Thus the lookup fails since the domain of the GlobalRdrEnv is affected by the RdrName's OccName's FastString's unique. -The old `reinitializeGlobals` mechanism is enough to provide the plugin with -read-access to the table, but it insufficient in the general case where the -plugin may allocate FastStrings. This mutates the supply for the FastStrings' -unique, and that needs to be propagated back to the compiler's instance of the -global variable. Such propagation is beyond the `reinitializeGlobals` -mechanism. - Maintaining synchronization of the two instances of this global is rather difficult because of the uses of `unsafePerformIO` in this module. Not synchronizing them risks breaking the rather major invariant that two |
