Oh, i forgot to see if anyone did this before #4933

Hello, thanks for the PR! This looks simpler than #4933.

which uses a different polynomial that is used internally by the Dear ImGui currently).

I would want to tackle this first.
What would it take to change the regular C++ implementation to have output matching the use of _mm_crc32_u8() ? (and potentially of wider versions _mm_crc32_u32 if we decide it is worth using them).

That would require to change only current crc lookup table

Changed it, now it produces same results with or without native instruction.

This is merged (in reverse order) as e6dd8f6 + 326dc95
I also updated test engine to match. Thank you!
