------- Comment #2 from wouter dot vermaelen at scarlet dot be 2008-08-20 09:38 -------
I can trigger the same ICE with this testcase:
---------------------------------------------------
int* getFoo();
struct Bar {
Bar();
int* foo1;
int* foo2;
int* table[4][4][4];
};
Bar::Bar() {
foo1 = getFoo();
foo2 = getFoo();
for (int a = 0; a < 4; ++a) {
for (int b = 0; b < 4; ++b) {
for (int c = 0; c < 4; ++c) {
table[a][b][c] = foo1;
}
}
}
}
--------------------------------------------------------
compile with:
g++ -O3 bug.ii

I am testing the following patch:

===================================================================
--- tree-vect-analyze.c (revision 139225)
+++ tree-vect-analyze.c (working copy)
@@ -2531,7 +2535,7 @@ vect_get_and_check_slp_defs (loop_vec_in
/* Check if DEF_STMT is a part of a pattern and get the def stmt from
the pattern. Check that all the stmts of the node are in the

If everything goes OK, I will submit it tomorrow.
