math-68881.h vs -ffast-math

Wed Feb 9 23:40:00 GMT 2011

Hello.

The file gcc/config/m68k/math-68881.h is distributed with GCC. It is about 
inlining the libm functions using FPU instructions on m68k targets.

But -ffast-math seems to serve the same purpose, even better.

My question: Is math-68881.h still useful for some purpose ?

BTW: That file does not support C99, I have just posted a patch to fix that.
