Failing preprocessed C source code
To see wether this problem can also be exposed with the C
frontend, I ran the subroutine through f2c and preprocessed it
with "gcc -E".
Still the same error:
$ gcc -O3 -g -march=athlon-xp -mfpmath=sse -mno-80387 ddot.i
ddot.c: In function 'ddot_':
ddot.c:91: error: insn does not satisfy its constraints:
(insn 346 345 347 8 ddot.c:53 (set (reg:DF 21 xmm0 [103])
(mem:DF (plus:SI (reg/f:SI 6 bp)
(const_int -128 [0xffffff80])) [0 S8 A8])) 64
{*movdf_nointeger} (nil)
(nil))
ddot.c:91: internal compiler error: in reload_cse_simplify_operands, at
postreload.c:391
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
so this is indeed independent of the front end.
