Modified the expression parser to only try to write to registers if they were modified in the expression. This eliminates spurious errors if the register can't be written to but the expression didn't write to it anyway. Also improved error handling for the materializer to make "couldn't materialize struct" errors more informative. <rdar://problem/14322579> git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@186228 91177308-0d34-0410-b5e6-96231b3b80d8

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

Performance optimizations to ClangUserExpression, mostly related to management of the stack frame for the interpreter. - First, if the expression can be interpreted, allocate the stack frame in the target process (to make sure pointers are valid) but only read/write to the copy in the host's memory. - Second, keep the memory allocations for the stack frame and the materialized struct as member variables of ClangUserExpression. This avoids memory allocations and deallocations each time the expression runs. <rdar://problem/13043685> git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@180664 91177308-0d34-0410-b5e6-96231b3b80d8

Optimized the way breakpoint conditions are evaluated. Previously, the options for a breakopint or its locations stored only the text of the breakpoint condition (ironically, they used ClangUserExpression as a glorified std::string) and, each time the condition had to be evaluated in the StopInfo code, the expression parser would be invoked via a static method to parse and then execute the expression. I made several changes here: - Each breakpoint location now has its own ClangUserExpressionSP containing a version of the breakpoint expression compiled for that exact location. - Whenever the breakpoint is hit, the breakpoint condition expression is simply re-run to determine whether to stop. - If the process changes (e.g., it's re-run) or the source code of the expression changes (we use a hash so as to avoid doing string comparisons) the ClangUserExpressionSP is re-generated. This should improve performance of breakpoint conditions significantly, and takes advantage of the recent expression re-use work. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@179838 91177308-0d34-0410-b5e6-96231b3b80d8

This commit changes the way LLDB executes user expressions. Previously, ClangUserExpression assumed that if there was a constant result for an expression then it could be determined during parsing. In particular, the IRInterpreter ran while parser state (in particular, ClangExpressionDeclMap) was present. This approach is flawed, because the IRInterpreter actually is capable of using external variables, and hence the result might be different each run. Until now, we papered over this flaw by re-parsing the expression each time we ran it. I have rewritten the IRInterpreter to be completely independent of the ClangExpressionDeclMap. Instead of special-casing external variable lookup, which ties the IRInterpreter closely to LLDB, we now interpret the exact same IR that the JIT would see. This IR assumes that materialization has occurred; hence the recent implementation of the Materializer, which does not require parser state (in the form of ClangExpressionDeclMap) to be present. Materialization, interpretation, and dematerialization are now all independent of parsing. This means that in theory we can parse expressions once and run them many times. I have three outstanding tasks before shutting this down: - First, I will ensure that all of this works with core files. Core files have a Process but do not allow allocating memory, which currently confuses materialization. - Second, I will make expression breakpoint conditions remember their ClangUserExpression and re-use it. - Third, I will tear out all the redundant code (for example, materialization logic in ClangExpressionDeclMap) that is no longer used. While implementing this fix, I also found a bug in IRForTarget's handling of floating-point constants. This should be fixed. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@179801 91177308-0d34-0410-b5e6-96231b3b80d8

Since we use C++11, we should switch over to using std::unique_ptr when C++11 is being used. To do this, we follow what we have done for shared pointers and we define a STD_UNIQUE_PTR macro that can be used and it will "do the right thing". Due to some API differences in std::unique_ptr and due to the fact that we need to be able to compile without C++11, we can't use move semantics so some code needed to change so that it can compile with either C++. Anyone wanting to use a unique_ptr or auto_ptr should now use the "STD_UNIQUE_PTR(TYPE)" macro. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@179779 91177308-0d34-0410-b5e6-96231b3b80d8

Flipped the big switch: LLDB now uses the new Materializer for all expressions that need to run in the target. This includes the following changes: - Removed a bunch of (de-)materialization code from ClangExpressionDeclMap and assumed the presence of a Materializer where we previously had a fallback. - Ensured that an IRMemoryMap is passed into ClangExpressionDeclMap::Materialize(). - Fixed object ownership on LLVMContext; it is now owned by the IRExecutionUnit, since the Module and the ExecutionEngine both depend on its existence. - Fixed a few bugs in IRMemoryMap and the Materializer that showed up during testing. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@179649 91177308-0d34-0410-b5e6-96231b3b80d8

