== This week ==

* Looked a bug report that the fix for LP #736007 had caused regressions on powerpc-darwin. It turned out to be a target-specific bug; the backend has the same const_vector code as i386 and spu, but the fix for PR34856 was never applied there. I'll submit the patch (and backport to Linaro 4.6) once the bug submitter has had a chance to test it.

* Experimented with -falign-loops. Found that it triggered a bug in the ARM minipool layout code. Posted patch upstream and committed. Backported to 4.6.

* Committed patch to allow globs in define_bypass.

* Updated auto inc/dec patch after comments from Bernd and Stephen. I'm pretty happy with it now, but there are a couple of prerequisite patches I need to sort out first.

* Started getting those prerequisites ready.

* Decided that we needed something a bit more subtle than my original insn_rtx_cost patch: at the moment, we simply don't use rtx costs for lvalues. Wrote a series of patches to "improve" the rtx_cost interface, including providing the outer operand number and an indication of whether the rtx is an lvalue or an rvalue.

* Upgraded my laptop. This turnted out to be more eventful than anticipated, and ended up taking a whole day.

== Next week ==

* Post auto inc/dec preparatory patches for review. Hopefully post an RFA for the pass itself.
