From 00f91aef2e75977bb03a8091ce6b4d4e46ae8d8f Mon Sep 17 00:00:00 2001 From: charlet Date: Mon, 9 Aug 2004 12:24:25 +0000 Subject: 2004-08-09 Thomas Quinot * g-socket.adb (Abort_Selector): Initialize Buf to prevent valgrind from complaining on potential uninitialized reference. Change calls to GNAT.Sockets.Thin.Is_Socket_In_Set to account for new specification and test explicitly for non-zero return value. * g-socthi.ads (Is_Socket_In_Set): Declare imported function as returning C.int, to avoid using a derived boolean type. * exp_ch5.adb (Make_Tag_Ctrl_Assignments): Use Duplicate_Subexpr_No_Checks in preference to direct use of Remove_Side_Effects and New_Copy_Tree. Clear Comes_From_Source on prefix of 'Size attribute reference. * g-socthi.adb, g-socthi-vms.adb, g-socthi-mingw.adb, g-socthi-vxworks.adb: Change calls to GNAT.Sockets.Thin.Is_Socket_In_Set to account for new specification and test explicitly for non-zero return value. * g-socthi-vms.ads, g-socthi-mingw.ads, g-socthi-vxworks.ads: (Is_Socket_In_Set): Declare imported function as returning C.int, to avoid using a derived boolean type. 2004-08-09 Albert Lee * system-irix-n32.ads: Refine tasking priority constants for IRIX. 2004-08-09 Pascal Obry * gnat_ugn.texi: Document new way to build DLLs on Windows using GCC's -shared option. * mlib-tgt-mingw.adb (Build_Dynamic_Library): Pass GCC's options into Options_2 parameter (options put after object files). 2004-08-09 Olivier Hainque * decl.c (gnat_to_gnu_entity) : Adjust condition to ignore overflows on low and high bounds of an index to also account for differences in signedness between sizetype and gnu_index_subtype. These are as legitimate as the ones caused by a lower TYPE_PRECISION on sizetype. 2004-08-09 Robert Dewar * s-solita.ads, s-solita.adb: Minor reformatting * gnat_rm.texi: Add documentation for pragma Profile (Restricted) Move pragma Restricted_Run_Time, No_Run_Time, Ravenscar to new obsolescent section Add note that No_Implicit_Conditionals does not suppress run time constraint checks. * vms_conv.ads: Minor reformatting * s-secsta.adb: Use SS_Ptr instead of Mark_Id as stack pointer (cleanup and necessary for following change). (Mark): Return new format Mark_Id containing sec stack address (Release): Use sec stack address from Mark_Id avoiding Self call * s-secsta.ads: Define SS_Ptr to be used instead of Mark_Id as stack pointer (cleanup and necessary for following change). Define Mark_Id as record containing address of secondary stack, that way Release does not need to find the stack again, decreasing the number of calls to Self and improving efficiency. * sem_util.ads: Add a ??? comment for Is_Local_Variable_Reference * sem_ch5.adb (Analyze_Case_Statement): Add circuitry to track value of case variable into the individual case branches when possible. * sem_ch11.adb: Minor reformatting * prj.ads: Correct spelling of suffixs * prj-nmsc.adb: Minor reformatting Correct spelling suffixs throughout (also in identifiers) * freeze.adb: Minor spelling correction * exp_ch2.adb: Cleanups to handling of Current_Value (no functional effect). * bld.adb: Correct spelling of suffixs * einfo.adb (Enclosing_Dynamic_Scope): Defend against junk argument 2004-08-09 Ed Schonberg PR ada/15408 * sem_ch7.adb (Install_Private_Declarations): In the body of the package or of a child, private entities are both immediately_visible and not hidden. 2004-08-09 Ed Schonberg * sem_eval.adb (Eval_Integer_Literal): If the context is Any_Integer, there are no range checks on the value of the literal. * exp_ch7.adb (Insert_Actions_In_Scope_Around): If the node being wrapped is the triggering alternative of an asynchronous select, action statements mustbe inserted before the select itself. * sem_attr.adb (Analyze_Attribute, case 'Size): Handle properly the case where the prefix is a protected function call. (Resolve_Attribute, case 'Access): The attribute reference on a subprogram is legal in a generic body if the subprogram is declared elsewhere. 2004-08-09 Vincent Celier * makegpr.adb (Build_Library): Link with g++ if C++ is one of the languages, otherwise building the library may fail with unresolved symbols.
