The problem is this instruction:
zdep %r29,2,0,%r20
The third operand is the length for the deposit. A length of zero isn't
allowed. Valid lengths are from 1 to 32.
This is the pattern which generated the above instruction:
(define_insn ""
[(set (match_operand:SI 0 "register_operand" "=r")
(and:SI (ashift:SI (match_operand:SI 1 "register_operand" "r")
(match_operand:SI 2 "const_int_operand" ""))
(match_operand:SI 3 "const_int_operand" "")))]
"exact_log2 (1 + (INTVAL (operands[3]) >> (INTVAL (operands[2]) & 31))) >= 0"
"*
{
int cnt = INTVAL (operands[2]) & 31;
operands[3] = GEN_INT (exact_log2 (1 + (INTVAL (operands[3]) >> cnt)));
operands[2] = GEN_INT (31 - cnt);
return \"{zdep|depw,z} %1,%2,%3,%0\";
}"
[(set_attr "type" "shift")
(set_attr "length" "4")])
The RTL that generated the instruction is:
(insn:TI 8138 3652 33318 (set (reg/v:SI 20 %r20 [orig:2429 count ] [2429])
(and:SI (ashift:SI (reg:SI 29 %r29 [1812])
(const_int -3 [0xfffffffd]))
(const_int 1 [0x1]))) 195 {*pa.md:7267} (nil)
(nil))
