Subject: [Qemu-devel] [PATCH v4] ipmi: Fix macro issues
Date: Fri, 31 Mar 2017 09:33:03 -0500 [thread overview]
Message-ID: <1490970783-29231-1-git-send-email-minyard@acm.org> (raw)
From: Corey Minyard <cminyard@mvista.com>
Macro parameters should almost always have () around them when used.
llvm reported an error on this.
Remove redundant parenthesis and put parenthesis around the entire
macros with assignments in case they are used in an expression.
The macros were doing ((v) & 1) for a binary input, but that only works
if v == 0 or if v & 1. Changed to !!(v) so they work for all values.
Remove some unused macros.
Reported in https://bugs.launchpad.net/bugs/1651167
