The other changes need a proper ifdef, but should be ok I > guess. -mimplicit-it=always will have no effect on ARM builds as it defaults to 'arm', meaning that IT instructions are already optional in ARM mode, and switching to 'always' changes the behavior only for Thumb mode. For -mauto-it, it is not documented in the gas documentation online or in my current as' --target-help. I'll dig this deeper today, but barring any scream from me, the change above is fine globally in U-Boot. > -- > Stefan Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
