[PATCH] D103313: [RISCV][Clang] Implement support for zmmul-experimental

[ksyx via Phabricator via cfe-commits]

ksyx added a comment.

I have took a look into `ELFObjectFile.cpp` but I am not sure what work I need to do there since it seems other Z* extensions are not being handled there.



================
Comment at: llvm/lib/Target/RISCV/RISCVSubtarget.h:38
   bool HasStdExtM = false;
+  bool HasStdExtZmmul = false;
   bool HasStdExtA = false;
