Well, VAX doubles are a bit out of scope for an IEEE emulation
library :-)

It does sound like that's the best place for it. In that case, you
don't want to add a flag to the softfloat float_flags -- they are
specifically for indicating softfloat's status/exceptions. Flags
handled purely in CPU-specific code should be stored in the
CPU specific state struct somewhere.
