------- Comment #15 from jakub at gcc dot gnu dot org 2007-10-28 19:10 ------- Compared to 20070803 with -O3 -fno-tree-vectorize there are now 100 times more calls to rtx_needs_barrier and 44 times more calls to safe_group_barrier_needed. E.g. the latter is horribly expensive, e.g. copying around 401 * sizeof (struct reg_write_state) == 1604 bytes several times.
