* Setup x86_64 ABI and add -mssse3 to x86 ABIPavel Chupin2014-06-201-1/+1
| | | | | | | | | | | 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.

* Extend MIPS GCC4.6/4.7/4.8 -mldc1-sdc1 to control ldxc1/sdxc1 tooIceberg Fu2013-08-302-3/+3
| | | | | | | | | | | | | -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.

* Add an internal switch -minline-thumb1-jumptable to ARM gcc4.6/4.7/4.8Lai Wei-Chih2013-08-024-3/+9
| | | | | | | | | | | | | | | | | | | | 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% Change-Id: I582898955b28e53e988a91bc1a64b76fba677e58

* Remove hardcoded -m32 in compiler optionsPavel Chupin2013-05-221-1/+1
| | | | | | | | | | | | | 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.

* Fix ARM/GCC-4.7,4.8 generates insufficient alignment for NEON vst/vldAndrew Hsieh2013-05-151-2/+6
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | In darwin where readelf isn't available, gcc/configure fails to set HAVE_LD_PERSONALITY_RELAXATION for MIPS, causes TARGET_WRITABLE_EH_FRAME=1 and flag_dwarf2_cfi_asm=0 (ie. disable CFI directive), and fails ld.mcld It's curious that the successful detection of the /tmp/ndk-$USER/gcc/binutils-2.21/readelf requires binutils to exist in the GCC's source tree, according to gcc/configure. Other tools (objdump, nm, ld, as, etc) can be successfully located because of OBJDUMP_FOR_TARGET, NM_FOR_TARGET, etc. Fix to look for READELF_FOR_TARGET in gcc/configure See https://android-review.googlesource.com/#/c/54760 https://android-review.googlesource.com/#/c/54770 https://android-review.googlesource.com/#/c/54710 Change-Id: I8b057a70d43389d3d9d02b5c54b8365ebe6487d1

* Support OpenMP+Bionic on ICS/GCC-4.7.2 for task parallelismGeunsik Lim2012-12-252-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
