the resulting function from the .o file DWARF didn't make it into the final
executable. I recently changed the way FindFunctions() worked in the DWARF
with debug map case that caused regressions in our test suite for dead
stripped functions. The previous changes allowed us to leverage the powerful
searching added to the DWARF parser (search by full name, basename, selector,
or method name), without having to chop up the symbol names from the symbol
table and do any special parsing of the names to extract the basename,
selector or method. Previously we would look through the symbol table for
matches first, then try and find the .o file with DWARF for that symbol and
only search those .o files. Now we let the DWARF for the .o file search using
the new search styles, and filter out any functions that didn't make it.

expression. It is now possible to do things like this:
(lldb) expr int $i = 5; $i + 1
$0 = (int) 6
(lldb) expr $i + 3
$1 = (int) 8
(lldb) expr $1 + $0
$2 = (int) 14
As a bonus, this allowed us to move printing of
expression results into the ClangPersistentVariable
class. This code needs a bit of refactoring -- in
particular, ClangExpressionDeclMap has eaten one too
many bacteria and needs to undergo mitosis -- but the
infrastructure appears to be holding up nicely.

expression parser. It is now possible to type:
(lldb) expr int $i = 5; $i + 1
(int) 6
(lldb) expr $i + 2
(int) 7
The skeleton for automatic result variables is
also implemented. The changes affect:
- the process, which now contains a
ClangPersistentVariables object that holds
persistent variables associated with it
- the expression parser, which now uses
the persistent variables during variable
lookup
- TaggedASTType, where I loaded some commonly
used tags into a header so that they are
interchangeable between different clients of
the class

stop event is pulled from the event queue. Then made the StopInfoBreakpoint's PerformAction do the
breakpoint command.
Also fixed the StopInfoBreakpoint's GetDescription so it gets the breakpoint location info, not the breakpoint
site info.
llvm-svn: 110637
Arrange that this then gets properly set on attach, or when a "file" is set.
Add a completer for "process attach -n".
Caveats: there isn't currently a way to handle multiple processes with the same name. That

llvm-svn: 110624
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

TestSTL.test_step_into_stl(), which is known to always fail currently, with
@unittest2.expectedFailure.

This will allow debugger plug-ins to make any instance of "lldb_private::StopInfo"
that can completely describe any stop reason. It also provides a framework for
doing intelligent things with the stop info at important times in the lifetime
of the inferior.
Examples include the signal stop info in StopInfoUnixSignal. It will check with
the process to see that the current action is for the signal. These actions
include wether to stop for the signal, wether the notify that the signal was
hit, and wether to pass the signal along to the inferior process. The
StopInfoUnixSignal class overrides the "ShouldStop()" method of StopInfo and
this allows the stop info to determine if it should stop at the signal or
continue the process.
StopInfo subclasses must override the following functions:
virtual lldb::StopReason
GetStopReason () const = 0;
virtual const char *
GetDescription () = 0;
StopInfo subclasses can override the following functions:
// If the subclass returns "false", the inferior will resume. The default
// version of this function returns "true" which means the default stop
// info will stop the process. The breakpoint subclass will check if
// the breakpoint wants us to stop by calling any installed callback on
// the breakpoint, and also checking if the breakpoint is for the current
// thread. Signals will check if they should stop based off of the
// UnixSignal settings in the process.
virtual bool
ShouldStop (Event *event_ptr);
// Sublasses can state if they want to notify the debugger when "ShouldStop"
// returns false. This would be handy for breakpoints where you want to
// log information and continue and is also used by the signal stop info
// to notify that a signal was received (after it checks with the process
// signal settings).
virtual bool
ShouldNotify (Event *event_ptr)
{
return false;
}
// Allow subclasses to do something intelligent right before we resume.
// The signal class will figure out if the signal should be propagated
// to the inferior process and pass that along to the debugger plug-ins.
virtual void
WillResume (lldb::StateType resume_state)
{
// By default, don't do anything
}
The support the Mach exceptions was moved into the lldb/source/Plugins/Process/Utility

including superclass members. This involved ensuring
that access control was ignored, and ensuring that
the operands of BitCasts were properly scanned for
variables that needed importing.
Also laid the groundwork for declaring objects of
custom types; however, this functionality is disabled
for now because of a potential loop in ASTImporter.
llvm-svn: 110174
involved watching for the objective C built-in types in DWARF and making sure
when we convert the DWARF types into clang types that we use the appropriate
ASTContext types.
Added a way to find and dump types in lldb (something equivalent to gdb's
"ptype" command):
image lookup --type <TYPENAME>
This only works for looking up types by name and won't work with variables.
It also currently dumps out verbose internal information. I will modify it
to dump more appropriate user level info in my next submission.
Hookup up the "FindTypes()" functions in the SymbolFile and SymbolVendor so
we can lookup types by name in one or more images.
Fixed "image lookup --address <ADDRESS>" to be able to correctly show all
symbol context information, but it will only show this extra information when
the new "--verbose" flag is used.
Updated to latest LLVM to get a few needed fixes.

