[AMD Official Use Only] Maxim,
This is really difficult for me to work on this as I do not have various targets and HW affected. I am sure there were quite a lot of progressions, but as I said in the beginning regressions are also inevitable, just like every time a heuristic is involved. For the hmmer case I was getting quite different results just by selecting a different ARM target. So without a good way to measure it and given the heuristic approach I cannot satisfy all the requests from multiple parties. Our target (AMDGPU) does this for a long time and I believe it is overall beneficial. It is somewhat pity I cannot make this a universal optimization, but I am also time constrained as there is other work to do too.

Two observations from this: 1. 456.hmmer is very sensitive to this optimisation 2. LTO screws up on 456.hmmer. -- Maxim Kuvyrkov https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.linaro.org%2F&data=04%7C01%7CStanislav.Mekhanoshin%40amd.com%7C06739cf07d704b0ae9c808d9833ab4db%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637685110452392032%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=lT0JQgOBKwpI7H04MR%2BBFww5RKAiXTq3XQiLEBQSBCE%3D&reserved=0 > On 29 Sep 2021, at 14:06, Maxim Kuvyrkov <maxim.kuvyr...@linaro.org> wrote: > > Hi Stanislav, > > Just FYI.
