------- Comment #8 from janis at gcc dot gnu dot org 2007-12-12 23:34 ------- Ira, it seems I've wasted your time; it's a well-known problem (except to me) that -maltivec without -mabi=altivec doesn't work in the general case because vector registers are not saved and restored. That explains why this test passes with either reload.c or reload1.c is compiled without vectorization. Meanwhile there are discussions happening about how to fix this so that someone using "-O3 -mcpu=970" won't run into failures when they don't even realize they're using vector registers.
