[PATCH] D105875: [RISCV] Prevent use of t0(aka x5) as rs1 for jalr instructions.

[Jessica Clarke via Phabricator via llvm-commits]

jrtc27 added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVInstrInfo.td:1006
+def PseudoBRIND : Pseudo<(outs), (ins GPRJALR:$rs1, simm12:$imm12), []>,
                   PseudoInstExpansion<(JALR X0, GPR:$rs1, simm12:$imm12)>;
 
----------------
This is one part of TableGen that I've never quite understood the rules about, but: does the expansion also need to use GPRJALR? (ditto for PseudoCALLIndirect)
