#16007: Implement `-Os` -------------------------------------+------------------------------------- Reporter: sgraf | Owner: (none) Type: task | Status: new Priority: normal | Milestone: ⊥ Component: Compiler | Version: 8.6.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: #16005 Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Popular C compilers like GCC or clang allow to optimise for binary size. Since there are multiple ways in which GHC trades code size for faster programs, it might make sense to follow suit. This ticket is for tracking which optimisations/hacks in the compiler might be affected, as well as Feel free to add items to the following list: - +0.1% increase in code size due to known calls instead of re-using generic apply thunks in #16005 - -0.1% due to `-fstg-lift-lams` #9476 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16007 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
