...gister Given what we know of Larrabee and speculating that the "Knights" family is likely a derivative of it, it's safe to assume that future Intel architectures will be much more like traditional vector machines. That means gather/scatter, element indexing, etc. The existing PINSR/PEXTR and shuffle instructions already allow a degree of element indexing. Note that the existing LLVM vector types already have insert/extract operators. Unifying array and vector and generalizing the result would open a lot of optimization opportunities. -Dave

Andrew, your response highlights a naming problem in LLVM, which is that "array" and "vector" mean the same thing in normal computer language and compiler theory usage, so it is inconvenient and misleading within LLVM to give one a very specific meaning that is different from the other.... to the LLVM developers I would suggest using the term
