(class Initialize_lock): Rewrite as child of Once. * gold-threads.cc (class Once_initialize): Define. (once_pointer_control): New static variable. (once_pointer, once_arg): New static variables. (c_run_once): New static function. (Once::Once, Once::run_once, Once::internal_run): New functions. (class Initialize_lock_once): Remove. (initialize_lock_control): Remove. (initialize_lock_pointer): Remove. (initialize_lock_once): Remove. (Initialize_lock::Initialize_lock): Move to gold-threads.h. (Initialize_lock::initialize): Rewrite. (Initialize_lock::do_run_once): New function. * archive.cc (Archive::interpret_header): Only clear name if it is not already empty. * fileread.cc: Include "gold-threads.h" (file_counts_lock): New static variable. (file_counts_initialize_lock): Likewise. (File_read::release): Only increment counts when using --stats. Use a lock around the increment. * parameters.cc (class Set_parameters_target_once): Define. (set_parameters_target_once): New static variable. (Parameters::Parameters): Move here from parameters.h. (Parameters::set_target): Rewrite. (Parameters::set_target_once): New function. (Parameters::clear_target): Move here and rewrite. * parameters.h (class Parameters): Update declarations. Add set_parameters_target_once_ field. (Parameters::Parameters): Move to parameters.cc. (Parameters::clear_target): Likewise. * readsyms.cc (Read_symbols::do_group): Create a Start_group task. (Start_group::~Start_group): New function. (Start_group::is_runnable): New function. (Start_group::locks, Start_group::run): New functions. (Finish_group::run): Change saw_undefined to size_t. * readsyms.h (class Start_group): Define. (class Finish_group): Change saw_undefined_ field to size_t. (Finish_group::Finish_group): Remove saw_undefined and this_blocker parameters. Change all callers. (Finish_group::set_saw_undefined): New function. (Finish_group::set_blocker): New function. * symtab.h (class Symbol_table): Change saw_undefined to return size_t. Change saw_undefined_ field to size_t. * target-select.cc (Set_target_once::do_run_once): New function. (Target_selector::Target_selector): Initialize set_target_once_ field. Don't initialize lock_ and initialize_lock_ fields. (Target_selector::instantiate_target): Rewrite. (Target_selector::set_target): New function. * target-select.h (class Set_target_once): Define. (class Target_selector): Update declarations. Make Set_target_once a friend. Remove lock_ and initialize_lock_ fields. Add set_target_once_ field. --- gold/fileread.h | 13 ++++++------- 1 file changed, 6 insertions(+), 7 deletions(-) (limited to 'gold/fileread.h') diff --git a/gold/fileread.h b/gold/fileread.h index 47c8e0f..5aac7ad 100644 --- a/gold/fileread.h +++ b/gold/fileread.h @@ -1,6 +1,6 @@ // fileread.h -- read files for gold -*- C++ -*- -// Copyright 2006, 2007, 2008, 2009 Free Software Foundation, Inc. +// Copyright 2006, 2007, 2008, 2009, 2010 Free Software Foundation, Inc. // Written by Ian Lance Taylor . // This file is part of gold. @@ -218,16 +218,15 @@ class File_read File_read(const File_read&); File_read& operator=(const File_read&); - // Total bytes mapped into memory during the link.
