# CHECK-INTERESTINGNESS: %{{[0-9]+}}:gpr = ADDI %{{[0-9]+}}, 5

# Verify that after reduction the following instruction sequence remains. The
# interestingness-test 'instr-reduce.py' matches a '%[0-9]+:gpr = ADDI %[0-9]+, 5'
# pattern in the output and that combined with that the MIR has to be valid
# (pass verify) results in the given sequence.

# CHECK:      [[IMPDEF:%[0-9]+]]:gpr = IMPLICIT_DEF
# CHECK-NEXT: %{{[0-9]+}}:gpr = ADDI [[IMPDEF]], 5
# CHECK-NEXT: PseudoRET implicit $x10
