Are there any other uses for module-level attributes anticipated? Do you anticipate defining what ImageInfo, CorrectedSynthesize, GCOnly, etc. mean in LangRef.html, or are they just going to be left as "The is for ObjC." ?

...A, __objc_imageinfo, regular, no_dead_strip" With module-level attributes, these global variables wouldn't exist. Instead, they would be replaced by something like this: -fno-objc-gc: module attr ImageInfo [CorrectedSynthesize] -fobjc-gc-only: module attr ImageInfo [CorrectedSynthesize, GCOnly] LTO would see that the module attributes are incompatible and will reject trying to link the two modules.
