SPARK RM now allow the property No_Caching on volatile types, to indicate that they should be considered volatile for compilation, but not by GNATprove's analysis. gcc/ada/ * contracts.adb (Add_Contract_Item): Allow No_Caching on types. (Check_Type_Or_Object_External_Properties): Check No_Caching. Check that non-effectively volatile types does not contain an effectively volatile component (instead of just a volatile component). (Analyze_Object_Contract): Remove shared checking of No_Caching. * sem_prag.adb (Analyze_External_Property_In_Decl_Part): Adapt checking of No_Caching for types. (Analyze_Pragma): Allow No_Caching on types. * sem_util.adb (Has_Effectively_Volatile_Component): New query function. (Is_Effectively_Volatile): Type with Volatile and No_Caching is not effectively volatile. (No_Caching_Enabled): Remove assertion to apply to all entities. * sem_util.ads: Same.
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.
