[Qemu-devel] [PATCH 0/3] mips setcond and movcond

[Richard Henderson <rth@twiddle.net>]

It has been compile tested, but nothing else.

I'm moderately surprised at the implementation of brcond.  It's
missing the BLTZ, BLEZ, BGTZ, BGEZ branches.  It's could be 
improved with the SLTI and SLTIU insns used here with setcond.

Indeed, I suspect that a good implementation of brcond would be
to take care of the cases implementable directly by branches,
and then call into setcond to take care of the rest.  I don't
plan to do that.
