* <rdar://problem/13509689> Introduce -module-file-info option that provides ↵Douglas Gregor2013-03-271-0/+125
| | | | | | | | | | | 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
* [Modules] Resolve top-headers of modules lazily.Argyrios Kyrtzidis2013-03-131-3/+3
| | | | | | | | | | | This allows resolving top-header filenames of modules to FileEntries when we need them, not eagerly. Note that that this breaks ABI for libclang functions clang_Module_getTopLevelHeader / clang_Module_getNumTopLevelHeaders but this is fine because they are experimental and not widely used yet. llvm-svn: 176975
* Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth2012-12-041-4/+4
| | | | | | | | | | | | | uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. llvm-svn: 169237
* [modules] Use a memory buffer directly as input for the module includes,Argyrios Kyrtzidis2012-11-151-13/+5

* [modules] Consistently construct a buffer as input to build the module.Argyrios Kyrtzidis2012-10-101-82/+42

* Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie2012-03-111-1/+1
| | | | | | | | | | (Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner llvm-svn: 152536

| | | | | | | (I was going to fix the TODO about DenseMap too, but that would break self-host right now. See PR11922.) llvm-svn: 149799
* Back out my heinous hack that tricked the module generation mechanismDouglas Gregor2012-02-021-39/+26
| | | | | | | | | | | | | | | | | | | | into using non-absolute system includes (<foo>)... ... and introduce another hack that is simultaneously more heineous and more effective. We whitelist Clang-supplied headers that augment or override system headers (such as float.h, stdarg.h, and tgmath.h). For these headers, Clang does not provide a module mapping. Instead, a system-supplied module map can refer to these headers in a system module, and Clang will look both in its own include directory and wherever the system-supplied module map suggests, then adds either or both headers. The end result is that Clang-supplied headers get merged into the system-supplied module for the C standard library. As a drive-by, fix up a few dependencies in the _Builtin_instrinsics module. llvm-svn: 149611
* Split compiler builtin module into "stdlib" builtins and "intrinsic"Douglas Gregor2012-01-311-26/+39
| | | | | | | | builds, and bring mm_alloc.h into the fold. Start playing some tricks with these builtin modules to mirror the include_next tricks that the headers already perform. llvm-svn: 149434

* Rework HeaderSearch's interface for getting a module from a name andDouglas Gregor2012-01-291-1/+2
| | | | | | | | | for getting the name of the module file, unifying the code for searching for a module with a given name (into lookupModule()) and separating out the mapping to a module file (into getModuleFileName()). No functionality change. llvm-svn: 149197
* Introduce module attributes into the module map grammar, along with aDouglas Gregor2012-01-271-2/+4
| | | | | | | | | | | | | single attribute ("system") that allows us to mark a module as being a "system" module. Each of the headers that makes up a system module is considered to be a system header, so that we (for example) suppress warnings there. If a module is being inferred for a framework, and that framework directory is within a system frameworks directory, infer it as a system framework. llvm-svn: 149143

* Store the submodules of a module in source order, as they are storedDouglas Gregor2012-01-041-4/+3

* Implement support for module requirements, which indicate the languageDouglas Gregor2011-12-311-1/+15
| | | | | | | | | 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). llvm-svn: 147387

* Implement umbrella directories for modules, which are similar toDouglas Gregor2011-12-081-0/+23
| | | | | | | | | | | | | | | 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. llvm-svn: 146165
* Within the module representation, generalize the notion of an umbrellaDouglas Gregor2011-12-081-15/+20

* When building the main file to parse given a module map, don't skipDouglas Gregor2011-12-061-19/+24

* Promote ModuleMap::Module to a namespace-scope class in the BasicDouglas Gregor2011-11-301-2/+2

| | | | | | | | | | | include guards don't show up as macro definitions in every translation unit that imports a module. Macro definitions can, however, be exported with the intentionally-ugly #__export_macro__ directive. Implement this feature by not even bothering to serialize non-exported macros to a module, because clients of that module need not (should not) know that these macros even exist. llvm-svn: 138943

To bring back the AST printer, it needs to be: - Complete, covering all of C/C++/Objective-C - Documented, with appropriate Schema against which we can validate the output - Designed for C/C++/Objective-C, not Clang's specific ASTs - Stable across Clang versions - Well-tested llvm-svn: 127141

If a header file is not found at the path that we expect it to be and the PCH file was moved from its original location, try to resolve the file by assuming that header+PCH were moved together and the header is in the same place relative to the PCH. llvm-svn: 125576

I'm not sure if the goals are sufficiently aligned with the XML printer to allow a common implementation. Currently just falls back on the StmtDumper to display statements, which means it doesn't produce valid XML in those cases. llvm-svn: 120088
