(handle_alias_pairs): Set weakref flag, do not set DECL_EXTERNAL. (output_weakrefs): Use weakref flag. * fold-const.c (simple_operand_p): Handle WEAK. * gimple-fold.c (can_refer_decl_in_current_unit_p): Drop weakref. * ipa.c (varpool_externally_visible_p): Drop weakref. (function_and_variable_visibility): Update comment; fix weakref sanity checks; do not clear DECL_WEAK on them. * lto-cgraph.c (lto_output_node): update. (lto_output_varpool_node): Update. (input_overwrite_node): Update. (input_node): Update. (input_varpool_node): Update. * lto-symtab.c (lto_symtab_symbol_p): Do not special case weakrefs. (lto_symtab_merge_symbols): Add sanity check. (lto_symtab_prevailing_decl): Do not special case weakrefs. * passes.c (rest_of_decl_compilation): Set static flag, too. * symtab.c (dump_symtab_base): Dump weakref. (verify_symtab_base): Sanity check weakrefs. (symtab_make_decl_local): Remove duplicated code. (symtab_alias_ultimate_target): Simplify. * varpool.c (varpool_create_variable_alias): Set weakref flag. * lto-partition.c (get_symbol_class): Simplify weakref handling. (add_symbol_to_partition_1): Likewise. (contained_in_symbol): Likewise. (lto_balanced_map): Likewise. (rename_statics): Drop weakref. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@199971 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/lto-symtab.c | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) (limited to 'gcc/lto-symtab.c') diff --git a/gcc/lto-symtab.c b/gcc/lto-symtab.c index 2b41933c67e..5f0b9716556 100644 --- a/gcc/lto-symtab.c +++ b/gcc/lto-symtab.c @@ -235,9 +235,6 @@ lto_symtab_symbol_p (symtab_node e) { if (!TREE_PUBLIC (e->symbol.decl) && !DECL_EXTERNAL (e->symbol.decl)) return false; - /* weakrefs are really static variables that are made external by a hack. */ - if (lookup_attribute ("weakref", DECL_ATTRIBUTES (e->symbol.decl))) - return false; return symtab_real_symbol_p (e); } @@ -589,6 +586,7 @@ lto_symtab_merge_symbols (void) if (!node->symbol.analyzed && node->symbol.alias_target) { symtab_node tgt = symtab_node_for_asm (node->symbol.alias_target); + gcc_assert (node->symbol.weakref); if (tgt) symtab_resolve_alias (node, tgt); } @@ -617,11 +615,6 @@ lto_symtab_prevailing_decl (tree decl) if (TREE_CODE (decl) == FUNCTION_DECL && DECL_BUILT_IN (decl)) return decl; - /* As an anoying special cases weakrefs are really static variables with - EXTERNAL flag. */ - if (lookup_attribute ("weakref", DECL_ATTRIBUTES (decl))) - return decl; - /* Ensure DECL_ASSEMBLER_NAME will not set assembler name. */ gcc_assert (DECL_ASSEMBLER_NAME_SET_P (decl)); -- cgit v1.2.3
