The only issue here is that tree-vect-generic uses this to delete statements they have lowered but stmt_unremovable_because_of_non_call_eh_p might return true for those. So I might need an other argument to simple_dce_from_worklist about that ... Let me try without the argument first. ^ permalink raw reply [flat|nested] 7+ messages in thread

In this case, execute_fixup_cfg removes a store (correctly) and then removes the null load (incorrectly) due to not checking stmt_unremovable_because_of_non_call_eh_p. This patch adds the check in the similar way as the patch to fix PR 100382 did. gcc/ChangeLog: * tree-ssa-dce.c (simple_dce_from_worklist): Check stmt_unremovable_because_of_non_call_eh_p also before removing the statement. ^ permalink raw reply [flat|nested] 7+ messages in thread
