The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2015.01
engineering release of the Linaro GCC 4.9 source package.

4.9 series. It is based on FSF GCC 4.9.3-pre+svn219502 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. The Linaro TCWG provides
stable[1] quarterly releases and monthly engineering[2] releases.
Interesting changes in this GCC source package release include
