A reduced test case for -O2
The attached test case generates an invalid instruction like
"div0s @(4,r8),r1" with -O2. It seems that
(define_insn "*cmp_div0s_0"
[(set (reg:SI T_REG)
(eq:SI (lshiftrt:SI (match_operand:SI 0 "arith_reg_operand")
(const_int 31))
(ge:SI (match_operand:SI 1 "arith_reg_operand")
(const_int 0))))]
"TARGET_SH1"
"div0s %0,%1"
[(set_attr "type" "arith")])
has no constraints.
