Hi! Does anyone know how well Think C 4.0 optimizes 68881/2 instructions for concurrency? If the compiler does a pretty good job then I won't need to waste my time hand coding fpu instructions in assembly. rick@wam.umd.edu

In fact, no Mac-based compiler that I know of optimizes the 68882 instructions for concurrency. (The 68882 is the only one of the two chips that supports instruction concurrency.)
