[PATCH] Cortex Strings AArch64 optimized implementations of memmove, strlen and strncmp

by Marcus Shawcroft

Folks, This series of patches adds aarch64 specific implementations of memmove, strlen, strncmp to the cortex strings library and the corresponding test cases lifted directly from glibc. Enjoy /Marcus

libstdc++6 built from gcc-4.7 missing some symbols for arm-linux-gnueabi

by Matthias Klose

asking for some help about debian #697521 and lp: #1096619. looking at the config.log files for armel/armhf I don't see any differences. I assume it's a difference in the cpu configuration (armv4/v5 vs. armv7) not soft/hard-float. any pointers?

--no-gnu-unique option to disable STB_GNU_UNIQUE

by naveen yadav

Dear All, Is it possible to disable STB_GNU_UNIQUE(http://cygwin.com/ml/binutils/2011-10/msg00276.html) We need to rebuild the toolchain/ or is there any option at compile time to fix. Kind regards

== This Week == * Setting up laptop, desk, mailing lists, SSH keys, Launchpad, etc * Livermore Loops Benchmark * It fails on some types of builds but not others * Failure is due to LTO, problem identified, trying to get a reduced case * Getting LLVM building nightly and running the test-suite * Got where we are with ARM and others regarding buildbots * LLVM compiles and checks on pandaboard, need test-suite * Got a Chromebook to run the test-suite * LLVM web presence (pages, svn repositories, etc) dead == Next Week == * Reduce the LTO bug on Livermore kernels * Report it once I have more information and a reduced case * Try to fix it * Checkout Zorg (LLVM's build system integrator) * Force builds to use LNT (new test harness, which passes) * Someone else is looking into setting up consistent LTO tests to the rest already * Get Ubuntu on Chromebook and build LLVM on it + test-suite * Understand the CBuild infrastructure and setup a board to do it automatically * Revise the current LLVM build to be continuous and check-all * Help Nadav Rotem (Apple) with the cost model for vectorization on ARM VFP/NEON * Meeting with ARM and "le French" to finalize the EuroLLVM 2013 and send the CFP == Future == * Validate vectorization for ARM after cost model is reasonably accurate * Vectorization will be turned on by default as of 3.3 on -O2 or higher * Reduced strength with -Os, but still on * Make Livermore Loops vectorize * Allow vectorization to detect global structures as safe * Allow floating point vectorization if using -unsafe-math * Plan a workflow to report / fix bugs that our internal CBuild finds on ARM * Liaise with ARM on what processes can be shared / commoned-up * Try to be less verbose on activity reports...

int64_t definition conflict on Aarch64

by Riku Voipio

Hi, The following code fails to build with OE Aarch64 toolchain with current kernel headers. While ugly, the code is a reduced testcase from fuse build failure ( https://bugs.launchpad.net/linaro-oe/+bug/1087757 ) and the same fuse code compiles on all other architectures. Before I send a workaround for upstream, I'd like to know how we can end up with different definitions for int64_t when that happens on no other architectures - something wrong with the generic kernel headers? Testcase: #include <sys/types.h> #define __s64 int64_t #include <signal.h> int main(int argc, char **argv) { int64_t x=4; return x; } Failure: /data/oe/build/tmp-eglibc/sysroots/x86_64-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-gcc -save-temps --sysroot=/data/oe/build/tmp-eglibc/sysroots/genericarmv8 -o test test.c In file included from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm-generic/types.h:7:0, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm/types.h:1, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/linux/types.h:4, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm/sigcontext.h:19, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/bits/sigcontext.h:27, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/signal.h:338, from test.c:4: /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm-generic/int-ll64.h:29:44: error: conflicting types for 'int64_t' In file included from test.c:2:0: /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/sys/types.h:197:13: note: previous declaration of 'int64_t' was here

[Activity] Week 52

by Zhenqiang Chen

Summary: * Follow-up shrink-up and branch cost related work. * Investigate "MSR FPEXC, r2" assemble fail issues. Details: 1. RM toolchain related work. 2. Investigate "MSR FPEXC, r2" assemble fail issues. * According to Reference Manual, should use VMSR/VMRS to access FPEXC register other than MSR/MRS. * Binutils 2.23.1 or later had enhanced VMRS/VMSR to accept FPEXC register. 3. Rebase and test the shrink-wrap patches. 4. Read codes about impact of branch-cost. Plan: * Follow up the shrink-wrap and branch cost related work. Planed leaves: * Jan. 1-3, 2013 Best Regards! -Zhenqiang
