MFC r260874:

gcc: fix libgcc by adding the bswap builtins for all platforms.

This change was missing from r258428 which attempted to add the
bswap builtins to gcc. The change is also missing from the patch
in gnu/155309.

Fix this build for clang.

MFC r259730:

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.

MFC r259913:

For libstand and sys/boot, split off gcc-only flags into CFLAGS.gcc.

MFC r259927:

Fix pc98 build, by also forcing COMPILER_TYPE in sys/boot/pc98/boot2's
Makefile.

Enable libcompiler-rt on MIPS.

2013-04-20T14:44:28+00:00

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  on all our architectures.

Link libgcc_s against compiler-rt on ARM EABI. This allows us to use all of

2013-03-17T01:03:41+00:00

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.

Add compiler support for the ARM EABI.

2013-01-17T05:56:28+00:00

ARM EABI support is disabled by default and can be enabled by setting
WITH_ARM_EABI when building, however only the kernel-toolchain target will
work with this flag until the rest of the support is added.

Get libcompiler-rt and libgcc building on ARM with clang.

2012-12-18T07:26:55+00:00

* Don't provide clear_cache or the __sync_* functions on ARM with clang as
  they are provided by clang as builtin functions.
* Tell clang it is aloud to compile some libgcc code using heinous GCC
  extensions.

Clean up hardcoded ar(1) flags in the tree to use the global ARFLAGS in

share/mk/sys.mk instead.

This is part of a medium term project to permit deterministic builds of
FreeBSD.

we also have usable div/mod optimizations like libgcc has.
