== Progress == * builtin_bswap16: * Backported missing patch from thunk to Linaro/4.7. One test still failing in the hard-float + thumb configuration because it forces armv6 and results in a unsupported configuration: vfp-1 + hard-float. Resumed discussion about a fix I proposed 3 weeks ago.

* PGO/hot-cold partitioning/Spec2k: * read doc about spec2k * started looking at 254.gap causing an ICE. * started studying qemu traces about 175.vpr crashing when compiled using profiling info. Cold code returns from a function using a clobbered lr value.

== Next == * builtin_bswap16: * complete backport to linaro-gcc 4.7.

* PGO/hot-cold partitioning/Spec2k: * investigate compiler crash and runtime failures.
