--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Guess latent since r12-2601 , but it is actually late_combine2 that propagates
it.
There is a mismatch on the mode iterators introduced by that commit,
(define_insn_and_split ""
[(set (pc)
(if_then_else (match_operator 3 "eqne_operator"
[(zero_extract:QHSI (match_operand:QHSI 1
"register_operand" "r")
(const_int 1)
(match_operand 2
"const_int_operand" "n"))
(const_int 0)])
(label_ref (match_operand 0 "" ""))
(pc)))]
in jumpcall.md uses QHSI, but
(define_insn ""
[(set (reg:CCZ CC_REG)
(eq (zero_extract:HSI (match_operand:HSI 0 "register_operand" "r")
(const_int 1)
(match_operand 1 "const_int_operand" "n"))
(const_int 0)))]
in testcompare.md uses HSI.

fixes this, but what do I know about h8300...
