Transcendental and Auxiliary Functions
PowerPC assembly language does not directly support any of the IEEE auxiliary functions or the transcendental functions listed in this book. If you are writing a numerics application in assembly language, you can access the routines in the C library MathLib to perform these operations, provided you set up the stack frame properly. For information on how to set up the stack frame, see the book Assembler for Macintosh With PowerPC.
