Unfortunately, the ABI selection it makes can be unsafe if it changes how a result is returned because not enough information is available via the RETURN_IN_MEMORY hook to determine where the function gets used. This can result in some parts of the compiler thinking a value is returned in memory while others think it is returned in registers. To mitigate this, this patch temporarily disables the optimization and falls back to using the default ABI for the translation. gcc/ChangeLog: PR target/96882 * config/arm/arm.cc (arm_get_pcs_model): Disable selection of ARM_PCS_AAPCS_LOCAL.
