Subject: Use intrinsic pattern to make a simpler match
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f575e9f9022cba6e8b45adec38789e53f21ee30b;p=oota-llvm.git

Use intrinsic pattern to make a simpler match

This is a follow-on to r236740 where I took Andrea's advice
in D9504 to remove a redundant pattern...except that I removed
the wrong pattern!

AFAICT, there is no change in the final code produced because
subsequent passes would clean up the extra instructions created
by the more complicated pattern.
