------- Comment #3 from jakub at gcc dot gnu dot org 2008-01-03 15:01 -------
Additionally, pass_tree_profile is executed multiple times with -fopenmp, e.g.
on
void foo (int i)
{
#pragma omp parallel
if (i > 2)
bar (i + 1);
else if (i < -2)
bar (i / 2);
else
bar (i * 2);
}
(which compiles) profile counters are added before omp expansion and once again
for the child function. Is there a reason why pass_tree_profile can't run
after
pass_cleanup_cfg/pass_init_datastructures/pass_expand_omp?
If it can't be moved, could it at least skip all edges in omp parallel regions?
Or if it is not thread safe, just disable pass_tree_profile if flag_openmp...
