>From [1]: * All GCC 8.2 features. For details on GCC 8 release series. * 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. 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. See "Release Note": [1] https://developer.arm.com/open-source/gnu-toolchain/gnu-a/downloads# Tested with qemu_arm_vexpress_defconfig.

Arm toolchain for the ARM architecture. It uses GCC 8.2.1,
|
|
GDB 8.1.1, glibc 2.28, Binutils 2.30. It generates code that
|
|
runs on all Cortex-A profile devices, but tuned for the
|
|
Cortex-A9. The code generated uses the hard floating point
|
|
calling convention, and uses the VFPv3-D16 FPU instructions.
|
|
|
|
This is the same toolchain that was previously distributed by
|
|
Linaro.
