   I am never quite sure how I’m supposed to read those two coverage reports. :sweat_smile:

   If I read it right, the main branch has no coverage of sha256_avx2.cpp, sha256_sse4.cpp, and sha256_sse41.cpp, while the feature branch has full coverage of those three, but the main branch had full coverage of sha256_x86_shani.cpp and the feature branch has none. Are these different architectures where only one or the other applies?

   

   Otherwise looks like some nice NgU

   Yeah, it is a bit unfortunate that they were produced on machines with different hardware. I guess I can try to normalize them in configure somehow.

   Draft for now to look into the timeout.
8. Temporarily remove fuzz input which times out
