#8405: experiment with using function-sections for linking (for smaller libs and executables) -------------------------------------+------------------------------------- Reporter: carter | Owner: olsner Type: task | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by olsner): * owner: => olsner Comment: It seems GNU ld actually has scalability issues with very large numbers of sections too, unfortunately. Found out because I was building libHSghc with split sections, and getting 10 minute link times on some test cases with plugins linking statically against ghc... Since split-objs is specifically disabled for that code I simply disabled split-sections as well. A much cleaned up version of the patch now at https://github.com/olsner/ghc/commits/function-sections-2 - this adds a -split-sections flag that controls the splitting when compiling Haskell code. --gc-sections is always added to the linker command line. (Vague rationale being that after building libraries with split sections, we'll want to bring space savings to users without manual steps or extra flags building their programs/libraries.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8405#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
