 It was actually Richard's mips.exp rewrite that removed { target { fixed_point
 } }  from these tests.

 Richard, was this intentional?  It seems to me that since fixed-point is not
 dependent on a command-line flag (-mdsp is orthogonal) the effective-target
 check is correct here.

 Should I revert it like this:

Yeah.  Sorry, I hadn't realised you could actually disable _cc1_ support
for fixed point.  (I knew you could disable libgcc support, but that's
not a problem for these compile-only tests.)

The fixed-point tests fail to compile when configure with
--disable-fixed-point.

I think the easiest would be to extend Richard's new infrastructure with a new
keyword and then skip these tests completely.  I take a look if this sounds
good.

This is at most a documentation problem.
