From ba7f2f7110c201e3564e89bd306e058aa9c6b881 Mon Sep 17 00:00:00 2001 From: Daniel Jasper Date: Tue, 24 Sep 2013 09:14:14 +0000 Subject: Module use declarations (II) Review: http://llvm-reviews.chandlerc.com/D1546. I have picked up this patch form Lawrence (http://llvm-reviews.chandlerc.com/D1063) and did a few changes. From the original change description (updated as appropriate): This patch adds a check that ensures that modules only use modules they have so declared. To this end, it adds a statement on intended module use to the module.map grammar: use module-id A module can then only use headers from other modules if it 'uses' them. This enforcement is off by default, but may be turned on with the new option -fmodules-decluse. When enforcing the module semantics, we also need to consider a source file part of a module. This is achieved with a compiler option -fmodule-name=. The compiler at present only applies restrictions to the module directly being built. llvm-svn: 191283 --- clang/lib/Frontend/CompilerInvocation.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'clang/lib/Frontend/CompilerInvocation.cpp') diff --git a/clang/lib/Frontend/CompilerInvocation.cpp b/clang/lib/Frontend/CompilerInvocation.cpp index b13507a5ef1..c8c676899c5 100644 --- a/clang/lib/Frontend/CompilerInvocation.cpp +++ b/clang/lib/Frontend/CompilerInvocation.cpp @@ -1280,6 +1280,7 @@ static void ParseLangArgs(LangOptions &Opts, ArgList &Args, InputKind IK, Opts.Blocks = Args.hasArg(OPT_fblocks); Opts.BlocksRuntimeOptional = Args.hasArg(OPT_fblocks_runtime_optional); Opts.Modules = Args.hasArg(OPT_fmodules); + Opts.ModulesDeclUse = Args.hasArg(OPT_fmodules_decluse); Opts.CharIsSigned = Opts.OpenCL || !Args.hasArg(OPT_fno_signed_char); Opts.WChar = Opts.CPlusPlus && !Args.hasArg(OPT_fno_wchar); Opts.ShortWChar = Args.hasArg(OPT_fshort_wchar); -- cgit v1.2.3
