So, I was wondering about patterns like:
(define_insn_and_split "*setcc_di_1"
[(set (match_operand:DI 0 "register_operand" "=q")
(match_operator:DI 1 "ix86_comparison_operator"
[(reg FLAGS_REG) (const_int 0)]))]
"TARGET_64BIT && !TARGET_PARTIAL_REG_STALL"
"#"
"&& reload_completed"
[(set (match_dup 2) (match_dup 1))
(set (match_dup 0) (zero_extend:DI (match_dup 2)))]
{
PUT_MODE (operands[1], QImode);
operands[2] = gen_lowpart (QImode, operands[0]);
})
on the x86. X86 is an always LRA port, and with LRA it seems reload_completed
is always 0, and so that disables these splitters?
I have a port that I am converting, and noticed this and am wondering what the
path forward is for me.