Factored out memory access into the target process from IRExecutionUnit into a superclass called IRMemoryMap. IRMemoryMap handles all reading and writing, ensuring that areas are kept track of and memory is properly cached (and deleted). Also fixed several cases where we would simply leak binary data in the target process over time. Now the expression objects explicitly own their IRExecutionUnit and delete it when they go away. This is why I had to modify ClangUserExpression, ClangUtilityFunction, and ClangFunction. As a side effect of this, I am removing the JIT mutex for an IRMemoryMap. If it turns out that we need this mutex, I'll add it in then, but right now it's just adding complexity. This is part of a more general project to make expressions fully reusable. The next step is to make materialization and dematerialization use the IRMemoryMap API rather than writing and reading directly from the process's memory. This will allow the IR interpreter to use the same data, but in the host's memory, without having to use a different set of pointers. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@178832 91177308-0d34-0410-b5e6-96231b3b80d8

Refactored the expression parser so that the IR and the JITted code are managed by a standalone class that handles memory management itself. I have removed RecordingMemoryManager and ProcessDataAllocator, which filled similar roles and had confusing ownership, with a common class called IRExecutionUnit. The IRExecutionUnit manages all allocations ever made for an expression and frees them when it goes away. It also contains the code generator and can vend the Module for an expression to other clases. The end goal here is to make the output of the expression parser re-usable; that is, to avoid re-parsing when re-parsing isn't necessary. I've also cleaned up some code and used weak pointers in more places. Please let me know if you see any leaks; I checked myself as well but I might have missed a case. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@177364 91177308-0d34-0410-b5e6-96231b3b80d8

Separated the "expr --unwind-on-error" behavior into two parts, actual errors (i.e. crashes) which continue to be controlled by the --unwind-on-error flag, and --ignore-breakpoint which separately controls behavior when a called function hits a breakpoint. For breakpoints, we don't unwind, we either stop, or ignore the breakpoint, which makes more sense. Also make both these behaviors globally settable through "settings set". Also handle the case where a breakpoint command calls code that ends up re-hitting the breakpoint. We were recursing and crashing. Now we just stop without calling the second command. <rdar://problem/12986644> <rdar://problem/9119325> git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@172503 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/11757916> Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes: - Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". - modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly - Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was. - modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile() Cleaned up header includes a bit as well. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@162860 91177308-0d34-0410-b5e6-96231b3b80d8

<rdar://problem/10103468> I started work on being able to add symbol files after a debug session had started with a new "target symfile add" command and quickly ran into problems with stale Address objects in breakpoint locations that had lldb_private::Section pointers into modules that had been removed or replaced. This also let to grabbing stale modules from those sections. So I needed to thread harded the Address, Section and related objects. To do this I modified the ModuleChild class to now require a ModuleSP on initialization so that a weak reference can created. I also changed all places that were handing out "Section *" to have them hand out SectionSP. All ObjectFile, SymbolFile and SymbolVendors were inheriting from ModuleChild so all of the find plug-in, static creation function and constructors now require ModuleSP references instead of Module *. Address objects now have weak references to their sections which can safely go stale when a module gets destructed. This checkin doesn't complete the "target symfile add" command, but it does get us a lot clioser to being able to do such things without a high risk of crashing or memory corruption. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@151336 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed a bunch of ownership problems with the expression parser. Specifically: - ClangUserExpression now keeps weak pointers to the structures it needs and then locks them when needed. This ensures that they continue to be valid without leaking memory if the ClangUserExpression is long lived. - ClangExpressionDeclMap, instead of keeping a pointer to an ExecutionContext, now contains an ExecutionContext. This prevents bugs if the pointer or its contents somehow become stale. It also no longer requires that ExecutionContexts be passed into any function except its initialization function, since it can count on the ExecutionContext still being around. There's a lot of room for improvement (specifically, ClangExpressionDeclMap should also use weak pointers insetad of shared pointers) but this is an important first step that codifies assumptions that already existed in the code. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@150217 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

