------- Comment #11 from drow at gcc dot gnu dot org 2006-08-25 19:57 -------
I am looking at this.
The difference between those two compilers in t16.ssa is:
- # blist_1 = PHI <blist_6(2), blist_7(1)>;
+ # blist_1 = PHI <blist_7(1), blist_6(2)>;
The difference in t17.alias1 is that, plus:
-Variable: list, UID 2, int[31], is addressable, call clobbered, default def:
list_4
+Variable: list, UID 2, int[31], is addressable, default def: list_4
-blist_1, points-to anything, points-to vars: { list }
+blist_1, points-to anything
-list, UID 2, int[31], is addressable, call clobbered, default def: list_4
+list, UID 2, int[31], is addressable, default def: list_4
I'm pretty positive the patch shouldn't have changed what's call clobbered!
This should be easy to track down.
