State-Changed-Why:
    PPC, reproduced on entropy, .i attached.
    
    Actually another incarnation of the CLOBBER problem, but harder to fix this time. This pattern around line 10730 in rs6000.md is the culprit:
    
    (define_insn ""
      [(set (match_operand:SI 0 "gpc_reg_operand" "=r,r,r,r,r")
            (eq:SI (match_operand:SI 1 "gpc_reg_operand" "%r,r,r,r,r")
                   (match_operand:SI 2 "reg_or_cint_operand" "r,O,K,L,I")))
       (clobber (match_scratch:SI 3 "=r,&r,r,r,r"))]
      "! TARGET_POWERPC64"
      "@
       xor %0,%1,%2\;{sfi|subfic} %3,%0,0\;{ae|adde} %0,%3,%0
       {sfi|subfic} %3,%1,0\;{ae|adde} %0,%3,%1
       {xoril|xori} %0,%1,%b2\;{sfi|subfic} %3,%0,0\;{ae|adde} %0,%3,%0
       {xoriu|xoris} %0,%1,%u2\;{sfi|subfic} %3,%0,0\;{ae|adde} %0,%3,%0
       {sfi|subfic} %0,%1,%2\;{sfi|subfic} %3,%0,0\;{ae|adde} %0,%3,%0"
      [(set_attr "length" "12,8,12,12,12")])

    Please specify which architecture this is on (ppc?, sh?)
    and provide preprocessed testcase (see
