From dae4ac4fe56ec60fc93b3e3c9f51e79e682084b9 Mon Sep 17 00:00:00 2001 From: "Michael J. Spencer" Date: Thu, 21 Oct 2010 05:21:48 +0000 Subject: Reorganize predefined macros for all Windows targets. This adds an option to set the _MSC_VER macro without recompiling. This is very useful when testing compatibility with the Windows SDK and c++stdlib headers. -fmsc-version= (defaults to VS2003 (1300)) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116999 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Frontend/CompilerInvocation.cpp | 3 +++ 1 file changed, 3 insertions(+) (limited to 'lib/Frontend/CompilerInvocation.cpp') diff --git a/lib/Frontend/CompilerInvocation.cpp b/lib/Frontend/CompilerInvocation.cpp index b7ad08b8b2..3ed859a87b 100644 --- a/lib/Frontend/CompilerInvocation.cpp +++ b/lib/Frontend/CompilerInvocation.cpp @@ -529,6 +529,8 @@ static void LangOptsToArgs(const LangOptions &Opts, Res.push_back("-fgnu-keywords"); if (Opts.Microsoft) Res.push_back("-fms-extensions"); + if (Opts.MSCVersion != 0) + Res.push_back("-fmsc-version=" + llvm::utostr(Opts.MSCVersion)); if (Opts.Borland) Res.push_back("-fborland-extensions"); if (Opts.ObjCNonFragileABI) @@ -1334,6 +1336,7 @@ static void ParseLangArgs(LangOptions &Opts, ArgList &Args, InputKind IK, !Opts.AsmPreprocessor); Opts.PascalStrings = Args.hasArg(OPT_fpascal_strings); Opts.Microsoft = Args.hasArg(OPT_fms_extensions); + Opts.MSCVersion = Args.getLastArgIntValue(OPT_fmsc_version, 0, Diags); Opts.Borland = Args.hasArg(OPT_fborland_extensions); Opts.WritableStrings = Args.hasArg(OPT_fwritable_strings); Opts.ConstStrings = Args.hasArg(OPT_Wwrite_strings); -- cgit v1.2.3-70-g09d2
