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.

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.

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.

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
test_shuffle (TestSequenceFunctions.TestSequenceFunctions) ... ok
----------------------------------------------------------------------
Ran 3 tests in 0.000s
OK

- Rationalized EvaluateExpression to remove a lot
of nesting; also added comments to make it easy
to find what's happening where
- Made ExecuteRawCommandString subcontract out to
EvaluateExpression
- Minor logging improvements

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.

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 file $(which lldb) > cmd
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.

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
than picking bits out of the breakpoint options. Added BreakpointOptions::GetDescription to do this job. Some more mucking
around to keep the breakpoint listing from getting too verbose.
llvm-svn: 106262
other script files around, so they can be run from outside Xcode. Also,
check the current OS, and only try to use the framework structure stuff on
Darwin systems.

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
specific options (or the ignore count.)
llvm-svn: 106078
generated by a script. I don't know if we're still regenerating
it or not; will have to check with Greg about how he's handling this
now. Should update it for the final DWARF3 and soon-to-be-released
DWARF4 constants while I'm at it..
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.

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.
llvm-svn: 105895
Change the Release -rpath LDFLAG to look for LLDB.framework in the
same directory as the lldb binary itself. For the BuildAndIntegration
target, continue to use the ../../ etc path to match how we install
the binaries inside Apple.
Patch from Dimiter "malkia" Stanev. I still need to look at the
suggested changing of ONLY_ACTIVE_ARCH settings.

ickiness, and is cleaner to boot.
I'm fairly confident that I converted the comparator over properly,
and what testing I could figure out how to run seemed to pass, but it
would be great if someone in the know could check behind me.

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
intended to be over at include/lldb/Core but we should be in line
with the .cpp file's location so it's include/lldb/Utility for now.

Google C++ coding guidelines where includes are done as:
1 - the header file for the current source file
2 - C includes
3 - C++ includes
4 - external project includes
5 - current project includes
