Re: [PATCH 5/5] [AARCH64] Add variant support to -m="native"and add thunderxt88p1.

What is currently submitted for LLVM review was submitted before we determined this naming scheme. I will mark the current submittal as abandoned, as the scheduling model needs to be split out and revised. Joel Jones Sent from my AArch64 powered iPhone > On Nov 2, 2016, at 3:55 AM, James

[PATCH] Fix store-merging alias check, apply some TLC

This fixes the alias check in terminate_all_aliasing_chains -- the base we use for the hash table indexing does not constitute an object that aliases all stores in the chain (consider for example the MEM_REF handling which strips the offset completely). I've refactored data structures a bit in
