[PATCH] D151414: [RISCV] Add Zvfhmin extension support for llvm RISCV backend.

[Yueh-Ting (eop) Chen via Phabricator via llvm-commits]

eopXD added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVInstrInfoVPseudos.td:6702
+// Define vfncvt.f.f.w for f16 when Zvfhmin is enable.
+defvar F16WidenableFloatVectors = !filter(fvtiToFWti, AllWidenableFloatVectors,
+                                          !eq(fvtiToFWti.Vti.Scalar, f16));
----------------
Nit: My mind is thinking of the sentence "this variable collects widen-able floating-point vectors that is widened from f16". I think the naming here didn't help me understand the code and I have actually read the RHS to understand the code here. Maybe we can improve this naming a nit.
