37656b872b Replace LIBGCC by LIBCOMPILER_RT.
We now use libcompiler_rt on all platforms now. Instead of referring
directly to -lgcc and LIBGCC, use -lcompiler_rt and LIBCOMPILER_RT.

5ed2724da0 For ia64, add _bswapsi2 & _bswapdi2. The audio/flac port uses the
bswap32 builtin and the compiler emits a call to the libgcc function
rather than generating inline code.

b294993d63 To avoid having to explicitly test COMPILER_TYPE for setting
clang-specific or gcc-specific flags, introduce the following new
variables for use in Makefiles:

CFLAGS.clang
CFLAGS.gcc
CXXFLAGS.clang
CXXFLAGS.gcc

In bsd.sys.mk, these get appended to the regular CFLAGS or CXXFLAGS for
the right compiler.

108b6de211 Enable libcompiler-rt on MIPS.
Originally we disabled libcompiler-rt on MIPS and SPARC64, because of an
issue where __clzdi2 and __ctzdi2 would cause endless recursion. This
bug has been fixed in r230021 already, but for some reason we only
switched to libcompiler-rt on SPARC64 -- not MIPS.

This means we can finally use <stdatomic.h> on all our architectures.

b3a9841934 Link libgcc_s against compiler-rt on ARM EABI. This allows us to use all of
the symbols in compiler-rt, including the ones not available in the old
libgcc. This fixes the build with clang which generates calls to funstions
that are missing from libgcc_s.

1992e9a10c Add compiler support for the ARM EABI.

84db023ec1 Assume a big-endian default on MIPS and drop the "eb" suffix from MACHINE_ARCH.
This makes our naming scheme more closely match other systems and the
expectations of much third-party software.  MIPS builds which are little-endian
should require and exhibit no changes.  Big-endian TARGET_ARCHes must be
changed:
	From:		To:
	mipseb		mips
	mipsn32eb	mipsn32
	mips64eb	mips64

An entry has been added to UPDATING and some foot-shooting protection (complete
with warnings which should become errors in the near future) to the top-level
base system Makefile.

cd2ae2532f Retire TARGET_ABI.
Implement MACHINE_ARCH=mips64e[lb] to build N64 images.  This replaces
MACHINE_ARCH=mipse[lb] TARGET_ABI=n64.

MACHINE_ARCH=mipsn32e[lb] has been added, but currently requires
WITHOUT_CDDL due to atomic issues in libzfs.  I've not investigated
this much, but implemented this to preserve as much of the TARGET_ABI
functionality that I could.  Since its presence doesn't affect the
working cases, I've kept it in for now.

Added mips64e[lb] to make universe, so more kernels build.

And I think this (finally) closes the curtain on the tbemd tree.

hosing all sparc64 boxes out there, fall back to libgcc to prevent more

39cd938c39 Replace libgcc.a by libcompiler_rt.a.
libcompiler_rt.a is a BSD licensed C language runtime, which implements
many routines which are linked into binaries on architectures where
certain functionality is missing (e.g. 64 bits mul/div on i386).

Unfortunately, libcompiler_rt cannot replace libgcc entirely. Certain
features, such as an unwinder for exception handling, are missing.
That's why only libgcc.a is replaced for now, because this one does seem
to be complete.

Tested by:	rene (amd64), nwhitehorn (powerpc), droso (i386 exprun)
		and many others. Thanks!

e8dce5b9b3 Complete the integration of tbemd branch into head.
TARGET_BIG_ENDIAN is now completely dead, except where it was
originally supposed to be used (internally in the toolchain building).

TARGET_ARCH has changed in three cases:
(1) Little endian mips has changed to mipsel.
(2) Big endian mips has changed to mipseb.
(3) Big endian arm has changed to armeb.

Some additional changes are needed to make 'make universe' work on arm
and mips after this change, so those are commented out for now.

UPDATING information will be forthcoming.  Any remaining rough edges
will be hammered out in -current.

5619a3e4bf Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.
o) Add TARGET_ABI to the MIPS toolchain build process.  This sets the default
   ABI to one of o32, n32 or n64.  If it is not set, o32 is assumed as that is
   the current default.
o) Set the default GCC cpu type to any specified TARGET_CPUTYPE.  This is
   necessary to have a working "cc" if e.g. mips64 is specified, as binutils
   will refuse to link objects using different ISAs in some cases.
o) Add support for n32 and n64 ABIs to binutils and GCC.
o) Add additional required libgcc2 stubs for n32 and n64.
o) Add support for the "mips64r2" architecture to GCC.  Add the "octeon"
o) When static linking, wrap default libraries in --start-group and
   --end-group.  This is required for static linking to work on n64 with the
   interdependencies between libraries there.  This is what other OSes that
   support n64 seem to do, as well.
o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the
   former being what libgcc, etc., check and the latter seemingly being a
   misspelling of a hand merge from a Linux spec.
o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default
   ISA from the ABI.  Our old defaults were too liberal and assumed that 64-bit
   ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to
   the MIPS32 ISA, when we are supporting or will support some systems based on
   earlier 32-bit and 64-bit ISAs, most notably MIPS-III.
o) Merge a new opcode file (and support code) from a later version of binutils
   and add flags and code necessary to support Octeon-specific instructions.
   This should also make merging opcodes for other modern architectures easier.

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.

afb57df680 Update bmake glue to build GCC 4.2.
Also:
        Switch FreeBSD to use libgcc_s.so.1.

        Use dl_iterate_phdr to locate shared objects' exception frame
        info instead of depending on older register_frame_info machinery.
        This allows us to avoid depending on libgcc_s.so.1 in binaries
        that do not use exception handling directly. As an additional
        benefit it breaks circular libc <=> libgcc_s.so.1 dependency too.

        Build newly added libgomp.so.1 library, the runtime support
        bits for OpenMP.

        Build LGPLed libssp library. Our libc provides our own
        BSD-licensed SSP callbacks implementation, so this library
        is only built to benefit applications that have hadcoded
        knowledge of libssp.so and libssp_nonshared.a. When linked
        in from command line, these libraries override libc
        implementation.
