Hi, 
We should try to understand why CFI thinks the prototypes of the two
symbols are different. There are still a number of issues with CFI, so
papering over them by reverting stuff that we want for good reasons is
not the way to go imo.

In the short term, you can work around it by avoiding the indirect
call to blake2s_compress, e.g.,
Thanks for the patch. I tried it and the issue remains.
As Jason said, he cannot reproduce this issue. I will try another version
of clang next.
