================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:192
+  setOperationAction(ISD::EH_DWARF_CFA, MVT::i32, Custom);
+  setOperationAction(ISD::EH_DWARF_CFA, MVT::i64, Custom);
+
----------------
 Would it be better to only lower i64 EH_DWARF_CFA in RV64? Because the result operand of EH_DWARF_CFA is pointer type and we can't represent an i64 pointer type in RV32.
