2017-04-25 Hristian Kirtchev <kirtchev@adacore.com> * sem_util.adb (Is_Post_State): A reference to a generic in out parameter is considered a change in the post-state of a subprogram. 2017-04-25 Ed Schonberg <schonberg@adacore.com> * sem_ch12.adb (Load_Parent_Of_Generic); When retrieving the declaration of a subprogram instance within its wrapper package, skip over null statements that may result from the rewriting of ignored pragmas. 2017-04-25 Ed Schonberg <schonberg@adacore.com> * exp_attr.adb (Expand_Attribute_Reference, case 'Read): If the type is an unchecked_union, replace the attribute with a Raise_Program_Error (rather than inserting such before the attribute reference) to handle properly the case where we are processing a component of a larger record, and we need to prevent further expansion for the unchecked union. (Expand_Attribute_Reference, case 'Write): If the type is an unchecked_union, check whether enclosing scope is a Write subprogram. Replace attribute with a Raise_Program_Error if the discriminants of the unchecked_union type have not default values because such a use is erroneous.. 2017-04-25 Tristan Gingold <gingold@adacore.com> * exp_ch9.adb (Expand_N_Task_Type_Declaration): Add relative_deadline to task record on edf profile.

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.
