63f3798125 Add support for o32 (when it isn't the default), n32, n64, and o64 to
the linker spec.  Provide the ability to have a default ABI that's
different than o32 (again, for all 4).

c09ba32715 Properly support -fPIE by linking PIE binaries with specially-built
Scrt1.o instead of crt1.o, since the later is built as non-PIC.

Separate i386-elf crt1.c into the pure assembler part and C code,
supplying all data extracted by assembler stub as explicit parameters [1].
Hide and localize _start1 symbol used as an interface between asm and
C code.

22239c9dc4 Change gcc to assume a default machine architecture of 486 instead of 386
on "i386".  Doing it in the compiler is deemed to be less fragile then
attempting to provide a default -march setting via bsd.cpu.mk.  FreeBSD
itself has not supported plain 386 CPUs since 5.x.

f667763060 Output DWARF debug information for global 'using' declarations, instead
of just blowing up. A very similar change to this exists which is
GPLv3 licensed, this is my own change.

This problem was triggered by running the Boost regression tests.

2286fe7635 Second attempt at eliminating .text relocations in shared libraries
compiled with stack protector.

Use libssp_nonshared library to pull __stack_chk_fail_local symbol into
each library that needs it instead of pulling it from libc. GCC
generates local calls to this function which result in absolute
relocations put into position-independent code segment, making dynamic
loader do extra work every time given shared library is being relocated
and making affected text pages non-shareable.

e4c3a7fc88 Merge an important change that I mistakenly left out when merging C99
inline function support. This should fix instances where gcc
spuriously reports the following error:

    error: nested function 'foo' declared but never defined

d5ed956300 Make gcc use C99 inline semantics in c99 and gnu99 mode. This was the
original intent, but the functionality wasn't implemented until after
gcc 4.2 was released. However, if you compiled a program that would
behave differently before and after this change, gcc 4.2 would have
warned you; hence, everything currently in the base system is
unaffected by this change.  This patch also adds additional warnings
about certain inline function-related bogosity, e.g., using a
static non-const local variable in an inline function.

These changes were merged from a snapshot of gcc mainline from March
2007, prior to the GPLv3 switch. I then ran the regression test suite
from a more recent gcc snapshot and fixed the important bugs it found.
I also squelched the following warning unless -pedantic is specified:

    foo is static but used in inline function bar which is not static

This is consistent with LLVM's behavior, but not consistent with gcc 4.3.

7a5b5fae94 Make -fno-math-errno the default. Our libm doesn't support the SysV
mistake of setting errno, and never has.  This will need to be fixed
upstream in a more generic way, but the changes are somewhat more
involved.

1b93600c85 Make -mfancy-math-387 the default on FreeBSD, as it is on most other
operating systems. Previously, gcc would inhibit the generation of
fsqrt, fsin, and several other floating point instructions, for the
benefit of the old in-kernel math emulator, which was removed over 5
years ago.

7125e147b2 * gthr-posix.h (__gthread_active_p): Use the Solaris implementation
for FreeBSD as well.

This is the fix for __gthread_active_p() returning false positives
which was committed as rev. 1.1.1.8.2.1 to RELENG_7 but now looped
back to the vendor branch via the GCC repository and relicensed to
be GPLv2 by me.
Thanks go to gerald@ for getting the fix approved upstream and for
committing to the GCC repository.

11e27303d3 Fixed -mprofiler-epilogue. The garbage collector apparently doesn't
understand that non-local variables can never be collected, and when
it collected the static variable for mexitcount_libfunc, gcc aborted
on the next use of this variable.

This quick fix is to reinitialize the variable on every use and depend
on garbage collection recovering the small amount of memory wasted by
this, and not worry by the small amount of time wasted by this.  It
would be better to initialize the variable together with most of the
other libfuncs in optabs.c and depend on whatever magic is there to
prevent its collection, but we initialize it here to avoid taking at
least 2 more files off the vendor branch.
