RTEMS (Real-Time Executive for Multiprocessor Systems) is a free open source real-time operating sys

--  fp.inc

--  Macros to produce a large number of LOCAL floating point variables.  This
--  preprocessing is necessary to insure that the variables are
--  scoped properly and to avoid duplicating hundreds of lines
--  of code.

-- DEFICIENCIES:  
--
-- 1.  This currently does not address whether or not the CPU
--     actually has hardware floating point.  It just does the work.
