--- Comment #11 from Andrew Macleod <amacleod at redhat dot com> --- To be clear, the reason it is unlikely to be ported to GCC12 is because this depends on relation support in GORI to recognize the LHS and operand 1 are equivalent. That support was first added in GCC13, and is too significant a chunk of work to port back to GCC12.
