--- Comment #7 from Diego Novillo <dnovillo at gcc dot gnu.org> 2011-02-02 17:53:16 UTC --- Author: dnovillo Date: Wed Feb 2 17:53:08 2011 New Revision: 169619 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=169619 Log: PR target/47237 * cgraph.h (cgraph_local_info): New field can_change_signature. * ipa-cp.c (ipcp_update_callgraph): Only compute args_to_skip if callee signature can change. (ipcp_estimate_growth): Call sequence simplify only if calle signature can change. (ipcp_insert_stage): Only compute args_to_skip if signature can change. (cgraph_function_versioning): We can not change signature of functions that don't allow that. * lto-cgraph.c (lto_output_node): Stream local.can_change_signature. (lto_input_node): Likewise. * ipa-inline.c (compute_inline_parameters): Compute local.can_change_signature. * ipa-split.c (visit_bb): Never split away APPLY_ARGS. * tree-sra.c (ipa_sra_preliminary_function_checks): Give up on functions that can not change signature. * i386.c (ix86_function_regparm, ix86_function_sseregparm, init_cumulative_args): Do not use local calling conventions for functions that can not change signature.
