[ANNOUNCE] Linaro Binary Toolchain Release GCC 5.1 2015.08

by Ryan Arnold

The Linaro Toolchain Working Group is pleased to announce the availability of the Linaro Stable Binary Toolchain GCC 5.1-2015.08 Archives. http://releases.linaro.org/components/toolchain/binaries/5.1-2015.08/ These archives provide cross-toolchain executables (compiler, debugger, linker, etc.) and shared libraries (libstdc++, libc, etc.) that target ARM or Aarch64 GNU/Linux and bare-metal environments. The cross-toolchain binaries execute on a Linux or MS Windows (under mingw32) host operating-system. For bugs related to this release please email linaro-toolchain(a)lists.linaro.org or file a bug at https://bugs.linaro.org/enter_bug.cgi?product=Linux%20Binary%20toolchain NEWS * 2015.08 * The Linaro GCC 5.1 2015.08 binary toolchain release is based on the Linaro GCC-5.1-2015.08 source archive release <http://releases.linaro.org/components/toolchain/gcc-linaro/5.1-2015.08/>. The major changes contained in 2015.08 over 2015.05 are described in the sections below on 2015.08-rc1 and 2015.08-rc2 . * 2015.08-rc2 * The Linaro 2015.08-rc2 release-candidate binary toolchain is based on the Linaro GCC-5.1-2015.08-rc1 release-candidate source archive. The only changes between 2015.08-rc1 and 2015.08-rc2 were the following changes in how the binary toolchains were built. The compiler itself was not changed. * x86_64 hosted, armv8l-linux-gnueabihf targetted cross toolchains are now correctly configured. This was broken in 2015.08-rc1. The cross-compiler targetting armv8l-linux-gnueabihf is now correctly configured with --with-arch=armv8-a --with-fpu=neon-fp-armv8 --with-float=hard --disable-multilib --enable-multiarch. * Glibc’s slibdir and libdir were once again modified to address Linaro Bugzilla 1717 – Linaro-4.9-2015.05 moved system libs from /libc/lib/ to /libc/usr/lib/ which breaks things. The following are now the correct locations: libdir=lib/ (linker-scripts and static archives) slibdir=usr/lib/ (shared objects) rtlddir=lib/ (dynamic linker) * 2015.08-rc1 * x86_64 hosted, armv8l-linux-gnueabihf targetted cross toolchain now provided. Delivering on REQ-477 – Enable x86_64 to Aarch32 (32-bit ARMv8-A) cross binary toolchain product release and CARD-1637 – Enable Aarch32 (32-bit ARMv8-A) cross binary toolchain product releases , armv8l-linux-gnueabihf targetted toolchains are now available as part of this release-candidate. * Python support in GDB for both Linux and Mingw32 (32-bit windows). Delivered as requested in the linaro-toolchain mailing list post title – windows binary builds with gdb-python enabled?. * Added missing expat support to GDB. This addresses the following linaro-toolchain mailing list post – "Missing expat support in GDB 7.8 multi-lib enablement for arm bare-metal targets." * A fix for multilib enablement in baremetal toolchains (as described in ABE Review 6862). * Library Paths are now congruent with older Linaro Toolchain path layouts. This addresses Linaro Bugzilla 1717 – Linaro-4.9-2015.05 moved system libs from /libc/lib/ to /libc/usr/lib/ which breaks things. libdir=lib/ (shared objects) slibdir=usr/lib/ (static libraries) rtlddir=lib/ (dynamic linker) -- Ryan S.
