From 79a8810221ee9ea96c4e5a5817afb88f22ea698c Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Thu, 28 Jul 2005 01:07:41 -0700 Subject: [PATCH] alpha: fix "statement with no effect" warnings Apparently gcc 4.0 complains about "({ 0; });", which leads to -Werror breakage in one of the alpha oprofile modules. One might could argue that this is a gcc bug, in that statement-expressions should be considered to be function-like rather than statement-like for the purposes of this warning. But it's just as easy to use an inline function in the first place, side-stepping the issue.
