== Linaro and upstream GCC == * LP #674146, dpkg segfaults during debootstrap on natty armel: analyzed and found this should be a case of PR44768, backported mainline revision 161947 to fix this.

* LP #641379, bitfields poorly optimized. Discussed some with Andrew Stubbs.

* GCC bugzilla PR45416: Code generation regression on ARM. Been looking at this regression, that started from the expand from SSA changes since 4.5-experimental. The problem seems to be TER not properly being substituted during expand (compared to prior "convert to GENERIC then expand"). I now have a patch for this, which fixes the PR's testcase, but when testing current upstream trunk, hit an assert fail ICE on several testcases in the alias-oracle; it does however, test without regressions on a 4.5 based compiler. I am still looking at the upstream failures.

== This week == * Continue with GCC issues and PRs. * Think about GCC performance opportunities (Linaro)
