Strange, because sahf has _no_ suffix or operands:
(define_insn "x86_sahf_1"
[(set (reg:CC FLAGS_REG)
(unspec:CC [(match_operand:HI 0 "register_operand" "a")]
UNSPEC_SAHF))]
"TARGET_SAHF"
"sahf"
[(set_attr "length" "1")
(set_attr "athlon_decode" "vector")
(set_attr "amdfam10_decode" "direct")
(set_attr "mode" "SI")])
And double strange, because athlon should not generate sahf, as it is not in
TARGET_USE_SAHF group of processors.
Could you post the temporary asm (only lines around line 820 will be enough) to
check what is going wrong?
