Author: hubicka Date: Mon Jun 7 15:33:34 2010 New Revision: 160380 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=160380 Log: * cgraph.c (cgraph_edge_cannot_lead_to_return): Also check if caller is noreturn. * ipa-reference.c (analyze_function): Use ipa_ref_cannot_lead_to_return * ipa-ref.h (ipa_ref_cannot_lead_to_return): New function. * ipa-ref.c (ipa_ref_cannot_lead_to_return): New function. * ipa-pure-const.c (check_decl): Add IPA parameter. (state_from_flags): New function. (better_state, worse_state): New functions. (check_call): When in IPA mode, do not care about callees. (check_load, check_store): Update. (check_ipa_load, check_ipa_store): New. (check_stmt): When in IPA mode, use IPA checkers. (analyze_function): Use state_from_flags. (propagate): Check indirect edges and references.
