Hello,
there seems to be a gcc problem with the target 'score':

Can you do two things for me, first supply what is the date on 4.3.0 you are
trying to compile? Second, can you attach the preprocessed source found by
recompiling the source which is failing with -save-temps?

------- Comment #2 from ian at airs dot com 2007-02-28 02:24 -------
The problem is that the bitset_c insn comes before the iorsi3 insn in the MD
files. It matches the ior:SI insn with one added clobber. Unfortunately, the
added clobber is of a hard reg, and so this is rejected by insn_invalid_p in
recog.c.
I don't understand how bitset_c will ever be used in practice. Nothing
generates it explicitly. Typical ior:SI insns get passed to recog_memoized
which does not add clobbers.
I can fix the problem easily enough by moving (include "misc.md") and (include
"mac.md") to the end of score.md. I'm not sure how to really test that fix.

And I think the pattern is incorrect anyways, lets look at it:
(define_insn "bitset_c"
[(set (match_operand:SI 0 "register_operand" "=e,d")
(ior:SI (match_operand:SI 1 "register_operand" "0,d")
(match_operand:SI 2 "const_pow2")))
(clobber (reg:CC CC_REGNUM))]
No constraints on the operand 2, that is bad news for after reload.

I will remove the bitclr_c,bitset_c and bittgl_c pattern
from misc.md, they have not to many use.
