== Linaro and upstream GCC == * Linaro launchpad issues: - LP #672833, x64-64 varargs regression: after testing pushed bzr branch for merging. - LP #634738, inefficient low bit extraction: some discussion with Yao. - LP #618684, ICE when building ziproxy: looked into and quickly found not reproducible anymore of Linaro 4.5 trunk.
* Worked on some GCC bugzilla PRs: - PR44557, ICE in Thumb-1 secondary reload: this should be fixed by a change of the scratch operand constraint of "reload_inhi" from "r" to "l". Interesting to note that this was from the merged-arm-thumb-backend-branch merge, from about 10 years ago. - PR46508: libffi fails to build on VFP asm instructions, seems to need a '.fpu vfp' directive. Probably missed earlier because my toolchain was configured with --with-fpu=vfp. - PR45416: 4.6 code generation regression on ARM, after expand from SSA changes. Looking at this currently.
== This week == * Look at Linaro issues with higher priority. * Continue working on GCC PRs.
