* 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. 2011-08-30 Thomas quinot <quinot@adacore.com> * 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. 2011-08-30 Ed Schonberg <schonberg@adacore.com> * 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. 2011-08-30 Robert Dewar <dewar@adacore.com> * 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 git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@178321 138bc75d-0d04-0410-961f-82ee72b054a4
