re PR ipa/70785 (LTO bootstrap with IPA PTA is broken)
2016-04-27 Richard Biener <rguenther@suse.de>
PR ipa/70785
* tree-ssa-structalias.c (refered_from_nonlocal_fn): New
function cummulating used_from_other_partition, externally_visible
and force_output from aliases.
(refered_from_nonlocal_var): Likewise.
(ipa_pta_execute): Use call_for_symbol_and_aliases to cummulate
node flags properly.
