== Progress == * Type promotion pass (6/10) - Fixed major false positive uninit warnings = Changed tree-ssa-uinit to handle SEXT_EXPR = preserving TREE_NO_WARNING set by SRA = Somemore fixes to preserve debug loc - There are still some more but this is mainly due to how tree-ssa-uinit is designed - Working through the output patterns; some are simple changes but some needs more analysis - Planning to create a branch with the latest version for easy review * Bugs (1/10) - PR70359 * Misc (1/10) - GCC Lists * Public holiday (2/10) == Plan == * Type promotion pass benchmarking * Perf with LTO

See the NEWS section below for details. Download release packages from: http://releases.linaro.org/components/toolchain/gcc-linaro/5.3-2016.02/ http://releases.linaro.org/components/toolchain/binaries/5.3-2016.02/ Previous snapshots and release-candidates are at: http://snapshots.linaro.org/components/toolchain/binaries/ Previous releases are at: http://releases.linaro.org/components/toolchain/binaries/ Host Requirements ================== Linaro officially supports the current and previous Ubuntu LTS releases (as of the time of this release). This does not mean that the toolchain will not work on other/older Linux distributions. See the following for the life-time of Ubuntu LTS releases. https://wiki.ubuntu.com/Releases The host system upon which the cross-compiler will run requires a minimum of glibc 2.14, because of API changes to glibc's memcpy API. https://bugs.linaro.org/show_bug.cgi?id=1869 Package Versions ================= Linaro GCC 5.3-2016.02 FSF glibc 2.21 (release/2.21) Linaro newlib 2.1.0-2014.09 (linaro_newlib-branch) Linaro binutils 2.25 (linaro_binutils-2_25-branch) FSF GDB 7.10 (gdb-7.10-branch) Linaro toolchain package git branches are hosted at: http://git.linaro.org/?a=project_list&s=toolchain%2F&btnS=Search NEWS for Linaro GCC 5.3-2016.02 ================================ * Applied fix for CVE-2015-7545 - A stack-based buffer overflow in glibc's getaddrinfo() was corrected in glibc 2.23 and backported into glibc 2.21. https://sourceware.org/ml/libc-alpha/2016-02/msg00416.html * ARMv8.1 Instruction Support - ARMv8.1 instructions support was checked into GCC and binutils.
