Posted a new patch for 16 -> 64 bit multiply and accumulate: http://www.mail-archive.com/gcc-patches@gcc.gnu.org/msg05794.html Pushed the same patch to a Launchpad branch for testing.
Pinged my addw/subw patch as a review didn't seem forthcoming.
Worked on a canonical form for HImode to DImode multiple-and-accumulate. The problem isn't too hard to fix, but it's hard to do it in a nice way.
Attended Nathan S's reorg call. Followed up by talking to Nathan F about what he's been working on with Wind River. Read up on the Wiki.
Looked at why the ARM smlal{tb,bt,tt} instructions are not generated. I've added the proper patterns, but combine doesn't match them, and I've run out of time this week to check why.
