493b9af445 _start() needed to be written in assembly. See crt1.S. 2003-07-14 03:05:42 +00:00

2d0c7abf95 Rewite _start(). We cannot use a C function due to the fact that we
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.

8ba6f05132 Removed garbage:
- -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.

665ad725f7 Update for AMD64. repocopied from i386-elf/crt1.c. Deal with regparm
argument passing rather than stack based args.  The kernel passes the
base of the argument/env vector in %rdi (arg1).

26450b90d3 Remove the get_term() function. It pretty much can't work for
FreeBSD, and makes ugly diffs with the other crt1.c's. Leave
behind a comment (words supplied by Thomas Moestl) that explain
the issue.

1bae0a9e0c Backed out previous commit (alignment suitable for RELENG_4) as planned
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).

61d4be4f4d Align the stack suitably for the version of gcc in FreeBSD-4 (provided
-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.

bedd05ccec The main reason for this is to reduce diffs between all the crt1.c's.
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).

38e70a1e48 Whitespace diffs only; this brings this file into the same whitespace
convention as src/lib/csu/*/crt1.c.

This will make the follow up diffs easier to see and extract.

dc9ee40833 Major cleanup of bsd.lib.mk.
Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB.
INTERNALLIB now means to build static library only and don't install
anything.  Added a NOINSTALLLIB knob for libpam/modules.  To not
build any library at all, just do not set LIB.

0dd30d20d3 Removed "-fkeep-inline-functions" from CFLAGS, since it now has no effect
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.

76fe441a7b Do not use __progname directly (except in [gs]etprogname(3)).
Also, make an internal _getprogname() that is used only inside
libc. For libc, getprogname(3) is a weak symbol in case a
function of the same name is defined in userland.
