================
Comment at: llvm/lib/Support/RISCVISAInfo.cpp:744
 static const char *ImpliedExtsZfh[] = {"zfhmin"};
+static const char *ImpliedExtsZve64d[] = {"zve64f", "d"};
+static const char *ImpliedExtsZve64f[] = {"zve64x", "zve32f"};
----------------
I think we need to drop the implication of "f" here and "d" on zve64f. Move them to V


================
Comment at: llvm/lib/Target/RISCV/RISCVSubtarget.h:195
+  bool hasVInstructionsF32() const { return HasStdExtZve32f && HasStdExtF; }
+  // FIXME: Consider Zfinx in the future
+  bool hasVInstructionsF64() const { return HasStdExtZve64d && HasStdExtD; }
----------------
Zfinx -> Zdinx
