Which effectively translates into a second test of the Intel PSW,
since it appears from Haitao's comments they are unit testing against
the new driver.

Unless of course you wired up the OpenEnclave infrastructure to use
the new VDSO and exception handling, as that would be a significant
test, is that the case?

Getting a real live enclave loaded and initialized in memory is
essentially a contract with the enclave ELF parser and metadata
interpreter that the runtime implements.  There is nothing subtle
about whether or not that is working correctly.  The acid test after
that is the enclave entry and exit handling which is ultimately a
function of the exception handling.

Have a good remainder of the week.
