[LLVMdev] ARM vectorizer cost model
...TTI
Yes, this direct access is very convenient. For now, I'll focus on A9 and
later we can add the subtleties of each sub-target.
cheers,

Hi Renato,

Yes, I am starting to work on the ARM cost model and I would appreciate any help in the form of: advice, performance measurements, patches, etc.
I tune the cost model by running the cost model analysis pass and I compare the output of the analysis to the output

[LLVMdev] ARM vectorizer cost model
Hi Nadav,
I'm interested in knowing how you'll work up the ARM cost model and how
easy it'd be to split the work.
As far as I can see, LoopVectorizationCostModel is the class that does all
the work, with assistance from the target transform info.
Do you think that updating ARMTTI would be the best course of action now,
and inspect the differences in the CostModel later?
