[PATCH] D31359: [GlobalISel]: Allow backends to custom legalize Intrinsics

[Aditya Nandakumar via Phabricator via llvm-commits]

aditya_nandakumar added a comment.

The other (easier) approach is to reportGlobalISelFailure on intermediate instructions whenever we're unable to legalize/Lower them. That means, the backend custom lowering code could erase the instructions that it needs, and won't have to worry about calling reportGlobalISelfailure on erased instructions.
