#16084: Improve link times on Windows -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: upstream Priority: high | Milestone: Component: Compiler | Version: 8.6.3 Resolution: | Keywords: Operating System: Windows | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari):
LLD won't magically help here. Latest improvements by Martin Storsjö (mstorsjo) have made LLD able to link some mingw gcc-generated code, but, alas, when assembling GHC-generated assembly, mingw gas produces (I believe this is a sort of "optimisation") non-standard relocations.
Frankly I wonder how difficult it would be to add support for these relocations. Given that LLVM code is generally pretty approachable I suspect that would be the easiest path forward. In the meantime I have been pursuing testing Tamar's binutils patch. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16084#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
