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.
Best regards!
