Tobias, et al., Attached is the my autovectorization pass. I've fixed a bug that appears when using -bb-vectorize-aligned-only, fixed some 80-col violations, etc., and at least on x86_64, all test cases pass except for a few; and all of these failures look like instruction-selection bugs. For example: MultiSource/Applications/ClamAV - fails to compile shared_sha256.c with an error: error in

Tobias, I've attached the latest version of my autovectorization patch. I was able to add support for using the ScalarEvolution analysis for load/store pairing (thanks for your help!). This led to a modest performance increase and a modest compile-time increase. This version also has a cutoff as you suggested (although the default value is set high (4000 instructions between pairs) because

This is entirely up to you, as you're basically implementing the semispace

We have a few questions about the current state of GC. We decided to start (and finish?) our work by finishing SemiSpace. process_pointer is meant to move objects from CurSpace to OtherSpace. How can it find pointers to a moved object? How does it know the size of each object? Assuming we are writing a GC that will only work from llvm assembly our best option seems to be forcing the assembly code
