* 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.
