Johnny Chen cb9b857959 Added TestArrayTypes.py for test/array_types directory.
Also modified dotest.py so that it sets the LLDB_TEST environment variable
so that individual test cases can locate their supporting files correctly.

Johnny Chen 4657be6e63 For the time being, let's bracket the test runner within the
lldb.SBDebugger.Initialize()/Terminate() pair.

Change TestHelp.py to use synchronous debugging, which is easier to work with.

Greg Clayton d0c8a0f031 A little code cleanup to not create an script bridging object just to feed
the private object back to another internal function.

Greg Clayton 8d38ac4536 Fixed debug map in executable + DWARF in .o debugging on Mac OS X.
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.

Greg Clayton 0c5cd90d63 Added function name types to allow us to set breakpoints by name more
intelligently. The four name types we currently have are:

eFunctionNameTypeFull       = (1 << 1), // The function name.
                                        // For C this is the same as just the name of the function
                                        // For C++ this is the demangled version of the mangled name.
                                        // For ObjC this is the full function signature with the + or
                                        // - and the square brackets and the class and selector
eFunctionNameTypeBase       = (1 << 2), // The function name only, no namespaces or arguments and no class 
                                        // methods or selectors will be searched.
eFunctionNameTypeMethod     = (1 << 3), // Find function by method name (C++) with no namespace or arguments
eFunctionNameTypeSelector   = (1 << 4)  // Find function by selector name (ObjC) names


this allows much more flexibility when setting breakoints:

(lldb) breakpoint set --name main --basename
(lldb) breakpoint set --name main --fullname
(lldb) breakpoint set --name main --method
(lldb) breakpoint set --name main --selector

The default:

(lldb) breakpoint set --name main

will inspect the name "main" and look for any parens, or if the name starts
with "-[" or "+[" and if any are found then a full name search will happen.
Else a basename search will be the default.

Fixed some command option structures so not all options are required when they
shouldn't be.

Cleaned up the breakpoint output summary.

Made the "image lookup --address <addr>" output much more verbose so it shows
all the important symbol context results. Added a GetDescription method to 
many of the SymbolContext objects for the more verbose output.

Johnny Chen a765c28db3 A simple testing framework for lldb using python's unit testing framework.
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

Sean Callanan 562a5a3904 Improved printing of LLVM IR. We now print
complete instructions rather than simply their
opcodes.

Sean Callanan 16ad5faeeb Extensive code cleanup of the expression command.
- 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

llvm-svn: 106703
2010-06-24 00:16:27 +00:00
Sean Callanan 1d389c4b02 Added the temporary -i option to expr, which
switches the expression parsing over to use the
LLVM IR as opposed to Clang ASTs.  Right now,
that functionality only logs.

Greg Clayton 6611103cfe Very large changes that were needed in order to allow multiple connections
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.

Sean Callanan f06ba8d89c Updated the expression parser to use proper logging when
looking for external variables.  Also cleaned up the log
messages coming from the DWARF interpreter.

llvm-svn: 106613

2010-06-22 21:28:05 +00:00
Benjamin Kramer b328d72d77 Turns out __cxa_demangle returns the size of the buffer instead of the size of
the demangled name. Fall back to strlen.

llvm-svn: 106579
2010-06-22 21:27:55 +00:00
Jim Ingham 05407f6b25 Make an explicit GetThreadSpecNoCreate accessor so you don't have to get the const-ness right to ensure you are not making a copy of the owning breakpoint's ThreadSpec in a breakpoint location. Also change the name from NoCopy to NoCreate since that's clearer.
llvm-svn: 106578
2010-06-22 21:12:54 +00:00
Benjamin Kramer eb9165c08f Reduce code duplication.
This also moves strlen out of the mutex scope.

llvm-svn: 106545
2010-06-22 15:28:34 +00:00
Benjamin Kramer 53a61dc531 Ensure GetDemangledName's thread safety by making the demangle buffer thread specific.
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.

Benjamin Kramer 466b31e900 Move a bunch of trivial methods into the header. These compile down to 1-2
instructions so it's really profitable to inline them.

2010-06-21 14:39:40 +00:00
Benjamin Kramer ae39fc196b Return false from FileSpec::GetPath early instead of making the return value
dependent on the last byte of the buffer, which could be unitialized.

Benjamin Kramer e1ce369628 Don't snprintf directly into a std::string, it's undefined behavior per C++03.
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.

Jim Ingham b01e742af7 Two changes in this checkin. Added a ThreadPlanKind so that I can do some reasoning based on the kind of thread plan
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
2010-06-19 04:45:32 +00:00
Jim Ingham b2a38a7286 Remember whether a queue or thread name were passed into "breakpoint modify" so we can recognize an empty argument as unsetting the option.

Jim Ingham 62b02c61c9 Adding setting thread specific breakpoints by name, ID, index & queue name to the SB interfaces.
llvm-svn: 106268
2010-06-18 01:47:08 +00:00
Jim Ingham 4b9bea87e6 Move the "status" command to "process status" since that's where it belongs. Also make it print "running" if invoked
when the current process is running.

llvm-svn: 106265
2010-06-18 01:23:09 +00:00
Jim Ingham 0136309f5a Change the Breakpoint & BreakpointLocation GetDescription methods so they call the BreakpointOptions::GetDescription rather
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
2010-06-18 01:00:58 +00:00
Jim Ingham ae1c4cf568 Change "breakpoint configure" to "breakpoint modify" so it doesn't collide with "breakpoint command"
Change "breakpoint enable/disable" so changing a breakpoint's state doesn't also overwrite the location states.

Caroline Tice d6ac38485b Parameterize the shell scripts for creating and copying the python and

check the current OS, and only try to use the framework structure stuff on

Jim Ingham 1b54c88cc4 Add a "thread specification" class that specifies thread specific breakpoints by name, index, queue or TID.
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.)
