Subject: [Qemu-devel] [PATCH 2/3] mips: Tweak location of ';' in macros
Date: Thu, 30 Nov 2017 07:41:58 -0600 [thread overview]
Message-ID: <20171130134159.9697-3-eblake@redhat.com> (raw)
In-Reply-To: <20171130134159.9697-1-eblake@redhat.com>
It is more typical to provide the ';' by the caller of a macro
than to embed it in the macro itself; this is because syntax
highlight engines can get confused if a macro is called without
a semicolon before the closing '}'.
