The Arm GNU Toolchain for the A-profile Architecture
=====================================================
The Arm GNU Toolchain for the A-profile Architecture 8.2-2018.08 Release is now available.
Arm is pleased to announce the first Arm-built release of the pre-built GNU
cross-toolchain for the A-profile cores: GCC 8.2-2018.08. This is the same
toolchain that was previously built and distributed by Linaro.
For the official announcement, see:

News for GCC 8 (as of GCC 8.2-2018.08)
=======================================
* All GCC 8.2 features. For details on GCC 8 release series, please refer to
the list of changes, new features, and fixes.
* Linaro specific pre-processor macros to ensure that this is a continuation
from the Linaro releases.
* Spectre v1 mitigation backport from upstream FSF trunk include the revisions
listed below. This is an initial backport of those mitigations in the GNU
toolchain and should be regarded as support for prototyping and early access
only. Moreover, while the backports include support for the other
architectures, they are included for completeness and all issues regarding
these patches must be taken up upstream in the https://gcc.gnu.org/bugzilla by
reproducing the same with upstream FSF trunk. Arm is interested in feedback
regarding these workarounds for Spectre v1. A description of the mitigation has
been published on LWN.net.
