Subject: [PATCH 06/17] bad-goto: simplify testing of undeclared labels
Date: Mon, 13 Apr 2020 18:15:54 +0200 [thread overview]
Message-ID: <20200413161605.95900-7-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20200413161605.95900-1-luc.vanoostenryck@gmail.com>
There is no need to do a lookup: checking if the label's
symbol is in the NS_LABEL namespace and is lacking an
associated statement is enough and much simpler.
