#13237: Extend TH with addModCStub -------------------------------------+------------------------------------- Reporter: | Owner: facundo.dominguez | facundo.dominguez Type: feature request | Status: patch Priority: normal | Milestone: 8.2.1 Component: Template Haskell | Version: 8.0.1 Resolution: | Keywords: inline-c Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3106 Wiki Page: | -------------------------------------+------------------------------------- Comment (by nh2): One question about the implementation: Do we have to be careful with recompilation avoidance / reproducible builds / interface hashes here? E.g. if the `String` passed to `addModCStub` is different between two builds, should that invalidate any modules further down? Or could, through recursive tracing of `include`s, the behaviour of a module change when the module is loaded from TemplateHaskell, so that e.g. the entire preprocessor-expanded C code should make its way into an interface hash? (Note I haven't actually analysed if it's possible for the generated C code to be used in TemplateHaskell later in the same compilation pass, just some ideas that went through my head.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13237#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