The "desired result type" code in the expression parser has hitherto been an implementation waiting for a use. I have now tied the '-o' option for the expression command -- which indicates that the result is an Objective-C object and needs to be printed -- to the ExpressionParser, which communicates the desired type to Clang. Now, if the result of an expression is determined by an Objective-C method call for which there is no type information, that result is implicitly cast to id if and only if the -o option is passed to the expression command. (Otherwise if there is no explicit cast Clang will issue an error. This behavior is identical to what happened before r146756.) Also added a testcase for -o enabled and disabled. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@147099 91177308-0d34-0410-b5e6-96231b3b80d8

This commit is the result of a general audit of the expression parser to locate instances where dyn_cast<>() and isa<>() are used on types, and replace them with getAs<>() as appropriate. The difference is that dyn_cast<>() and isa<>() are essentially LLVM/Clang's equivalent of RTTI -- that is, they try to downcast the object and return NULL if they cannot -- but getAs<>() can traverse typedefs to perform a semantic cast. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@146537 91177308-0d34-0410-b5e6-96231b3b80d8

I have modified the part of the code that finds and validates the "self," "this," and "_cmd" pointers that get passed into expressions. It used to check them aggressively for validity before allowing the expression to run as an object method; now, this functionality is gated by a bool and off by default. Now the default is that when LLDB is stopped in a method of a class, code entered using "expr" will always masquerade as an instance method. If for some reason "self," "this," or "_cmd" is unavailable it will be reported as NULL. This may cause the expression to crash if it relies on those pointers, but for example getting the addresses of ivars will now work as the user would expect. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@146465 91177308-0d34-0410-b5e6-96231b3b80d8

As part of the work to make Objective-C type information from symbols more accessible, I have added a second map to the ClangASTImporter: the ObjCInterfaceMetaMap. This map keeps track of all type definitions found for a particular Objective-C interface, allowing the ClangASTSource to refer to all possible sources when looking for method definitions. There is a bug in lookup that I still need to figure out, but after that we should be able to report full method information for Objective-C classes shown in symbols. Also fixed some errors I ran into when enabling the maps for the persistent type store. The persistent type store previously did not use the ClangASTImporter to import types, instead using ASTImporters that got allocated each time a type needed copying. To support the requirements of the persistent type store -- namely, that types must be copied, completed, and then completely severed from their origin in the parser's AST context (which will go away) -- I added a new function called DeportType which severs all these connections. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@145914 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@144607 91177308-0d34-0410-b5e6-96231b3b80d8

Occasionally LLDB runs into contexts where the target is stopped in a C++ or Objective-C method but the "self" pointer's valid range actually doesn't cover the current location. Before, that was confusing Clang to the point where it crashed; now, we sanity-check and fall back to pretending we're in a C function if "self" or "this" isn't available. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@143676 91177308-0d34-0410-b5e6-96231b3b80d8

Converted the lldb_private::Process over to use the intrusive shared pointers. Changed the ExecutionContext over to use shared pointers for the target, process, thread and frame since these objects can easily go away at any time and any object that was holding onto an ExecutionContext was running the risk of using a bad object. Now that the shared pointers for target, process, thread and frame are just a single pointer (they all use the instrusive shared pointers) the execution context is much safer and still the same size. Made the shared pointers in the the ExecutionContext class protected and made accessors for all of the various ways to get at the pointers, references, and shared pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@140298 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@139772 91177308-0d34-0410-b5e6-96231b3b80d8

