#9358: Improve flag description in the user guide -------------------------------------+------------------------------------- Reporter: jstolarek | Owner: Type: bug | Status: new Priority: low | Milestone: 7.10.1 Component: Documentation | Version: 7.8.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Easy (less than 1 | Type of failure: hour) | Documentation bug Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Sections 4.20 (Flag reference) and 4.10.2 (-f*: platform-independent flags) of the User Guide could use some updating: - `-floopification` is mentioned in 4.20 but not in 4.10.2 (which, sadly, is my fault), - Section 4.10.2 says: "These flags turn on and off individual optimisations. They are normally set via the -O options (...) The flags below are off by default, except where noted below." Does the last sentence mean they are on by default for `-O` or that they are enabled even with `-O0` (which is the default optimisation level)? - What is the default value of `-fmax-simplifier-iterations`? - 4.20 mentions `-fmax-simplifier-iterations`, `-fmax-relevant-bindings` and `-fmax-worker-args` but only the first one is described in 4.10.2 I suspect there are more inconsistencies. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9358 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
