== GCC related == * CS Issue #10201 / PR46883, unrecognizable insn ICE when compiling Samba. Fixed this by changing the predicates of two split patterns. Patch reviewed in CS internally and upstream, committed upstream, will backport to SG++ and Linaro soon.

* LP:641397/PR46888: bitfield insert optimization. Andrew Pinski found a testcase that escapes the CSE patch gets handled by combine, and also found another bug with REG_EQUIV notes. Only looked at this minimally last week, will really work on this later.

* LP:687406/PR46865, -save-temps creating different code. Backported and bzr-pushed the upstream fix by Jakub Jelinek.

* PR45416, ARM code regression. Mostly can generate what I wanted by now, under ARM and x86, although patch is still not in a submittable state.

* VFP index patch. Uncommitted GCC patch of mine from last year; added Thumb-2 bits and corrected some things in the testcase. Committed upstream.

== This week == * Really get January travel stuff nailed. * Upstream patch review is probably going to start getting slow/suspended this week. Will probably do some study stuff on larger projects. * Continue to look at GCC issues.
