Very short week (3 half days) == Progress == * GCC trunk cross-validation (2/10): - monitored results, and reported some regressions/new fails - moved away from Jenkins - as commit rate has decreased, there is no backlog in validations * Neon-intrinsics test (1/10): - Continuing conversion for inclusion in the GCC testsuite. - Preparing an additional Makefile, simpler than the current one, to help using the testsuite for various GCC variants until conversion is complete. == Next == * Continue to closely monitor GCC trunk validations * Neon intrinsics tests * Off Thursday/Friday

I have removed the "zlib" folder from "gcc-linaro-4.8-2014.03.tar.xz" tarball, the compiler is also using zlib-1.2.5 statically linked, and thats permit compile the Linaro toolchain.
