What is the meaning of "-f68881" to the Sun3 C compiler? I empirically observe that it generates inline add/sub/mul/div floating-point instuctions, but still generates calls to external math library/ies for the math/trig functions (_fmod, _sin, etc.). What is it supposed to do? Is there actually a specification somewhere in Sun's manual set -- I looked in the Floating Point User's Guide, didn't find much help beyond a some- what content-free In-line code generation puts floating-point instructions in line with CPU instructions; such code generated in-line for specific hardware, ..., only runs on machines with the specific hardware... Why doesn't -f68881 take advantage of the hardware sin/etc. functions? You can email me (rdh @ sli.com -or- uunet!sli!rdh) directly, I'll cull/summarize the replies. Thankx in Advance!
