[ANNOUNCE] Linaro Binary Toolchain Release GCC 5.1 2015.08

[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-***@lists.linaro.org or file a bug at

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)
