2011-12-06Remove misleading error messageDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145958 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-06When inferring a module map for a framework, infer subframeworkDouglas Gregor
modules for each of its subframeworks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145957 91177308-0d34-0410-b5e6-96231b3b80d8
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
2011-12-06Implement 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
functionality change yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145938 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
2011-12-05Parse inferred submodules in module maps, track their contents inDouglas Gregor
Module, and (de-)serialize this information. Semantics of inferred submodules to follow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145864 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
2011-12-02Implementing 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
2011-11-30Unbreak build with GCC. Clang is too lame to diagnose this particular ↵Douglas Gregor
ill-formedness git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145539 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
2011-11-30Use raw_ostream::indent.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145492 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-30Switch the module map printer over toDouglas Gregor
raw_ostream::write_escaped. Thanks, Benjamin! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145491 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-29Escape strings when printing module maps, for silly operating systemsDouglas Gregor
that use \ as a separator. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145439 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
2011-11-29Expose the printing of module maps as part of the ModuleMap::ModuleDouglas Gregor
interface. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145411 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-17Add the notion of "framework" modules to module maps. FrameworkDouglas Gregor
modules (obviously) describe frameworks, and understand the header layout of frameworks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144921 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-17Actually free memory for the module mapsDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144880 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
2011-11-13Silence unused variable warning.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144500 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
2011-11-11Wire up the mapping from header files mentioned in module maps over toDouglas Gregor
the corresponding (top-level) modules. This isn't actually useful yet, because we don't yet have a way to build modules out of module maps. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144410 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-11Resolve the header files named in module map "header" and "umbrella"Douglas Gregor
declarations to actual files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144408 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
