Thank you for the reply, I've compiled this with the most recent patch and also didn't see a problem (but can't get it running with rustc). Building the .ll with the older patch, the same issue also occurs, so I *do* think its the old patch version?
Here is the log output for the riscv32e
F27886013: llvm_output <https://reviews.llvm.org/F27886013>

(and as a sanity check riscv32i)
F27886014: llvm_output_riscv32i <https://reviews.llvm.org/F27886014>

The errant code seems to get introduced here:

  # *** IR Dump After Prologue/Epilogue Insertion & Frame Finalization (prologepilog) ***:
  # Machine code for function _ZN13miscomp_repro4test17h065760f827b95d43E: NoPHIs, TracksLiveness, NoVRegs, TiedOpsRewritten, TracksDebugUserValues

  bb.0.start:
    $x2 = frame-destroy ADDI $x8, 0
    PseudoRET
