	* s-taskin.ads (Common_ATCB): Add field domain which contains the
	dispatching domain to which the task belongs.
	* s-taskin.adb (Initialize): Create the default system dispatching
	domain and make the environment task part of it.
	* s-mudido.ads: Add this new spec for standard Ada 2012 package
	Ada.Multiprocessors.Dispatching_Domains.
	* s-mudido.adb: Add this new body for targets not supporting
	dispatching domains.
	* s-mudido-affinity.adb: Add this new body for targets supporting
	dispatching domains setting the affinity to a CPU set.
	* bindgen.adb (Dispatching_Domain_Used, Check_Dispatching_Domains_Used,
	Gen_Adainit): When package System.Multiprocessors.Dispatching_Domains
	is used we call the procedure to signal that when we are about to call
	the main subprogram no new dispatching domain can be created.
	(Check_File_In_Partition): Factor out the common functionality used by
	Check_System_Restrictions_Used and Check_Dispatching_Domains_Used.
	* s-tassta.adb (Create_Task): Tasks inherit the dispatching domain of
	their activators.
	* s-taprop.ads (Set_Task_Affinity): Add this new procedure to set task
	affinities.
	* s-taprop-dummy.adb, s-taprop-hpux-dce.adb, s-taprop-irix.adb,
	s-taprop-posix.adb, s-taprop-tru64.adb, s-taprop-vms.adb
	(Set_Task_Affinity): Dummy null body for these targets not supporting
	task affinities.
	s-taprop-linux.adb, s-taprop-mingw.adb, s-taprop-solaris.adb,
	s-taprop-vxworks.adb (Create_Task, Enter_Task, Initialize): Handle
	dispatching domains and set the affinity of the environment task.
	(Set_Task_Affinity): Procedure that uses the underlying CPU set
	functionality to handle dispatching domains, pragma CPU and Task_Info.
	s-winext.ads (SetThreadAffinityMask): Import this function needed to
	set CPU masks.
	* s-osinte-solaris.ads (psetit_t, pset_create, pset_assign, pset_bind):
	Import the functionality to handle CPU set affinities.
	* affinity.c: New file.
	* s-osinte-vxworks.ads, s-vxwext.ads, s-vxwext-kernel.ads,
	s-vxwext-rtp.ads (taskMaskAffinitySet): Add this new spec for setting
	affinity masks.
	* s-vxwext.adb, s-vxwext-kernel.adb, s-vxwext-rtp.adb
	(taskMaskAffinitySet): Body returning an error indicating that task
	affinities are not supported.
	Makefile.rtl: Indicate that s-mudido is part of libgnarl.
	* gcc-interface/Makefile.in (LIBGNAT_TARGET_PAIRS for VxWorks SMP,
	Solaris, Windows, and {x86,PowerPC, ia64,x86_64} Linux): Use the
	s-mudido-affinity.adb body which supports task affinities.

	* sem_ch13.adb: Minor reformatting.

2011-08-30  Vincent Celier  <celier@adacore.com>

	* vms_conv.adb (Process_Argument): When the qualifier
	/UNCHECKED_SHARED_LIB_IMPORTS is for GNAT COMPILE, do not put the
	corresponding switch --unchecked-shared-lib-imports after -cargs, as it
	is for gnatmake, not for the compiler.

	* sem_ch4.adb (Analyze_Quantified_Expression): Analyze iterator
	specification and condition only in Semantics_Only mode. Otherwise the
	analysis is done after expression has been rewritten as loop.
	* sem_ch5.adb (Analyze_Iterator_Specification): Always generate a
	temporary for the iterator name (the domain of iteration) because it
	may need finalization actions and these must be generated outside of
	the loop.
	* sem_res.adb (Resolve_Quantified_Expression): Resolve only in
	Semantic_Only mode.
	* exp_ch4.adb (Expand_Quantified_Expression): Analyze and resolve once
	rewritten as loop.
	* exp_ch5.adb (Expand_Iterator_Loop): Code clean-up, now that the
	iterator is always an expression.

	* par-ch4.adb (P_Unparen_Cond_Case_Quant_Expression): New function
	(P_Expression_If_OK): New spec checks parens
	(P_Expression_Or_Range_Attribute_If_OK): New spec checks parens
	* par.adb (P_Expression_If_OK): New spec checks parens
	(P_Expression_Or_Range_Attribute_If_OK): New spec checks parens
