    arm: Zero/Sign extends for CMSE security on Armv8-M.baseline [PR115253]

    Properly handle zero and sign extension for Armv8-M.baseline as
    Cortex-M23 can have the security extension active.
    Currently, there is an internal compiler error on Cortex-M23 for the
    epilog processing of sign extension.

    This patch addresses the following CVE-2024-0151 for Armv8-M.baseline.

    gcc/ChangeLog:
