[PATCH] D150670: [WebAssembly] Disable generation of fshl/fshr for rotates

[Derek Schuff via Phabricator via cfe-commits]

dschuff added a comment.

FWIW X86 seems to do something similar elsewhere in this file (https://github.com/llvm/llvm-project/blob/main/clang/lib/CodeGen/CGBuiltin.cpp#L985-L986), although it doesn't seem common otherwise. I think I'd be OK with this approach (and it does seem better than trying to mess with instcombine or a new TTI hook or something)
