[PATCH] D38732: [X86][AVX512] Improve lowering of AVX512 test intrinsics

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

Add the new test files to trunk with current codegen and then rebase to show the diff from this patch.



================
Comment at: lib/Target/X86/X86ISelLowering.cpp:17191
+    if(A.getOpcode() == ISD::AND && ISD::isBuildVectorAllZeros(B.getNode())) {
+     //assert(! ISD::isBuildVectorAllZeros(B.getNode()));
+      MVT VT0 = Op0.getSimpleValueType();
----------------
Drop this


================
Comment at: lib/Target/X86/X86ISelLowering.cpp:17194
+      SDValue RHS = DAG.getNode(ISD::BITCAST, dl, VT0, A.getOperand(0));
+      SDValue LHS = DAG.getNode(ISD::BITCAST, dl, VT0, A.getOperand(1));
+      return DAG.getNode(Opc == X86ISD::PCMPEQM ? X86ISD::TESTNM : X86ISD::TESTM,
----------------
Use DAG.getBitcast
