[PATCH] D37680: [X86][SSE] Add support for X86ISD::PACKSS to ComputeNumSignBitsForTargetNode

Mon Sep 11 05:27:38 PDT 2017

RKSimon updated this revision to Diff 114574.
RKSimon added a comment.

Added general test cases (not directly calling PACKSS intrinsic).

I added v16i32/v16i64 cases although these need some further work to be handled in combineLogicBlendIntoPBLENDV
