Subject: [PATCH, i386]: Introduce *<sse>_maskcmp<mode>3_comm to handle commutative compares

Hello!

Some SSE "maskcmp" compares are commutative, so we can use % operand
modifier in these cases.  The patched gcc generates one movaps less
for the testcase of PR49133.

2011-05-25  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/sse.md (*<sse>_maskcmp<mode>3_comm): New pattern.

Tested on x86_64-pc-linux-gnu {, -m32}, committed to mainline SVN.

Uros.
