We have ported DJGPP to operate as a cross-compiler/environment
for PC-hosted development of code for SPARC processors. Our environment
is SPARC embedded system boards with parallel/serial IO, timers etc.
for teaching embedded systems techniques to undergrads, and for
developing embedded systems for internal/external projects.

Our target boards have just the SPARC integer units on them, being
simple embedded targets, but we would like to have the 'occasional'
facility to use floating point via libraries.

Compiling programs with GNU using '-mno-fpu' produces all the
usual correct function calls to library routines that should
emulate floating point. What we would like though are some
portable C source code routines for implementing the floating
point operations to IEEE specifications preferably.

We could sit down and write them, but before reinventing the wheel,
I just thought we ought to ask if anyone out there has come
across a PD set of C or C++ sources that already do this?

Many thanks for looking!
