#8842: Make sure msys2 builds non emulating binaries ------------------------------------+--------------------------------- Reporter: schyler | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.1-rc2 Keywords: | Operating System: Windows Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+--------------------------------- I came across this in my own project. MSys2 doesn't enter #ifdef blocks which test for _WIN32. Instead, it pretends to be Linux and has a set of headers which emulate things like mmap. These emulation functions are really really slow -- in my personal tests about 10x slower than calling the WINAPI -- so this ticket is just a reminder (it may already be done) for someone to check that MSys2 builds things non-emulated in GHC. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8842 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
