The access type is classified as a store/AMO in the event of an
access-fault, page-fault, or guest-page
fault exception triggered by shadow stack instructions.

Don't send reset from HTIF, if no binary is given
This applies when the binary is set to "none".
This is useful when implementing a binary loading
mechanism outside of the HTIF, and the bootloader
is supposed to boot from that.

cosim: fix right shift on neg number and remove redundant mask
referece from: ISO C99 (6.5.7/4)
"The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated
bits are filled with zeros. If E1 has an unsigned type, the value of the
result is E1 × 2E2, reduced modulo one more than the maximum value
representable in the result type. If E1 has a signed type and
nonnegative value, and E1 × 2E2 is representable in the result type,
then that is the resulting value; otherwise, the behavior is undefined."
list the affectections. X means it is problematic and fixed by change
operand type / redundant mask
