32-bit: replace -msse3 by -mssse3
64-bit: setup default options as -msse4.2 -mpopcnt
Note: when multilib compiler is used -m32 will match 32-bit options and
-m64 or default (neither -m32 nor -m64) will match 64-bit options.

-mldc1-sdc1 now also controls codegen of ldxc1/sdxc1, the indexed
versions (where address of load/store is computed from sum of two
registers) of ldc1/sdc1 which are already controlled by this option.
Although double (or struct containing double) is always aligned
and the stock does guarantee 8-byte alignment, this option
is to workaround issue when double is allocated from a custom
allocator w/o honoring 8-byte minimal alignment.

Default is off (ie. no changes of behavior), meaning that gcc may
generate thumb1 jumptable helper calls (eg. __gnu_thumb1_case_sqi) for
switch/case.
Use -minline-thumb1-jumptable to compile code which can be linked
with compiler-rt where helper __gnu_thumb1_case_* doesn't exist.
This is mainly for use to compile NDK gabi++/stlport/libc++ to be
independent of libgcc.a. The only affected binaries are all
in armeabi. ABIs armeabi-v7a and x86/mips aren't affected. Size
differences are
libgabi++_static.a 176286 -> 176538 +0.1%
libstlport_static.a 1406346 -> 1413318 +0.5%
libc++_static.a 2426814 -> 2439074 +0.5%

It's required for x86_64 targets where we obviously don't want to
enforce -m32.
It shouldn't affect standard i686 targets because i686 is enforced on
configure stage and it effectively removes 64-bit support, keeping -m32
default.
Patch changes 4.7 and 4.8 only. x86_64 targets are not expected to be
supported in older gcc versions due to many issues and dependencies.

GCC allocates memory buffer and passes it as the first hidden argument
for function return large composite type (ie. > 4 bytes for all NDK
toolchain). Problem is that GCC doesn't observe the aligement
required by the type, and ARM EABI only requires stack to be aligned
to 8-byte.
Please see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57271 for external
bug tracking this issue and testcase. This CL offers temp relief before
formal one

This option is on by default for arch supports it, but can be turned
off by "-mno-ldc1-sdc1" to workaround issue, for example.

1. Fixed darwin build of GCC 4.8/X86 by removing trailing
',' from the last item of enum. Not discovered before
because GCC 4.8 now builds with -Wall -Werror, and gcc-4.2.1
in darwin is picky about that
2. Fixed -fuse-ld=mcld

ARM/X86 GCC in NDK explicitly emit -m armelf_linux_eabi and -m elf_i386,
respectively, for linker. Fix MIPS to do the same, to help mclinker
which is built vanilla and relies on either filename (eg.
eg. arm-linux-androideabi-ld.mcd implies arm) or -mtriple/-march/-m
to figure out the target

posix_memalign doesn't exist in NDK. Code inludes ?mmintrin.h
which in turn includes mm_malloc.h may fail to link
For AOSP platform build which uses the same compiler, add
-DHAVE_POSIX_MEMALIGN to restore the original behavior.
Other than non-zero return value which _mm_alloc already ignores, both
paths are functioanlly identical (under the hood dlmalloc.c in 32-bit
ensure alignment is at least 16-byte)

doesn't have (has pthread* in libc.so instead)
2. Because of 1., we can restore to the original order of

The patch supports OpenMP library to parallelize the existing
C/C++ code (e.g: for task parallelism) rapidly/easily without
any modification of android platform on multicore embedded devices.
The original patch is made by Keith Obenschain (using GCC 4.4.3).
. Archive - https://android-review.googlesource.com/#/c/34491/
I just moved GCC version from 4.4.3 to 4.7.2 for ktoolchain
version 2.5. The patch is good to me when I evaluate a lot of
C/C++ source code with OpenMP's #parama. we move the version
of OpenMP from version 2.5 to version 3.1.
Please, refer to the "kandroid toolchain" menu in www.kandroid.org
to compile source code including bionic and openmp library on real
Android devices.
http://kandroid.org/board/board.php?board=toolchain&command=body&no=16
I tested Openmp library with the latest GCC 4.7.2 on Android/ARM
devices as following. Please refer to the below example.
geunsik@rhel6$> ./arm-linux-androideabi-gcc openmptest.c -L
/usr/local/ktoolchain-cortexa9-ver2.5-20120515-bionic/arm-linux-androideabi/lib

To choose between "global" (default) and "tls" (new)
for -fstack-protector, -fstack-protector-all, and
-fstack-protector-strong (GCC 4.6+).
Note that this alone doesn't enable any -fstack-protector*
For NDK: The default "global" generates code backward
compatible with older bionic
For AOSP: build may add "-mstack-protector-guard=tls" to
build platform code with new bionic (*1)

After https://android-review.googlesource.com/#/c/45416 bionic provides
stack-protector random value per each thread at %gs:20. Therefore return
compiler back to %gs:20 code gen, same as for glibc.
