Simplify many operations. * a-convec.ads, a-convec.adb: Change the code to be more similar to a-coinve. * a-finali.ads, a-finali.adb: Expose the "null"-ness of the operations.

E.g. use RAII to make incrementing/decrementing of the counts more concise. * a-contai.adb: New package body, implementing the above. * a-convec.ads, a-convec.adb: Use tampering check machinery in Ada.Containers. Disable all checking code when checks are suppressed. Simplify many of the operations. Implement "&" in terms of Append, rather than "by hand". Remove: function "=" (L, R : Elements_Array) return Boolean is abstract; so we can call the predefined "=" on Elements_Array. For "=" on Vectors: Previously, we returned True immediately if Left'Address = Right'Address. That seems like a non-optimization ("if X = X" is unusual), so removed that. Simplify by using slice comparison ("=" on Element_Array will automatically call "=" on the components, even if user defined). 2015-10-16 Ed Schonberg * sem_ch13.adb (Chek_Record_Representation_Clause): When iterating over components, skip anonymous subtypes created for constrained array components. 2015-10-16 Eric Botcazou * a-tags.ads (Parent_Size): Remove obsolete pragma Export. * s-finmas.ads (Header_Offset): Delete. * s-finmas.adb (Header_Offset): Likewise.

(Force_Boolean_Evaluation): New routine. 2015-10-16 Bob Duff * sem_util.adb (Has_Discrim_Dep_Array): Remove this function, and the call. No longer needed now that the back end can handle such things. Should result in further speedups in some cases. 2015-10-16 Ed Schonberg * sem_ch13.adb (Build_Predicate_Functions): If expression for predicate is side-effect free, indicate that the predicate function is pure, to allow for optimization of redundant predicate checks. 2015-10-16 Arnaud Charlet * checks.adb: Fix typo. * s-osinte-linux.ads: Add header. * projects.texi: Removed, no longer used. * gcc-interface/Make-lang.in: Update dependencies * s-multip.adb: Minor: fix header. * sem_ch3.adb, exp_ch7.adb, g-dirope.ads, sinfo.ads, types.ads, a-textio.adb, s-exctra.adb, ali.adb, back_end.ads, exp_intr.adb, a-tigeli.adb, exp_ch3.adb, s-os_lib.ads: Remove further references to .NET. * gnatlink.adb, opt.ads, exp_aggr.adb, s-solita.adb: Minor comment updates. 2015-10-16 Gary Dismukes * exp_ch9.adb (Build_Simple_Entry_Call): Set_Is_Internal on the temporary object used for a by-copy entry parameter, to ensure that the object doesn't get its No_Initialization flag reset later in Default_Initialize_Object.

The names of the formals and the defaults can differ between the two operations when they are operations of a formal derived type. 2015-05-22 Bob Duff * a-convec.ads, a-convec.adb (Append): Check for fast path. Split out slow path into separate procedure. Inline Append. Fast path now avoids calling Insert. (Finalize): Do the busy checking last, so the container gets emptied.

(Install_Body): In the presence of actuals that incomplete types from a limited view, the instance body cannot be placed after the declaration because full views have not been seen yet. Any use of the non-limited views in the instance body requires the presence of a regular with_clause in the enclosing unit, and will fail if this with_clause is missing. We place the instance body at the beginning of the enclosing body, which is the unit being compiled, and ensure that freeze nodes for the full views of the incomplete types appear before the instance. 2015-05-22 Pascal Obry * makeutl.ads, prj-conf.adb, prj-nmsc.adb, prj.ads (In_Place_Option): Removed.

This is used as a common ground to feed both ttypes values and the GNAT tree nodes for the standard floating point types. * set_targ.adb (Long_Double_Index): The index at which "long double" gets registered in the FPT_Mode_Table. This is useful to know whether we have a "long double" available at all and get at it's characteristics without having to search the FPT_Mode_Table when we need to decide which C type should be used as the basis for Long_Long_Float in Ada.
