#11445: Turn on SplitSections by default -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: task | Status: new Priority: normal | Milestone: 8.2.1 Component: Build System | Version: 8.0.1-rc1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: 11285 Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by refold): The gold linker only supports ELF, so it can't be used on OS X and Windows. GNU ld didn't support `--gc-sections` for PE/COFF [https://sourceware.org/git/gitweb.cgi?p=binutils- gdb.git;h=0f088b2a9417b1d4ed597849ffa671eba25f5051 until recently], and this feature [https://ghc.haskell.org/trac/ghc/ticket/8405#comment:20 still appears to be buggy] according to olsner. So we'll need to fix those bugs in ld to make `-split-sections` work on Windows. According to the links you provided, OS X ld doesn't support `--gc- sections` at all, but maybe the `-dead_strip` option could be used. So on ELF platforms `-split-sections` should be ready to replace `-split- objs`; further testing and investigation is necessary on Windows and OS X. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11445#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
