This commit adds broad architectural support for hierarchical inspection of namespaces in the expression parser. ClangExpressionDeclMap hitherto reported that namespaces had been completely imported, even though the namespaces are returned empty. To deal with this situation, ClangASTSource was recently extended with an API to complete incomplete type definitions, and, for greater efficiency, to complete these definitions partially, returning only those objects that have a given name. This commit supports these APIs on LLDB's side, and uses it to provide information on types resident in namespaces. Namespaces are now imported as they were -- that is to say, empty -- but with minimal import mode on. This means that Clang will come back and request their contents by name as needed. We now respond with information on the contained types; this will be followed soon by information on functions and variables. llvm-svn: 133852

This change brings in the latest LLVM/Clang, and completes the support in the LLDB expression parser for incomplete types. Clang now imports types lazily, and we complete those types as necessary. Changes include: - ClangASTSource now supports three APIs which it passes to ClangExpressionDeclMap. CompleteType completes a TagDecl or an ObjCInterfaceDecl when needed; FindExternalVisibleDecls finds named entities that are visible in the expression's scope; and FindExternalLexicalDecls performs a (potentially restricted) search for entities inside a lexical scope like a namespace. These changes mean that entities in namespaces should work normally. - The SymbolFileDWARF code for searching a context for a specific name is now more general, and can search arbitrary contexts. - We are continuing to adapt our calls into LLVM from interfaces that take start and end iterators when accepting multiple items to interfaces that use ArrayRef. - I have cleaned up some code, especially our use of namespaces. This change is neutral for our testsuite and greatly improves correctness for large programs (like Clang) with complicated type systems. It should also lay the groundwork for improving the expression parser's performance as we are lazier and lazier about providing type information. llvm-svn: 136555

clang::QualType
I made the ClangASTImporter owned by the target rather than individually on behalf of each ASTContext. This allows the ASTImporter to know about all containers of types, which will let it be smarter about forwarding information about type origins. That means that the following sequence of steps will be possible (after a few more changes): - Import a type from a Module's ASTContext into an expression parser ASTContext, tracking its origin information -- this works now. - Because the result of the expression uses that type, import it from the expression parser ASTContext into the Target's scratch AST context, forwarding the origin information -- this needs to be added. - For a later expression that uses the result, import the type from the Target's scratch AST context, still forwarding origin information -- this also needs to be added. - Use the intact origin information to complete the type as needed -- this works now if the origin information is present. To this end, I made the following changes: - ASTImporter top-level copy functions now require both a source and a destination AST context parameter. - The ASTImporter now knows how to purge records related to an ASTContext that is going away. - The Target now owns and creates the ASTImporter whenever the main executable changes or (in the absence of a main executable) on demand. llvm-svn: 144802

Fixed an issue that was causing us to crash when evaluating expressions for objective C or C++ methods when "self" or "this" were in scope, but had invalid locations in a DWARF location list. The lack of a valid value caused us to use an invalid type value and then we tried to import that invalid value and we would crash. llvm-svn: 134518

This commit supports these APIs on LLDB's side, and uses it to provide information on types resident in namespaces. Namespaces are now imported as they were -- that is to say, empty -- but with minimal import mode on. This means that Clang will come back and request their contents by name as needed. We now respond with information on the contained types; this will be followed soon by information on functions and variables. llvm-svn: 133852

This change brings in the latest LLVM/Clang, and completes the support in the LLDB expression parser for incomplete types. Clang now imports types lazily, and we complete those types as necessary. Changes include: - ClangASTSource now supports three APIs which it passes to ClangExpressionDeclMap. CompleteType completes a TagDecl or an ObjCInterfaceDecl when needed; FindExternalVisibleDecls finds named entities that are visible in the expression's scope; and FindExternalLexicalDecls performs a (potentially restricted) search for entities inside a lexical scope like a namespace. These changes mean that entities in namespaces should work normally. - The SymbolFileDWARF code for searching a context for a specific name is now more general, and can search arbitrary contexts. - We are continuing to adapt our calls into LLVM from interfaces that take start and end iterators when accepting multiple items to interfaces that use ArrayRef. - I have cleaned up some code, especially our use of namespaces. This change is neutral for our testsuite and greatly improves correctness for large programs (like Clang) with complicated type systems. It should also lay the groundwork for improving the expression parser's performance as we are lazier and lazier about providing type information. llvm-svn: 136555

