Register NaT consumption faults exception
Fatal exception 0xC00002C9
A NaT value is consumed on a non-speculative instruction. A non-speculative operation, such as a load,
store, control register access, instruction fetch, read
a NaT source register, NaTVal source register, or referenced a NaTPage.
In the I64 here are 128, 64-bit general-purpose registers that
are used to hold values for integer and multimedia computations. Each
of the 128 registers has one additional NaT (Not a Thing) bit that is
used to indicate whether the value stored in the register is valid.
Execution of I64 speculative instructions can result in a register's
NaT bit being set.
