2013-05-03When building a module, forward diagnostics to the outer diagnostic consumer.Douglas Gregor
Previously, we would clone the current diagnostic consumer to produce a new diagnostic consumer to use when building a module. The problem here is that we end up losing diagnostics for important diagnostic consumers, such as serialized diagnostics (where we'd end up with two diagnostic consumers writing the same output file). With forwarding, the diagnostics from all of the different modules being built get forwarded to the one serialized-diagnostic consumer and are emitted in a sane way. Fixes <rdar://problem/13663996>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181067 91177308-0d34-0410-b5e6-96231b3b80d8

least one of the macro definitions comes from a non-system header. This slightly weakens the heuristic introduced in r178109. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179411 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-27[modules] Before marking the module imported macros as ambiguous, check if ↵Argyrios Kyrtzidis
this is a case where the system macro uses a not identical definition compared to a macro from the clang headers. For example (these come from different modules): \#define LONG_MAX __LONG_MAX__ (clang's limits.h) \#define LONG_MAX 0x7fffffffffffffffL (system's limits.h) in which case don't mark them ambiguous to avoid the "ambiguous macro expansion" warning. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178109 91177308-0d34-0410-b5e6-96231b3b80d8

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.

2012-11-06Introduce inferred framework modules into the module map file,Douglas Gregor
allowing a module map to be placed one level above the '.framework' directories to specify that all .frameworks within that directory can be inferred as framework modules. One can also specifically exclude frameworks known not to work. This makes explicit (and more restricted) behavior modules have had "forever", where *any* .framework was assumed to be able to be built as a module. That's not necessarily true, so we white-list directories (with exclusions) when those directories have been audited. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167482 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-15Introduce the notion of excluded headers into the module mapDouglas Gregor
description. Previously, one could emulate this behavior by placing the header in an always-unavailable submodule, but Argyrios guilted me into expressing this idea properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165921 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-02Back out my heinous hack that tricked the module generation mechanismDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149611 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
2011-12-08Implement 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

2011-12-06Implement 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
2011-12-05When 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
2011-12-02Implementing parsing and resolution of module export declarationsDouglas Gregor

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

2011-11-17When we're loading a framework header, first try to turn the frameworkDouglas Gregor
into a module. This module can either be loaded from a module map in the framework directory (which isn't quite working yet) or inferred from an umbrella header (which does work, and replaces the existing hack). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144877 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-16A module with an umbrella header assumes that all of the headers inDouglas Gregor
the umbrella header's directory and its subdirectories are part of the module (that's why it's an umbrella). Make sure that these headers are considered to be part of the module for lookup purposes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144859 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-11Teach the search for modules to consider modules described by a moduleDouglas Gregor
map, so long as they have an umbrella header. This makes it possible to introduce a module map + umbrella header for a given set of headers, to turn it into a module. There are two major deficiencies here: first, we don't go hunting for module map files when we just see a module import (so we won't know about the modules described therein). Second, we don't yet have a way to build modules that don't have umbrella headers, or have incomplete umbrella headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144424 91177308-0d34-0410-b5e6-96231b3b80d8

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
