void fdct_int32()
{
int tmp4, tmp5, tmp7;
int z1, z2, z3, z4, z5;
int *dataptr;
int i;
for (i = 0; i < 8; i++) {
tmp7 = dataptr[0];
z3 = tmp4;
z4 = tmp5 + tmp7;
z5 = (z3 + z4) * ((int) 9633);
z3 += z5;
dataptr[56] = tmp4 + z1 + z3;
dataptr[40] = tmp5 + z2 + z4;
dataptr++;
}
}
When compiling the above file with the following command line arguments:
gcc -c -O -march=pentium4 -ftree-vectorize foo.c
I get the following error:
foo.c: In function 'fdct_int32':
foo.c:22: internal compiler error: in push_reload, at reload.c:1303
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
I discovered this while trying to compile the xvid sources using silly CFLAGS
by accident. The above file is a somewhat reduced testcase.
