Jim Ingham 2976d00adb Change "Current" as in GetCurrentThread, GetCurrentStackFrame, etc, to "Selected" i.e. GetSelectedThread. Selected makes more sense, since these are set by some user action (a selection). I didn't change "CurrentProcess" since this is always controlled by the target, and a given target can only have one process, so it really can't be selected.

Johnny Chen 5fca8ca8cd o Added a test case for array_types which uses the Python APIs from lldb.py,
with the only exception of launching the process from SBTarget which is under
  investigation.

o build-swig-Python.sh should also checks the timestamp of ${swig_input_file}
  for update eligibility.  Also, once an update is in order, there's no need
  to check the remaining header files for timestamps.

o Coaches swig to treat StopReason as an int type, instead of a C++ class.

Greg Clayton 0445d8f498 Cleaned up the inline stack frame code one more time to prepare for inlined
code stepping. Also we now store the stack frames for the current and previous
stops in the thread in std::auto_ptr objects. When we create a thread stack
frame list we pass the previous frame into it so it can re-use the frames
and maintain will allow for variable changes to be detected. I will implement
the stack frame reuse next.

Johnny Chen 61703c96f2 Minor doc string modification.
llvm-svn: 112103
2010-08-25 22:56:10 +00:00
Johnny Chen f3c59231b3 Added logic to TestUniversal.py to exercise the python APIs:
o SBDebugger.GetCurrentTarget()
o SBTarget.GetProcess()
o SBProcess.GetAddressByteSize()

in order to make sure that, indeed, 64-bit, followed by 32-bit processes have
been launched.

Added invoke() method to TestBase to factor in the tracing logic in one place.
This method allows an object to call a method with no arg reflectively.

2010-08-25 22:52:45 +00:00
Johnny Chen 981463d670 Fixed a logic error in the expect() method. If the start string does not match,
there's no point matching further sub strings; the expect() already fails.

Also cleaned up the assert message for VARIABLES_DISPLAYED_CORRECTLY.

Johnny Chen f2b70237e6 Allow command retries in case of process launch failures. This recovery
mechanism seems to work fine on my MacBook Pro in some limited test cases.

The default maxLaunchCount and timeWait variables used in the scheme can be
overridden by the env variables LLDB_MAX_LAUNCH_COUNT and LLDB_TIME_WAIT.

Greg Clayton a45533defa The destructor for StackFrameList doesn't need to be virtual as we aren't
subclassing it anywhere.

Greg Clayton 158483cf62 Thread no longer needs to be a friend in StackFrameList now that StackFrameList
contains the entire stack backtrace.

llvm-svn: 112009
2010-08-25 00:58:59 +00:00
Greg Clayton 12daf946c8 Cleaned up the inline backtrace code even more by moving all stack backtracing
functionality into StackFrameList. This will allow us to copy the previous
stack backtrace from the previous stop into another variable so we can re-use
as much as possible from the previous stack backtrace.

Johnny Chen 536b7d2d26 Removed the @unitest2.expectedFailure decorator. The i386 process launch works
correctly after all.  It was my own configuration error (I was building x86_64
only).

2010-08-24 23:14:47 +00:00
Greg Clayton 288e5afe6b Fixed another issue with the inline stack frames where if the first frame
has inlined functions that all started at the same address, then the inlined
backtrace would not produce correct stack frames.

Also cleaned up and inlined a lot of stuff in lldb_private::Address.

Added a function to StackFrame to detect if the frame is a concrete frame so
we can detect the difference between actual frames and inlined frames.

Johnny Chen 3c884a014c Added a test for launching a universal binary. Launch of i386 architecture
currently fails: rdar://problem/8349784.

Forgot to check in lldbtest.py in the previous commit r111958.

llvm-svn: 111975
2010-08-24 22:07:56 +00:00
Greg Clayton 9da7bd0739 Got a lot of the kinks worked out in the inline support after debugging more
complex inlined examples.

