gcc-4.1-200506011 compiler ICE's using -ftree-vectorize AND
-fdump-tree-all-details-stats in conjunction. Leave out one of both
options and you got a successful compilation.
Command:
/opt/gcc-4.1-20050611/bin/gcc -O3 -march=pentium4 -msse3 -save-temps
test.c -o test -ftree-vectorize -ftree-vectorizer-verbose=5
-fdump-tree-all-details-stats
Error message:
test.c: In function 'main':
test.c:2: internal compiler error: in op_iter_init_maydef, at
tree-flow-inline.h:1065
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
Source Code (I wrote a stupid little program to reproduce the error):
int main(void)
{
int a[1024];
int b[1024];
int c[1024];
int i, j = 0;
for (i = 0; i < 1024; i++) {
a[i] = i;
b[i] = 1023 - i;
}
for (i = 0; i < 1024; i++)
c[i] = a[i] + b[i];
for (i = 0; i < 1024; i++)
j = j + c[i];
return j;
}

this soon.

P.S.: Why comes .c.t59.copyprop4 before .c.t72.copyprop3 (At that point the ICE
seems to occur)?

I forgot to mention this is due to how tree-optimizate works, it is really a bug (a known one), please file
so we don't lose track of it.

Sorry, I didn't understood your answer fully (stupid me :-)
So is it entered in the BugZilla database, shall I enter it or shall we leave it
alone?

It is known meaning people have reported it to the GCC list before but that is it.
A new bugzilla bug would be nice to keep track of it.
