We hit this bug on OS X (precisely the same thing as here: http://stackoverflow.com/questions/24796874/cant- install-diagrams-arithmoi-on-mac — arithmoi now uses LLVM backened by default). My company's software can't be installed on Windows nor OS X because of this one and it's… well, ''quite problematic'', as our customers require the Windows version (and most probably OS X too). The workaround – disabling LLVM – is not possible since we use it (vide ''accelerate''). In other words: solving this is crucial for our company. Is it possible to fix it by 7.8.4? -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7143#comment:16> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

[GHC] #9294: More exports and documentation for GHC API Parser Module

#9294: More exports and documentation for GHC API Parser Module ------------------------------------+------------------------------------- Reporter: agibiansky | Owner: agibiansky Type: feature request | Status: new Priority: normal | Milestone: Component: GHC API | Version: 7.8.2 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- I would like to be able to use the GHC API for parsing. Right now this is in the Parser and Lexer modules: Parser: http://www.haskell.org/ghc/docs/7.8.2/html/libraries/ghc-7.8.2/Parser.html Lexer: http://www.haskell.org/ghc/docs/7.8.2/html/libraries/ghc-7.8.2/Lexer.html GHC currently exposes only a few parsers here. I'd like to make a few modifications: 1. Expose a few more parsers than currently are exposed in the Parser module. In particular, I'd like import statements, type signatures, declarations, and expressions, at least, in addition to what's already there. 2. Add some Haddock documentation to the top of the Parser module describing how to use it, since the types themselves are pretty opaque here. 3. Export a clean and self-contained parsing API from the GHC module.