StackFrame classes don't have a "GetPC" anymore, they have "GetFrameCodeAddress()".
This is because inlined frames will have a PC value that is the same as the 
concrete frame that owns the inlined frame, yet the code locations for the
frame can be different. We also need to be able to get the real PC value for
a given frame so that variables evaluate correctly. To get the actual PC
value for a frame you can use:

    addr_t pc = frame->GetRegisterContext()->GetPC();

Some issues with the StackFrame stomping on its own symbol context were 
resolved which were causing the information to change for a frame when the
stack ID was calculated. Also the StackFrame will now correctly store the
symbol context resolve flags for any extra bits of information that were 
looked up (if you ask for a block only and you find one, you will alwasy have
the compile unit and function).

Greg Clayton bba1ba8575 Clear the inline stack frame info when we clean all stack frames.
llvm-svn: 111891
2010-08-24 01:28:00 +00:00
Greg Clayton 1b72fcb7d1 Added support for inlined stack frames being represented as real stack frames
which is now on by default. Frames are gotten from the unwinder as concrete
frames, then if inline frames are to be shown, extra information to track
and reconstruct these frames is cached with each Thread and exanded as needed.

I added an inline height as part of the lldb_private::StackID class, the class
that helps us uniquely identify stack frames. This allows for two frames to
shared the same call frame address, yet differ only in inline height.

Fixed setting breakpoint by address to not require addresses to resolve.

A quick example:

% cat main.cpp

% ./build/Debug/lldb test/stl/a.out 
Current executable set to 'test/stl/a.out' (x86_64).
(lldb) breakpoint set --address 0x0000000100000d31

Each inline frame contains only the variables that they contain and each inlined
stack frame is treated as a single entity.

Johnny Chen 9bc867aaf5 Makefile refactoring for the test suite. Added a make directory under test,

Johnny Chen d0190a6182 Changed the keyword argument for runCmd()/expect() from 'verbose' to 'trace',
which, defaults to False, and if set to True, will trace lldb command execution
and result.

Added "-t" command option to the test driver dotest.py which sets the
LLDB_COMMAND_TRACE environment variable to "YES" and as a result always turns on
command tracing regardless of the 'trace' keyword argument to runCmd()/expect().

Greg Clayton 2cf205ff23 Fixed the Xcode project file to not build all architectures

llvm-svn: 111743
2010-08-21 20:12:22 +00:00
Greg Clayton 0b76a2c21f Modified the host process monitor callback function Host::StartMonitoringChildProcess
to spawn a thread for each process that is being monitored. Previously
LLDB would spawn a single thread that would wait for any child process which
isn't ok to do as a shared library (LLDB.framework on Mac OSX, or lldb.so on
linux). The old single thread used to call wait4() with a pid of -1 which 
could cause it to reap child processes that it shouldn't have.

Re-wrote the way Function blocks are handles. Previously I attempted to keep
all blocks in a single memory allocation (in a std::vector). This made the
code somewhat efficient, but hard to work with. I got rid of the old BlockList
class, and went to a straight parent with children relationship. This new 
approach will allow for partial parsing of the blocks within a function.

2010-08-20 01:13:58 +00:00
Sean Callanan d0ef0eff61 First step of refactoring variable handling in the
expression parser.  There shouldn't be four separate
classes encapsulating a variable.

ClangExpressionVariable is now meant to be the
container for all variable information.  It has
several optional components that hold data for
different subsystems.

ClangPersistentVariable has been removed; we now
use ClangExpressionVariable instead.

Johnny Chen 27f212d1e6 Abstracted the running of command through the command interpreter and checking
its return status into lldbtest.TestBase.runCmd(); and runCmd() in combination
with checking the output against matching substrings (including startswith) into
lldbtest.TestBase.expect().

TestUnsignedTypes.py is refactored to use the abstracted APIs.  Other test cases
to be modified later.
