Re: [Qemu-devel] Compile errors on Solaris for qemu 0.8.2

["Leonardo E. Reiter" <lreiter@win4lin.com>]

I ran into this myself yesterday.  I couldn't figure out a definitive
answer, because I am no expert on the SPARC architecture, but it appears
that at least on an UltraSparc IIi machine from a few years ago, the
"sparc V9" instructions are supported.  However, the gcc by default
doesn't define __sparc_v9__ on that architecture.  There are some -m
flags that can be passed to gcc (like multisparc, etc.), but I'm not
sure for what host machines they are appropriate exactly.  Perhaps the
SPARC experts on the list can comment more, but in the meantime, the
following simple (but likely incorrect) patch worked fine for me:
