This patch fixes a spurious visibility error on a dispatching call to a subprogram with a classwide precondition, when the call qppears in the same declarative part as the subprogram declaration itself. 2019-08-20 Ed Schonberg <schonberg@adacore.com> gcc/ada/ * exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When a dispatching call tp a subprogram with a class-wide precondition occurrs in the same declarative part as the ancestor subprogram being called, the`expression for the precondition has not been analyzed yet. Such a call may appear, e.g. in an expression function. In that case, the replacement of formals by actuals in the call cannot use the formal entities of the subprogram being called, and the occurrence of the formals in the expression must be located by name (Chars fields) as would be done at a later freeze point, when the expression is resolved in the context of the subprogram itself. gcc/testsuite/ * gnat.dg/tagged5.adb, gnat.dg/tagged5.ads: New testcase.
