== Issues ==

* None

== Progress ==

* Conditional compare (CCMP)
  - Design tens of test cases to verify the codes.
  - Handle CCMP in vrp pass. If the compare in CCMP can be simplified,
CCMP will be converted to a copy, compare or a bit operator.
  - Investigating to handle CCMP in jump-thread related optimization.
  - Investigating bootstrap issue when expanding conditional compare
to optimized RTL.
    . It seams that there are illegal combinations of different
compares since bootstrap OK if the two compares of CCMP have the same
CODE.
    . Current check bases on function "arm_select_dominance_cc_mode".
Need narrow down the root cause.

== Plan ==

* Continue on conditional compare.

== Panned leaves ==

* Sept. 3-6: internal meeting.
