--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
Ah, and tree-ssa-structalias.c does
/* Build the constraints. */
FOR_EACH_DEFINED_FUNCTION (node)
{
varinfo_t vi;
/* Nodes without a body are not interesting. Especially do not
visit clones at this point for now - we get duplicate decls
there for inline clones at least. */
if (!cgraph_function_with_gimple_body_p (node) || node->clone_of)
continue;
cgraph_get_body (node);
but doesn't apply IPA transforms. I think the kludge in the pass manager
should do that instead. I wonder how the above doesn't trigger the
in_lto_p assert in cgraph_get_body though ... (maybe the odd DECL_RESULT
check makes sure we don't trigger that path).
Ick. That code path triggers also with
2171 do_per_function (clear_last_verified, NULL);
doing the push/pop_cfun game on each fn just to clear last_verified ...
in WPA stage ... same for
2179 do_per_function (update_properties_after_pass, pass);
and more. Trying to make
