GHC.Iface.Recomp.Flags

Description

This module manages storing the various GHC option flags in a modules interface file as part of the recompilation checking infrastructure.

Synopsis

fingerprintDynFlags :: HscEnv -> Module -> (WriteBinHandle -> Name -> IO ()) -> IO Fingerprint
fingerprintOptFlags :: DynFlags -> (WriteBinHandle -> Name -> IO ()) -> IO Fingerprint
fingerprintHpcFlags :: DynFlags -> (WriteBinHandle -> Name -> IO ()) -> IO Fingerprint

Documentation

fingerprintDynFlags :: HscEnv -> Module -> (WriteBinHandle -> Name -> IO ()) -> IO Fingerprint Source #

Produce a fingerprint of a DynFlags value. We only base the finger print on important fields in DynFlags so that the recompilation checker can use this fingerprint.

NB: The Module parameter is the Module recorded by the *interface* file, not the actual Module according to our DynFlags.

fingerprintOptFlags :: DynFlags -> (WriteBinHandle -> Name -> IO ()) -> IO Fingerprint Source #

fingerprintHpcFlags :: DynFlags -> (WriteBinHandle -> Name -> IO ()) -> IO Fingerprint Source #
