From 3c97c75dbc59497ed3a56c20eb66a50f554c4a6a Mon Sep 17 00:00:00 2001 From: hubicka Date: Wed, 26 Jan 2011 14:06:20 +0000 Subject: 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@169290 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/cgraph.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'gcc/cgraph.h') diff --git a/gcc/cgraph.h b/gcc/cgraph.h index 33b31679535..2df3fa54d9f 100644 --- a/gcc/cgraph.h +++ b/gcc/cgraph.h @@ -114,6 +114,10 @@ struct GTY(()) cgraph_local_info { Currently computed and used only by ipa-cp. */ unsigned versionable : 1; + /* False when function calling convention and signature can not be changed. + This is the case when __builtin_apply_args is used. */ + unsigned can_change_signature : 1; + /* True when function should be inlined independently on its size. */ unsigned disregard_inline_limits : 1; -- cgit v1.2.1
