2017-04-25 Justin Squirek <squirek@adacore.com> * exp_ch3.adb (Freeze_Type): Add condition to always treat interface types as a partial view of a private type for the generation of invariant procedure bodies. * exp_util.adb, exp_util.ads (Add_Inherited_Invariants): Add a condition to get the Corresponding_Record_Type for concurrent types, add condition to return in the absence of a class in the pragma, remove call to Replace_Type_References, and add call to Replace_References. (Add_Interface_Invariatns), (Add_Parent_Invariants): Modify call to Add_Inherited_Invariants to including the working type T. (Add_Own_Invariants): Remove legacy condition for separate units, remove dispatching for ASIS and save a copy of the expression in the pragma expression. (Build_Invariant_Procedure_Body): Default initalize vars, remove return condition on interfaces, always use the private type for interfaces, and move the processing of types until after the processing of invariants for the full view. (Build_Invariant_Procedure_Declaration): Remove condition to return if an interface type is encountered and add condition to convert the formal parameter to its class-wide counterpart if Work_Typ is abstract. (Replace_Type): Add call to Remove_Controlling_Arguments. (Replace_Type_Ref): Remove class-wide dispatching for the current instance of the type. (Replace_Type_References): Remove parameter "Derived" (Remove_Controlling_Arguments): Created in order to removing the controlliong argument from calls to primitives in the case of the formal parameter being an class-wide abstract type. * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Almost identical to the change made to Freeze_Type in exp_ch3. Add a condition to treat interface types as a partial view. * sem_prag.adb (Analyze_Pragma): Modify parameters in the call to Build_Invariant_Procedure_Declaration to properly generate a "partial" invariant procedure when Typ is an interface. 2017-04-25 Bob Duff <duff@adacore.com> * a-numeri.ads: Go back to using brackets encoding for the Greek letter pi.

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.
