--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> 2011-03-24 14:01:18 UTC --- Does the target in question define TARGET_PROMOTE_PROTOTYPES to return true? If so, the front end is behaving as requested by the target - while it would be better for this to be implemented as a lowering phase some time after the front end is finished, to the extent that the hook represents meaningful ABI or optimization information, that's not the internal interface at present.
