    Improve type name matching in gnatdbg
    Both gnatdbg.printers.PrettyPrinter and gnatdbg.generics.Match.TypeName have been enhanced to be able to match pretty GDB type names (i.e. the result of `str(gdb_type)`) in addition to their raw names (`gdb_type.name` or `gdb_type.tag`).

    PolyORB: iac: ignore pragma javaPackage
    The IDL-to-Ada compiler iac now ignores pragma javaPackage. This is a convenience for those also using idlj (idl-to-java), because idlj recognizes that pragma.

    Better subprogram input annotations
    If a subprogram takes one or more components of one global object as inputs (as opposed to reading the object as a whole), CodePeer formerly omitted these from the list of inputs in the annotations generated for the subprogram. Now the global object is listed as an input. This means that if either or both of Some_Record.Field_1 and Some_Record.Field2 are global inputs to a subprogram, then Some_Record will be listed as an input.

    More accurate C binding for enumerals and constants
    The C and C++ bindings generated by means of the -fdump-ada-spec option can now use a more accurate Ada type for enumeral types and support the declaration of const-qualified variables.

  • GNAT Pro | GPRbuild
    Jul 27th, 2017

    Directory of gprbuild added to the PATH
    When gprbuild is invoked, it now adds the directory of its executable to PATH, so that gprconfig can be found when using auto-configuration.

    Jul 24th, 2017

    Efficient array reset for all elementary types
    The compiler now generates efficient code to reset a large array of any elementary component type to zeros, or an equivalent value for the component type, so now includes arrays of floating-point and access values instead of being limited to arrays with a discrete component type.

  • SPARK Pro
    Jul 21st, 2017

    Conversion between arrays with different components
    GNATprove now supports conversion between array types with different component types as long as the component types are statically matching (as allowed by the Ada RM).

    Pragma Ada_2020
    Pragma Ada_2020 can be used to enable Ada 2020 features that have been implemented in GNAT. Ada_2020 is a configuration pragma. This is in addition to the -gnat2020 command-line switch.

    Automatically unroll static loops w/o loop invariant
    Loop invariants are a known difficulty for beginners to use formal program verification. At the same time, many loops written in exercises and to familiarize oneself with the technology have static bounds and a small range. This enhancement implements loop unrolling for such loops with static bounds and not too many iterations (current threshold is at 20 iterations maximum). This way, simple loops with static bounds are proved without requiring a loop invariant. We let the user decide if she wants to use this feature or not: - by only unrolling FOR loops that have no loop (in)variant. - by disabling this feature when the switch --no-loop-unrolling is used.

    No inlining of subprograms visible to child packages
    GNATprove no longer inlines subprograms declared in private parts of package specifications as part of its "Contextual Analysis of Subprograms without Contracts" feature (which is documented in the SPARK User's Gude). Such inlining could be confusing for the users, because the same code could be provable if located in a package body, but not provable if located in a child package. As a result a spurious warning of the form "analyzing unreferenced procedure" for subprograms visible to child packages is no longer emitted.

  • GNAT Pro
    Jun 28th, 2017

    New gnatcheck rule Too_Many_Dependencies
    This rule flags a library item or a subunit that immediately depends on more than N library units (where N is a rule parameter). In the case of a dependency on a child unit, implicit and explicit dependencies on the child unit's parents are not counted.

  • GNAT Pro
    Jun 23rd, 2017

    Direct conversion from unsigned subtype to FP type
    On 32-bit RISC platforms, the compiler now generates a direct conversion from a 32-bit unsigned subtype of a 64-bit base type to a floating-point type instead of calling a dedicated routine.

    Enable multiprocesing by default in IDEs
    When interacting with GNATprove inside GPS or GNATbench, it is desirable that the analysis uses all available cores to go as fast as possible. This is now achieved by selecting by default the "multiprocessing" mode with -j0. The user can always revert that in the analysis/proof panel opened.

    Jun 15th, 2017

    Refine warning on redundant comparison to True
    In many cases, comparing the value of an expression to True is a matter of preference to decide what is clearer. Thus, in such cases the use of -gnatwr may lead to spurious warnings. This is revised: GNAT now only warns on comparisons with True when the expression being compared is an object name or a simple expression involving an operator.

  • SPARK Pro
    May 31st, 2017

    Improve message for overridden subprograms
    When an overriding subprogram has more effects on globals variables than the overridden subprogram, GNATprove will report an error message. We have now improved this message making more explicit the underlying issue and we have reworded the case when these effects are through access types (i.e. pointers).

  • CodePeer
    May 31st, 2017

    Ada syntax is used for addresses in messages
    When codepeer generates a message which refers to the address of some entity named Foo, the message text is now "Foo'Address" in cases where previous versions of CodePeer generated "&Foo".

  • SPARK Pro
    May 11th, 2017

    Added preconditions to standard numerical functions
    Preconditions have been added to functions from the standard numerical package Ada.Numerics.Generic_Elementary_Functions, in cases that may lead to Numerics.Argument_Error or Constraint_Error when called on actual parameters that are not suitable, like a negative input for Sqrt. This ensures that GNATprove generates corresponding precondition checks when such functions are called.

    Protect against unsound function contracts
    When a function has an inconsistent contract (a contract which cannot hold for some inputs), GNATprove used to generate an unsound axiom which may then allow to prove anything in a caller of such a function, and so, even if the function is always called on 'valid' inputs, that is, inputs on which the contract holds. Though this behavior is expected with a proof technology such as SPARK, it used to come as a surprise to some users. We now avoid generating unsound axioms as much as possible by introducing guards for function axioms which are only assumed to hold on actually used values. Note that there are still cases where an unsound axiom will be generated (functions called in type invariants / type predicates, in primitive equalities of record types, or sometimes in user written quantified expressions). As a consequence, having inconsistent contracts on functions is still a bad usage of SPARK, and users should avoid it as much as possible. Also, this new 'safer' translation can sometimes impact proof capabilities. Thus, we provide an advanced switch --no-axiom-guard to disable it.
