A large part of that would be better support for integer math, and 64 bit in particular for sha1

Why are 64-bit integers useful for SHA-1 which uses 32-bit words?

The full product of 32-bit multiply is 64-bit.

I don't think SHA-1 uses any multiplications, only bitwise operations (not, and, or, xor), addition and rotation.
