True if the @code{.debug_pubtypes} and @code{.debug_pubnames} sections should be emitted. These sections are not used on most platforms, and in particular GDB does not use them.

True if sched2 is not to be run at its normal place.
This usually means it will be run as part of machine-specific reorg.
