updates for the monero-v1 pow tweaks #88

Open vtnerd opened 6 years ago

vtnerd commented 6 years ago

These are updates for the monero - version 1 PoW changes. For this version, I modified the long state directly instead of manipulating some of the state variables. The entire context is heap allocated, so I wasn't sure what the compiler was going to do with aliasing already. Some other versions I modified the state directly, especially if they were stack variables.

Also note that this is going directly into the master branch, and not the dev branch.

Any chances of this getting merged?