Propagate the status of one-liner execution back appropriately.
llvm-svn: 109899
lldb_private::Language class into the enumerations header so it can be freely
used by other interfaces.
Added correct objective C class support to the DWARF symbol parser. Prior to
this fix we were parsing objective C classes as C++ classes and now that the
expression parser is ready to call functions we need to make sure the objective
C classes have correct AST types.
llvm-svn: 109574
Right now we mock up the function as a variadic

it returns a list of functions as a SymbolContextList.
Rewrote the clients of SymbolContext to use this
SymbolContextList.
Rewrote some of the providers of the data to SymbolContext
to make them respect preferences as to whether the list

ClangExpressionDeclMap and ClangASTSource use this new

class is a templatized class that allows you to have a cleanup function called
on a data value of type T when the value is set or when the object goes
out of scope. It has support for very rudimentary invalid value detection that
can be enabled by using the appropriate constructor.
Anyone with template experience that can see ways of improving this class
please let me know. The example code shows a few typical scenarios in which
I would like to use it. It is currently coded with simple type T values
in mind (integer file descriptors, pointers, etc), but I am sure some
specialization might help out the class for more complex types.
There is a lot of documentation including examples in the CleanUp.h header
file.

ThreadCancel in Host::WillTerminate g_monitor_thread may be blocked on a call
to pthread_cond_wait (for example, line 640). Now, by default, when a
cancellation request is serviced g_monitor_thread will again own the mutex
guarding the condition variable it was waiting on. This causes the call to
SetValue in Host::WillTerminate to hit a deadlock.
The call to SetValue does not appear to be needed, so removing it solves
the issue.

llvm-svn: 109131
I also added new functions to create an Objective C class, ivar and set an objective C superclass. They aren't hooked up in the DWARF parser yet. That is the next step, though I am unsure if I will do this in the DWARF parser or try and do it generically in the existing Record manipulation functions.
llvm-svn: 109130
SectionType for Section objects for DWARF.
Modified the DWARF plug-in to get the DWARF sections by SectionType so we
can safely abstract the LLDB core from section names for the various object

Modified the SectionType definitions for .debug_pubnames and .debug_pubtypes
to use the correct case.
llvm-svn: 109054
defines that are in "llvm/Support/MachO.h". This should allow ObjectFileMachO

Also did some cleanup on the ASTType by renaming it to ClangASTType and

functionality from lldb_private::Type over into ClangASTType.
llvm-svn: 109046
used by the JIT compiled expression, including the
result of the expression.
Also added a new class, ASTType, which encapsulates an

Refactored ClangExpressionDeclMap to use ASTTypes,

types from different AST contexts.
llvm-svn: 108965

llvm-svn: 108289
Makefile patch to explicitly use PROJ_SRC_DIR when required. It fixes
build when obj dir is not source dir.
I also fixed a build warning in ClangResultSynthesizer.cpp.
llvm-svn: 108210
This relies on ThreadPlanStepOut working correctly, which it doesn't currently for Inlined functions, so this feature is only partially useful until we take care of Stepping Out of inlined functions.
Added an option to "thread step-in" to set the avoid regular expression. This is mostly for testing, once the Setting code is redone, we'll move this to a general setting.
llvm-svn: 108036
enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.
llvm-svn: 108009

NDEBUG.
llvm-svn: 107853
Move the "source", "alias", and "unalias" commands to "commands *".
Move "source-file" to "source list".

llvm-svn: 107751
instead of the last history item to provide a command for the "empty" command.

