| | | | | | | | | | | | | | | | | | | | | | | section alignnment of 16 bytes for amd64 and this breaks file(1). Before: ./cp: ELF 64-bit LSB executable, AMD x86-64, version 1 (FreeBSD), for \ FreeBSD 127.7.9, statically linked, stripped after: ^^^^^^^ ./ls: ELF 64-bit LSB executable, AMD x86-64, version 1 (FreeBSD), for \ FreeBSD 5.0.1, dynamically linked (uses shared libs), stripped The reason for this is that the NOTE sections are not contiguous internally. If the note section has an alignment of 16, then anything that looks for the data is supposed to round up the payload start to the next multiple of the alignment. But FreeBSD/amd64 broke because the structure is declared as a single structure, not a (header,payload) group, where the payload had an explicit alignment roundup. The alternative is to change things like file(1) to ignore the ELF payload alignment rules for the PT_NOTE section only for FreeBSD. Notes: svn path=/head/; revision=121160

* _start() needed to be written in assembly. See crt1.S.Marcel Moolenaar2003-07-141-124/+0

* Rewite _start(). We cannot use a C function due to the fact that weMarcel Moolenaar2003-07-132-2/+193
| | | | | | | | | | | | | | | | | | | | don't call it according to the runtime specification and especially WRT to gp this can cause trouble. The gcc 3.3.1 import broke the ia64 runtime because the compiler saved gp prior to us being able to set it properly. Restoring gp after the calls would then invalidate gp and cause segmentation faults later on. By rewriting _start() as an assembly function, we also avoided even more gcc dependences, by trying to use gcc specific features to work around the problem. This version of _start() does not reference _DYNAMIC. We register the cleanup function when it's a non-NULL pointer. The kernel will always pass a NULL pointer and dynamic linkers may pass a non-NULL pointer. The machine independent code to set __progname now unfortunately is written in assembly. So be it.

* Removed garbage:Bruce Evans2003-06-041-3/+1
| | | | | | | | | | - -elf in CFLAGS had no effect except to reduce portability. - -elf in LDFLAGS had even less effect, since LDFLAGS is not used. - -Wall in CFLAGS had no effect except to reduce portability and break overriding of WARNS, since the setting of WARNS implies -Wall.

* Backed out previous commit (alignment suitable for RELENG_4) as plannedBruce Evans2002-12-012-66/+0
| | | | | | | | | | | since it has been MFC'ed. See the log message for the previous commit for more details. The alignment bug in gcc-3 has not been fixed, but it is not very serious and the previous commit just moved it (as intended). Approved by: re (murray) Notes: svn path=/head/; revision=107460
* Align the stack suitably for the version of gcc in FreeBSD-4 (providedBruce Evans2002-09-292-0/+66
| | | | | | | | | | | | | | | | | | | | | | -fomit-frame-pointer is not used). This is mostly moot for -current because gcc-3 does the alignment (slightly incorrectly) in main(). This patch is intended for easy MFC'ing and should be backed out in -current soon since it causes compiler warnings and better fixes are possible in -current. The best fix is to do nothing here and wait for gcc to do stack alignment right. gcc-3 aligns the stack in main(), but does it too late for main()'s local variables and too late for anything called before main(). A misaligned stack is now more than an efficiency problem, since some SSE instructions in some or all (hardware) implementations trap on misaligned operands even if alignment checking is not enabled.

* The main reason for this is to reduce diffs between all the crt1.c's.Mark Murray2002-07-166-91/+140
| | | | | | | | | | | | | | | | | | | | | | Assembler macros are tidied up and made as similar as sanely possible. The macros are translated into C (__inline static) functions for lint. Declaration orders are made the same. Declarations are all ISOfied and tidied up. Comment contents have gratuitous diffs removed. The net result is a bunch of crt1.c's that are 90% the same. It may be possible to now encapsulate the differences in one MD header, and have only one MI crt1.c file (although the macros to do this may be ugly).

| | | | | | | | | | | | | | | | except to generate spurious warnings about a system header <sys/param.h> having some inline functions (the bswap family). This backs out the main part of rev.1.5 (which was the only part left). The problem fixed by rev.1.5 of the Makefile went away in rev.1.5 of ../common/crtbegin.c when the references to do_ctors() and do_dtors() in the latter were moved from inline asm to C code. This leaves the problem that implementation details cause warnings. Discussed with: jdp Notes: svn path=/head/; revision=95721
