Huge change to clean up types. A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error. This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@186130 91177308-0d34-0410-b5e6-96231b3b80d8

Added the ability to get a list of types from a SBModule or SBCompileUnit. Sebastien Metrot wanted this, and sent a hollowed out patch. I filled in the blanks and did the low level implementation. The new functions are: //------------------------------------------------------------------ /// Get all types matching \a type_mask from debug info in this /// module. /// /// @param[in] type_mask /// A bitfield that consists of one or more bits logically OR'ed /// together from the lldb::TypeClass enumeration. This allows /// you to request only structure types, or only class, struct /// and union types. Passing in lldb::eTypeClassAny will return /// all types found in the debug information for this module. /// /// @return /// A list of types in this module that match \a type_mask //------------------------------------------------------------------ lldb::SBTypeList SBModule::GetTypes (uint32_t type_mask) //------------------------------------------------------------------ /// Get all types matching \a type_mask from debug info in this /// compile unit. /// /// @param[in] type_mask /// A bitfield that consists of one or more bits logically OR'ed /// together from the lldb::TypeClass enumeration. This allows /// you to request only structure types, or only class, struct /// and union types. Passing in lldb::eTypeClassAny will return /// all types found in the debug information for this compile /// unit. /// /// @return /// A list of types in this compile unit that match \a type_mask //------------------------------------------------------------------ lldb::SBTypeList SBCompileUnit::GetTypes (uint32_t type_mask = lldb::eTypeClassAny); This lets you request types by filling out a mask that contains one or more bits from the lldb::TypeClass enumerations, so you can only get the types you really want. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@184251 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/12711206> Extending ValueObjectDynamicValue so that it stores a TypeAndOrName instead of a TypeSP. This change allows us to reflect the notion that a ValueObject can have a dynamic type for which we have no debug information. Previously, we would coalesce that to the static type of the object, potentially losing relevant information or even getting it wrong. This fix ensures we can correctly report the class name for Cocoa objects whose types are hidden classes that we know nothing about (e.g. __NSArrayI for immutable arrays). As a side effect, our --show-types argument to frame variable no longer needs to append custom dynamic type information. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@173216 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/11275622> Added new API to lldb::SBTypeMember for bitfields: bool SBTypeMember::IsBitfield(); uint32_t SBTypeMember::GetBitfieldSizeInBits(); Also added new properties for easy access. Now SBTypeMember objects in python have a "fields" property for all type fields, "bases" for all direct bases, "vbases" for all virtual base classes and "members" for a combo of all three organized by bit offset. They all return a python list() of SBTypeMember objects. Usage: (lldb) script >>> t = lldb.target.FindFirstType("my_type") >>> for field in t.fields: ... print field >>> for vbase in t.vbases: ... print vbase >>> for base in t.bases: ... print base >>> for member in t.members: ... print member Also added new "is_bitfield" property to the SBTypeMember objects that will return the result of SBTypeMember::IsBitfield(), and "bitfield_bit_size" which will return the result of SBTypeMember::GetBitfieldSizeInBits(); I also fixed "SBTypeMember::GetOffsetInBytes()" to return the correct byte offset. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@161091 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/11113279> Fixed type lookups to "do the right thing". Prior to this fix, looking up a type using "foo::bar" would result in a type list that contains all types that had "bar" as a basename unless the symbol file was able to match fully qualified names (which our DWARF parser does not). This fix will allow type matches to be made based on the basename and then have the types that don't match filtered out. Types by name can be fully qualified, or partially qualified with the new "bool exact_match" parameter to the Module::FindTypes() method. This fixes some issue that we discovered with dynamic type resolution as well as improves the overall type lookups in LLDB. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@153482 91177308-0d34-0410-b5e6-96231b3b80d8

