Fix ICE due to incorrect insn type.
;; if reg/mem op
(define_insn_reservation "slm_sseishft_3" 2
(and (eq_attr "cpu" "slm")
(and (eq_attr "type" "sseishft")
(not (match_operand 2 "immediate_operand"))))
"slm-complex, slm-all-eu")
in slm.md it will check operands[2] for type sseishft, but for
extendbfsf2_1 there's no second operand which caused ICE.
The patch set type from sseishft to sseishft1 to fix the issue.
gcc/ChangeLog:
PR target/107934
* config/i386/i386.md (extendbfsf2_1): Change type from
sseishft to sseishft1.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr107934.c: New test.
