2013-03-13[Modules] Don't eagerly load and associate all the module header files.Argyrios Kyrtzidis
In a module-enabled Cocoa PCH file, we spend a lot of time stat'ing the headers in order to associate the FileEntries with their modules and support implicit module import. Use a more lazy scheme by enhancing HeaderInfoTable to store extra info about the module that a header belongs to, and associate it with its module only when there is a request for loading the header info for a particular file.

2012-06-22Documentation cleanup:James Dennett
* Primarily fixed \param commands with names not matching any actual parameters of the documented functions. In many cases this consists just of fixing up the parameter name in the \param to match the code, in some it means deleting obsolete documentation and occasionally it means documenting the parameter that has replaced the older one that was documented, which sometimes means some simple reverse-engineering of the docs from the implementation; * Fixed \param ParamName [out] to the correct format with [out] before the parameter name; * Fixed some \brief summaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158980 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-13More doxygen/documentation cleanups.James Dennett
This reduces the number of warnings generated by Doxygen by about 100 (roughly 10%). Issues addressed: (1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments when they're not supposed to be Doxygen commands or links, and similarly for "<baz>" when it's not intended as as HTML tag; (2) Changed some \t commands (which don't exist) to \c ("to refer to a word of code", as the Doxygen manual says); (3) \precondition becomes \pre; (4) When touching comments, deleted a couple of spurious spaces in them; (5) Changed some \n and \r to \\n and \\r; (6) Fixed one tiny typo: #pragms -> #pragma. This patch touches documentation/comments only. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158422 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-27Introduce module attributes into the module map grammar, along with aDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149143 91177308-0d34-0410-b5e6-96231b3b80d8
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
2011-12-09Move a free function from the Frontend library into the Lex library asChandler Carruth
part of HeaderSearch.

2011-11-30Promote ModuleMap::Module to a namespace-scope class in the BasicDouglas Gregor

2011-11-11Introduce basic support for parsing module map files.Douglas Gregor
Module map files provide a way to map between headers and modules, so that we can layer a module system on top of existing headers without changing those headers at all. This commit introduces the module map file parser and the module map that it generates, and wires up the module map file parser so that we'll automatically find module map files as part of header search. Note that we don't yet use the information stored in the module map. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144402 91177308-0d34-0410-b5e6-96231b3b80d8