module lldbtest.py and refactored the existing test cases to derive from the

that are in the disassembly comments since most of them are in the same
module (shared library).
Fixed a crasher that could happen when disassembling special section data.
Added an address dump style that shows the symbol context without the module
(used in the disassembly code).
llvm-svn: 107366
Added the ability to read memory from the target's object files when we aren't
running, so disassembling works before you run!
Cleaned up the API to lldb_private::Target::ReadMemory().
Cleaned up the API to the Disassembler to use actual "lldb_private::Address"
objects instead of just an "addr_t". This is nice because the Address objects
when resolved carry along their section and module which can get us the
object file. This allows Target::ReadMemory to be used when we are not
running.
Added a new lldb_private::Address dump style: DumpStyleDetailedSymbolContext
This will show a full breakdown of what an address points to. To see some
sample output, execute a "image lookup --address <addr>".
Fixed SymbolContext::DumpStopContext(...) to not require a live process in
order to be able to print function and symbol offsets.
llvm-svn: 107350
do 'variable list this' command when stopped.
Applied some cleanup on TestArrayTypes.py. In particular, specify the absolute
path to the object file in order not to confuse the debugger.
llvm-svn: 107330
Add functions to look up debugger by id
Add global variable to lldb python module, to hold debugger id
Modify embedded Python interpreter to update the global variable with the
id of its current debugger.
Modify the char ** typemap definition in lldb.swig to accept 'None' (for NULL)
as a valid value.
The point of all this is so that, when you drop into the embedded interpreter
from the command interpreter (or when doing Python-based breakpoint commands),
there is a way for the Python side to find/get the correct debugger
instance ( by checking debugger_unique_id, then calling
SBDebugger::FindDebuggerWithID on it).
llvm-svn: 107287
Add a way for the completers to say whether the completed argument should have a space inserted after is
or not.
Added the file name completer to the "file" command.
llvm-svn: 107247
Also modified dotest.py so that it sets the LLDB_TEST environment variable
so that individual test cases can locate their supporting files correctly.
llvm-svn: 107220
Added the ability to dump any file in the global module cache using any of
the "image dump" commands. This allows us to dump the .o files that are used
with DWARF + .o since they don't belong the the target list for the current
target.
llvm-svn: 107100
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.
llvm-svn: 107075
Tests for lldb are written as python scripts which take advantage of the script
bridging provided by LLDB.framework to interact with lldb core.
A specific naming pattern is followed by the .py script to be recognized as
a module which implements a test scenario, namely, Test*.py.
To specify the directories where "Test*.py" python test scripts are located,
you need to pass in a list of directory names. By default, the current
working directory is searched if nothing is specified on the command line.
An example:
[14:10:20] johnny:/Volumes/data/lldb/svn/trunk/test $ ./dotest.py -v example
test_choice (TestSequenceFunctions.TestSequenceFunctions) ... ok
test_sample (TestSequenceFunctions.TestSequenceFunctions) ... ok

llvm-svn: 106703
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
I'm not sure when multiple threads enter this method but a race-condition
causing a crash in malloc can be reproduced with this little script:

echo "run\nbreak set -n main\nrun\nexit" >> cmd
lldb -s cmd
It may need a few runs before it crashes though.
llvm-svn: 106544
This also fixes a bug where we were trying to copy m_string into itself
via a format string. The pointer was invalidated by m_string.resize and
lldb (sometimes) crashed inside vsnprintf.
llvm-svn: 106416
without having to use RTTI.
Removed the ThreadPlanContinue and replaced with a ShouldAutoContinue query that serves the same purpose. Having to push
another plan to assert that if there's no other indication the target should continue when this plan is popped was flakey
and error prone. This method is more stable, and fixed problems we were having with thread specific breakpoints.
llvm-svn: 106378

Push this through all the breakpoint management code. Allow this to be set when the breakpoint is created.
Fix the Process classes so that a breakpoint hit that is not for a particular thread is not reported as a
breakpoint hit event for that thread.
Added a "breakpoint configure" command to allow you to reset any of the thread

llvm-svn: 106045
Fixed the Disassemble arguments so you can't specify start address or name in multiple ways.
Fixed the command line input so you can specify the filename without "-f" even if you use other options.
llvm-svn: 106020
BreakpointLocation::GetLoadAddress() does not match the 'StoppointLocation::GetLoadAddress() const' virtual function prototype, and so, does not override the superclass function.
llvm-svn: 105927
We need to put this in LLDB since we need to vend this in our API
because our public API uses shared pointers to our private objects.
Removed a deprecated file: include/lldb/Host/Types.h
Added the new SharingPtr.cpp/.h files into source/Utility.
Added a shell script build phase that fixes up all headers in the
LLDB.framework.

type and sub-type, or an ELF e_machine value. Also added a generic CPU type
to the arch spec class so we can have a single arch definition that the LLDB
core code can use. Previously a lot of places in the code were using the
mach-o definitions from a macosx header file.
Switches over to using "llvm/Support/MachO.h" for the llvm::MachO::XXX for the
CPU types and sub types for mach-o ArchSpecs. Added "llvm/Support/ELF.h" so
we can use the "llvm::ELF::XXX" defines for the ELF ArchSpecs.
Got rid of all CPU_TYPE_ and CPU_SUBTYPE_ defines that were previously being
used in LLDB.
llvm-svn: 105806
The top of the header file seems to indicate that this was
