SSTATUS/MSTATUS issues with FS bit #31

Closed dkohlbre closed 5 years ago

dkohlbre commented 5 years ago

At the least, we are clearing the FS bit when we enter the enclave. This fully disables the FPU.

Its possible that there are further issues with status bits as well.

We'll want to revert PR #30 once we figure this all out.
