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 dynamically create README.txt: * The hard coded README.txt is removed. * Update build scripts to generate the README.txt, which depends on - README.texi, which is the common template for all TARGETS. - config.texi, which sets the default configuration for the TARGET. Each TARGET has a config.texi. - version.texi, created during build, includes GCC_VERSION, GDB_VERSION and TOOLCHAIN_VERSION. 4. Update Linaro GCC and GDB to 2012.12 in Linaro crosstool-ng, workaround gdb mingw32 link fail issue (due to mbsrtowcs is redefined in gdb/gnulib), finish the smoke test and spawn release builds.
Plans: * Investigate how branch cost impacts on code generation. * Release Linaro Toolchain Binaries 2012.12.
