Subject: The FPU emulator doesn't work properly
Date: Tue, 06 Feb 2001 17:07:58 +0100 [thread overview]
Message-ID: <3A80215E.D13FE590@mips.com> (raw)
I think I have send this patch before, but it hasn't got in to the
archive, apparently.
This is needed in order to get the FPU emulator work properly.
