[ACTIVITY] Week 32
== Issue == * None. == Progress == * Refine and send the patch to fix pr61225 in Combine pass for review (2/10). * Send out the ARM backend patch to keep some constant in register (TCWG-486, 2/10). * Rebase and test ccmp related patches (TCWG-488, 2/10). * R/M toolchain related work (4/10). == Plans == * Ping pending patches. == Planed leaves == * Aug. 18 - 26. ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] 4 - 8 August 2014
== Progress == TCWG-445 - AArch64 does not generate post-decrement stores. * Issue resolved with Jiong's prologue/epilogue patch committed to trunk. * Closed the card. TCWG-291 - Zero/sign extensions (5/10) * More review and posted patch based on that which was accepted * Ran full set of validation (including s390x, aarch64 be, x86 and arm) * Committed two outstanding patches * Closed the card. TCWG-413 - Release benchmarking (2/10) * Benchmarking or release for a15 and a57 TCWG-468: Sha1 regress (2/10) * Experimented with back-end patterns. Not much improvement for the test-case. - Misc (1/10) * Looked at gcc bugs and closed old ones. * Posted test-case patch. == Plan == - Sha1 regressions - Fixing assigned Bugs ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] 4 August - 8 August 2014
== Progress == * TCWG-180 Debugging - LTO bootstrap failure in Aarch64 with GCC 4.9. (6/10) Tried to recompile object files that showed differences in GCC trunk on amd64 machine.It turned out that GCC make system always builds LTO files in “gcc” directory and uses prev-gcc/xg++ to build them. No differences when building stage2 and stage3 objects under same directory “gcc” in FSF trunk. Doing the same experiment with gcc 4.9 branch shows failure both in x86_64 and aarch64. Communicated the issue to Richard Beiner. Got some feedback on debugging from Honza and Richard. Tried passing –save-temps to BOOT_CFLAGS using FSF trunk, getting assembler errors. Need to come back to this problem after finding root cause. Read about LTO passes and wpa (partitioned ) vs non portioned mode. * Others (2/10) * Upstream patch review. * 1-1 Meeting Christophe. * Misc and internal meeting. * setup LLVM. * Friday off (2/10). == Plan == * Continue LTO bootstrap issue. * Benchmark Core mark with LTO. * Upstream patch review. == MISC == * National holiday on 15th August . ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
RE: [ACTIVITY] 4 August - 8 August 2014
You should also look into https://gcc.gnu.org/bugzilla/show_bug.cgi?id=62077 which looks exactly the same issue as your LTO issue you are seeing. There is some debugging notes there too.

[ACTIVITY] Aug 4-10
== Progress == * Fixed aarch64_be-none-elf builds and cross tests. (2/10) * Forked ancient RSH support in DejaGnu to be more SSH aware. SSH is now takes 1/4 of the time it used to for each remote execution test case. (TCWG 512 - 4/10) * Stabilized new ZSSH protocol in DejaGnu, also much faster than the current RSH/SSH support. (TCWG 512 - 3/10) * Meetings and Misc. (1/10) == Plan == * Get my D01 board working finally, since I killed my Odroid U2. * Review benchmarking patches. * Do more thorough testing of SSH performance improvements. ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
