[Ana Pazos via Phabricator via cfe-commits]

apazos added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVFrameLowering.cpp:631
+      MachineBasicBlock::iterator NewMI =
+          BuildMI(MBB, MI, DL, TII.get(RISCV::PseudoCALL))
+              .add(MI->getOperand(0));
----------------
Where are we making sure the PseudoCALL result in a0 is alive through the riscv_restore call?
