* GCC
Identified the latent bug that's upset my NEON-shifts testing. It turns
out the define-insn-and-shift patterns in arm/sync.md have no length
attributes set.
Now that the NEON 64-bit shifts appear to be not broken, I've relaunched
the 64-bit extend testing.
Identified the problem with my NEON-64-bit-negate patch: I already knew
it works better (produces more optimal code) with my NEON-immediates
patch, but it turns out that at -O0 the other patch is a hard
requirement or else bad things happen in output_move_vfp.
Backported Ramana's patch for ARM-mode testing of my recent Thumb 64-bit
test cases. I've applied it to Linaro GCC directly, without a merge
proposal, as it's a very low-risk patch.
Caught up with some launchpad blueprint fiddling.
Completed the merges from 4.6 and 4.7 FSF. The 4.7 merge was tricky as
it required working around a BZR bug; I've posted the workaround to the
toolchain list.

On leave on Tuesday
Public holiday on Friday.
Attached a copy of the ARM Linux ABI document to KBentry 39 so we're
hosting it somewhere, at least. Posted an internal Mentor/CS question
about getting its old home restored, and getting a relicensed edition to
allow others to use it as the basis for a hard-float equivalent.
