From 14f8ba9ad1d587528208b9f759849333a19918d8 Mon Sep 17 00:00:00 2001 From: Ed Schonberg Date: Tue, 29 May 2018 09:41:45 +0000 Subject: [PATCH] [Ada] Unnesting: exclude selected components whose prefix carry no type 2018-05-29 Ed Schonberg gcc/ada/ * exp_unst.adb (Visit_Node): Exclude selected components whose prefix carry no type. Such selected components appear in unit names that are child units, both in the specification and possibly in an end label for the unit, and they do not contain any relevant uplevel references.
