The Linaro Toolchain Working Group is pleased to announce the 2012.12
release of the Linaro Toolchain Binaries, a pre-built version of
Linaro GCC and Linaro GDB that runs on generic Linux or Windows and
targets the glibc Linaro Evaluation Build.
Uses include:
* Cross compiling ARM applications
Summary:
* Validate RM toolchain
* Prepare Linaro Toolchain Binaries 2012.12 release.
* Collect performance data for different branch cost.
Details:
1. Validate RM toolchain release.
2. Collect denbench and spec2000int performance data for branch cost tuning.
3. Fix README issue (lp:1068402) by
