Subject: [PATCH 3/8] remove test on initial phi->ident
Date: Thu, 13 Apr 2017 18:55:46 +0200	[thread overview]
Message-ID: <20170413165551.2785-4-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20170413165551.2785-1-luc.vanoostenryck@gmail.com>

The code used to be like:
 	pseudo_t phi = alloc_phi(...);
	phi->ident = phi->ident ? : ...
but this new allocated phi can never have an identifier.

Change this by removing the test and directly assigning the
other part of the conditional.
