I've committed (r183305) a slightly changed variant that merges the two
outer bitmap loops again, like so:
+ EXECUTE_IF_AND_COMPL_IN_BITMAP (work, old_conflicts, 0, i, bi)
{
unsigned j;
bitmap_iterator bj;
- EXECUTE_IF_SET_IN_BITMAP (work, i + 1, j, bj)
+ /* First the conflicts between new and old_conflicts. */
+ EXECUTE_IF_SET_IN_BITMAP (old_conflicts, 0, j, bj)
+ add_stack_var_conflict (i, j);
+ /* Then the conflicts between only the new members. */
+ EXECUTE_IF_AND_COMPL_IN_BITMAP (work, old_conflicts, i + 1,
+ j, bj)
add_stack_var_conflict (i, j);
}
Ciao,
Michael.
