-ffinite-math-only. - No test case yet, I don't know how to construct a situation where this matters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146297 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-09Move ChainedIncludesSource into the Frontend library. This never reallyChandler Carruth
belonged in the Serialization library, it's setting up a compilation, not just deserializing. This should fix PR11512, making Serialization actually be layered below Frontend, a long standing layering violation in Clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146233 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-09Move a free function from the Frontend library into the Lex library asChandler Carruth
part of HeaderSearch. This function just normalizes filenames for use inside of a synthetic include directive, but it is used in both the Frontend and Serialization libraries so it needs a common home. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146227 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-08Implement umbrella directories for modules, which are similar toDouglas Gregor
umbrella headers in the sense that all of the headers within that directory (and eventually its subdirectories) are considered to be part of the module with that umbrella directory. However, unlike umbrella headers, which are expected to include all of the headers within their subdirectories, Clang will automatically include all of the headers it finds in the named subdirectory. The intent here is to allow a module map to trivially turn a subdirectory into a module, where the module's structure can mimic the directory structure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146165 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-08Within the module representation, generalize the notion of an umbrellaDouglas Gregor
header to also support umbrella directories. The umbrella directory for an umbrella header is the directory in which the umbrella header resides. No functionality change yet, but it's coming. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146158 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-08Keep track of import dependencies between submodules within the moduleDouglas Gregor
that's currently being built. This is important for supporting transitive dependencies ("export *" in the module map) completely. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146156 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-07Make changes to SDiagsWriter to make it work in combination with the ARC ↵Argyrios Kyrtzidis
migrator: -Allow it to be used with multiple BeginSourceFile/EndSourceFile calls; for this introduce a "finish" callback method in the DiagnosticConsumer. SDiagsWriter finishes up the serialization file inside this method. -Make it independent of any particular DiagnosticsEngine; make it use the SourceManager of the Diagnostic object. -Ignore null source ranges. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146020 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-07If we can't write the temporary module map file when compiling aDouglas Gregor
module, at least have the decency to complain about it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146002 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-06When building the main file to parse given a module map, don't skipDouglas Gregor
explicit submodules or umbrella headers from submodules. Instead, build the entire module at once, and let the name-hiding mechanisms hide the contents of explicit submodules at load time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145940 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-02When we treat an #include or #import as a module import, create anDouglas Gregor
implicit ImportDecl in the translation unit to record the presence of the import. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145727 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-01Introduce the notion of name visibility into modules. For a givenDouglas Gregor
(sub)module, all of the names may be hidden, just the macro names may be exposed (for example, after the preprocessor has seen the import of the module but the parser has not), or all of the names may be exposed. Importing a module makes its names, and the names in any of its non-explicit submodules, visible to name lookup (transitively). This commit only introduces the notion of name visible and marks modules and submodules as visible when they are imported. The actual name-hiding logic in the AST reader will follow (along with test cases). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145586 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-30Promote ModuleMap::Module to a namespace-scope class in the BasicDouglas Gregor
library, since modules cut across all of the libraries. Rename serialization::Module to serialization::ModuleFile to side-step the annoying naming conflict. Prune a bunch of ModuleMap.h includes that are no longer needed (most files only needed the Module type). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145538 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-30Implement (de-)serialization of the description of a module and itsDouglas Gregor
submodules. This information will eventually be used for name hiding when dealing with submodules. For now, we only use it to ensure that the module "key" returned when loading a module will always be a module (rather than occasionally being a FileEntry). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145497 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-30When writing a module file, pass the module through to the ASTDouglas Gregor
writer. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145479 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-30Teach the preprocessor how to handle module import declarations thatDouglas Gregor
involve submodules (e.g., importing std.vector), rather than always importing the top-level module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145478 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-30When loading a module that involves submodules (e.g., std.vector),Douglas Gregor
check whether the named submodules themselves are actually valid, and drill down to the named submodule (although we don't do anything with it yet). Perform typo correction on the submodule names when possible. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145477 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-30Switch the module-loading interfaces and parser from a simpleDouglas Gregor
top-level module name to a module path (e.g., std.vector). We're still missing a number of pieces for this actually to do something. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145462 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-29Eliminate the -emit-module option, which emitted a module by parsing aDouglas Gregor
source file (e.g., a header). Immediately steal this useful option name for building modules from a module map file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145444 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-29Switch on-demand module building over to use module maps, always. WhenDouglas Gregor
we infer the module map, we'll just print the module map to a temporary file and generate the module using that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145436 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-29Teach the module import mechanism how to rebuild modules expressed viaDouglas Gregor
module map, rather than assuming that there is an umbrella header. This allows us to automatically build umbrella-less modules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145415 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-29Start refactoring to use module maps when rebuilding a moduleDouglas Gregor
on-the-fly. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145414 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-28Add a couple more GCC versions to C++ search paths for MinGW. Patch by ↵Eli Friedman
Ruben Van Boxem. (We should probably start doing some sort of autodetection like we do on Linux at some point.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145326 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-28When attempting to load a module that is not in the module cache,Douglas Gregor
return the module itself (in the module map) rather than returning the umbrella header used to build the module. While doing this, make sure that we're inferring modules for frameworks to build that module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145310 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-23[libclang] Fix operations (token annotation, getting cursor, etc.) with a ↵Argyrios Kyrtzidis
file region inside an objc container that "contains" other file-level declarations. When getting the array of file-level declarations that overlap with a file region, we failed to report that the region overlaps with an objc container, if the container had other file-level declarations declared lexically inside it. Fix this by marking such declarations as "isTopLevelDeclInObjCContainer" in the AST and handling them appropriately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145109 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-21Add driver arguments -ftemplate-depth=N and -fconstexpr-depth=N, with the sameRichard Smith
semantics and defaults as the corresponding g++ arguments. The historical g++ argument -ftemplate-depth-N is kept for compatibility, but modern g++ versions no longer document that option. Add -cc1 argument -fconstexpr-depth N to implement the corresponding functionality. The -ftemplate-depth=N part of this fixes PR9890. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145045 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-18Refine placement of LangOptions object in CompilerInvocation by adding a new ↵Ted Kremenek
baseclass CompilerInvocationBase with a custom copy constructor. This ensures that whenever the CompilerInvocation object's copy constructor is used we always clone the LangOptions object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144973 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-18Change ASTConsumer::HandleTopLevelDecl to return true for the parser to continueArgyrios Kyrtzidis
parsing or false to abort parsing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144943 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-17Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted ↵Ted Kremenek
object. I discovered that llvm::RefCountedBase<T> has a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation objects created by ASTUnit were actually leaked. When I fixed that bug locally, it showed that a whole bunch of code assumed that the LangOptions object that was part of CompilerInvocation was still alive. By making it heap-allocated and reference counted, we can keep it around after the CompilerInvocation object goes away. As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this object may outlive the CompilerInvocation object. This commit doesn't fix the CompilerInvocation leak itself. That will come when I commit the fix to llvm::RefCountedBase<T> to mainline LLVM. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144930 91177308-0d34-0410-b5e6-96231b3b80d8