Added support for looking up the complete type for Objective-C classes. This allows LLDB to find ivars declared in class extensions in modules other than where the debugger is currently stopped (we already supported this when the debugger was stopped in the same module as the definition). This involved the following main changes: - The ObjCLanguageRuntime now knows how to hunt for the authoritative version of an Objective-C type. It looks for the symbol indicating a definition, and then gets the type from the module containing that symbol. - ValueObjects now report their type with a potential override, and the override is set if the type of the ValueObject is an Objective-C class or pointer type that is defined somewhere other than the original reported type. This means that "frame variable" will always use the complete type if one is available. - The ClangASTSource now looks for the complete type when looking for ivars. This means that "expr" will always use the complete type if one is available. - I added a testcase that verifies that both "frame variable" and "expr" work. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@151214 91177308-0d34-0410-b5e6-96231b3b80d8

Removed all of the "#ifndef SWIG" from the SB header files since we are using interface (.i) files for each class. Changed the FindFunction class from: uint32_t SBTarget::FindFunctions (const char *name, uint32_t name_type_mask, bool append, lldb::SBSymbolContextList& sc_list) uint32_t SBModule::FindFunctions (const char *name, uint32_t name_type_mask, bool append, lldb::SBSymbolContextList& sc_list) To: lldb::SBSymbolContextList SBTarget::FindFunctions (const char *name, uint32_t name_type_mask = lldb::eFunctionNameTypeAny); lldb::SBSymbolContextList SBModule::FindFunctions (const char *name, uint32_t name_type_mask = lldb::eFunctionNameTypeAny); This makes the API easier to use from python. Also added the ability to append a SBSymbolContext or a SBSymbolContextList to a SBSymbolContextList. Exposed properties for lldb.SBSymbolContextList in python: lldb.SBSymbolContextList.modules => list() or all lldb.SBModule objects in the list lldb.SBSymbolContextList.compile_units => list() or all lldb.SBCompileUnits objects in the list lldb.SBSymbolContextList.functions => list() or all lldb.SBFunction objects in the list lldb.SBSymbolContextList.blocks => list() or all lldb.SBBlock objects in the list lldb.SBSymbolContextList.line_entries => list() or all lldb.SBLineEntry objects in the list lldb.SBSymbolContextList.symbols => list() or all lldb.SBSymbol objects in the list This allows a call to the SBTarget::FindFunctions(...) and SBModule::FindFunctions(...) and then the result can be used to extract the desired information: sc_list = lldb.target.FindFunctions("erase") for function in sc_list.functions: print function for symbol in sc_list.symbols: print symbol Exposed properties for the lldb.SBSymbolContext objects in python: lldb.SBSymbolContext.module => lldb.SBModule lldb.SBSymbolContext.compile_unit => lldb.SBCompileUnit lldb.SBSymbolContext.function => lldb.SBFunction lldb.SBSymbolContext.block => lldb.SBBlock lldb.SBSymbolContext.line_entry => lldb.SBLineEntry lldb.SBSymbolContext.symbol => lldb.SBSymbol Exposed properties for the lldb.SBBlock objects in python: lldb.SBBlock.parent => lldb.SBBlock for the parent block that contains lldb.SBBlock.sibling => lldb.SBBlock for the sibling block to the current block lldb.SBBlock.first_child => lldb.SBBlock for the first child block to the current block lldb.SBBlock.call_site => for inline functions, return a lldb.declaration object that gives the call site file, line and column lldb.SBBlock.name => for inline functions this is the name of the inline function that this block represents lldb.SBBlock.inlined_block => returns the inlined function block that contains this block (might return itself if the current block is an inlined block) lldb.SBBlock.range[int] => access the address ranges for a block by index, a list() with start and end address is returned lldb.SBBlock.ranges => an array or all address ranges for this block lldb.SBBlock.num_ranges => the number of address ranges for this blcok SBFunction objects can now get the SBType and the SBBlock that represents the top scope of the function. SBBlock objects can now get the variable list from the current block. The value list returned allows varaibles to be viewed prior with no process if code wants to check the variables in a function. There are two ways to get a variable list from a SBBlock: lldb::SBValueList SBBlock::GetVariables (lldb::SBFrame& frame, bool arguments, bool locals, bool statics, lldb::DynamicValueType use_dynamic); lldb::SBValueList SBBlock::GetVariables (lldb::SBTarget& target, bool arguments, bool locals, bool statics); When a SBFrame is used, the values returned will be locked down to the frame and the values will be evaluated in the context of that frame. When a SBTarget is used, global an static variables can be viewed without a running process. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@149853 91177308-0d34-0410-b5e6-96231b3b80d8

