From ee977933f7df9cef13cc06ac7fa3e4a22b72e41f Mon Sep 17 00:00:00 2001 From: Richard Smith Date: Fri, 1 May 2015 21:22:17 +0000 Subject: [modules] Add -fmodules-local-submodule-visibility flag. This flag specifies that the normal visibility rules should be used even for local submodules (submodules of the currently-being-built module). Thus names will only be visible if a header / module that declares them has actually been included / imported, and not merely because a submodule that happened to be built earlier declared those names. This also removes the need to modularize bottom-up: textually-included headers will be included into every submodule that includes them, since their include guards will not leak between modules. So far, this only governs visibility of macros, not of declarations, so is not ready for real use yet. llvm-svn: 236350 --- clang/lib/Frontend/CompilerInvocation.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'clang/lib/Frontend/CompilerInvocation.cpp') diff --git a/clang/lib/Frontend/CompilerInvocation.cpp b/clang/lib/Frontend/CompilerInvocation.cpp index a91e31e36c1..79f80d0df74 100644 --- a/clang/lib/Frontend/CompilerInvocation.cpp +++ b/clang/lib/Frontend/CompilerInvocation.cpp @@ -1508,6 +1508,8 @@ static void ParseLangArgs(LangOptions &Opts, ArgList &Args, InputKind IK, Opts.ModulesStrictDeclUse = Args.hasArg(OPT_fmodules_strict_decluse); Opts.ModulesDeclUse = Args.hasArg(OPT_fmodules_decluse) || Opts.ModulesStrictDeclUse; + Opts.ModulesLocalVisibility = + Args.hasArg(OPT_fmodules_local_submodule_visibility); Opts.ModulesSearchAll = Opts.Modules && !Args.hasArg(OPT_fno_modules_search_all) && Args.hasArg(OPT_fmodules_search_all); -- cgit v1.2.3
