Subject: [PATCH 0/2] powerpc/math-emu: two patches for the emulation of the FPU unimplemented instructions
Date: Thu, 11 Jul 2013 20:21:53 +0800 [thread overview]
Message-ID: <1373545315-9219-1-git-send-email-haokexin@gmail.com> (raw)
These two patches are for the emulation of the FPU unimplemented instructions.
The first is just a bit optimization for the FPU state flush.
The second is requested by Scott.
Kevin Hao (2):
powerpc/math-emu: move the flush FPU state function into do_mathemu
powerpc/math-emu: keep track of the instructions unimplemented by FPU
