Marc Tiehuis 7a3fd89d25 Add Sha3 hashing functions 
These are on the slower side and could be improved. No performance optimizations
yet have been done.

Interestingly, release-safe is producing slightly better code than
release-fast.

we still want to support it, but there are too many bugs

Andrew Kelley fa024f8092 error return trace pointer prefixes other params 
instead of being last. This increases the chances that it can
remain in the same register between calls.

Merge pull request #686 from zig-lang/md5-sha1 
Add Md5 and Sha1 functions
 2018-01-13 00:00:33 -05:00
Marc Tiehuis 51fdbf7f8c Add Md5 and Sha1 hash functions 
Some performance comparisons to C.

We take the fastest time measurement taken across multiple runs.

The block hashing functions use the same md5/sha1 methods.

In short, zig provides pretty useful tools for writing this sort of
code. We are in the lead against clang (which uses the same LLVM
backend) with us being slower only against md5 with GCC.
