From bf7fc9c542f2d7b47aaa5a387bbac5a25005c00e Mon Sep 17 00:00:00 2001 From: Douglas Gregor Date: Wed, 27 Mar 2013 16:47:18 +0000 Subject: Introduce -module-file-info option that provides information about a particular module file. This option can be useful for end users who want to know why they ended up with a ton of different variants of the "std" module in their module cache. This problem should go away over time, as we reduce the need for module variants, but it will never go away entirely. llvm-svn: 178148 --- clang/lib/Frontend/CompilerInvocation.cpp | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'clang/lib/Frontend/CompilerInvocation.cpp') diff --git a/clang/lib/Frontend/CompilerInvocation.cpp b/clang/lib/Frontend/CompilerInvocation.cpp index 2d945b5..0fb8e58 100644 --- a/clang/lib/Frontend/CompilerInvocation.cpp +++ b/clang/lib/Frontend/CompilerInvocation.cpp @@ -644,6 +644,8 @@ static InputKind ParseFrontendArgs(FrontendOptions &Opts, ArgList &Args, Opts.ProgramAction = frontend::InitOnly; break; case OPT_fsyntax_only: Opts.ProgramAction = frontend::ParseSyntaxOnly; break; + case OPT_module_file_info: + Opts.ProgramAction = frontend::ModuleFileInfo; break; case OPT_print_decl_contexts: Opts.ProgramAction = frontend::PrintDeclContext; break; case OPT_print_preamble: @@ -779,7 +781,7 @@ static InputKind ParseFrontendArgs(FrontendOptions &Opts, ArgList &Args, .Case("objective-c-header", IK_ObjC) .Case("c++-header", IK_CXX) .Case("objective-c++-header", IK_ObjCXX) - .Case("ast", IK_AST) + .Cases("ast", "pcm", IK_AST) .Case("ir", IK_LLVM_IR) .Default(IK_None); if (DashX == IK_None) @@ -1465,6 +1467,7 @@ static void ParsePreprocessorOutputArgs(PreprocessorOutputOptions &Opts, case frontend::GeneratePCH: case frontend::GeneratePTH: case frontend::ParseSyntaxOnly: + case frontend::ModuleFileInfo: case frontend::PluginAction: case frontend::PrintDeclContext: case frontend::RewriteObjC: @@ -1627,6 +1630,8 @@ llvm::APInt ModuleSignature::getAsInteger() const { } std::string CompilerInvocation::getModuleHash() const { + // Note: For QoI reasons, the things we use as a hash here should all be + // dumped via the -module-info flag. using llvm::hash_code; using llvm::hash_value; using llvm::hash_combine; -- cgit v1.1
