[PATCH] D49837: [SelectionDAG] Handle unary SelectPatternFlavor for ABS case in SelectionDAGBuilder::visitSelect.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: lib/CodeGen/SelectionDAG/LegalizeDAG.cpp:2596
+  SDValue Shift = DAG.getNode(ISD::SRA, dl, VT, Op,
+                              DAG.getConstant(VT.getSizeInBits() - 1, dl, VT));
+  SDValue Add = DAG.getNode(ISD::ADD, dl, VT, Op, Shift);
----------------
Safer to use getScalaraSizeInBits - in case vector types ever use this.
