[PATCH] D142102: [RISCV] Combine FP_TO_INT to vfwcvt/fvncvt

[Yeting Kuo via Phabricator via llvm-commits]

fakepaper56 added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:9592
+    // their operand types
+    if (!(VT.getScalarSizeInBits() == SrcVT.getScalarSizeInBits() ||
+          IsNarrowing || IsWidening))
----------------
Is it better to use `VT.getScalarSizeInBits() > SrcVT.getScalarSizeInBits() * 2 || VT.getScalarSizeInBits() * 2 < SrcVT.getScalarSizeInBits()` ?
