Thanks for the review.

I had made the changes you requested and am working on reducing the
number of failing RV32 tests cases but I noticed you commit patch 1
and 2. Thanks for doing that.

It'll take me some time to reduce the failing RV32 test cases, when I
have a better idea on everything I will send a v2.
