Comment(by igloo):
OK, looks like this is deliberate:
{{{
forceRecompile :: DynP ()
-- Whenver we -ddump, force recompilation (by switching off the
-- recompilation checker), else you don't see the dump! However,
-- don't switch it off in --make mode, else *everything* gets
-- recompiled which probably isn't what you want
forceRecompile = do dfs <- liftEwM getCmdLineState
when (force_recomp dfs) (setGeneralFlag
Opt_ForceRecomp)
where
force_recomp dfs = isOneShot (ghcMode dfs)
}}}
I think it would be best to just adjust the docs to match.
