2017-04-25 Ed Schonberg <schonberg@adacore.com> * freeze.adb (Check_Expression_Function): Do not check for the use of deferred constants if the freezing of the expression function is triggered by its generated body, rather than a premature use. 2017-04-25 Javier Miranda <miranda@adacore.com> * exp_attr.adb (Rewrite_Stream_Proc_Call): Handle subtypes of private types when performing the view conversion. 2017-04-25 Hristian Kirtchev <kirtchev@adacore.com> * exp_ch3.adb (Freeze_Type): Signal the DIC body is created for the purposes of freezing. * exp_util.adb Update the documentation and structure of the type map used in class-wide semantics of assertion expressions.

This patch introduces an exception to this general rule: the declaration of constants and variables located in Expression_With_Action nodes. (Copy_Itype_With_Replacement): Renamed as Copy_Entity_With_Replacement. (In_Map): New subprogram. (Visit_Entity): New subprogram.

PR c++/80016 reports an issue with bizarre underlined range for a complicated expression. The root cause for the incorrect *starting* location of that range is that alignof and sizeof expressions currently have start == finish == caret at the opening parenthesis of the expression.
