| * | Introduce new csu0 variant for -static -pie binaries to use called |   kurt | 2014-12-22 | 4 | -4/+315 | |
| | | | | | | | | | | | | | | | | | | | rcsu0.o where the initial 'r' is for relocatable. rcsu0.o performs self-relocation on static pie binaries by calling a slightly modified copy of ld.so's _dl_boot_bind() in boot.h. The first arch implementatation is also included for amd64 where __start calls _dl_boot_bind() and then calls ___start(). Includes parts from kettenis@ to help get R_X86_64_64 relocations working and proper handling for undefined weak symbols. This is the first part of several to get static pie self-relocating binaries working. binutils, gcc and kernel changes are forthcoming to complete the solution, then per-arch implementations are needed for MD_RCRT0_START in csu. okay kettenis@ pascal@ deraadt@ | |||||

| * | Increase _STACKALIGNBYTES to 15 (was 7), and make sure the stack is aligned |   miod | 2014-02-22 | 1 | -1/+3 | |
| | | | | | | | | to a 16 byte boundary in csu (similar to what the other arches where _STACKALIGNBYTES != _ALIGNBYTES do). This is necessary for long double variables on the stack to be correctly aligned. | |||||
| * | build crt*S with -fPIC instead of -fpic | miod | 2014-01-14 | 1 | -2/+2 | |

| * | Move atexit(3) into crtbegin.c and certbeginS.c such that we can pass the |   kettenis | 2013-12-28 | 4 | -4/+36 | |
| | | | | | | | | | | | right __dso_handle and have dlopen'ed shared objects run their atexit handlers when they get unloaded. This is what Linux does, and several ports depend on this behaviour (and will crash upon exit without this chang). Based on an earlier diff from matthew@ Tested by ajacoutot@ ok deraadt@ | |||||
| * | Add assembly code to set up the arguments for the common C startup code. This | kettenis | 2013-12-23 | 1 | -29/+19 | |
| | | | | | | | | means we no longer rely on how the C compiler sets up the initial stack frame and allows us to get rid of MD_NO_CLEANUP. ok deraadt@, guenther@ | |||||

| * | Fix static linking of libpthread: have crt0 invoke __init_tcb() if it's | guenther | 2013-12-12 | 2 | -2/+12 | |

| * | mips64 no longer uses scrt0.o, and it was identical to crt0.o anyway. | guenther | 2013-12-01 | 4 | -17/+5 | |

| * | The kernel and ld.so have passed 0 in r0 for use as the cleanup | guenther | 2013-11-10 | 1 | -11/+6 | |
| | | | | | | | | | | | 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@ | |||||
| * | The kernel and ld.so have passed 0 in r7 for use as the cleanup | guenther | 2013-11-10 | 1 | -19/+5 | |
| | | | | | | | | | | 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@ | |||||
| * | The kernel and ld.so pass 0 in %rdx for use as the cleanup callback | guenther | 2013-11-10 | 1 | -11/+6 | |
| | | | | | | | | | 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@ | |||||

| * | the fpu control symbol on sh (__fpscr_values) suddenly becomes local |   jsg | 2012-04-12 | 1 | -2/+5 | |
