer-used obj and ps_strings and the asm to set those up, switch from sys/param.h to limits.h, and ANSIfy. ok kettenis@ | |||
| 2013-09-08 | Remove a.out leftovers. (it's september now) | Miod Vallat | |
| 2013-07-05 | VAX ELF userland bits. Consists mostly of register prefix additions. | Miod Vallat | |
| 2013-05-08 | Don't declare ___start static, for gcc4 would optimize it out. | Miod Vallat | |
| 2013-02-02 | Userland bits for m68k/ELF. Mostly addition of register prefixes to the | Miod Vallat | |
| assembler instructions, and cope with the few changes in return values location. | |||
| 2013-01-15 | build crt{begin,end}S.o with -fpic. | Miod Vallat | |
| 2013-01-05 | Switch m88k ports to ELF. | Miod Vallat | |
| 2012-12-31 | Spell `calculation' correctly. | Miod Vallat | |
| 2012-12-24 | Register cleanup handler passed by ld.so with atexit(3). | Mark Kettenis | |
| tested by benno@ | |||
| 2012-12-24 | Register cleanup handler passed by ld.so with atexit(3). Fix stack alignment. | Mark Kettenis | |
| ok guenther@ | |||
| 2012-12-23 | Register cleanup handler passed by ld.so with atexit(3). | Mark Kettenis | |
| 2012-12-23 | Explicitly align the stack on a 16-byte boundary such that constructors can | Mark Kettenis | |
| use SSE instructions. In principle we should be able to rely on the stack to be aligned properly, but the i386 calling convention makes this rather fragile. ok guenther@, deraadt@ | |||
| 2012-12-22 | Register cleanup handler passed by ld.so with atexit(3). | Mark Kettenis | |
| ok kurt@ | |||
| 2012-12-19 | crtbeginS.o needs to be built with -fPIC, otherwise bloated shared libraries | Mark Kettenis | |
| silently crash when running constructors. Tested by landry@. ok beck@ | |||
| 2012-12-05 | Remove excessive sys/cdefs.h inclusion | Theo de Raadt | |
| ok guenther millert kettenis | |||
| 2012-11-01 | Register cleanup handler passed by ld.so with atexit(3). | Mark Kettenis | |
| ok kurt@ | |||
| 2012-09-08 | Reverse the order that ctors and dtors are run in accordance with | Matthew Dempsky | |
| GCC's documentation. Fixes GNU C++'s init_priority attribute. ok miod | |||
| 2012-08-28 | Add __guard_local as a hidden symbol to ld.so, kernel, and every | Matthew Dempsky | |
| executable and DSO (via crtbegin.c/crtbeginS.c). Not used yet, but needed before GCC can start emitting -fstack-protector code that uses them instead of __guard. | |||
| 2012-08-22 | Convert cpp | as rules in bsd.lib.mk and lib/libc/sys/Makefile.inc to pure cc | Pascal Stumpf | |
| invocations. This allows us to use the compiler builtin define __PIC__ to check for PIC/PIEness rather than passing -DPIC. Simplifies PIE work a lot. ok matthew@, conceptually ok kurt@ | |||
| 2012-04-12 | the fpu control symbol on sh (__fpscr_values) suddenly becomes local | Jonathan Gray | |
| instead of global with gcc4 and this ends up breaking things in hard to debug ways. So move the definition to csu instead of libgcc. ok miod@ | |||
| 2011-11-08 | Pass install the -S option to avoid a window where the target isn't | Philip Guenthe | |
| executable (by mode or content), which can trip up builds with 'make -j' (The generic fix is in share/mk/*; some Makefiles have their own INSTALL lines) ok millert@ deraadt@ | |||
| 2011-09-19 | Use long calls like we do on hppa, otherwise the function we want to call | Mark Kettenis | |
| might be unreachable. | |||
| 2011-08-19 | Make sure the stack is properly aligned for using SSE instructions. While | Mark Kettenis | |
| our in-tree compiler will emit code to do this at the start of main(), other compilers might not do that. ok miod@ | |||
