If they're not, GHC tries to execute an unnamed executable, resulting in error messages such as: Error (figuring out LLVM version): : runInteractiveProcess: invalid argument (Invalid argument) <no location info>: Warning: Couldn't figure out LLVM version! Make sure you have installed LLVM This regression was introduced in e6bfc596. Test Plan: Build GHC and test if --info shows sensible values of "LLVM llc command" and "LLVM opt command" Reviewers: austin, #ghc Reviewed By: austin, #ghc Subscribers: austin Projects: #ghc Differential Revision: https://phabricator.haskell.org/D190 GHC Trac Issues: #7143 }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7143#comment:22> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
