[PATCH] D96122: [GlobalISel] Start using vectors in GISelKnownBits

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

Some tests for the non-splat case would be nice



================
Comment at: llvm/lib/CodeGen/GlobalISel/GISelKnownBits.cpp:164
     break;
+  case TargetOpcode::G_BUILD_VECTOR: {
+    // Collect the known bits that are shared by every demanded vector element.
----------------
As a follow up should also try to handle G_BUILD_VECTOR_TRUNC
