But its only user, insert_branch(), doesn't need REPEAT_CFG_CLEANUP to be set. So, simplify this wrapper by keeping only the call to remove_bb_from_list(). --- linearize.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/linearize.c b/linearize.c index ebb03217c9d9..6bb1287efcb0 100644 --- a/linearize.c +++ b/linearize.c @@ -695,8 +695,6 @@ static void set_activeblock(struct entrypoint *ep, struct basic_block *bb) static void remove_parent(struct basic_block *child, struct basic_block *parent) { remove_bb_from_list(&child->parents, parent, 1); - if (!child->parents) - repeat_phase |= REPEAT_CFG_CLEANUP; } /* Change a "switch" or a conditional branch into a branch */
