The Linaro Toolchain Working Group (TCWG) announces the 2014.06-1 release of the Linaro GCC 4.9 source package. This is a respin of the 2014.06 release which fixes some issues on AArch64 big-endian and in AArch64 libjava.

Changes in this GCC source package release include:

  • Updates to GCC 4.9.1-pre+svn211964
  • Revert backport of [AArch64] Define TARGET_FLAGS_REGNUM.
  • Backport of [AArch64] Cost model improvements.

Please find the original 2014.06 release notes below:

The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2014.06 stable release of the Linaro GCC 4.9 source package.

Linaro GCC 4.9 2014.06 is the third Linaro GCC source package release in the 4.9 series. It is based on FSF GCC 4.9.1-pre+svn211054 and includes performance improvements and bug fixes.

With the imminent release of ARMv8 hardware and the recent release of the GCC 4.9 compiler the Linaro TCWG will be focusing on stabilization and performance of the compiler as the FSF GCC compiler approaches version 4.9.1. The Linaro TCWG will provide monthly stable1 source package releases until FSF GCC 4.9.1 is released. At that point Linaro GCC 4.9 will merge in FSF GCC 4.9.1 and, release Linaro GCC 4.9.1, and then return to a schedule of stable quarterly releases and monthly engineering2 releases.

Interesting changes in this GCC source package release include:

  • Updates to GCC 4.9.1-pre+svn211054
  • Backport of [AArch32] PR rtl-optimization/60663

1Stable source package releases are defined as releases where the full Linaro Toolchain validation plan is executed.

2Engineering source package releases are defined as releases where the compiler is only put through unit-testing and full validation is not performed.
