A lot has happened in the meantime. Some things I’ve been working on: An llvm code generation backend Optimizing broadcasting (Fortran’s SPREAD) through loopinvariant code motion where possible Finding optimal tiling parameters Optimal strength reduction for index calculation Ways to … Continue reading
I keep forgetting to blog, so here goes. The vector expression compiler has gained a good number of specializations, such as – strided (with a preference to C or Fortran order) – inner dimension contiguous (C/Fortran) – contiguous (C/Fotran) – … Continue reading
I’m going to take a break for a week or so, to give my shoulders some rest, since they’ve been troubling me.
I started a new project to compile vector expressions using any code generation backend. The project allows easy mapping of foreign ASTs and types onto the new project’s AST and type system, and then specializes the AST according to the … Continue reading
The refactoring has begun, buffer and memoryview indexing is now separated (http://tinyurl.com/cb86mn4), but at some point we need to rewrite all type analysis as a (set of) transforms. I’m going to split the type analysis some more, and refactor some … Continue reading
