   This is a trivial test program which may be useful to people who are
   porting the GCC or G++ compilers to a new system.  The intent here is
   merely to check that all floating-point operations have been provided
   by the port. (Note that I say ``provided'' rather than ``implemented''.)

   To use this file, simply compile it (with GCC or G++) and then try to
   link it in the normal way (also using GCC or G++ respectively).  If
   all of the floating -point operations (including conversions) have
   been provided, then this file will link without incident.  If however
   one or more of the primitive floating-point operations have not been
   properly provided, you will get link-time errors indicating which
   floating-point operations are unavailable.

   This file will typically be used when porting the GNU compilers to
   some system which lacks floating-point hardware, and for which
   software emulation routines (for FP ops) are needed in order to
   complete the port.
