Subject: target/sparc: Change DisasCompare.c2 to int
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=c8507ebf74fc5991cd822a5a34c8d653a6225a9b;p=qmiga%2Fqemu.git

target/sparc: Change DisasCompare.c2 to int

We don't require c2 to be variable, so emphasize that.
We don't currently require c2 to be non-zero, but that will change.
