The most surprising thing to me is that they can parameterize a nontrivial section of the implementation space of a function, or that such a section exists that hasn't been optimized away by the compiler.
- nicovasilache 9y agoThe thing is that compilers usually quickly go to SSA form and it is not the best IR to optimize loops in. Then you fight it to extract a high-level IR and this little process makes it very easy to lose high-level information. We don't do this so we begin from a friendlier starting point.