Huge memory and performance improvements in the DWARF parser. Address ranges are now split up into two different tables: - one in DWARFDebugInfo that is compile unit specific - one in each DWARFCompileUnit that has exact function DIE offsets This helps keep the size of the aranges down since the main table will get uniqued and sorted and have consecutive ranges merged. We then only parse the compile unit one on demand once we have determined that a compile unit contains the address in question. We also now use the .debug_aranges section if there is one instead of always indexing the DWARF manually. NameToDIE now uses a UniqueCStringMap<dw_offset> map instead of a std::map. std::map is very bulky as each node has 3 pointers and the key and value types. This gets our NameToDIE entry down to 12 bytes each instead of 48 which saves us a lot of memory when we have very large DWARF. DWARFDebugAranges now has a smaller footprint for each range it contains to save on memory. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@139557 91177308-0d34-0410-b5e6-96231b3b80d8

You can use a persistent type like this: (lldb) expr struct $foo { int a; int b; }; (lldb) struct $foo i; i.a = 2; i.b = 3; i ($foo) $0 = { (int) a = 2 (int) b = 3 } typedefs work similarly. This patch affects the following files: test/expression_command/persistent_types/* A test case for persistent types, in particular structs and typedefs. ClangForward.h Added TypeDecl, needed to declare some functions in ASTResultSynthesizer.h ClangPersistentVariables.[h,cpp] Added a list of persistent types to the persistent variable store. ASTResultSynthesizer.[h,cpp] Made the AST result synthesizer iterate across TypeDecls in the expression, and record any persistent types found. Also made a minor documentation fix. ClangUserExpression.[h,cpp] Extended the user expression class to keep the state needed to report the persistent variable store for the target to the AST result synthesizers. Also introduced a new error code for expressions that executed normally but did not return a result. CommandObjectExpression.cpp Improved output for expressions (like declarations of new persistent types) that don't return a result. This is no longer treated as an error. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@138383 91177308-0d34-0410-b5e6-96231b3b80d8

This is an overhaul of the expression parser code that detects what context the current expression is meant to execute in. LLDB now properly consults the method declaration in the debug information rather than trying to hunt down the "this" or "self" pointer by name, which can be misleading. Other fixes include: - LLDB now properly detects that it is inside an inlined C++ member function. - LLDB now allows access to non-const members when in const code. - The functions in SymbolFile that locate the DeclContext containing a DIE have been renamed to reflect what they actually do. I have added new functions that find the DeclContext for the DIE itself. I have also introduced testcases for C++ and Objective-C. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@136999 91177308-0d34-0410-b5e6-96231b3b80d8

Improved the expression parser's detection of the current context. Previously, if there was a variable called "self" available, the expression parser assumed it was inside a method. But class methods in Objective-C also take a "self" parameter, of DWARF type "id". We now detect this properly, and only assume we're in an instance method if "self" is a pointer to an Objective-C object. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@136784 91177308-0d34-0410-b5e6-96231b3b80d8

The implementation of categories is now synchronization safe Code cleanup: - The Format Manager implementation is now split between two files: FormatClasses.{h|cpp} where the actual formatter classes (ValueFormat, SummaryFormat, ...) are implemented and FormatManager.{h|cpp} where the infrastructure classes (FormatNavigator, FormatManager, ...) are contained. The wrapper code always remains in Debugger.{h|cpp} - Several leftover fields, methods and comments from previous design choices have been removed type category subcommands (enable, disable, delete) now can take a list of category names as input - for type category enable, saying "enable A B C" is the same as saying enable C enable B enable A (the ordering is relevant in enabling categories, and it is expected that a user typing enable A B C wants to look into category A, then into B, then into C and not the other way round) - for the other two commands, the order is not really relevant (however, the same inverted ordering is used for consistency) git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@135494 91177308-0d34-0410-b5e6-96231b3b80d8

This commit integrates support for the LLVM MCJIT into the mainline LLDB codebase. MCJIT introduces API improvements and better architectural support. This commit adds a new subsystem, the ProcessDataAllocator, which is responsible for performing static data allocations on behalf of the IR transformer. MCJIT currently does not support the relocations required to store the constant pool in the same allocation as the function body, so we allocate a heap region separately and redirect static data references from the expression to that heap region in a new IR modification pass. This patch also fixes bugs in the IR transformations that were exposed by the transition to the MCJIT. Finally, the patch also pulls in a more recent revision of LLVM so that the MCJIT is available for use. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@131923 91177308-0d34-0410-b5e6-96231b3b80d8

