TREE_USED and the lto incantation. they never exist to be marked: handle_next_class_ref (tree chain) { const char *name = IDENTIFIER_POINTER (TREE_VALUE (chain)); char *string = (char *) alloca (strlen (name) + 30); sprintf (string, ".objc_class_name_%s", name); #ifdef ASM_DECLARE_UNRESOLVED_REFERENCE ASM_DECLARE_UNRESOLVED_REFERENCE (asm_out_file, string); >>>> this just emits .lazy_reference .objc_class_name_xxxxx #else return ; /* NULL build for targets other than Darwin. */ #endif }
