2014-07-30 Ed Schonberg <schonberg@adacore.com> * a-chtgop.ads, a-chtgop.adb (Delete_Node_At_Index): New subprogram, used by all versions of hashed sets, to delete a node whose element has been improperly updated through a Reference_ Preserving key. * a-cohase.adb: Remove Delete_Node, use new common procedure Delete_Node_At_Index. * a-cihase.ads: Add Reference_Control_Type to package Generic_Keys. * a-cihase.adb: Add Adjust and Finalize routines for Reference_Control_Type. (Reference_Preserving_Key): Build aggregate for Reference_Control_Type 2014-07-30 Yannick Moy <moy@adacore.com> * checks.adb, checks.ads (Determine_Range_R): New procedure to determine the possible range of a floating-point expression. 2014-07-30 Ed Schonberg <schonberg@adacore.com> * a-cborse.ads: Add Reference_Control_Type to package Generic_Keys. * a-cborse.adb: Add Adjust and Finalize routines for Reference_Control_Type. (Reference_Preserving_Key): Build aggregate for Reference_Control_Type. (Delete): Check for tampering, and raise Program_Error (not Constraint_Error) when attempting to delete an element not in the set. (Insert): Ditto. 2014-07-30 Bob Duff <duff@adacore.com> * a-elchha.adb, a-except-2005.adb, a-except.adb, a-exexda.adb, * a-exextr.adb, a-exstat.adb, exp_intr.ads, s-tassta.adb: Exception_Information is used to produce useful debugging information for the programmer. However, it was also used to implement the stream attributes for type Exception_Occurrence. The latter requires a stable and portable interface, which meant that we couldn't include a symbolic traceback. A separate set of routines was used to provide symbolic tracebacks under program control (i.e. not automatically). The goal of this ticket is to provide such automatic tracebacks, so the change here is to split the two functionalities: Exception_Information gives the maximally useful information for debugging (i.e. it now includes a symbolic traceback when a decorator is set, and it can be improved freely in the future without disturbing streaming). Untailored_Exception_Information always uses hexadecimal addresses in the traceback, has a stable and portable output, and is now used for streaming. 2014-07-30 Eric Botcazou <ebotcazou@adacore.com> * exp_aggr.adb (Expand_Array_Aggregate): Add missing test on the target of the assignment to find out whether it can be directly done by the back-end. * exp_util.adb (Is_Possibly_Unaligned_Slice): Remove obscure test.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
