FSE performance optimizations

Hello, I am working on the FSE performance optimizations and trying to implement 8-states instead of the default 2-states, which might accelerate the decompressing by processing the 8-states in parallel. To process the 8-states, I changed the bitContainer to a __m128i type and modified all the related functions. Some files were compressed and decompressed correctly for the tests, but some were corrupted because of minor differences between the decoded and the original files.
I tried to find the bug but couldn't make it. I would like to know if it is possible to have someone check my code or discuss it with me? Thank you!
