I tried compiling with -msoft-float option and I start getting linker
errors for functions like __muldf3, __adddf3, etc...
The MAN page states that GCC does not provide these functions. (even
though I am building for 386).
So my question is this:
Do embedded users who do not have a floating point unit on their
processors write their own math emulation library? This seems to me to be
too much of a problem. I am not used to worrying about being able to
multiply and divide. I would rather buy a package (at least for standard
processors like 386, PowerPC,...).
Are there any commercial or freeware packages out there which I can use?
Thanks
