5031 * sem_ch5.adb (Analyze_Iteration_Scheme): Remove the guard which
5032 bypasses all processing when the iteration scheme is related to a
5033 QE. Relovate the code which analyzes loop parameter specifications
5034 to a separate routine. (Analyze_Iterator_Specification):
5035 Preanalyze the iterator name. This action was originally
5036 done in Analyze_Iteration_Scheme. Update the check which
5037 detects an iterator specification in the context of a QE.
5038 (Analyze_Loop_Parameter_Specification): New routine. This
5039 procedure allows for a stand-alone analysis of a loop parameter
5040 specification without the need of a parent iteration scheme. Add
5041 code to update the type of the loop variable when the range
5042 generates an itype and the context is a QE.

5052 Ignore any loop scopes generated for QEs when detecting an expression
5053 function as the scopes are cosmetic and do not appear in the tree.
5054 (Resolve_Quantified_Expression): Removed. All resolution of
5055 QE constituents is now performed during analysis. This ensures
5056 that loop variables appearing in array aggregates are properly
5059 2012-04-02 Ed Schonberg <schonberg@adacore.com>
5061 * sem_util.adb (Build_Default_Subtype): If the base type is

7219 the project name to ensure proper detection of duplicate project
7220 in aggregate library. A new context is then created to continue
7221 retrurning duplicate project for aggregate libraries.
