[GHC] #16107: Update GCC compiler & friends
#16107: Update GCC compiler & friends ----------------------------------------+--------------------------------- Reporter: flip101 | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.3 Keywords: | Operating System: Windows Architecture: Unknown/Multiple | Type of failure: None/Unknown Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ----------------------------------------+--------------------------------- gcc used by ghc is now about 1.5 years old. It's going to take some time for a new GHC release as well. Would be good to update gcc too. Probably it's backwards compatible with old gcc so would be easy to patch. https://github.com/ghc/ghc/blob/f11f2521aff16edca150e6eed5102a3da7e4f59a/mk /get-win32-tarballs.sh#L104-L114 source code also points to other tools of which some have newer versions.

I'm not sure whether there is anything keeping us on the `gcc` release we use currently. Tamar, should I just go ahead and try updating it? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16107#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Originally no GCC 8 builds were available, I fixed this with upstream and the 64-bits were released but the 32-bit ones are still failing https://gcc.gnu.org/ml/gcc/2019-01/msg00178.html which is what I'm working on with upstream now. The problem is I don't particularly want a different toolchain and runtime for the 32-bit and 64-bit toolchains as it'll be confusing for the users but also we don't test the 32-bit ones often, so we'll likely to break it with a different toolchain. If we want to update before the tarballs are released by mingw-w64 we'll have to spin our own binaries disabling the ada bootstrap. the CRT I haven't updated due to a weird behavior with NaN and INF in a testcase, though that may have been fixed now. Haven't checked yet. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16107#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

That said unless you're having a specific issue with the toolchain I doubt you'll see a difference. GCC backports are quite conservative. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16107#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