Switching back to using std::tr1::shared_ptr. We originally switched away due to RTTI worries since llvm and clang don't use RTTI, but I was able to switch back with no issues as far as I can tell. Once the RTTI issue wasn't an issue, we were looking for a way to properly track weak pointers to objects to solve some of the threading issues we have been running into which naturally led us back to std::tr1::weak_ptr. We also wanted the ability to make a shared pointer from just a pointer, which is also easily solved using the std::tr1::enable_shared_from_this class. The main reason for this move back is so we can start properly having weak references to objects. Currently a lldb_private::Thread class has a refrence to its parent lldb_private::Process. This doesn't work well when we now hand out a SBThread object that contains a shared pointer to a lldb_private::Thread as this SBThread can be held onto by external clients and if they end up using one of these objects we can easily crash. So the next task is to start adopting std::tr1::weak_ptr where ever it makes sense which we can do with lldb_private::Debugger, lldb_private::Target, lldb_private::Process, lldb_private::Thread, lldb_private::StackFrame, and many more objects now that they are no longer using intrusive ref counted pointer objects (you can't do std::tr1::weak_ptr functionality with intrusive pointers). git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@149207 91177308-0d34-0410-b5e6-96231b3b80d8

Discriminate between the lldb_private::Type's for ObjC Classes that come from debug info, and those that are made up from the ObjC runtime symbols. For now the latter contain nothing but the fact that the name describes an ObjC class, and so are not useful for things like dynamic types. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@148059 91177308-0d34-0410-b5e6-96231b3b80d8

Added a new class called lldb_private::SymbolFileType which is designed to take a SymbolFile reference and a lldb::user_id_t and be used in objects which represent things in debug symbols that have types where we don't need to know the true type yet, such as in lldb_private::Variable objects. This allows us to defer resolving the type until something is used. More specifically this allows us to get 1000 local variables from the current function, and if the user types "frame variable argc", we end up _only_ resolving the type for "argc" and not for the 999 other local variables. We can expand the use of this as needed in the future. Modified the DWARFMappedHash class to be able to read the HashData that has more than just the DIE offset. It currently will read the atoms in the header definition and read the data correctly. Currently only the DIE offset and type flags are supported. This is needed for adding type flags to the .apple_types hash accelerator tables. Fixed a assertion crash that would happen if we have a variable that had a DW_AT_const_value instead of a location where "location.LocationContains_DW_OP_addr()" would end up asserting when it tried to parse the variable location as a DWARF opcode list. Decreased the amount of memory that LLDB would use when evaluating an expression by 3x - 4x for clang. There was a place in the namespace lookup code that was parsing all namespaces with a certain name in a DWARF file instead of stopping when it found the first match. This was causing all of the compile units with a matching namespace to get parsed into memory and causing unnecessary memory bloat. Improved "Target::EvaluateExpression(...)" to not try and find a variable when the expression contains characters that would certainly cause an expression to need to be evaluated by the debugger. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@146130 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed the LLDB build so that we can have private types, private enums and public types and public enums. This was done to keep the SWIG stuff from parsing all sorts of enums and types that weren't needed, and allows us to abstract our API better. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@128239 91177308-0d34-0410-b5e6-96231b3b80d8

Clean up a bit of the type getting code where lldb_private:Type now has clang_type_t GetClangFullType(); // Get a completely defined clang type clang_type_t GetClangLayoutType(); // Get a clang type that can be used for type layout clang_type_t GetClangForwardType(); // A type that can be completed if needed, but is more efficient. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@125691 91177308-0d34-0410-b5e6-96231b3b80d8

