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

#include "clang/AST/Decl.h"
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

Implemented an extension to the namespace map that permits a namespace map to be created and populated when the namespace is imported, not just when it is requested via FindExternalVisibleDecls(). llvm-svn: 142690

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.

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.

Implemented a namespace map that allows searching of namespaces (only in the modules where they've been found) for entities inside those namespaces. For each NamespaceDecl that has been imported into the parser, we maintain a map containing [ModuleSP, ClangNamespaceDecl] pairs in the ASTImporter. This map has one entry for each module in which the namespace has been found. When we later scan for an entity inside a namespace, we search only the modules in which that namespace was found. Also made a small whitespace fix in ClangExpressionParser.cpp. llvm-svn: 141748

to_interface_decl->setHasExternalVisibleStorage();
This patch modifies the expression parser to allow it to execute expressions even in the absence of a process. This allows expressions to run in situations where the target cannot run -- e.g., to perform calculations based on type information, or to inspect a binary's static data. This modification touches the following files: lldb-private-enumerations.h Introduce a new enum specifying the policy for processing an expression. Some expressions should always be JITted, for example if they are functions that will be used over and over again. Some expressions should always be interpreted, for example if the target is unsafe to run. For most, it is acceptable to JIT them, but interpretation is preferable when possible. Target.[h,cpp] Have EvaluateExpression now accept the new enum. ClangExpressionDeclMap.[cpp,h] Add support for the IR interpreter and also make the ClangExpressionDeclMap more robust in the absence of a process. ClangFunction.[cpp,h] Add support for the new enum. IRInterpreter.[cpp,h] New implementation. ClangUserExpression.[cpp,h] Add support for the new enum, and for running expressions in the absence of a process. ClangExpression.h Remove references to the old DWARF-based method of evaluating expressions, because it has been superseded for now. ClangUtilityFunction.[cpp,h] Add support for the new enum. ClangExpressionParser.[cpp,h] Add support for the new enum, remove references to DWARF, and add support for checking whether the expression could be evaluated statically. IRForTarget.[h,cpp] Add support for the new enum, and add utility functions to support the interpreter. IRToDWARF.cpp Removed CommandObjectExpression.cpp Remove references to the obsolete -i option. Process.cpp Modify calls to ClangUserExpression::Evaluate to pass the correct enum (for dlopen/dlclose) SBValue.cpp Add support for the new enum. SBFrame.cpp Add support for he new enum. BreakpointOptions.cpp Add support for the new enum. llvm-svn: 139772

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
