Further details of the new features are as follows:

Generics Phase 1
Release 10.1 includes the first phase of the addition of support for Ada generics to the SPARK language and toolset. This first phase includes support for generic subprograms. Users can now write programs which declare a generic subprogram, then instantiate and call the instantiations. The SPARK toolset has been significantly updated to provide flow analysis and proof of VCs generated from the first phase subset of generics, although analysis of the generic subprogram body itself will be added in the next phase. Two new documents have been added to the user documentation set for generics. “SPARK Generics – A user view” describes a subset of Ada Generics which is defined for SPARK 95 and onwards whilst maintaining the underlying design principles of SPARK. A more concise specification of SPARK generics is given in the “SPARK Generics LRM”. The motivation for incorporating generics into SPARK is – as with Ada – to provide the user with reusable components. In SPARK, these can be implemented and proven once but instantiated many times without requiring the implementation of the component to be re-analysed. The introduction of generics will provide a means, in a future release, to provide more SPARK versions of the Ada libraries, in particular the Ada Container Library.

Dynamic Flow Analyser and VCG Heaps
The main Examiner data structures used by the flow-analyser and the verification-condition generator have been re-implemented so they now extend themselves automatically rather than hitting a capacity limit. This means that the user no longer has to select between two statically-sized versions of the Examiner – spark and megaspark. A new debug option “-debug=t” has been implemented that gives more detail when “-statistics” is also selected. This option currently produces a histogram showing the peak usage of each major data structure.
As a result of the internal changes made in implementing this new feature users should also notice a reduction in the time taken to launch the Examiner.

Unicode characters now allowed in string literals
The Examiner now supports string literals containing Unicode characters. This allows, for example, strings containing umlauts, as in Sausage : constant String := “Thüringer Bratwurst”;

Improved use of types and subtypes in FDL
It is now becoming increasingly common to use other proof systems such as Alt-Ergo (via SPARKBridge), Isabelle and Riposte to discharge SPARK VCs. It can be very beneficial to these proof systems to have richer type information included in the FDL. Consequently, the Examiner has been modified to produce this information.
This change is backward compatible, so the Simplifier will still accept the generated FDL and discharge VCs as before. Other proof systems can make use of this information to significantly narrow the bounds for variables they reason about.

Improvements to Simplifier tactics and performance
The Simplifier includes new deduction rules and tactics for numeric expressions and VCs that arise from loop statements that iterate over an unconstrained array type. These new rules and tactics will give improved performance from the Simplifier when discharging certain types of VCs.

Auto-generation of refinement rules
The Examiner will now generate refinement rules for refined own variables alleviating the need for some user rules. This will benefit users performing proofs involving abstract/refined own variables by allowing more VCs to be discharged automatically.

SPARKBridge
Whilst still an experimental feature, a number of changes have been made to SPARKBridge and support for Victor – a feature that gives access to alternate theorem provers.
- The -solver option for Victor has been extended to allow additional SMT solvers to be used: CVC3, Yices and Z3. Alt-Ergo is still supported and remains the only prover actually shipped with SPARK.
- Victor has been updated to the latest upstream version. The most important new features are support for SMTLIB2 and support for user rules.
- Victor and Alt-Ergo are now shipped and supported for OSX. This expands experimental support for Victor to the main three platforms: Windows, GNU/Linux and OSX.

SPARKClean
A new utility has been added to SPARK to clean out files generated by the SPARK tools. By default this tool simply deletes all vcg, rep, lst, siv, sum, etc. files when invoked without arguments. A user manual for SPARKClean is available with the release that provides full documentation of the options available.

As part of a collaborative development with Esterel Technologies, a new language profile has been added to the Examiner for processing automatically-generated SPARK code produced by Esterel’s KCG code generator for SCADE.

Derived Numeric Types
Definition of numeric types has been made easier in Release 10.0 by the introduction of language and tool support for explicitly derived numeric types.

SPARKBridge preview for Windows

GNATbench 2.5 – February 8, 2011

GNATbench 2.5 introduces both new functionality as well as both enhancements and corrections to existing capabilities. New functionality includes many new source completion proposals for the Code Assist feature, new entities displayed in the Outline view, and many new source code correction proposals for the Quick Fix feature. Performance has been increased as well. These additions and enhancements make development and use even easier and more productive.

GNATbench 2.5 is supported on Eclipse 3.5, Eclipse 3.6, Workbench 3.1 and Workbench 3.2.

1. Source code completion via Code Assist includes the following new capabilities:

    Task entries and accept statements
    Qualified aggregates
    Loop parameters (i.e., loop indexes)
    Components declared in the variant parts of discriminated records
    Entities declared in Ada package Standard
    Discriminants
    Pragmas and attributes, including display of the corresponding documentation
    Instances of generic units are now included in completion proposals
    Generic formal parameters are now supported for completions within the generic unit
    Ada 2005 interface types are now supported. All primitive operations will be offered by the completion, even those coming from multiple inheritance.

In addition to the above new capabilities, existing Code Assist completions have been enhanced:
    When completing “raise” statements, only exception names and packages names (for the sake of their visible exceptions) will be proposed
    When completing variables & parameters, only package names and type names will be proposed

2. New entities are now displayed in the Outline view and the view is more robust even when the source file is changing:

    Generic formal parameters are now displayed
    Nodes for project dependencies, i.e., the “with” clauses, are now displayed

3. Many new proposals have been added to the Auto-Fix feature. (Auto Fix parses error and warning messages from the tools and proposes corresponding source code corrections.)

    New proposals for several different warnings
    New proposals for several different style checks
    Disallowed blank line(s) at end of file
    Disallowed blank space
    References to variables for which a pragma Unreferenced is applied
    Unexpected tilde or percent character in SPARK annotations
    Undefined entities, even if the compiler didn’t find any potential match

4. Miscellaneous improvements have also been incorporated, including the following:

    The editor’s syntax highlighting and formatting actions now support Ada 2012 syntax.
    GNATbench now provides a partial navigation mode available even when files are not yet compiled.
    GNATbench startup time has been significantly reduced. This improvement is especially noticeable when using sources from a remote server.

  • New SPARK2005 language profile is now available. At present, basic Ada2005 features supported include ‘Mod, ‘Machine_Rounding, new reserved words, and the static semantics of “overriding”.
  • New ZombieScope tool that detects dead statements, branches and paths in SPARK code, complementing the capabilities of the Simplifier and POGS.
  • Cross Referencing annotations in GPS.
  • Function return annotations are now treated more like procedure post-conditions, being substituted into the VC hypotheses of the caller thus dramatically improving the effectiveness of the theorem prover.
  • A new output format for POGS designed to be both easier to read and easier to search automatically. It also reflects the results of the new ZombieScope tool.
  • Case checking. New Examiner switch that insists on consistent casing within annotations.
