4847 * sem_ch5.adb (Analyze_Iteration_Scheme): Remove the guard which
4848 bypasses all processing when the iteration scheme is related to a
4849 QE. Relovate the code which analyzes loop parameter specifications
4850 to a separate routine. (Analyze_Iterator_Specification):
4851 Preanalyze the iterator name. This action was originally
4852 done in Analyze_Iteration_Scheme. Update the check which
4853 detects an iterator specification in the context of a QE.

4855 procedure allows for a stand-alone analysis of a loop parameter
4856 specification without the need of a parent iteration scheme. Add

4867 (Resolve): Do not resolve a QE as there is nothing to be done now.
4868 Ignore any loop scopes generated for QEs when detecting an expression
4869 function as the scopes are cosmetic and do not appear in the tree.
4870 (Resolve_Quantified_Expression): Removed. All resolution of
4871 QE constituents is now performed during analysis. This ensures
4872 that loop variables appearing in array aggregates are properly
4875 2012-04-02 Ed Schonberg <schonberg@adacore.com>
4877 * sem_util.adb (Build_Default_Subtype): If the base type is
4878 private and its full view is available, use the full view in

4908 initialized by another source object, but the expression was rewritten
4909 as a class-wide conversion of Ada.Tags.Displace.
4910 * exp_util.ads (Is_Displacement_Of_Ctrl_Function_Result): Removed.

4915 * sem_res.adb (Resolve_Call): A call to an expression function
4916 does not freeze if it appears in a different scope from the
4917 expression function itself. Such calls appear in the generated
4918 bodies of other expression functions, or in pre/postconditions
4919 of subsequent subprograms.
4921 2012-04-02 Yannick Moy <moy@adacore.com>

4927 * sem_ch12.adb (Analyze_Subprogram_Instantiation): Do not suppress
4928 style checks, because the subprogram instance itself may contain
4929 violations of syle rules.
4930 * style.adb (Missing_Overriding): Check for missing overriding
4931 indicator on a subprogram instance.
4933 2012-04-02 Hristian Kirtchev <kirtchev@adacore.com>
4935 * sem_ch6.adb (Last_Implicit_Declaration): New routine.
4936 (Process_PPCs): Insert the body of _postconditions after the
4937 last internally generated declaration. This ensures that actual
4938 subtypes created for formal parameters are visible and properly
4939 frozen as _postconditions may reference them.
