...block has N candidate pairs, then they could all be
connected, but then there are only N of them. In this extreme, the
algorithm is also O(N^2). Because both extremes are O(N^2), I've
generally figured that this is also O(N^2), but I may want to do more
math for the paper I'm writing.
fuseChosenPairs - This is linear in the number of selected pairs, and
that number scales with the number of instructions in the BB. In the
worst case, after each fusion, a number of instructions need to be moved
(up to almost the total number in the block). Thus, this is also O(N^2).

This happens at several places. Can you check your code for this.

'repl' is no obvious abbreviation for me. Can you use the full word or
equivalent shorter one?

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:

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
