(struct cgraph_local_info): new used_from_object_file flag. * cgraph.c (dump_cgraph_node): dump used_from_object_file flag. (cgraph_clone_node): initialize used_from_object_file. (cgraph_create_virtual_clone): initialize used_from_object_file. * lto-symbtab.c (lto_symtab_merge_decls_1): Set used_from_object_file flags for symbols of LDPR_PREVAILING_DEF when compiling with -fwhole-program. (lto_symtab_resolve_symbols) Use LDPR_PREVAILING_DEF_IRONLY for internal resolver. * ipa.c (function_and_variable_visibility): Set externally_visible flag of varpool_node if used_from_object_file flag is set. (cgraph_externally_visible_p): check used_from_object_file flag. * doc/invoke.texi (-fwhole-program option): Change description of externally_visible attribute accordingly. * doc/extend.texi (externally_visible): Ditto. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@161483 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/cgraph.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'gcc/cgraph.h') diff --git a/gcc/cgraph.h b/gcc/cgraph.h index 2c7ddbf123c..ef556b9cd7f 100644 --- a/gcc/cgraph.h +++ b/gcc/cgraph.h @@ -102,6 +102,9 @@ struct GTY(()) cgraph_local_info { /* Set when function is visible by other units. */ unsigned externally_visible : 1; + /* Set when resolver determines that function is visible by other units. */ + unsigned used_from_object_file : 1; + /* Set once it has been finalized so we consider it to be output. */ unsigned finalized : 1; @@ -487,6 +490,8 @@ struct GTY((chain_next ("%h.next"), chain_prev ("%h.prev"))) varpool_node { unsigned output : 1; /* Set when function is visible by other units. */ unsigned externally_visible : 1; + /* Set when resolver determines that variable is visible by other units. */ + unsigned used_from_object_file : 1; /* Set for aliases once they got through assemble_alias.
