== 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.
