Hi,we generally do not have ther ability to propagate constants to and clone CHKP instrumented functions. Therefore we do not propagate stuff into their lattices but since Honza changed cloning for all contexts heuristics a few weeks ago, we might attempt to clone them for unused parameter removal, which then leads to an ICE (and all sorts of issues). The heuristics however should not attempt to do that because the function cgraph_node has can_change_signature flag cleared. So this patch changes it accordingly. Bootstrapped and tested on x86_64-linux, OK for trunk? Thanks, Martin 2016-01-08 Martin Jambor <mjam...@suse.cz> PR ipa/69044 * ipa-cp.c (estimate_local_effects): Do not clone for removal of useless parameters if we cannot change function signature.
OK. jeff
