Subject: [Qemu-devel] [PULL 10/11] qemu/compiler: Define QEMU_ARTIFICIAL
Date: Mon, 22 Sep 2014 13:57:40 -0700	[thread overview]
Message-ID: <1411419461-24390-11-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1411419461-24390-1-git-send-email-rth@twiddle.net>

The combination of always_inline + artificial allows tiny inline
functions to be written that do not interfere with debugging.
In particular, gdb will not step into an artificial function.

The always_inline attribute was introduced in gcc 4.2,
and the artificial attribute was introduced in gcc 4.3.
