--- Additional Comments From giovannibajo at libero dot it 2005-03-15 13:48 --- Confirmed. Please, could the autovect people remember to confirm bugs when they look at them? If you have troubles with Bugzilla privileges and e-mail accounts, contact me in private. Another thing: should we consider easily-backported fixes for ICEs also for the 4.0 branch? I guess it makes sense if they are isolated in the vectorizer code. ICEs prevent users from test the new feature, even if it is preliminar.

The problem is that we take the size_type of a void type, and pass null to
fold_convert in vect_analyze_pointer_ref_access.
So one thing to do is to make sure that we're dealing with a complete type:
*** vect_analyze_pointer_ref_access (tree me
*** 1321,1326
--- 1403,1416
*ptr_step = fold_convert (ssizetype, step);
innertype = TREE_TYPE (reftype);
+ if (!COMPLETE_TYPE_P (innertype))
+ {
+ if (vect_print_dump_info (REPORT_UNVECTORIZED_LOOPS,
+ LOOP_LOC (loop_vinfo)))
+ fprintf (vect_dump, not vectorized: pointer to incomplete type.);
+ return NULL;
+ }
+
/* Check that STEP is a multiple of type size. */
if (!integer_zerop (size_binop (TRUNC_MOD_EXPR, *ptr_step,
fold_convert (ssizetype, TYPE_SIZE_UNIT (innertype)
This solves the ICE, but I noticed that we're actually looking at the wrong
type - we're interested in the type of the data-reference, not the type of
its 'init'. The following is what we want (also solves the ICE):
*** vect_analyze_pointer_ref_access (tree me
*** 1310,1317
return NULL;
}
! reftype = TREE_TYPE (init);
! if (!POINTER_TYPE_P (reftype))
{
if (vect_print_dump_info (REPORT_UNVECTORIZED_LOOPS,
LOOP_LOC (loop_vinfo)))
--- 1393,1399
return NULL;
}
! if (!POINTER_TYPE_P (TREE_TYPE (init)))
{
if (vect_print_dump_info (REPORT_UNVECTORIZED_LOOPS,
LOOP_LOC (loop_vinfo)))
I'll bootstrap/test and submit.
