------- Comment #7 from rguenth at gcc dot gnu dot org 2008-11-02 12:48 -------
We take a long time in compute_antic in the loop
for (i = 0; i < last_basic_block - NUM_FIXED_BLOCKS; i++)
{
if (TEST_BIT (changed_blocks, postorder[i]))
{
basic_block block = BASIC_BLOCK (postorder[i]);
changed |= compute_antic_aux (block,
TEST_BIT (has_abnormal_preds,
block->index));
}
}
(gdb) print cfun->cfg->x_last_basic_block
$22 = 3220
and some invocations of compute_antic_aux take a really long time during
phi_translate_set because the to translate set is really large (it has
in one case 11885 elements).
probably not much to do here ...
