Subject: linux-user/sparc: Handle coprocessor disabled trap
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c47d7c87bf1cc164306a6bf51d550e5f10bcca02;p=qemu.git

linux-user/sparc: Handle coprocessor disabled trap

Since qemu does not implement a sparc coprocessor, all such
instructions raise this trap.  Because of that, we never raise
the coprocessor exception trap, which would be vector 0x28.
