data SourceModified Source #

Indicates whether a given module's source has been modified since it was last compiled.

Constructors

SourceModified

the source has been modified

SourceUnmodified

the source has not been modified. Compilation may or may not be necessary, depending on whether any dependencies have changed since we last compiled.

SourceUnmodifiedAndStable

the source has not been modified, and furthermore all of its (transitive) dependencies are up to date; it definitely does not need to be recompiled. This is important for two reasons: (a) we can omit the version check in checkOldIface, and (b) if the module used TH splices we don't need to force recompilation.
