Hi, the following patch adds streaming ofcgraph_node.ipa_transforms_to_apply so that transformation phases of IPA passes are run in LTO too. It is done by simple streaming of pass.static_pass_number and then looking it up among all_regular_ipa_passes.
Bootstrapped and tested on x86_64-linux, required to make aggregate IPA-CP work in LTO. OK for trunk? Thanks, Martin 2012-11-03 Martin Jambor <mjam...@suse.cz> * lto-cgraph.c: Include tree-pass.h. (lto_output_node): Stream node->ipa_transforms_to_apply. (input_node): Likewise. * Makefile.in (lto-cgraph.o): Add TREE_PASS_H to dependencies.
