* Investigated bootstrap comparison failure with neon-shifts branch; tracked down root cause to pre-existing bug in GCC common code. Fix checked in to FSF mainline and 4.7 branch.

* Investigated di-sync-multithread test case failure with neon-shifts branch; root cause was missing length attributes for sync.md insn&split patterns. Implemented fix and restarted tests.

* Investigated LP bug 1020601, missed optimization with multiple __builtin_unreachable calls. Tracked down root cause and started discussion of possible fixes on gcc-patches.

* Investigated potential reload bug reported by ARM.