Thread safety changes in debugserver and also in the process GDB remote plugin. I added support for asking if the GDB remote server supports thread suffixes for packets that should be thread specific (register read/write packets) because the way the GDB remote protocol does it right now is to have a notion of a current thread for register and memory reads/writes (set via the "$Hg%x" packet) and a current thread for running ("$Hc%x"). Now we ask the remote GDB server if it supports adding the thread ID to the register packets and we enable that feature in LLDB if supported. This stops us from having to send a bunch of packets that update the current thread ID to some value which is prone to error, or extra packets. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@123762 91177308-0d34-0410-b5e6-96231b3b80d8

Implemented a major overhaul of the way variables are handled by LLDB. Instead of being materialized into the input structure passed to the expression, variables are left in place and pointers to them are materialzied into the structure. Variables not resident in memory (notably, registers) get temporary memory regions allocated for them. Persistent variables are the most complex part of this, because they are made in various ways and there are different expectations about their lifetime. Persistent variables now have flags indicating their status and what the expectations for longevity are. They can be marked as residing in target memory permanently -- this is the default for result variables from expressions entered on the command line and for explicitly declared persistent variables (but more on that below). Other result variables have their memory freed. Some major improvements resulting from this include being able to properly take the address of variables, better and cleaner support for functions that return references, and cleaner C++ support in general. One problem that remains is the problem of explicitly declared persistent variables; I have not yet implemented the code that makes references to them into indirect references, so currently materialization and dematerialization of these variables is broken. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@123371 91177308-0d34-0410-b5e6-96231b3b80d8

Implemented a feature where the expression parser can avoid running the code in the target if the expression's result is known and the expression has no side effects.

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@121745 91177308-0d34-0410-b5e6-96231b3b80d8

Bugfixes for the new "self" pointer handling. Specifically, the code to pass the _cmd pointer has been improved, and _cmd is now set to the value of _cmd for the current context, as opposed to being simply NULL. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@121739 91177308-0d34-0410-b5e6-96231b3b80d8

Added support for generating expressions that have access to the members of the Objective-C self object. The approach we take is to generate the method as a @category on top of the self object, and to pass the "self" pointer to it. (_cmd is currently NULL.) Most changes are in ClangExpressionDeclMap, but the change that adds support to the ABIs to pass _cmd touches a fair amount of code. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@121722 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed object lifetimes in ClangExpressionDeclMap so that it is not referring to potentially stale state during IR execution. This was done by introducing modular state (like ClangExpressionVariable) where groups of state variables have well-defined lifetimes: - m_parser_vars are specific to parsing, and only exist between calls to WillParse() and DidParse(). - m_struct_vars survive for the entire execution of the ClangExpressionDeclMap because they provide the template for a materialized set of expression variables. - m_material_vars are specific to a single instance of materialization, and only exist between calls to Materialize() and Dematerialize(). I also removed unnecessary references to long- lived state that really didn't need to be referred to at all, and also introduced several assert()s that helped me diagnose a few bugs (fixed too). git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@120778 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed ClangUserExpression's wrapping of expressions in C++ methods.

Moved the code in ClangUserExpression that set up & ran the thread plan with timeouts, and restarting with all threads into a utility function in Process. This required a bunch of renaming. Added a ThreadPlanCallUserExpression that differs from ThreadPlanCallFunction in that it holds onto a shared pointer to its ClangUserExpression so that can't go away before the thread plan is done using it. Fixed the stop message when you hit a breakpoint while running a user expression so it is more obvious what has happened. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@120386 91177308-0d34-0410-b5e6-96231b3b80d8

Modified all logging calls to hand out shared pointers to make sure we don't crash if we disable logging when some code already has a copy of the logger. Prior to this fix, logs were handed out as pointers and if they were held onto while a log got disabled, then it could cause a crash. Now all logs are handed out as shared pointers so this problem shouldn't happen anymore. We are also using our new shared pointers that put the shared pointer count and the object into the same allocation for a tad better performance. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@118319 91177308-0d34-0410-b5e6-96231b3b80d8

