Subject: [Qemu-devel] [PATCH v2 18/19] target-mips: fix c.ps.* instructions
Date: Thu, 14 Apr 2011 01:11:13 +0200	[thread overview]
Message-ID: <1302736274-2908-19-git-send-email-aurelien@aurel32.net> (raw)
In-Reply-To: <1302736274-2908-1-git-send-email-aurelien@aurel32.net>

Contrary to cabs.ps.* instructions, c.ps.* should not compare the absolute
value of the operand, but directly the operands.
