        the list of global DECLs.

2012-04-02  Gary Dismukes  <dismukes@adacore.com>

        * bindgen.adb (Gen_Ada_Init): When compiling for the AAMP small
        library, where we no longer suppress the Standard_Library,
        generate an empty body rather than the usual generation of
        assignments to imported globals, since those aren't present in

2012-04-02  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch4.adb (Expand_N_Quantified_Expression): Reimplemented.
        The expansion no longer uses the copy of the original QE created
        during analysis.
        * sem.adb (Analyze): Add processing for loop parameter specifications.
        * sem_ch4.adb (Analyze_Quantified_Expression): Reimplemented. The
        routine no longer creates a copy of the original QE. All
        constituents of a QE are now preanalyzed and resolved.
        * sem_ch5.adb (Analyze_Iteration_Scheme): Remove the guard which
        bypasses all processing when the iteration scheme is related to a
        QE. Relovate the code which analyzes loop parameter specifications
        to a separate routine.  (Analyze_Iterator_Specification):
        Preanalyze the iterator name. This action was originally
        done in Analyze_Iteration_Scheme. Update the check which
        detects an iterator specification in the context of a QE.
        (Analyze_Loop_Parameter_Specification): New routine. This
        procedure allows for a stand-alone analysis of a loop parameter
        specification without the need of a parent iteration scheme. Add
        code to update the type of the loop variable when the range
        generates an itype and the context is a QE.
        (Pre_Analyze_Range): Renamed to Preanalyze_Range. Update all references
        to the routine.
        * sem_ch5.ads: Code reformatting.
        (Analyze_Loop_Parameter_Specification): New routine.
        * sem_ch6.adb (Fully_Conformant_Expressions): Detect a case
        when establishing conformance between two QEs utilizing different
        specifications.
        * sem_res.adb (Proper_Current_Scope): New routine.
        (Resolve): Do not resolve a QE as there is nothing to be done now.
        Ignore any loop scopes generated for QEs when detecting an expression
        function as the scopes are cosmetic and do not appear in the tree.
        (Resolve_Quantified_Expression): Removed. All resolution of
        QE constituents is now performed during analysis. This ensures
        that loop variables appearing in array aggregates are properly
        resolved.

2012-04-02  Ed Schonberg  <schonberg@adacore.com>

        * sem_util.adb (Build_Default_Subtype): If the base type is

        of Ada.Tags.Displace.
        * exp_util.adb (Initialized_By_Ctrl_Function): Removed.

        (Is_Source_Object): New routine.
        (Requires_Cleanup_Actions): Detect a case where a source object was
        initialized by another source object, but the expression was rewritten

2012-04-02  Ed Schonberg  <schonberg@adacore.com>

        * sem_res.adb (Resolve_Call): A call to an expression function
        does not freeze if it appears in a different scope from the
        expression function itself. Such calls appear in the generated
        bodies of other expression functions, or in pre/postconditions
        of subsequent subprograms.

2012-04-02  Ed Schonberg  <schonberg@adacore.com>

        * sem_ch12.adb (Analyze_Subprogram_Instantiation): Do not suppress
        style checks, because the subprogram instance itself may contain
        violations of syle rules.
        * style.adb (Missing_Overriding): Check for missing overriding
        indicator on a subprogram instance.

2012-04-02  Hristian Kirtchev  <kirtchev@adacore.com>

        * sem_ch6.adb (Last_Implicit_Declaration): New routine.
        (Process_PPCs): Insert the body of _postconditions after the
        last internally generated declaration. This ensures that actual
        subtypes created for formal parameters are visible and properly
        frozen as _postconditions may reference them.

2012-04-02  Robert Dewar  <dewar@adacore.com>

        * einfo.adb (First_Component_Or_Discriminant) Now applies to
        all types with discriminants, not just records.

        in each project tree. The new implementation use a table based on
        the project name to ensure proper detection of duplicate project
        in aggregate library. A new context is then created to continue
        retrurning duplicate project for aggregate libraries.