Added support for loading and unloading shared libraries. This was done by adding support into lldb_private::Process: virtual uint32_t lldb_private::Process::LoadImage (const FileSpec &image_spec, Error &error); virtual Error lldb_private::Process::UnloadImage (uint32_t image_token); There is a default implementation that should work for both linux and MacOSX. This ability has also been exported through the SBProcess API: uint32_t lldb::SBProcess::LoadImage (lldb::SBFileSpec &image_spec, lldb::SBError &error); lldb::SBError lldb::SBProcess::UnloadImage (uint32_t image_token); Modified the DynamicLoader plug-in interface to require it to be able to tell us if it is currently possible to load/unload a shared library: virtual lldb_private::Error DynamicLoader::CanLoadImage () = 0; This way the dynamic loader plug-ins are allows to veto whether we can currently load a shared library since the dynamic loader might know if it is currenlty loading/unloading shared libraries. It might also know about the current host system and know where to check to make sure runtime or malloc locks are currently being held. Modified the expression parser to have ClangUserExpression::Evaluate() be the one that causes the dynamic checkers to be loaded instead of other code that shouldn't have to worry about it. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@118227 91177308-0d34-0410-b5e6-96231b3b80d8

Added a user-settable variable, 'target.expr-prefix', which holds the name of a file whose contents are prefixed to each expression. For example, if the file ~/lldb.prefix.header contains: typedef unsigned short my_type; then you can do this: (lldb) settings set target.expr-prefix '~/lldb.prefix.header' (lldb) expr sizeof(my_type) (unsigned long) $0 = 2 When the variable is changed, the corresponding file is loaded and its contents are fetched into a string that is stored along with the target. This string is then passed to each expression and inserted into it during parsing, like this: typedef unsigned short my_type; void $__lldb_expr(void *$__lldb_arg) { sizeof(my_type); } git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@117627 91177308-0d34-0410-b5e6-96231b3b80d8

Updated the lldb_private::Flags class to have better method names and made all of the calls inlined in the header file for better performance. Fixed the summary for C string types (array of chars (with any combo if modifiers), and pointers to chars) work in all cases. Fixed an issue where a forward declaration to a clang type could cause itself to resolve itself more than once if, during the resolving of the type itself it caused something to try and resolve itself again. We now remove the clang type from the forward declaration map in the DWARF parser when we start to resolve it and avoid this additional call. This should stop any duplicate members from appearing and throwing all the alignment of structs, unions and classes. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@117437 91177308-0d34-0410-b5e6-96231b3b80d8

Made many ConstString functions inlined in the header file. Changed all of our synthesized "___clang" functions, types and variables that get used in expressions over to have a prefix of "$_lldb". Now when we do name lookups we can easily switch off of the first '$' character to know if we should look through only our internal (when first char is '$') stuff, or when we should look through program variables, functions and types. Converted all of the clang expression code over to using "const ConstString&" values for names instead of "const char *" since there were many places that were converting the "const char *" names into ConstString names and them throwing them away. We now avoid making a lot of ConstString conversions and benefit from the quick comparisons in a few extra spots. Converted a lot of code from LLVM coding conventions into LLDB coding conventions. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@116634 91177308-0d34-0410-b5e6-96231b3b80d8

Added the notion that a value object can be constant by adding: bool ValueObject::GetIsConstant() const; void ValueObject::SetIsConstant(); This will stop anything from being re-evaluated within the value object so that constant result value objects can maintain their frozen values without anything being updated or changed within the value object. Made it so the ValueObjectConstResult can be constructed with an lldb_private::Error object to allow for expression results to have errors. Since ValueObject objects contain error objects, I changed the expression evaluation in ClangUserExpression from static Error ClangUserExpression::Evaluate (ExecutionContext &exe_ctx, const char *expr_cstr, lldb::ValueObjectSP &result_valobj_sp); to: static lldb::ValueObjectSP Evaluate (ExecutionContext &exe_ctx, const char *expr_cstr); Even though expression parsing is borked right now (pending fixes coming from Sean Callanan), I filled in the implementation for: SBValue SBFrame::EvaluateExpression (const char *expr); Modified all expression code to deal with the above changes. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@115589 91177308-0d34-0410-b5e6-96231b3b80d8

