[Qemu-devel] [PATCH 00/17] target-openrisc improvements

[Richard Henderson <rth@twiddle.net>]

This is a refresh of a branch I worked on in February, but I don't
believe was ever posted.  I'm doing so now in order to flush my set
of uncommitted branches.

The openrisc target is in terrible shape and, as far as I can tell
from the opencores mailing list, no one uses it.  The fact that it's
missing so many of the instructions in the ISA, so many that we
cannot execute the musl libc, is proof of that.

This patch set should probably be reviewed and merged, or we should
drop the whole target.
