This instruction should be split waaay before reg-stack. The problem was
probably introduced by the patch below:
2009-06-28 Paolo Bonzini <bonz...@gnu.org>
* config/i386/i386.h (enum ix86_fpcmp_strategy): New.
* config/i386/i386.md (cbranchxf4, cstorexf4, cbranch<MODEF>4,
cstore<MODEF>4, mov<X87MODEF>cc): Change predicate to
ix86_fp_comparison_operator.
(*fp_jcc_1_mixed, *fp_jcc_1_sse, *fp_jcc_1_387, *fp_jcc_2_mixed,
*fp_jcc_2_sse, *fp_jcc_2_387): Delete
(*fp_jcc_3_387, *fp_jcc_4_387, *fp_jcc_5_387, *fp_jcc_6_387,
*fp_jcc_7_387, *fp_jcc_8<MODEF>_387): Eliminate call to
!ix86_use_fcomi_compare, change ix86_fp_jump_nontrivial_p call
to !TARGET_CMOVE, change predicate to ix86_fp_comparison_operator.
(related splits): Change predicate to ix86_fp_comparison_operator.
* config/i386/predicates.md: Use ix86_trivial_fp_comparison_operator
instead of ix86_fp_comparison_codes.
...
Let's ask Paolo.
