pass_manager: Fix ICE with -fdump-passes -fdisable-tree-* [PR93874]
dump_passes pushes a dummy function for which it evaluates the gates and checks whether the pass is enabled or disabled. Unfortunately, if any -fdisable-*-*/-fenable-*-* options were seen, we ICE during is_pass_explicitly_enabled_or_disabled because slot is non-NULL then and the code will do: cgraph_uid = func ? cgraph_node::get (func)->get_uid () : 0; but the dummy function doesn't have a cgraph node. So, either we need to create and then remove a cgraph node for the dummy function like the following patch, or function.c would need to export the in_dummy_function flag (or have some way to query that flag from other TUs) and we'd need to check it in is_pass_explicitly_enabled_or_disabled. 2020-02-25 Jakub Jelinek <jakub@redhat.com> PR middle-end/93874 * passes.c (pass_manager::dump_passes): Create a cgraph node for the dummy function and remove it at the end. * gcc.dg/pr93874.c: New test.
