Committed Kazu's VFP testcases patch upstream.
Merged the latest from upstream GCC 4.6.
Merged all the outstanding launchpad merge requests against both GCC 4.5
Spun the 4.5-2011.03-0 and 4.6-2011.03-0 releases. Passed the tarballs
to Michael H for final testing.
Brought the patch tracker up to date w.r.t. to new merges.
Posted one of Dan's patches upstream for review.
Decided to drop Julian's A8 alignment patch completely. I had previously
discovered it provided no measurable benefit on A8, and now I've found
the same for A9 (Pandaboard). There's no real improvement for any
combination of -falign-* options in EEMBC.
Bernd's "Discourage NEON on A8" patch also doesn't show any value in the
benchmark results, but I think I've forward ported it wrong, because it
should at least change the binary size, and it doesn't. I need to look
into this further.
I also decided I don't know enough about ARMv7, so I spent some time
reading a few chapters from the ARM A.R.M.
Upstream patched requiring review:
* Thumb2 constants:
* ARM EABI half-precision functions
* ARM Thumb2 Spill Likely tweak
* NEON scheduling patch
* RVCT Interoperability patch
