== Issues ==

* None

== Progress ==

* Take care Linaro binaries release (1/10).
* Send out ccmp patches for community review (TCWG-488, 1/10).
* loop2_invariants heuristics tune (1/10, TCWG-469). One patch was
committed @r212135.
* Constant optimization (TCWG-486, 7/10 )
  - Try to keep constant in register when expanding. But benchmark
results show regression due to combine behavior changes.
  - Try to keep unsigned constant when expanding. For crc |= 0x8000,
crc is unsigned short. If 0x8000 is represented as unsigned value, no
need to split 0x8000. But in middle-end, wide_int_storage::set_len and
trunc_int_for_mode always do sign extension. "trunc_int_for_mode
(INTVAL (op), mode) == INTVAL (op)" is always checked when checking
operand (e.g. in general_operand of recog.c). And in RTL, there is no
"unsigned" information at all.

== Plans ==

* Update ccmp patches according to comments.
* Continue on constant optimization.
* Ping pending patches.