A few of the issue I have been trying to track down and fix have been due to the way LLDB lazily gets complete definitions for types within the debug info. When we run across a class/struct/union definition in the DWARF, we will only parse the full definition if we need to. This works fine for top level types that are assigned directly to variables and arguments, but when we have a variable with a class, lets say "A" for this example, that has a member: "B *m_b". Initially we don't need to hunt down a definition for this class unless we are ever asked to do something with it ("expr m_b->getDecl()" for example). With my previous approach to lazy type completion, we would be able to take a "A *a" and get a complete type for it, but we wouldn't be able to then do an "a->m_b->getDecl()" unless we always expanded all types within a class prior to handing out the type. Expanding everything is very costly and it would be great if there were a better way. A few months ago I worked with the llvm/clang folks to have the ExternalASTSource class be able to complete classes if there weren't completed yet: class ExternalASTSource { .... virtual void CompleteType (clang::TagDecl *Tag); virtual void CompleteType (clang::ObjCInterfaceDecl *Class); }; This was great, because we can now have the class that is producing the AST (SymbolFileDWARF and SymbolFileDWARFDebugMap) sign up as external AST sources and the object that creates the forward declaration types can now also complete them anywhere within the clang type system. This patch makes a few major changes: - lldb_private::Module classes now own the AST context. Previously the TypeList objects did. - The DWARF parsers now sign up as an external AST sources so they can complete types. - All of the pure clang type system wrapper code we have in LLDB (ClangASTContext, ClangASTType, and more) can now be iterating through children of any type, and if a class/union/struct type (clang::RecordType or ObjC interface) is found that is incomplete, we can ask the AST to get the definition. - The SymbolFileDWARFDebugMap class now will create and use a single AST that all child SymbolFileDWARF classes will share (much like what happens when we have a complete linked DWARF for an executable). We will need to modify some of the ClangUserExpression code to take more advantage of this completion ability in the near future. Meanwhile we should be better off now that we can be accessing any children of variables through pointers and always be able to resolve the clang type if needed. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@123613 91177308-0d34-0410-b5e6-96231b3b80d8

First attempt and getting "const" C++ method function signatures correct. It currently isn't working, but it should be close. I will work on this more when I figure out what I am not doing correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@119324 91177308-0d34-0410-b5e6-96231b3b80d8

Modified the lldb_private::Type clang type resolving code to handle three cases when getting the clang type: - need only a forward declaration - need a clang type that can be used for layout (members and args/return types) - need a full clang type This allows us to partially parse the clang types and be as lazy as possible. The first case is when we just need to declare a type and we will complete it later. The forward declaration happens only for class/union/structs and enums. The layout type allows us to resolve the full clang type _except_ if we have any modifiers on a pointer or reference (both R and L value). In this case when we are adding members or function args or return types, we only need to know how the type will be laid out and we can defer completing the pointee type until we later need it. The last type means we need a full definition for the clang type. Did some renaming of some enumerations to get rid of the old "DC" prefix (which stands for DebugCore which is no longer around). Modified the clang namespace support to be almost ready to be fed to the expression parser. I made a new ClangNamespaceDecl class that can carry around the AST and the namespace decl so we can copy it into the expression AST. I modified the symbol vendor and symbol file plug-ins to use this new class. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@118976 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed an expression parsing issue where if you were stopped somewhere without debug information and you evaluated an expression, a crash would occur as a result of an unchecked pointer. Added the ability to get the expression path for a ValueObject. For a rectangle point child "x" the expression path would be something like: "rect.top_left.x". This will allow GUI and command lines to get ahold of the expression path for a value object without having to explicitly know about the hierarchy. This means the ValueObject base class now has a "ValueObject *m_parent;" member. All ValueObject subclasses now correctly track their lineage and are able to provide value expression paths as well. Added a new "--flat" option to the "frame variable" to allow for flat variable output. An example of the current and new outputs: (lldb) frame variable argc = 1 argv = 0x00007fff5fbffe80 pt = { x = 2 y = 3 } rect = { bottom_left = { x = 1 y = 2 } top_right = { x = 3 y = 4 } } (lldb) frame variable --flat argc = 1 argv = 0x00007fff5fbffe80 pt.x = 2 pt.y = 3 rect.bottom_left.x = 1 rect.bottom_left.y = 2 rect.top_right.x = 3 rect.top_right.y = 4 As you can see when there is a lot of hierarchy it can help flatten things out. Also if you want to use a member in an expression, you can copy the text from the "--flat" output and not have to piece it together manually. This can help when you want to use parts of the STL in expressions: (lldb) frame variable --flat argc = 1 argv = 0x00007fff5fbffea8 hello_world._M_dataplus._M_p = 0x0000000000000000 (lldb) expr hello_world._M_dataplus._M_p[0] == '\0' git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@116532 91177308-0d34-0410-b5e6-96231b3b80d8

