2010-10-22 Robert Dewar <dewar@adacore.com> * sem_util.ads, sem_util.adb, sem_aux.ads, sem_aux.adb (Is_Generic_Formal): Moved from Sem_Util to Sem_Aux. 2010-10-22 Ed Schonberg <schonberg@adacore.com> * exp_ch5.adb (Expand_Iterator_Loop): New subprogram, implements new iterator forms over arrays and containers, in loops and quantified expressions. * exp_util.adb (Insert_Actions): include N_Iterator_Specification. * par-ch4.adb (P_Quantified_Expression): Handle iterator specifications. * par-ch5.adb (P_Iterator_Specification): New subprogram. Modify P_Iteration_Scheme to handle both loop forms. * sem.adb: Handle N_Iterator_Specification. * sem_ch5.adb, sem_ch5.ads (Analyze_Iterator_Specification): New subprogram. * sinfo.adb, sinfo.ads: New node N_Iterator_Specification. N_Iteration_Scheme can now include an Iterator_Specification. Ditto for N_Quantified_Expression. * snames.ads-tmpl: Add names Cursor, Element, Element_Type, No_Element, and Previous, to support iterators over predefined containers. * sprint.adb: Handle N_Iterator_Specification.