This allows the ASTImporter to know about all containers of types, which will let it be smarter about forwarding information about type origins. That means that the following sequence of steps will be possible (after a few more changes): - Import a type from a Module's ASTContext into an expression parser ASTContext, tracking its origin information -- this works now. - Because the result of the expression uses that type, import it from the expression parser ASTContext into the Target's scratch AST context, forwarding the origin information -- this needs to be added. - For a later expression that uses the result, import the type from the Target's scratch AST context, still forwarding origin information -- this also needs to be added. - Use the intact origin information to complete the type as needed -- this works now if the origin information is present. To this end, I made the following changes: - ASTImporter top-level copy functions now require both a source and a destination AST context parameter. - The ASTImporter now knows how to purge records related to an ASTContext that is going away. - The Target now owns and creates the ASTImporter whenever the main executable changes or (in the absence of a main executable) on demand. llvm-svn: 144802

Fixed an issue that was causing us to crash when evaluating expressions for objective C or C++ methods when "self" or "this" were in scope, but had invalid locations in a DWARF location list. The lack of a valid value caused us to use an invalid type value and then we tried to import that invalid value and we would crash. llvm-svn: 134518

This change brings in the latest LLVM/Clang, and completes the support in the LLDB expression parser for incomplete types. Clang now imports types lazily, and we complete those types as necessary. Changes include: - ClangASTSource now supports three APIs which it passes to ClangExpressionDeclMap. CompleteType completes a TagDecl or an ObjCInterfaceDecl when needed; FindExternalVisibleDecls finds named entities that are visible in the expression's scope; and FindExternalLexicalDecls performs a (potentially restricted) search for entities inside a lexical scope like a namespace. These changes mean that entities in namespaces should work normally. - The SymbolFileDWARF code for searching a context for a specific name is now more general, and can search arbitrary contexts. - We are continuing to adapt our calls into LLVM from interfaces that take start and end iterators when accepting multiple items to interfaces that use ArrayRef. - I have cleaned up some code, especially our use of namespaces. This change is neutral for our testsuite and greatly improves correctness for large programs (like Clang) with complicated type systems. It should also lay the groundwork for improving the expression parser's performance as we are lazier and lazier about providing type information. llvm-svn: 136555

This commit completes the rearchitecting of ClangASTSource to allow variables in the persistent variable store to know how to complete themselves from debug information. That fixes a variety of bugs during dematerialization of expression results and also makes persistent variable and result variables ($foo, $4, ...) more useful. I have also added logging improvements that make it much easier to figure out how types are moving from place to place, and made some checking a little more aggressive. The commit includes patches to Clang which are currently being integrated into Clang proper; once these fixes are in Clang top-of-tree, these patches will be removed. The patches don't fix API; rather, they fix some internal bugs in Clang's ASTImporter that were exposed when LLDB was moving types from place to place multiple times. llvm-svn: 144969

Added support to the ASTImporter for passing completion information between different AST contexts. It works like this: - If a Decl is imported from a context that has completion metadata, then that Decl is associated with the same completion information (possibly none) as the Decl it was imported from. - If a Decl is imported from a context that does not have completion metadata, then it is marked as completable by consulting the Decl and context it was imported from. llvm-svn: 144838

Changed the ClangASTImporter to store metadata for each AST context it knows about in a single object. This makes it faster to look up the appropriate ASTImpoter for a given ASTContext pair and also makes it much easier to delete all metadata for a given AST context. In the future, this fix will allow the ClangASTImporter to propagate completion information between the metadata for different AST contexts as its minions move AST objects around. llvm-svn: 144835
2011-11-17 05:40:57 +08:00
Added support to the ASTImporter for passing completion information between different AST contexts. It works like this: - If a Decl is imported from a context that has completion metadata, then that Decl is associated with the same completion information (possibly none) as the Decl it was imported from. - If a Decl is imported from a context that does not have completion metadata, then it is marked as completable by consulting the Decl and context it was imported from. llvm-svn: 144838

