Detailed Description

ISA constraints specify the kind of instruction constraints a task variant requires for its execution. At a high-level this will be controlling which kind of low-level runtime processor we can map this onto. Note that some constraints such as Terra and LLVM do not correspond to actual low-level processor kinds, but represent variants which can be JIT-ed to different target processors on demand. The LLVM and Terra kinds can also be mixed with other constraints to say specifically which target processors the task can be JIT-ed to.
