2016-09-06*** This commit represents a complete reformatting of the LLDB source codeKate Stone1-83/+64
*** to conform to clang-format’s LLVM style. This kind of mass change has *** two obvious implications: Firstly, merging this particular commit into a downstream fork may be a huge effort. Alternatively, it may be worth merging all changes up to this commit, performing the same reformatting operation locally, and then discarding the merge for this particular commit. The commands used to accomplish this reformatting were as follows (with current working directory as the root of the repository): find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} + find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ; The version of clang-format used was 3.9.0, and autopep8 was 1.2.4. Secondly, “blame” style tools will generally point to this commit instead of a meaningful prior commit. There are alternatives available that will attempt to look through this change and find the appropriate prior commit. YMMV. llvm-svn: 280751
2016-08-11Decoupled Options from CommandInterpreter.Todd Fiala1-4/+4
Options used to store a reference to the CommandInterpreter instance in the base Options class. This made it impossible to parse options independent of a CommandInterpreter. This change removes the reference from the base class. Instead, it modifies the options-parsing-related methods to take an ExecutionContext pointer, which the options may inspect if they need to do so.

2016-05-12[LLDB] Added support for PHI nodes to IR interpreterMarianne Mailhot-Sarrasin1-0/+1
This allows expressions such as 'i == 1 || i == 2` to be executed using the IR interpreter, instead of relying on JIT code injection (which may not be available on some platforms). Patch by cameron314 Differential Revision: http://reviews.llvm.org/D19124 llvm-svn: 269340
2016-05-09Fixed multiline expressions, and removed some dead code.Sean Callanan1-6/+5
IOHandlerLinesUpdated() does nothing, and IOHandlerIsInputComplete should be implemented but isn't. This means that multiline expressions don't work. This patch fixes that. Test case to follow in the next commit. llvm-svn: 268970
2016-03-29Figure out what the fixed expression is, and print it. Added another target ↵Jim Ingham1-0/+1
setting to quietly apply fixits for those who really trust clang's fixits. Also, moved the retry into ClangUserExpression::Evaluate, where I can make a whole new ClangUserExpression to do the work. Reusing any of the parts of a UserExpression in situ isn't supported at present. <rdar://problem/25351938> llvm-svn: 264793
2016-03-28Expose top-level Clang expressions via the command line and the API.Sean Callanan1-0/+1
Top-level Clang expressions are expressions that act as new translation units, and define their own symbols. They do not have function wrappers like regular expressions do, and declarations are persistent regardless of use of the dollar sign in identifiers. Names defined by these are given priority over all other symbol lookups. This patch adds a new expression option, '-p' or '--top-level,' which controls whether the expression is treated this way. It also adds a flag controlling this to SBExpressionOptions so that this API is usable externally. It also adds a test that validates that this works. (The test requires a fix to the Clang AST importer which I will be committing shortly.) <rdar://problem/22864976> llvm-svn: 264662
2016-03-25Use Clang's FixItHints to correct expressions with "trivial" mistakes (e.g. ↵Jim Ingham1-1/+2
"." for "->".) This feature is controlled by an expression command option, a target property and the SBExpressionOptions setting. FixIt's are only applied to UserExpressions, not UtilityFunctions, those you have to get right when you make them. This is just a first stage. At present the fixits are applied silently. The next step is to tell the user about the applied fixit. <rdar://problem/25351938> llvm-svn: 264379
2015-10-20Added support to the expression command for dropping into the REPL at will.Sean Callanan1-0/+2
"expr -r" does this. It also returns to a REPL if the LLDB command interpreter is neseted inside it, for example in cases where a REPL command resulted in a breakpoint being hit or a crash. llvm-svn: 250780

2015-07-25Specify a language to use when parsing expressions.Dawn Perchik1-0/+1
This patch adds the option -l/--language to the expression command, for use when setting the language options or choosing an alternate FE. If not specified, the target.language setting is used.

2014-01-27Merging the iohandler branch back into main. Greg Clayton1-8/+20
The many many benefits include: 1 - Input/Output/Error streams are now handled as real streams not a push style input 2 - auto completion in python embedded interpreter 3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use 4 - it is now possible to use curses to drive LLDB (please try the "gui" command) We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases. llvm-svn: 200263
2013-11-04Added a "--debug" option to the "expression" command. Greg Clayton1-0/+1
Cleaned up ClangUserExpression::Evaluate() to have only one variant that takes a "const EvaluateExpressionOptions& options" instead of taking many arguments. The "--debug" option is designed to allow you to debug your expression by stopping at the first instruction (it enables --ignore-breakpoints=true and --unwind-on-error=false) and allowing you to step through your JIT code. It needs to be more integrated with the thread plan, so I am checking this in so Jim Ingham can make it happen. llvm-svn: 194009

