Ping?
Patch is rebased and regenerated since [PATCH, 3/10] skip swapping
operands used in ccmp is discarded.
Please find the updated patch in attachment.

Hi,
This patch includes the main logic to expand ccmp instructions.
In the patch,
* ccmp_candidate_p is used to identify the CCMP candidate
* expand_ccmp_expr is the main entry, which calls expand_ccmp_expr_1
to expand CCMP.
* expand_ccmp_expr_1 uses a recursive algorithm to expand
