Hi Richard, > Do we document target specific deviations from "default" behavior somewhere?
Not as far as I know. The other option changes in arm-common.c are not mentioned anywhere, neither is any of arm_option_override_internal. If we want to keep documentation useful, we shouldn't clutter the generic options with target-specific deviations from the default settings. What might be feasible is adding a section for each target which describes changes from the default settings. Wilco
