#13392: ghc --show-options lists flags twice ---------------------------------+-------------------------------------- Reporter: ThreeFx | Owner: (none) Type: bug | Status: new Priority: low | Milestone: ⊥ Component: Compiler | Version: 8.0.1 Resolution: | Keywords: newcomer Operating System: Linux | Architecture: x86_64 (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ---------------------------------+-------------------------------------- Comment (by SantiM): Hello, I'd be happy to take this issue as my first contribution to GHC. I wanted to ask a few questions first though: 1) I didn't find tests on the 'ghc' command or the "showOptions" function[0]. Any suggestions on where to put the test for this change and how to go about it? 2) We could fix this by just adding 'nub' to the showOptions, but I guess that is not good enough and we probably want to take a look at how flags are registered in DynFlags. Ideas?