DumpValueObject() 2.0 This checkin restores pre-Xcode5 functionality to the "po" (expr -O) command: - expr now has a new --description-verbosity (-v) argument, which takes either compact or full as a value (-v is the same as -vfull) When the full mode is on, "po" will show the extended output with type name, persistent variable name and value, as in (lldb) expr -O -v -- foo (id) $0 = 0x000000010010baf0 { 1 = 2; 2 = 3; } When -v is omitted, or -vcompact is passed, the Xcode5-style output will be shown, as in (lldb) expr -O -- foo { 1 = 2; 2 = 3; } - for a non-ObjectiveC object, LLDB will still try to retrieve a summary and/or value to display (lldb) po 5 5 -v also works in this mode (lldb) expr -O -vfull -- 5 (int) $4 = 5 On top of that, this is a major refactoring of the ValueObject printing code. The functionality is now factored into a ValueObjectPrinter class for easier maintenance in the future DumpValueObject() was turned into an instance method ValueObject::Dump() which simply calls through to the printer code, Dump_Impl has been removed Test case to follow llvm-svn: 191694
2013-01-15Separated the "expr --unwind-on-error" behavior into two parts, actual ↵Jim Ingham1-0/+1
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> llvm-svn: 172503
2013-01-09<rdar://problem/12028723>Enrico Granata1-2/+2
Adding useful formatting options to the expression (expr) command. As a side effect of this change, the -d option now supports the same three-values enumeration that frame variables uses (run, don't run, none) instead of a boolean like it did previously These options do not apply to print, p or po because these are aliased to not take any options. In order to use them, use expression or expr. llvm-svn: 171993
2012-10-16Add the ability to set timeout & "run all threads" options both from the ↵Jim Ingham1-0/+2

2012-06-08Make raw & parsed commands subclasses of CommandObject rather than having ↵Jim Ingham1-13/+4
the raw version implement an Execute which was never going to get run and another ExecuteRawCommandString. Took the knowledge of how to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs. Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for the overall command and moved them into the .cpp file. Made the CommandObject flags work for raw as well as parsed commands. Made "expr" use the flags so that it requires you to be paused to run "expr". llvm-svn: 158235
2012-01-27There is no need to hold onto an ExecutionContext as a member variable. Greg Clayton1-1/+0
ExecutionContext objects have shared pointers to Target, Process, Thread and Frame objects and they can end up being held onto for too long. llvm-svn: 149133
2011-10-25Updated all commands that use a "--format" / "-f" options to use the newGreg Clayton1-16/+18
OptionGroupFormat. Updated OptionGroupFormat to be able to also use the "--size" and "--count" options. Commands that use a OptionGroupFormat instance can choose which of the options they want by initializing OptionGroupFormat accordingly. Clients can either get only the "--format", "--format" + "--size", or "--format" + "--size" + "--count". This is in preparation for upcoming chnages where there are alternate ways (GDB format specification) to set a format. llvm-svn: 142911
2011-06-13More prompt-timing cleanups: Make multi-line expressionsCaroline Tice1-2/+2
use the asynchronous stream mechanism rather than writing directly to the Debugger's output & error streams. llvm-svn: 132930
2011-04-16Add support for "dynamic values" for C++ classes. This currently only works ↵Jim Ingham1-0/+1
for "frame var" and for the expressions that are simple enough to get passed to the "frame var" underpinnings. The parser code will have to be changed to also query for the dynamic types & offsets as it is looking up variables. The behavior of "frame var" is controlled in two ways. You can pass "-d {true/false} to the frame var command to get the dynamic or static value of the variables you are printing. There's also a general setting: target.prefer-dynamic-value (boolean) = 'true' which is consulted if you call "frame var" without supplying a value for the -d option. llvm-svn: 129623
2011-04-13Added two new classes for command options:Greg Clayton1-2/+2
lldb_private::OptionGroup lldb_private::OptionGroupOptions OptionGroup lets you define a class that encapsulates settings that you want to reuse in multiple commands. It contains only the option definitions and the ability to set the option values, but it doesn't directly interface with the lldb_private::Options class that is the front end to all of the CommandObject option parsing. For that the OptionGroupOptions class can be used. It aggregates one or more OptionGroup objects and directs the option setting to the appropriate OptionGroup class. For an example of this, take a look at the CommandObjectFile and how it uses its "m_option_group" object shown below to be able to set values in both the FileOptionGroup and PlatformOptionGroup classes. The members used in CommandObjectFile are: OptionGroupOptions m_option_group; FileOptionGroup m_file_options; PlatformOptionGroup m_platform_options; Then in the constructor for CommandObjectFile you can combine the option settings. The code below shows a simplified version of the constructor: CommandObjectFile::CommandObjectFile(CommandInterpreter &interpreter) : CommandObject (...), m_option_group (interpreter), m_file_options (), m_platform_options(true) { m_option_group.Append (&m_file_options); m_option_group.Append (&m_platform_options); m_option_group.Finalize(); } We append the m_file_options and then the m_platform_options and then tell the option group the finalize the results. This allows the m_option_group to become the organizer of our prefs and after option parsing we end up with valid preference settings in both the m_file_options and m_platform_options objects. This also allows any other commands to use the FileOptionGroup and PlatformOptionGroup classes to implement options for their commands. Renamed: virtual void Options::ResetOptionValues(); to: virtual void Options::OptionParsingStarting(); And implemented a new callback named: virtual Error Options::OptionParsingFinished(); This allows Options subclasses to verify that the options all go together after all of the options have been specified and gives the chance for the command object to return an error. It also gives a chance to take all of the option values and produce or initialize objects after all options have completed parsing. Modfied: virtual Error SetOptionValue (int option_idx, const char *option_arg) = 0; to be: virtual Error SetOptionValue (uint32_t option_idx, const char *option_arg) = 0; (option_idx is now unsigned). llvm-svn: 129415
2011-04-07Modified the ArchSpec to take an optional "Platform *" when setting the triple.Greg Clayton1-1/+1
This allows you to have a platform selected, then specify a triple using "i386" and have the remaining triple items (vendor, os, and environment) set automatically. Many interpreter commands take the "--arch" option to specify an architecture triple, so now the command options needed to be able to get to the current platform, so the Options class now take a reference to the interpreter on construction. Modified the build LLVM building in the Xcode project to use the new Xcode project level user definitions: LLVM_BUILD_DIR - a path to the llvm build directory LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb LLVM_CONFIGURATION - the configuration that lldb is built for (Release, Release+Asserts, Debug, Debug+Asserts). I also changed the LLVM build to not check if "lldb/llvm" is a symlink and then assume it is a real llvm build directory versus the unzipped llvm.zip package, so now you can actually have a "lldb/llvm" directory in your lldb sources. llvm-svn: 129112
2011-03-24Fixed the LLDB build so that we can have private types, private enums andGreg Clayton1-2/+2
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. llvm-svn: 128239
2010-11-05Added the equivalent of gdb's "unwind-on-signal" to the expression command, ↵Jim Ingham1-0/+1

