* 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.

* 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.

| | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | 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

This patch helps that OpenMP recognizes the actual CPUs correctly for the task parallelism. Recent mobile devices dynamically disable or enable CPU cores on demand to optimize battery life. This impacts the output of '/proc/cpuinfo' (which only reports active ones). This patch provides a way to compute the total number of cores by parsing the content of '/sys/devices/system/cpu/' instead. Actual CPUs: total installed CPUs Online's CPUs: CPUs of the turn-on status Offline's CPUs: CPUs of the turn-off status Therefore, We need to enhance the existing approach using procfs like '/proc/cpuinfo/' or '/proc/stat'. This patch is suitable for Linux kernel. This patch is based on GCC 4.7.2. .RELATED LINKS: https://android-review.googlesource.com/#/c/52821/ https://android-review.googlesource.com/#/c/51950/ https://android-review.googlesource.com/#/c/51370/ https://android.googlesource.com/toolchain/gcc/ .UNIT TEST int main (int argc, char *argv[]) { int nthreads, tid; printf("SC_NPROCESSORS_ONLN: %d\n", sysconf (_SC_NPROCESSORS_ONLN)); /* Fork a team of threads giving them their own copies of variables */ { /* Obtain thread number */ tid = omp_get_thread_num(); printf("Hello World from thread = %d\n", tid); /* Only master thread does this */ if (tid == 0) { nthreads = omp_get_num_threads(); printf("Number of threads = %d\n", nthreads); } } /* All threads join master thread and disband */ } .LIMITATION OF SCOPE These functions have to be included in Bionic C library as the resource of sysconf().

| | | | | | | | | | | | | | | | | | | | 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 Change-Id: I236786d0e90a3152225de1eea5e73e3de4ac3f84

* | Use memalign instead of posix_memalign in GCC x86 mm_malloc.hAndrew Hsieh2013-02-201-0/+6
|/ | | | | | | | | | | | | | 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) Change-Id: I55e9bb8b80e1b55baa9744920df10fcf83218300

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.
