#9952: Add -g<level> -------------------------------------+------------------------------------- Reporter: tibbe | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.4 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- We should add debug info levels, just like GCC and LLVM has. In particular, I'd like to have -g1 which has (from https://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html) program that you don't plan to debug. This includes descriptions of functions and external variables, and line number tables, but no information about local variables. This should let us have -g1 turned on even in production code, as it should grow binary sizes by much. This in turn should be a boon for debugability of programs. It should also allow us to offer some for of stack traces without any runtime cost (except when an exception with a stack trace is actually raised.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9952 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