| 2011-07-09 | On hppa64 we need to use __gp instead of $global$. | Mark Kettenis | |
| 2011-07-04 | enter ia64 for obj | Theo de Raadt | |
| 2011-07-04 | Add csu ia64 support. | Paul Irofti | |
| 2011-04-20 | Implement correct prologue and epilogue for hppa64. | Joel Sing | |
| ok kettenis@ | |||
| 2011-03-31 | Make sure everything run from .init and .fini sections gets a properly aligned | Mark Kettenis | |
| stack. ok fgsch@ | |||
| 2011-03-30 | Make sure everything run from .init and .fini sections gets a properly aligned | Mark Kettenis | |
| stack. ok deraadt@, fgsch@ | |||
| 2010-12-24 | crtbeginS.o needs to be buit with -fPIC; with -fpic the relocations for the | Mark Kettenis | |
| gcc3/4 exception handling related symbols will be truncated causing linker failures when building shared libraries. ok drahn@, deraadt@, miod@ | |||
| 2010-09-12 | Since the stack layout changes from gcc3 to gcc4, change the inline asm to | Mark Kettenis | |
| deal with this. ok miod@ | |||
| 2010-05-01 | Sprinkle a few __used markers to prevent gcc4 from throwing away essential | Mark Kettenis | |
| bits of code and data. With this change gcc4 builds usable crt*.o on sparc64, other architectures probably need some more love. ok marco@, jsg@ | |||
| 2010-02-03 | Use MACHINE_CPU instead of MACHINE_ARCH to pick the correct machine dependent | Miod Vallat | |
| files or directories when applicable. The inspiration and name of MACHINE_CPU come from NetBSD, although the way to provide it to Makefiles is completely different. ok kettenis@ | |||
| 2009-12-10 | Make sure to use 64 bit instructions in the assembly statements (addi -> daddi) | Miod Vallat | |
| in the prologue; this gives a chance for binaries loaded with their stack over 2GB virtual, to run. Who's your daddi now? | |||
| 2009-10-28 | rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and | Theo de Raadt | |
| unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms | |||
| 2009-07-14 | Don't specify mode(SI) attribute for __EH_FRAME_END__ as we have | Jonathan Gray | |
| 32 bit ints on OpenBSD. ok kettenis@ | |||
| 2009-06-21 | fix rcs ids. ok sthen@ | Martynas Venckus | |
| 2009-06-16 | Do not break gcc -Z on powerpc. mprotect the got only if it is padded. | Dale Rahn | |
| Diff written and tweaked by kurt@ and myself. ok kurt@, now is agood time deraadt@ | |||
| 2009-04-13 | Add gcj java class registration hooks for gcc3 elf archs. From NetBSD | Kurt Miller | |
| with minor differences. okay kettenis@ drahn@ | |||
| 2009-03-06 | Work-around a gcc3 -g bug causing debug ld.so to crash. | Kurt Miller | |
| okay kettenis@ drahn@ | |||
| 2009-02-04 | Tag ELF shared libraries as OpenBSD. | Mark Kettenis | |
| ok kurt@, drahn@, miod@ | |||
| 2009-01-14 | Re-enable pie support on macppc (still off by default but usable | Kurt Miller | |
| again). Due to the way executable sections are loaded by the kernel, a one page .got section with the blrl instruction may be in the data cache and not flushed causing random crashes upon process startup. Flush the data cache before ___start() jumps there. Also mprotect the .got section to be read/exec instead of read/write/exec. ld.so knows how to cope and static binaries don't write to .got. written by and okay drahn@ | |||
| 2008-11-21 | revert -fpie for now, it produces crashing executables | Otto Moerbeek | |
| 2008-11-13 | fix rcs tag. | Jonathan Gray | |
| From patrick keshishian <sidster@boxsoft.com> | |||
| 2008-11-11 | Compile crt0.o, crtbegin.o and crtend.o with -fpie/-fPIE. This requires | Kurt Miller | |
| gcc with pie support to be built first. ok kettenis@ | |||
