Subject: [PATCH 2/7] Compiler Attributes: use the no-underscores syntax
Date: Fri, 31 Aug 2018 19:05:09 +0200 [thread overview]
Message-ID: <20180831170514.24665-2-miguel.ojeda.sandonis@gmail.com> (raw)
In-Reply-To: <20180831170514.24665-1-miguel.ojeda.sandonis@gmail.com>
The attribute syntax optionally allows to surround attribute names
with "__" in order to avoid collisions with macros of the same name
(see https://gcc.gnu.org/onlinedocs/gcc/Attribute-Syntax.html).
This homogenizes all attributes to use the syntax without underscores.
