[PATCH] D142482: [Codegen][ARM][AArch64] Support symmetric operations on complex numbers

[Nicholas Guy via Phabricator via llvm-commits]

NickGuy updated this revision to Diff 493952.
NickGuy retitled this revision from "[CodeGen][ARM][AArch64] Support complex additions with no rotation" to "[Codegen][ARM][AArch64] Support symmetric operations on complex numbers".
NickGuy edited the summary of this revision.
NickGuy added a comment.

I've changed the approach to not be so focused on "complex addition with zero rotation", and instead common operations applied to both sides (dubbed "symmetric operations"). The current implementation doesn't allow for targets to define their own supported operations, but also I'm not sure if there are many (if any at all) operations that wouldn't be common.
