[PATCH] D125760: [LegalizeTypes][VP] Add integer promotion support for vp.fptosi/vp.fptoui

[Pretty-box via Phabricator via llvm-commits]

Pretty-box added inline comments.


================
Comment at: llvm/lib/CodeGen/SelectionDAG/LegalizeIntegerTypes.cpp:673
 
+  if (N->getOpcode() == ISD::VP_FPTOUI &&
+      !TLI.isOperationLegal(ISD::VP_FPTOUI, NVT) &&
----------------
Does this code need to be added？Because ISD::VP_FPTOUI/ISD::VP_FPTOSI is considered illegal on RISCV(use custom model) . From the illegal FPTOUI test results, signed conversion instruction is used rather than unsigned conversion instruction. Is this result correct?@craig.topper
