== GCC related == * PR44557, Thumb-1 ICE: originally thought a fix of constraint will work, however after simplifying the testcase, received another ICE in postreload, due to a load of IP, which is not permitted in Thumb-1. Looking at some reload internals as part of fixing this.
* PR45416, ARM code generation regression. First fix from last week hit an assert FAIL in the alias-oracle due to ARRAY_REFs not being handled there. Also, further found some expand code quality regressions due to this change. Turned to a more conservative fix by adding the related TER substitution to expr.c:do_store_flag(), which produced more focused results. However, 32-bit x86 slightly regressed in the same flag storing code (did not use the 'testl' insn after the change). Still WIP.
* PR46667, submitted a section type conflict bug fix upstream, see http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00137.html , which supposedly fixes the upstream ARM-Linux C++ build. Jan Hubicka later gave another fix, so still in discussion.
* PR45886, this PR is call for backporting the __ARM_PCS* preprocessor symbols to gcc-4_5-branch. Submitted a mail to ask for approval, no response.
== libffi VFP hard-float == * PR46508, libffi VFP assembly error. I missed this earlier due to using a compiler configured with --with-fpu=vfp. Submitted assembly fix to add the needed FPU directives. Committed to upstream trunk.
== This week == * Hope to wrap up the above in-progress PRs, as well as continue to look at other PRs of interest. * LP #685534 popped up on Sunday, and manifests on upstream trunk too. Add this to queue. * Think about GCC performance opportunities (Linaro)
