[LLVMdev] [llvm-commits] [PATCH] BasicBlock Autovectorization Pass
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
