[PATCH] D102031: [RISCV] Use X0 as destination of inserted vsetvli when possible.

[Jessica Clarke via Phabricator via llvm-commits]

jrtc27 added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVInsertVSETVLI.cpp:270
+  Register DestReg = RISCV::X0;
+  if (Info.getAVLReg() == RISCV::X0)
+    DestReg = MRI->createVirtualRegister(&RISCV::GPRRegClass);
----------------
Use the existing `AVLReg` variable rather than repeating the call?