This commit completes the rearchitecting of ClangASTSource to allow variables in the persistent variable store to know how to complete themselves from debug information. That fixes a variety of bugs during dematerialization of expression results and also makes persistent variable and result variables ($foo, $4, ...) more useful. I have also added logging improvements that make it much easier to figure out how types are moving from place to place, and made some checking a little more aggressive. The commit includes patches to Clang which are currently being integrated into Clang proper; once these fixes are in Clang top-of-tree, these patches will be removed. The patches don't fix API; rather, they fix some internal bugs in Clang's ASTImporter that were exposed when LLDB was moving types from place to place multiple times. llvm-svn: 144969

This change brings in the latest LLVM/Clang, and completes the support in the LLDB expression parser for incomplete types. Clang now imports types lazily, and we complete those types as necessary. Changes include: - ClangASTSource now supports three APIs which it passes to ClangExpressionDeclMap. CompleteType completes a TagDecl or an ObjCInterfaceDecl when needed; FindExternalVisibleDecls finds named entities that are visible in the expression's scope; and FindExternalLexicalDecls performs a (potentially restricted) search for entities inside a lexical scope like a namespace. These changes mean that entities in namespaces should work normally. - The SymbolFileDWARF code for searching a context for a specific name is now more general, and can search arbitrary contexts. - We are continuing to adapt our calls into LLVM from interfaces that take start and end iterators when accepting multiple items to interfaces that use ArrayRef. - I have cleaned up some code, especially our use of namespaces. This change is neutral for our testsuite and greatly improves correctness for large programs (like Clang) with complicated type systems. It should also lay the groundwork for improving the expression parser's performance as we are lazier and lazier about providing type information. llvm-svn: 136555

Pulled in a new version of LLVM/Clang to solve a variety of problems with Objective-C object completion. To go along with the LLVM/Clang-side fixes, we have a variety of Objective-C improvements. Fixes include: - It is now possible to run expressions when stopped in an Objective-C class method and have "self" act just like "self" would act in the class method itself (i.e., [self classMethod] works without casting the return type if debug info is present). To accomplish this, the expression masquerades as a class method added by a category. - Objective-C objects can now provide methods and properties and methods to Clang on demand (i.e., the ASTImporter sets hasExternalVisibleDecls on Objective-C interface objects). - Objective-C built-in types, which had long been a bone of contention (should we be using "id"? "id*"?), are now fetched correctly using accessor functions on ClangASTContext. We inhibit searches for them in the debug information. There are also a variety of logging fixes, and I made two changes to the test suite: - Enabled a test case for Objective-C properties in the current translation unit. - Added a test case for calling Objective-C class methods when stopped in a class method. llvm-svn: 144607

While tracking down memory consumption issue a few things were needed: the ability to dump more information about modules in "target modules list". We can now dump the shared pointer reference count for modules, the pointer to the module itself (in case performance tools can help track down who has references to said pointer), and the modification time. Added "target delete [target-idx ...]" to be able to delete targets when they are no longer needed. This will help track down memory usage issues and help to resolve when module ref counts keep getting incremented. If the command gets no arguments, the currently selected target will be deleted. If any arguments are given, they must all be valid target indexes (use the "target list" command to get the current target indexes). Took care of a bunch of "no newline at end of file" warnings. TimeValue objects can now dump their time to a lldb_private::Stream object. Modified the "target modules list --global" command to not error out if there are no targets since it doesn't require a target. Fixed an issue in the MacOSX DYLD dynamic loader plug-in where if a shared library was updated on disk, we would keep using the older one, even if it was updated. Don't allow the ModuleList::GetSharedModule(...) to return an empty module. Previously we could specify a valid path on disc to a module, and specify an architecture that wasn't contained in that module and get a shared pointer to a module that wouldn't be able to return an object file or a symbol file. We now make sure an object file can be extracted prior to adding the shared pointer to the module to get added to the shared list. llvm-svn: 137196