Cleaned up a unused member variable in Debugger. Added the start of Host specific launch services, though it currently isn't hookup up to anything. We want to be able to launch a process and use the native launch services to launch an app like it would be launched by the user double clicking on the app. We also eventually want to be able to run a command line app in a newly spawned terminal to avoid terminal sharing. Fixed an issue with the new DWARF forward type declaration stuff. A crasher was found that was happening when trying to properly expand the forward declarations. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@115213 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed the forward declaration issue that was present in the DWARF parser after adding methods to C++ and objective C classes. In order to make methods, we need the function prototype which means we need the arguments. Parsing these could cause a circular reference that caused an assertion. Added a new typedef for the clang opaque types which are just void pointers: lldb::clang_type_t. This appears in lldb-types.h. This was fixed by enabling struct, union, class, and enum types to only get a forward declaration when we make the clang opaque qual type for these types. When they need to actually be resolved, lldb_private::Type will call a new function in the SymbolFile protocol to resolve a clang type when it is not fully defined (clang::TagDecl::getDefinition() returns NULL). This allows us to be a lot more lazy when parsing clang types and keeps down the amount of data that gets parsed into the ASTContext for each module. Getting the clang type from a "lldb_private::Type" object now takes a boolean that indicates if a forward declaration is ok: clang_type_t lldb_private::Type::GetClangType (bool forward_decl_is_ok); So function prototypes that define parameters that are "const T&" can now just parse the forward declaration for type 'T' and we avoid circular references in the type system. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@115012 91177308-0d34-0410-b5e6-96231b3b80d8

Change over to using the definitions for mach-o types and defines to the defines that are in "llvm/Support/MachO.h". This should allow ObjectFileMachO and ObjectContainerUniversalMachO to be able to be cross compiled in Linux. Also did some cleanup on the ASTType by renaming it to ClangASTType and renaming the header file. Moved a lot of "AST * + opaque clang type *" functionality from lldb_private::Type over into ClangASTType. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@109046 91177308-0d34-0410-b5e6-96231b3b80d8

Added function name types to allow us to set breakpoints by name more intelligently. The four name types we currently have are: eFunctionNameTypeFull = (1 << 1), // The function name. // For C this is the same as just the name of the function // For C++ this is the demangled version of the mangled name. // For ObjC this is the full function signature with the + or // - and the square brackets and the class and selector eFunctionNameTypeBase = (1 << 2), // The function name only, no namespaces or arguments and no class // methods or selectors will be searched. eFunctionNameTypeMethod = (1 << 3), // Find function by method name (C++) with no namespace or arguments eFunctionNameTypeSelector = (1 << 4) // Find function by selector name (ObjC) names this allows much more flexibility when setting breakoints: (lldb) breakpoint set --name main --basename (lldb) breakpoint set --name main --fullname (lldb) breakpoint set --name main --method (lldb) breakpoint set --name main --selector The default: (lldb) breakpoint set --name main will inspect the name "main" and look for any parens, or if the name starts with "-[" or "+[" and if any are found then a full name search will happen. Else a basename search will be the default. Fixed some command option structures so not all options are required when they shouldn't be. Cleaned up the breakpoint output summary. Made the "image lookup --address <addr>" output much more verbose so it shows all the important symbol context results. Added a GetDescription method to many of the SymbolContext objects for the more verbose output. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@107075 91177308-0d34-0410-b5e6-96231b3b80d8