available. llvm-svn: 115115
2010-09-18Fixed the way set/show variables were being accessed to being natively Greg Clayton1-5/+3
accessed by the objects that own the settings. The previous approach wasn't very usable and made for a lot of unnecessary code just to access variables that were already owned by the objects. While I fixed those things, I saw that CommandObject objects should really have a reference to their command interpreter so they can access the terminal with if they want to output usaage. Fixed up all CommandObjects to take an interpreter and cleaned up the API to not need the interpreter to be passed in. Fixed the disassemble command to output the usage if no options are passed down and arguments are passed (all disassebmle variants take options, there are no "args only"). llvm-svn: 114252
2010-09-07Small help text fixes, to make it more consistent and accurate.Caroline Tice1-1/+1
Temporarily remove -l option from 'expr' command (at Sean's request). llvm-svn: 113298
2010-08-13Modified CommandObjectExpression::EvaluateExpression() so that it takes anJohnny Chen1-3/+4
additional (ComandReturnObject *) result parameter (default to NULL) and does the right thing in setting the result status. Also removed used variable ast_context. llvm-svn: 110992
2010-08-06Removed the -i option from the expr command, andSean Callanan1-1/+0
made IR-based expression evaluation the default. Also added a new class to hold persistent variables. The class is empty as yet while I write up a design document for what it will do. Also the place where it is currently created (by the Expression command) is certainly wrong. llvm-svn: 110415
2010-06-23Added the temporary -i option to expr, whichSean Callanan1-0/+1

2010-06-23Very large changes that were needed in order to allow multiple connectionsGreg Clayton1-7/+5
to the debugger from GUI windows. Previously there was one global debugger instance that could be accessed that had its own command interpreter and current state (current target/process/thread/frame). When a GUI debugger was attached, if it opened more than one window that each had a console window, there were issues where the last one to setup the global debugger object won and got control of the debugger. To avoid this we now create instances of the lldb_private::Debugger that each has its own state: - target list for targets the debugger instance owns - current process/thread/frame - its own command interpreter - its own input, output and error file handles to avoid conflicts - its own input reader stack So now clients should call: SBDebugger::Initialize(); // (static function) SBDebugger debugger (SBDebugger::Create()); // Use which ever file handles you wish debugger.SetErrorFileHandle (stderr, false); debugger.SetOutputFileHandle (stdout, false); debugger.SetInputFileHandle (stdin, true); // main loop SBDebugger::Terminate(); // (static function) SBDebugger::Initialize() and SBDebugger::Terminate() are ref counted to ensure nothing gets destroyed too early when multiple clients might be attached. Cleaned up the command interpreter and the CommandObject and all subclasses to take more appropriate arguments. llvm-svn: 106615
