Subject: [PATCH 2/2] powerpc/mpc85xx: only emulate the unimplemented FP instructions on corenet64
Date: Tue, 16 Jul 2013 19:57:16 +0800 [thread overview]
Message-ID: <1373975836-11928-3-git-send-email-haokexin@gmail.com> (raw)
In-Reply-To: <1373975836-11928-1-git-send-email-haokexin@gmail.com>
We have split the math emulation into two parts. This makes it
possible to just emulate the unimplemented floating point instructions
on these boards.
