Hi Paul,

Why do you need this facility ?  Currently the specs strings
constructed for gcc translate a -mhard-float or -msoft-float switch
into the correct hard or soft floating point switches for gas so there
is no need to support them directly.

There is however a good reason not to support them - they are too
simplistic.  When -msoft-float is specified for example - there is no
indication what kins of software floating support should be enabled.
None at all ?  soft-VFP ?  soft-FPA ?

Cheers
