Regarding the suggestion of being able to get SIN and COS or (DIV and REM) at
the same time - all you need is a good compiler!
I believe that the VAX/VMS FORTRAN compiler looks for computations of SIN(X)
and COS(X) and calls a special entrypoint into the run-time-library which returns
BOTH values at once. Similarly, I designed (but never implemented) a modification
to the BLISS compiler which would have done the same thing for DIV and REM - I don't
know if this was actually finished after I left DEC.
By the way, I'm unaware of the existance of any "good" C compilers. [ A "good C
compiler" is definitely an oxymoron!]
