of the Linaro GCC 4.9 source package. This is a respin of the 2014.07
release which
contained a backport of a revision that is only relevant to trunk.
Changes in this GCC source package release are:
* Updates to GCC 4.9.1 (svn212635)
* Revert backport of [AArch32] Fix PR target/61154.
Please find the original 2014.07 release notes below:
The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2014.07
stable release of the Linaro GCC 4.9 source package.
Linaro GCC 4.9 2014.07 is the fourth Linaro GCC source package release in the
4.9 series. It is based on FSF GCC 4.9.1+svn212419 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 stable[1] 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 engineering[2] releases.

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