[PATCH] D148917: [AArch64][FastISel] Handle CRC32 intrinsics

[Alexis Engelke via Phabricator via llvm-commits]

aengelke added a comment.

We care a lot about compile times and in our application, GlobalISel (when it succeeds, about 10% fallback rate) increases compile times by ~50% compared to FastISel. We do plan to look at GlobalISel performance at some point, but it seems like there's a lot of work to be done to bring it at least on-par with FastISel wrt. compile times.
