2011-09-12When an import statement fails to find a module in the module cache,Douglas Gregor
but there is a corresponding umbrella header in a framework, build the module on-the-fly so it can be immediately loaded at the import statement. This is very much proof-of-concept code, with details to be fleshed out over time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139558 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-12Introduce a cc1-level option to provide the path to the module cache,Douglas Gregor
where the compiler will look for module files. Eliminates the egregious hack where we looked into the header search paths for modules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139538 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Always construct an ASTReader with a non-NULL ASTContext andDouglas Gregor
Preprocessor, eliminating the constructor that was used by ASTUnit (which didn't provide an ASTContext or Prepreprocessor). Ensuring that both objects are non-NULL will simplify module loading (but none of that is done yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138986 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-02Extend the ASTContext constructor to delay the initialization ofDouglas Gregor
builtin types (When requested). This is another step toward making ASTUnit build the ASTContext as needed when loading an AST file, rather than doing so after the fact. No actual functionality change (yet). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138985 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Allow the preprocessor to be constructed without performing target-Douglas Gregor
and language-specific initialization. Use this to allow ASTUnit to create a preprocessor object *before* loading the AST file. No actual functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138983 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-31Switch the "no module found" default-fatal warning to a default-fatal error.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138909 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-26Introduce support for a simple module import declaration, whichDouglas Gregor
loads the named module. The syntax itself is intentionally hideous and will be replaced at some later point with something more palatable. For now, we're focusing on the semantics: - Module imports are handled first by the preprocessor (to get macro definitions) and then the same tokens are also handled by the parser (to get declarations). If both happen (as in normal compilation), the second one is redundant, because we currently have no way to hide macros or declarations when loading a module. Chris gets credit for this mad-but-workable scheme. - The Preprocessor now holds on to a reference to a module loader, which is responsible for loading named modules. CompilerInstance is the only important module loader: it now knows how to create and wire up an AST reader on demand to actually perform the module load. - We search for modules in the include path, using the module name with the suffix ".pcm" (precompiled module) for the file name. This is a temporary hack; we hope to improve the situation in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138679 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-25Introduce a -cc1 option "-emit-module", that creates a binary moduleDouglas Gregor
from the given source. -emit-module behaves similarly to -emit-pch, except that Sema is somewhat more strict about the contents of -emit-module. In the future, there are likely to be more interesting differences. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138595 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-28Cut down the number of open/close system calls for output files.Argyrios Kyrtzidis
For PCH files, have only one open/close for temporary + rename to be safe from race conditions. For all other output files open/close the output file directly.

2011-07-19Revamp the SourceManager to separate the representation of parsedDouglas Gregor
source locations from source locations loaded from an AST/PCH file. Previously, loading an AST/PCH file involved carefully pre-allocating space at the beginning of the source manager for the source locations and FileIDs that correspond to the prefix, and then appending the source locations/FileIDs used for parsing the remaining translation unit. This design forced us into loading PCH files early, as a prefix, whic has become a rather significant limitation. This patch splits the SourceManager space into two parts: for source location "addresses", the lower values (growing upward) are used to describe parsed code, while upper values (growing downward) are used for source locations loaded from AST/PCH files. Similarly, positive FileIDs are used to describe parsed code while negative FileIDs are used to file/macro locations loaded from AST/PCH files. As a result, we can load PCH/AST files even during parsing, making various improvemnts in the future possible, e.g., teaching #include <foo.h> to look for and load <foo.h.gch> if it happens to be already available. This patch was originally written by Sebastian Redl, then brought forward to the modern age by Jonathan Turner, and finally polished/finished by me to be committed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135484 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14NestedMacroInstantiations -> NestedMacroExpansionsChandler Carruth
This is switches all the interfaces points (and most of the commenst / local variables I saw on my way through) regarding the NestedMacroInstantiations bit. The libclang enums corresponding to this state were renamed, but a legacy enum was added with the old name, and the same value to keep existing clients working. I've added a documentation blurb for it, but let me know if there is a canonical way to document legacy elemenst of the libclang interface. No functionality changed here, even in tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135141 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-23avoid using config.h in public headersDylan Noblesmith
This is the only usage in clang's headers, and it's for a define that only exists on CMake builds for the sake of the MSVC compiler, so just use an ifdef instead. Also add an include for config.h in a file that actually needs it, and was picking it up by accident indirectly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133710 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-16Raise the ARCMT functionality in Clang into proper FrontendActions.Chandler Carruth
These are somewhat special in that they wrap any other FrontendAction, running various ARC transformations or checks prior to the standard action's run. To implement them easily, this extends FrontendAction to have a WrapperFrontendAction utility class which forwards all calls by default to an inner action setup at construction time. This is then subclassed to override the specific behavior needed by the different ARCMT tools. Finally, FrontendTool is taught how to create these wrapper actions from the existing flags and options structures. The result is that clangFrontend no longer depends on clangARCMigrate. This is very important, as clangARCMigrate *heavily* depends on clangFrontend. Fundamentally ARCMigrate is at the same layer as a library like Rewrite, sitting firmly on top of the Frontend, but tied together with the FrontendTool when building the clang binary itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133161 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-06Introduce a new libclang parsing flag,Douglas Gregor
CXTranslationUnit_NestedMacroInstantiations, which indicates whether we want to see "nested" macro instantiations (e.g., those that occur inside other macro instantiations) within the detailed preprocessing record. Many clients (e.g., those that only care about visible tokens) don't care about this information, and in code that uses preprocessor metaprogramming, this information can have a very high cost.

recovery. This was a huge resource "root" during crashes. This change requires making a bunch of fundamental Clang structures (optionally) reference counted to allow correct ownership semantics of these objects (e.g., ASTContext) to play out between an active ASTUnit and CompilerInstance object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128011 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-18Move CompilerInstance::LLVMContext and LLVMContext ownership to CodeGenActionPeter Collingbourne
This removes the final dependency edge from any lib outside of CodeGen to core. As a result we can, and do, trim the dependency on core from libclang, PrintFunctionNames, the unit tests and c-index-test. While at it, review and trim other unneeded dependencies. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125820 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-05Improve our uniquing of file entries when files are re-saved or areDouglas Gregor
overridden via remapping. Thus, when we create a "virtual" file in the file manager, we still stat() the real file that lives behind it so that we can provide proper uniquing based on inodes. This helps keep the file manager much more consistent. To take advantage of this when reparsing files in libclang, we disable the use of the stat() cache when reparsing or performing code completion, since the stat() cache is very likely to be out of date in this use case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124971 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-30When loading a precompiled preamble, use the file ID of theDouglas Gregor
precompiled preamble as the "main" source file's file ID within the source manager. This makes compiling with a precompiled preamble produce the same source locations as when compiling without the precompiled preamble; prior to this change, we ended up with different file IDs for source locations within the precompiled preamble vs. those after the precompiled preamble, even for entities (e.g., preprocessing entities) in the same file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120390 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03Implement -working-directory.Argyrios Kyrtzidis
When -working-directory is passed in command line, file paths are resolved relative to the specified directory. This helps both when using libclang (where we can't require the user to actually change the working directory) and to help reproduce test cases when the reproduction work comes along. --FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains the working directory value if set). --FileSystemOptions are passed around to various interfaces that perform file operations. --Opening & reading the content of files should be done only through FileManager. This is useful in general since file operations will be abstracted in the future for the reproduction mechanism. FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same FileManager but with different FileSystemOptions.
