[Petar Avramovic via Phabricator via llvm-commits]

Petar.Avramovic added inline comments.


================
Comment at: llvm/lib/CodeGen/GlobalISel/GISelKnownBits.cpp:171
+
+      computeKnownBitsImpl(MI.getOperand(i + 1).getReg(), Known2, DemandedElts,
+                           Depth + 1);

We don't have such computeKnownBitsImpl in global-isel. Sdag computeKnownBits(SrcOp, Depth + 1) will call computeKnownBits(Op, 'allones', Depth).
