I get your point. However, I don't think it is useful to consider a compiler to be a replacement for programmers. Compilers are tools for programmers. The more time a compiler saves a programmer, the better it is. I think there is a middle ground between writing inline assembly and fully automatic vectorization that would be less time intensive than manual vectorization and more predictable and available earlier than fully automatic vectorization. I wonder what would have to be done to find it and provide support for it in GCC/LLVM.
