Debuging shows segfaults while expanding THREAD_GSCOPE_WAIT. My assumption is thread pointer points to TCB and after allocating 16 Bytes before that, we can set pointer gaurd at tp -16. But not sure, why it affects the pthread structure header which holds gscope_flag. Also looked at TLS_MULTIPLE_THREADS_IN_TCB, enabling it lead to __libc_multiple_threads undefined errors. == Plan == * Continue libssp support. * PGO for aarch64

[ANNOUNCE] Linaro GCC 4.8 and 4.7 2013.10 released

by Christophe Lyon

The Linaro Toolchain Working Group is pleased to announce the release of both Linaro GCC 4.8 and Linaro GCC 4.7. Linaro GCC 4.7 2013.10 is the nineteenth release in the 4.7 series. Based off the latest GCC 4.7.4+svn203509 release, this is the sixth release after entering maintenance. Interesting changes include: * Updates to GCC 4.7.4+svn203509 * Fix for LP #1229170 Linaro GCC 4.8 2013.10 is the seventh release in the 4.8 series. Based off the latest GCC 4.8.1+svn203510 release, it includes performance improvements and bug fixes. Interesting changes include: * Updates to GCC 4.8.1+svn203510 * Improved AArch64 support (CRC extension, improved intrinsics, gprof support) * Improved Aarch32 support (bug fixes, better code generation, improved multilib) * Backports for bug fixes (PR58578 We are aware that FSF GCC 4.8.2 was released earlier this week. However, this release happened too late in our cycle for us to use it as the basis for Linaro GCC 4.8 2013.10. The only functional difference contained in FSF GCC 4.8.2 that is not in Linaro GCC 4.8 2013.10 is a correction to a x86 test case. The source tarballs are available from: https://launchpad.net/gcc-linaro/+milestone/4.7-2013.10 https://launchpad.net/gcc-linaro/+milestone/4.8-2013.10 Downloads are available from the Linaro GCC page on Launchpad: https://launchpad.net/gcc-linaro More information on the features and issues are available from the release pages: https://launchpad.net/gcc-linaro/4.7/4.7-2013.10 https://launchpad.net/gcc-linaro/4.8/4.8-2013.10 Mailing list: http://lists.linaro.org/mailman/listinfo/linaro-toolchain Bugs: https://bugs.launchpad.net/gcc-linaro/ Questions? https://ask.linaro.org/ Interested in commercial support?

== Issue == * AArch64 frame grows downward: no feedback yet. == Progress == * Disable-peeling: Vectorizer cost model has been changed upstream, quick look at benchmark results show little difference between before and after the change. Need to analyze further, since I expected the regressions previously identified with my patch to appear here too. * AArch64 bootstrap failure: succesfully bootstrapped in the model. * GCC trunk validation: - improved configurability (default cpu, fpu, mode, testsuite flags are selectable) - requested feedback to build the list of desirable combinations to validate * Backports/release 2013.10 - a few more backports completed - re-trying to backport the ILP32 and refactoring series proves again to be tricky, but helped identify backports which had escaped from the list. - cbuild has disk full again * GCC Neon intrinsics testsuite: -- posted a proposition to add my executable tests to the existing framework. No feedback yet. == Next == * Make 2013.10 releases, both with the historical process and using cbuildv2, in parallel * Disable-peeling/new vectorizer cost model: analyze bench results
