New Revision: 133506

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=133506
Log:
	* team.c (gomp_thread_start): Don't clear ts.static_trip here.
	* loop.c (gomp_loop_static_start, gomp_loop_dynamic_start): Clear
	ts.static_trip here.
	* work.c (gomp_work_share_start): Don't clear ts.static_trip here.

	* libgomp.h: Include ptrlock.h.
	(struct gomp_work_share): Reshuffle fields.  Add next_alloc,
	next_ws, next_free and inline_ordered_team_ids fields, change
	ordered_team_ids into pointer from flexible array member.
	(struct gomp_team_state): Add last_work_share field, remove
	work_share_generation.
	(struct gomp_team): Remove work_share_lock, generation_mask,
	oldest_live_gen, num_live_gen and init_work_shares fields, add
	work work_share_list_alloc, work_share_list_free and work_share_chunk
	fields.  Change work_shares from pointer to pointers into an array.
	(gomp_new_team): New prototype.
	(gomp_team_start): Change type of last argument.
	(gomp_new_work_share): Removed.
	(gomp_init_work_share, gomp_fini_work_share): New prototypes.
	(gomp_work_share_init_done): New static inline.
	* team.c (gomp_thread_start): Clear ts.last_work_share, don't clear
	ts.work_share_generation.
	(new_team): Removed.
	(gomp_new_team): New function.
	(free_team): Free gomp_work_share blocks chained through next_alloc,
	instead of freeing work_shares and destroying work_share_lock.
	(gomp_team_start): Change last argument from ws to team, don't create
	new team, set ts.work_share to &team->work_shares[0] and clear
	ts.last_work_share.  Don't clear ts.work_share_generation.
	(gomp_team_end): Call gomp_fini_work_share.
	* work.c (gomp_new_work_share): Removed.
	(alloc_work_share, gomp_init_work_share, gomp_fini_work_share): New
	functions.
	(free_work_share): Add team argument.  Call gomp_fini_work_share
	and then either free ws if orphaned, or put it into
	work_share_list_free list of the current team.
	(gomp_work_share_start, gomp_work_share_end,
	gomp_work_share_end_nowait): Rewritten.
	* sections.c (GOMP_sections_start): Call gomp_work_share_init_done
	after gomp_sections_init.  If HAVE_SYNC_BUILTINS, call
	gomp_iter_dynamic_next instead of the _locked variant and don't take
	lock around it, otherwise acquire it before calling
	gomp_iter_dynamic_next_locked.
	(GOMP_sections_next): If HAVE_SYNC_BUILTINS, call
	gomp_iter_dynamic_next instead of the _locked variant and don't take
	lock around it.
	(GOMP_parallel_sections_start): Call gomp_new_team instead of
	gomp_new_work_share.  Call gomp_sections_init on &team->work_shares[0].
	Adjust gomp_team_start caller.
	* loop.c (gomp_loop_static_start, gomp_loop_ordered_static_start): Call
	gomp_work_share_init_done after gomp_loop_init.  Don't unlock ws->lock.
	(gomp_loop_dynamic_start, gomp_loop_guided_start): Call
	gomp_work_share_init_done after gomp_loop_init.  If HAVE_SYNC_BUILTINS,
	don't unlock ws->lock, otherwise lock it.
	(gomp_loop_ordered_dynamic_start, gomp_loop_ordered_guided_start): Call
	gomp_work_share_init_done after gomp_loop_init.  Lock ws->lock.
	(gomp_parallel_loop_start): Call gomp_new_team instead of
	gomp_new_work_share.  Call gomp_loop_init on &team->work_shares[0].
	Adjust gomp_team_start caller.
	* single.c (GOMP_single_start, GOMP_single_copy_start): Call
	gomp_work_share_init_done if gomp_work_share_start returned true.
	Don't unlock ws->lock.
	* parallel.c (gomp_resolve_num_threads): Fix non-HAVE_SYNC_BUILTINS
	case.
	(GOMP_parallel_start): Call gomp_new_team and pass that as last
	argument to gomp_team_start.
	* config/linux/ptrlock.c: New file.
	* config/linux/ptrlock.h: New file.
	* config/posix/ptrlock.c: New file.
	* config/posix/ptrlock.h: New file.
	* Makefile.am (libgomp_la_SOURCES): Add ptrlock.c.
	* Makefile.in: Regenerated.
	* testsuite/Makefile.in: Regenerated.

	* testsuite/libgomp.c++/collapse-1.C (main): Make k private in second
	omp for loop.
