2011-12-31Implement support for module requirements, which indicate the languageDouglas Gregor
features needed for a particular module to be available. This allows mixed-language modules, where certain headers only work under some language variants (e.g., in C++, std.tuple might only be available in C++11 mode). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147387 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-23Mass rename C1x references to C11. The name hasn't proliferated like "C++0x" ↵Benjamin Kramer
so this patch is surprisingly small. Also drop -Wc1x-extensions in favor of -Wc11-extensions. I don't think we need to keep this around for compatibility. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147221 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-23When building a module with an umbrella header, warn about any headersDouglas Gregor
found within that umbrella directory that were not actually included by the umbrella header. They should either be referenced in the module map or included by the umbrella header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@147207 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-20Detect when mapping a #include/#import over to a submodule ends upDouglas Gregor
hitting a submodule that was never actually created, e.g., because that header wasn't parsed. In such cases, complain (because the module's umbrella headers don't cover everything) and fall back to including the header. Later, we'll add a warning at module-build time to catch all such cases. However, this fallback is important to eliminate assertions in the ASTWriter when this happens. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146933 91177308-0d34-0410-b5e6-96231b3b80d8

macro expansion. rdar://10588825 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146818 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-16Don't allow #include (and its friends #import, #include_next andRichard Smith
#__include_macros) in the arguments of a function-style macro. Directives in the arguments of such macros have undefined behaviour, and GCC does not correctly support these cases. In some situations, this can lead to better diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146765 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-12Set umbrella directory correctly when we infer a framework moduleDouglas Gregor

2011-12-12Don't mark include guard macros as implicitly private. This isn'tDouglas Gregor
actually a terribly good heuristic, and the world is too horrible for it to work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146393 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-09When performing subframework header lookup, don't search forDouglas Gregor
".framework/" in the path name, because it could be ".framework\" on Windows. This whole function needs to be rewritten with PathV2. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146261 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-09Implement the notion of umbrella directories, which implicity coverDouglas Gregor
all of the headers below that particular directory. Use umbrella directories as a clean way to deal with (1) directories/frameworks that don't have an umbrella header, but don't want to enumerate all of their headers, and (2) PrivateHeaders, which we never want to enumerate and want to keep separate from the main umbrella header. This also eliminates a little more of the "magic" for private headers, and frameworks in general. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146235 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
2011-12-08Tweak the syntax of umbrella headers, so that "umbrella" is treated asDouglas Gregor
a modifier for a header declarartion, e.g., umbrella header "headername" Collapse the umbrella-handling code in the parser into the header-handling code, so we don't duplicate the header-search logic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146159 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
2011-12-08Convert paths to native format before constructing aDouglas Gregor
directory_iterator for them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146154 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-07Implement inference for the "Private" submodule corresponding toDouglas Gregor
private headers in a framework. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146082 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-07Make sure we pick up module_private.map when loading a module.map file.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146074 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-07Implement basic support for private headers in frameworks. In essence,Douglas Gregor
when we load a module map (module.map) from a directory, also load a private module map (module_private.map) for that directory, if present. That private module map can inject a new submodule that captures private headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146012 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-06When inferring a module map for a framework, infer subframeworkDouglas Gregor

2011-12-06Allow inferred submodules for any (sub)module that has an umbrella headerDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145945 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06When suggesting a module import for a #include or #import, suggest theDouglas Gregor
most specific (sub)module based on the actual file we find, rather than always importing the top-level module. This means that #include'ing <Foo/Blah.h> should give us the submodule Foo.Blah. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145942 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06Implement modules support for subframeworks (aka embeddedDouglas Gregor
frameworks). A submodule can now be labeled as a "framework", and header search will look into the appropriate Headers/PrivateHeaders subdirectories for named headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145941 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06Minor tweak to prepare for submodules with umbrella headers. No actualDouglas Gregor

2011-12-06Implement inferred submodules support, which (when requested)Douglas Gregor
implicitly generates submodules corresponding to the headers that fall within a module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145887 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-05Inferred framework modules automatically export anything they importDouglas Gregor
(i.e., 'export *'), to better match the semantics of headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145813 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-05Implement support for wildcard exports in modules, allowing a moduleDouglas Gregor
to re-export anything that it imports. This opt-in feature makes a module behave more like a header, because it can be used to re-export the transitive closure of a (sub)module's dependencies. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145811 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-05When writing a module file, keep track of the set of (sub)modules thatDouglas Gregor
it imports, establishing dependencies at the (sub)module granularity. This is not a user-visible change (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145808 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-03Implement support for the __is_final type trait, to determine whetherDouglas Gregor
a class is marked 'final', from Alberto Ganesh Barbati! Fixes PR11462. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145775 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-02When we treat an #include or #import as a module import, create anDouglas Gregor

2011-12-02Implementing parsing and resolution of module export declarationsDouglas Gregor
within module maps, which will (eventually) be used to re-export a module from another module. There are still some pieces missing, however. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145665 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

2011-11-30Move the module auto-import logic after the logic that allows aDouglas Gregor
callback client to suggest an alternative search path and after we complain when the included file can't be found. The former can't be tested in isolation, the latter doesn't actually matter (because we won't make a module suggestion if no header is available). However, the flow is better this way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145502 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
