#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 olsner):

So on ELF platforms -split-sections should be ready to replace -split- objs; further testing and investigation is necessary on Windows and OS X.

OS X should just use the built-in subsection support. For non-Linux ELF platforms, an issue is that `--gc-sections` (under that name) is only available from GNU ld, other linkers might not have it or might call it something else. That means dropping `-split-objs` probably would leave some platforms without dead-code stripping at all. It should be good to go with GNU ld on non-Windows though. And for unixes without GNU ld we could get configure to check if the linker has something like `--gc-sections` and how to activate it. (Looks like e.g. Solaris has a `-z discard-unused=sections` flag.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11445#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
