Subject: [PATCH 3/5] gensel: controlling expression must be lvalue converted
Date: Fri, 19 Jun 2020 17:02:58 +0200 [thread overview]
Message-ID: <20200619150300.63695-4-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20200619150300.63695-1-luc.vanoostenryck@gmail.com>
Following the resolution of DR481, the controlling expression
of a generic selection must be lvalue converted. In other words,
the qualifiers must be ignored.
