Incidentally, I did boot up the simulator again the other day because
I had had an idea for how we might get the regression tests to pass.
However the idea didn't pan out. I thought maybe we could compile just
float.c with -msoft-float so that the backend used VAX floats and the
user datatype was represented by IEEE floats. I'm sure there are a few
places where we assume we can convert one to the other but I was
hoping it would be few enough to be manageable to fix up. I wasn't
sure how feasible it was to have a mixed build at all and I was going
to experiment.
However gcc doesn't support -msoft-float on VAX. Apparently
-msoft-float is an implemented by the architecture backend rather than
as a portable general purpose feature :(
