Can anyone tell me how to mix code so that it will be able to take best
advantage of the math system available. That is, if an FPU (881/2) is
available to use it; otherwise use SANE; or if the user wants to use
SANE via the math chip? I know it is possible (there are benchmarks that
let the user decide how to do math), but I can not figure out how to do
it. I would be working in either Pascal or C (rather avoid Assembly) in
the MPW environment. I have tried just having parts of code compiled for
881 direct and other compiled normally, but you can not seem to mix
them. THe linker did not like it. Worse, FPU code requires 68020 code
and it does not seem possible to mix 68020 and 68000 code together. I am
obviously missing something and it is probably simple. HELP! Thanks in
advance...
 
BTW, figuring out what is available is no problem.
