[PATCH] D70467: [Distro] Bypass distro detection on Windows

[Reid Kleckner via Phabricator via cfe-commits]

rnk added a comment.

I'd rather avoid the ifdef if possible. I looked to see where these come from:

  $ git grep -l Distro ../clang/lib/Driver/
  ../clang/lib/Driver/CMakeLists.txt
  ../clang/lib/Driver/Distro.cpp
  ../clang/lib/Driver/ToolChains/Clang.cpp
  ../clang/lib/Driver/ToolChains/Cuda.cpp
  ../clang/lib/Driver/ToolChains/Linux.cpp

I think the only one that matters is in Clang.cpp, but it looks like it should never run on Windows:

  if (Args.hasFlag(options::OPT_faddrsig, options::OPT_fno_addrsig,
                   (TC.getTriple().isOSBinFormatELF() ||
                    TC.getTriple().isOSBinFormatCOFF()) &&
                      !TC.getTriple().isPS4() &&
                      !TC.getTriple().isOSNetBSD() &&
                      !Distro(D.getVFS()).IsGentoo() &&
                      !TC.getTriple().isAndroid() &&
                       TC.useIntegratedAs()))
    CmdArgs.push_back("-faddrsig");

Hm, I guess it does happen. I think that condition should be restructured to only do all that BSD, PS4, Android, Gentoo etc logic if the format is ELF, if COFF, then always default to -faddrsig.
