Only assign the environ in the startup code when environ is NULL. Preloaded library could have changed the environment, and unconditional assingment to the environ undoes the customization. The binaries needs to be recompiled to get the fix.
Move the common code to set up environ and __progname into the helper. Note that ia64 possibly not fixed, due to it still using old csu.

Stop calling _init/_fini methods from crt1 for dynamic binaries. Do call preinit, init and fini arrays methods from crt1 for static binaries.
Mark new crt1 with FreeBSD-specific ELF note.
Move some common crt1 code into new MI file ignore_init.c, to reduce duplication. Also, conservatively adjust nearby sources for style.

Fixed profiling of main() for amd64 and i386. This started rotting in 1993 in rev.1.5 of the i386 a.out version (csu/i386/crt0.c). Profiling uses a magic label "eprol" to delimit the start of the part of the text section covered by profiling. This label must be placed before the call to main() to get main() properly profiled. It was placed there in rev.1.1 of crt0.c. Rev.1.5 imported the initial implementation of shared libraries in FreeBSD and misplaced the label. Fortunately, the misplaced label was misspelled and the old label wasn't removed, so the new label had no effect. Unfortunately, when profiling was implemented for the ELF in 1998 in rev.1.2 of csu/i386-elf/crt1.c, only the incorrectly placed label was copied (after fixing its name). The bug was then copied to all other arches. The label seems to be still misplaced in NetBSD for most arches. It is in common.c for most arches so it is even further from being inside the function that calls main().
I think "eprol" is short for "end of prologue", but it must be placed before the end of the prologue so that it covers main(). crt0.c has it before the calls atexit(_mcleanup) and monstartup(...), but it cannot affect these calls so I moved it after the call to monstartup(). It now also covers the call to _init() but not the newer call to _init_tls(). Profiling of _init() seems to be harmless, and the call to _init_tls() seems to be misplaced.

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).

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.

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).

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.

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.

* Bring back the guts of crt{i,n}.S. This allows C++ exceptions to work when using the egcs and gcc-devel ports, along with GCC built from stock public FSF sources. With out this change, FreeBSD will be removed from the list of systems GCC 3.0 must be evaluated on before release. With the effort some of us put into getting FreeBSD on this list, we should not turn this effort into a waste, else we might not be worth fighting for in the future. (note that Alpha and IA-64 versions of crt{i,n}.S are needed)
* Switch from our own crt{begin,in} to those created from GCC's crtstuff.c. This will allow us to switch to DWARF2 exceptions in the future, along with staying in sync with any future GCC requirements.
* Break out our ELF branding bits into a seperate file. Currently this is now included by our crt1.c files (since this functionality was part of our native crtbegin.c). Later crtbrand.o will be merged in the creation of crti.o.

Strip the leading path from __progname as is done in the a.out case. Also bring in stddef.h so we can use NULL instead of 0 for pointer comparisons.

Make profiling work for ELF. gprof now autodetects the format of the executable file, so it will work for both a.out and ELF format files. I have split the object format specific code into separate source files. It's cleaner than it was before, but it's still pretty crufty.
Don't cheat on your make world for this update. A lot of things have to be rebuilt for it to work, including the compiler and all of the profiled libraries.
