    GPS: Windows view sort order
    Two new settings have been added to the Windows view: you can now choose whether to show nodes for notebooks that have a single window (the default is still to display the window itself, but not its notebook in this case); and you can choose whether to sort windows alphabetically, or to preserve the order of tabs within the notebooks. When the notebooks are not displayed, and sorting is disabled, the order depends on which window had the keyboard focus last, which provides a convenient way of switching quickly between a few editors among a lot of them.

    Better handling of ‘Length on modular index types
    The translation of the 'Length array attribute has been improved to avoid unecessary conversions when the index type is a modular integer type. This should improve provability whenever 'Length is used on a modular index type in contracts.

    Improved warning for value not referenced
    The wording of two warnings related to values assigned to an object but possibly never referenced has been adjusted to reflect that these values might actually be referenced in some corner cases (namely, components of a controlled object might be referenced during the finalization of that object).

    GPS: GUI enhancements to the Omnisearch
    The Omnisearch feature has received a number of enhancements:

       - A default key shortcut (control-u) brings up the omnisearch
    
       - When bringing up the omnisearch through the key shortcut
         completions start appearing even before anything is typed
         in the entry. This allows, for instance, using the arrow keys
         to select one of the currently open windows.
    
       - The size of the popup window has been increased to take up to
         2/3 of the main window. This is useful when listing directories
         with long names, for instance.
    
       - The highlighting of the fuzzy-matched characters now uses a
         color.
    
       - If the text in the global entry has been manually deleted,
         it no longer reappears next time the search is activated.

    AI12-061 : iterated component associations
    Ada issue AI12-061 introduces a new construct in array aggregates allowing component associations to be parameterized by a loop variable, for example:

      Squares : Array (1 .. 10) of Integer :=
         (for I in 1 .. 10 => I ** 2);
      type Matrix is array
         (Positive range <>, Positive range <>) of Float;
      G : constant Matrix :=
         (for I in 1 .. 4 =>
             (for J in 1 .. 4 =>
                (if I=J then 1.0 else 0.0))); -- Identity matrix
    
    
    The expression in such an association can also be a function that returns a limited type, and the range can be specified by an 'others' choice.

    gnatbind: New elaboration order algorithm
    A new elaboration order algorithm is implemented, which is likely to be friendlier in most cases, especially with existing code that works with other compilers. It has the following useful properties: - Considering the graph of library units, each strongly connected component (SCC) is elaborated together, with no intervening units from other SCCs. In the absence of cycles in this graph, an SCC is a single library unit. If there are cycles, an SCC is a maximal group of units with cyclic dependences. Note that the nodes of this graph are library units, not library items. Cycles among library items are illegal (e.g. two specs cannot mention each other in nonlimited with clauses). Cycles among library units are legal (two packages may be mutually recursive, so long as at least one dependence is via a body. - In particular, this implies that if an SCC contains just a spec and the corresponding body, and nothing else, the body will be elaborated immediately after the spec. This is expected to result in a better elaboration order for most programs, because in this case, a call from outside the library unit cannot get ABE. - The elaboration order chosen is the same in static and dynamic mode. - Pragmas Elaborate_All (explicit and implicit) are ignored. Instead, we behave as if every legal pragma Elaborate_All were present. That is, if it would be legal to have "pragma Elaborate_All(Y);" on X, then we behave as if such a pragma exists, even if it does not.

    More fine-grain placement rules for pragma Annotate
    Previously, if pragma Annotate was placed e.g. at the start of a statement list, it would apply to the whole enclosing construct (e.g. an if statement including all branches and statements). Now it only applies to the range between the beginning of the enclosing statement and the pragma itself. This allows to e.g. apply a pragma Annotate to the condition of an if-statement, but not the other parts of the if-statement. Note that this may require changes to the placement of pragma Annotate in existing code, or more pragma Annotate than before.

    A new trace "Views.No_Transient_Views" has been added. When activated (in .gps/traces.cfg or via the --traceon switch), this prevents the use of "transient" windows for floating views. This is needed mostly for compatibility with the Xming X11 server which does not allow resizing transient windows, and calculates their size wrongly. Another trace "Store_Window_Positions" has been added: this is on by default, and, when switched off, will prevent GPS from saving the size and positions of floating windows.

    Performance improvement when building libraries
    When binding Stand-Alone Libraries, gprbuild no longer gets the time stamps of the sources and object files if they are already known, if the main project is not an aggregate project.

    Indirect call results now show original name
    When CodePeer produces a message about an indirect or dispatching call, it used to identify the result by "Indirect_Call'Result." Now it uses the actual name used in the call, such as "P.all'Result" if it is a call through an access-to-subprogram value P, or "Prim_Op'Result" if it is a dispatching call of a primitive operation Prim_Op.

    Improve posting of SPARK violations
    SPARK violations are now posted on the entity that is not in SPARK rather than on the entity that will result not to be in SPARK for this violation. This is done for formal parameters of a function, return types of a function and indexes of an array.

    More precise handling of aliasing
    CodePeer handles aliasing in a more precise way. This includes detecting conditions always true or false in more cases when using complex expressions in conditions, for instance expressions involving aliased variables, and more precise handling of aliasing in a per-file mode when aliased variables are declared in a module imported by the file being analyzed.

    New switch—no-sal-binding
    A new switch --no-sal-binding is added to gprbuild. When this switch is used gprbuild will not rebind Stand-Alone Libraries, it will reuse the files created during a previous build of the SAL, and will fail if there are missing files.

    Better display of long ranges
    When displaying very long ranges (e.g. for large floating point values), CodePeer would truncate the range completely and instead display a "[...]" only. CodePeer now displays a truncated value for the two values of the range.

    Efficient 64-bit integer multiplication on x86-64
    The compiler now generates the same efficient 64-bit integer multiplication on x86-64 when overflow checking is enabled as when it is disabled.

    New switch -unconstrained-fpt-overflow
    Overflow detection on unconstrained floating point types previously required the use of the compiler switch -gnateF to be enabled. This can now be enabled more easily via the codepeer switch -unconstrained-fpt-overflow which is also enabled by default at -level 4.

    Improved debugger module loading speed on VxWorks
    Loading modules from the debugger on VxWorks targets is now significantly faster. This enhancement assumes that the file location where the module is stored is the same for the target server as for the debugger. For users who run the debugger and the target server on different hosts, the debugger can be made to transmit the contents of the module to the target server using the following command: "set wtx load-from-gdb".

    More convenient support for Coq interactive prover
    Previously, to be able to use the Coq interactive prover with SPARK, it was required to create a why3.conf file with the appropriate configuration. Now, SPARK comes with the suitable configuration already included, and this extra step is not needed any more. The Coq prover still needs to be installed separately.

    New pragma/aspect Secondary_Stack_Size
    The new GNAT pragma and aspect Secondary_Stack_Size allows users to specify the size of the secondary stack individually for each task type in bytes where fixed secondary stack allocation is used. This allocation scheme is used on bare board and Ravenscar run- times which by default allocate a fixed percentage of the primary stack for the secondary stack.

    GPS: Breakpoints view can be displayed anywhere
    Since we can now set breakpoints even when no debugger is running, it is also useful to edit them outside of the Debug perspective.

    New assertion policy Suppressible
    Pragma Assertion_Policy can now specify policy Suppressible. This policy is equivalent to Ignore when compilation switch -gnatp is in effect, otherwise it behaves the same as policy Check.
