Hi,
So this is my second attempt at finding a way to improve how we generate
the vector IV's and teach the vectorizer to share them between main loop
and epilogues. On IRC we discussed my idea to use the loop's control_iv,
but that was a terrible idea and I quickly threw it in the bin. The mai

Hi Richi,
So I'm trying to look at what IVOPTs does right now and how it might be
able to help us. Looking at these two code examples:
#include
#if 0
int foo(short * a, short * b, unsigned int n)
{
int sum = 0;
for (unsigned int i = 0; i < n; ++i)
sum += a[i] + b[i];

Hi,
The aim of this RFC is to explore a way of cleaning up the codegen
around data_references. To be specific, I'd like to reuse the
main-loop's updated data_reference as the base_address for the
epilogue's corresponding data_reference, rather than use the niters. We
have found this leads t
