it's an automatically generated getter/setter, but a procoption. This way we no longer have to save/restore the synthetickind procdef field to/from ppu's. This way we can modify the field also after the interface has been parsed without affecting the crc (e.g. when creating wrappers for high level targets for routines that are only declared as "external" in the implementation) git-svn-id: trunk@34129 -