Removed the hacky "#define this ___clang_this" handler for C++ classes. Replaced it with a less hacky approach: - If an expression is defined in the context of a method of class A, then that expression is wrapped as ___clang_class::___clang_expr(void*) { ... } instead of ___clang_expr(void*) { ... }. - ___clang_class is resolved as the type of the target of the "this" pointer in the method the expression is defined in. - When reporting the type of ___clang_class, a method with the signature ___clang_expr(void*) is added to that class, so that Clang doesn't complain about a method being defined without a corresponding declaration. - Whenever the expression gets called, "this" gets looked up, type-checked, and then passed in as the first argument. This required the following changes: - The ABIs were changed to support passing of the "this" pointer as part of trivial calls. - ThreadPlanCallFunction and ClangFunction were changed to support passing of an optional "this" pointer. - ClangUserExpression was extended to perform the wrapping described above. - ClangASTSource was changed to revert the changes required by the hack. - ClangExpressionParser, IRForTarget, and ClangExpressionDeclMap were changed to handle different manglings of ___clang_expr flexibly. This meant no longer searching for a function called ___clang_expr, but rather looking for a function whose name *contains* ___clang_expr. - ClangExpressionParser and ClangExpressionDeclMap now remember whether "this" is required, and know how to look it up as necessary. A few inheritance bugs remain, and I'm trying to resolve these. But it is now possible to use "this" as well as refer implicitly to member variables, when in the proper context. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@114384 91177308-0d34-0410-b5e6-96231b3b80d8

Bugfixes to the expression parser. Fixes include: - If you put a semicolon at the end of an expression, this no longer causes the expression parser to error out. This was a two-part fix: first, ClangExpressionDeclMap::Materialize now handles an empty struct (such as when there is no return value); second, ASTResultSynthesizer walks backward from the end of the ASTs until it reaches something that's not a NullStmt. - ClangExpressionVariable now properly byte-swaps when printing itself. - ClangUtilityFunction now cleans up after itself when it's done compiling itself. - Utility functions can now use external functions just like user expressions. - If you end your expression with a statement that does not return a value, the expression now runs correctly anyway. Also, added the beginnings of an Objective-C object validator function, which is neither installed nor used as yet. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@113789 91177308-0d34-0410-b5e6-96231b3b80d8

This is a major refactoring of the expression parser. The goal is to separate the parser's data from the data belonging to the parser's clients. This allows clients to use the parser to obtain (for example) a JIT compiled function or some DWARF code, and then discard the parser state. Previously, parser state was held in ClangExpression and used liberally by ClangFunction, which inherited from ClangExpression. The main effects of this refactoring are: - reducing ClangExpression to an abstract class that declares methods that any client must expose to the expression parser, - moving the code specific to implementing the "expr" command from ClangExpression and CommandObjectExpression into ClangUserExpression, a new class, - moving the common parser interaction code from ClangExpression into ClangExpressionParser, a new class, and - making ClangFunction rely only on ClangExpressionParser and not depend on the internal implementation of ClangExpression. Side effects include: - the compiler interaction code has been factored out of ClangFunction and is now in an AST pass (ASTStructExtractor), - the header file for ClangFunction is now fully documented, - several bugs that only popped up when Clang was deallocated (which never happened, since the lifetime of the compiler was essentially infinite) are now fixed, and - the developer-only "call" command has been disabled. I have tested the expr command and the Objective-C step-into code, which use ClangUserExpression and ClangFunction, respectively, and verified that they work. Please let me know if you encounter bugs or poor documentation. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@112249 91177308-0d34-0410-b5e6-96231b3b80d8
