2015-03-02 Javier Miranda <miranda@adacore.com> * exp_ch9.adb (Build_Corresponding_Record): Propagate type invariants to the corresponding record type. * exp_disp.ad[sb] (Set_DT_Position_Value): New subprogram which sets the value of the DTC_Entity associated with a given primitive of a tagged type and propagates the value to the wrapped subprogram. (Set_DTC_Entity_Value): Propagate the DTC value to the wrapped entity. * sem_ch13.adb (Build_Invariant_Procedure): Append the code associated with invariants of progenitors. * sem_ch3.adb (Build_Derived_Record_Type): Inherit type invariants of parents and progenitors. (Process_Full_View): Check hidden inheritance of class-wide type invariants. * sem_ch7.adb (Analyze_Package_Specification): Do not generate the invariant procedure for interface types; build the invariant procedure for tagged types inheriting invariants from their progenitors. * sem_prag.adb (Pragma_Invariant) Allow invariants in interface types but do not build their invariant procedure since their invariants will be propagated to the invariant procedure of types covering the interface. * exp_ch6.adb, exp_disp.adb, sem_ch3.adb, sem_ch7.adb, sem_ch8.adb, sem_disp.adb: Replace all calls to Set_DT_Position by calls to Set_DT_Position_Value.

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.
