Subject: [FastISel] Move the helper function isCommutativeIntrinsic into FastISel base class.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=07731b34fb7482d18f9f2ff4e69a525b9cb58878;p=oota-llvm.git

[FastISel] Move the helper function isCommutativeIntrinsic into FastISel base class.

Move the helper function isCommutativeIntrinsic into the FastISel base class,
so it can be used by more than just one backend.
