craig.topper added inline comments.
================
Comment at: clang/utils/TableGen/RISCVVEmitter.cpp:1321
ListSeparator LS(" && ");
+ // Full multiplies for EEW=64 require V.
+ if (PredefinedMacros & RISCVPredefinedMacro::V)
----------------
It's not as useful here. Should put it on line 812 where the condition is
