In arm-eabi cortex-m55 hard, after: | commit gcc-17-761-g44c5f9a37aa | Author: Andrew Pinski <[email protected]> | Date: Mon May 25 12:44:48 2026 -0700 | | match: Fix up `(smaller)a ==/!= (smaller) b` pattern for pointers [PR125453] | | While reviewing r17-632-g1c9808a71207eb, I missed that it was valid (in gimple) | to cast from a pointer to a smaller integral type. That meant with that | pattern we would get `ptr ^ ptr` which is invalid gimple. | ... 16 lines of the commit log omitted.
