Jim Ingham a73f8ea4e5 Looks like this is how you identify executables in ELF.

Jim Ingham 3ebcf7f09b Make breakpoint commands work again. Added a PerformAction to the stop info - actions are run when the
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.

Added a generic message generator to the lldbtest.py base module.

Jim Ingham 5aee162f97 Change Target & Process so they can really be initialized with an invalid architecture.
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
will have to wait on a way to pass annotations along with the completion strings.

Johnny Chen 0077809bc2 Added some commonly used assert messages to the lldbtest.py module which houses
the TestBase.  Modified TestArrayTypes.py to use the assert messages.  Other
files to follow.

Sean Callanan fc16cc0a0c Removed the -i option from the expr command, and
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: 110400
2010-08-05 23:47:51 +00:00
Johnny Chen 73258830f3 o Added unittest2 which has added the new features in unittest for Python 2.7
backported to Python 2.3+.  Some of the features desired include better
  verbose reporting in unittest2.TextTestRunner and decorator support for
  skipping tests and expected failures.

  http://pypi.python.org/pypi/unittest2

o Modified the existing .py tests to use unittest2 and decorated
  TestSTL.test_step_into_stl(), which is known to always fail currently, with
  @unittest2.expectedFailure.

Johnny Chen a21249597e When running a single test case, lldb.SBDebugger.Terminate() is not being called
because unittest.main() calls sys.exit() before returning.  Fixed by registering
an exit handler for this situation.

Greg Clayton f4b47e1579 Abtracted the old "lldb_private::Thread::StopInfo" into an abtract class.
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
folder and now doesn't polute the lldb_private::Thread class with platform
specific code.

Sean Callanan 5666b674f3 Added support for accessing members of C++ objects,
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: 110093
2010-08-03 01:26:16 +00:00
Greg Clayton b0b9fe610a Added support for objective C built-in types: id, Class, and SEL. This
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.

Sean Callanan 4cf04d209b Set a CodeGenOption in Clang to inhibit insertion
of profiling code into expressions.

member accesses correctly.  (Reading and writing
both work.)

Sean Callanan 5300d37aa7 Added support for rewriting objc_msgSend so we can
call Objective-C methods from expressions.  Also added
some more logging to the function-calling thread plan
so that we can see the registers when a function
finishes.

Also documented things maybe a bit better.

Greg Clayton 3382c2c80d Fixed debugserver to not exit when we are able to spawn the process, yet not
launch it due to not being able to get the task port. A SIGHUP was killing us
and also an error string wasn't properly being passed along. Got rid of a
class error variable that can only lead to multi-threaded crashes.

Johnny Chen 7dc2e4784e We can do better when reporting the status of one-liner script execution.
Change the prototype of ScriptInterpreter::ExecuteOneLine() to return bool
instead of void and take one additional parameter as CommandReturnObject *.

Propagate the status of one-liner execution back appropriately.

Greg Clayton 5fb47cd535 Fixed "void *ClangASTContext::CreatePointerType (void *clang_type);" to return objective C pointers for clang::Type::TypeClass types that are "clang::Type::ObjCObject" and "clang::Type::ObjCInterface" .

Greg Clayton 4b4b5fcebc Fixed expression result printing to have the expression result type be in
parens and to have a space before the value.

Before:
(lldb) expr 3 + 1
int4

(lldb) expr 3 + 1
(int) 4

Greg Clayton 9e40956aea Created lldb::LanguageType by moving an enumeration from the
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
2010-07-28 02:04:09 +00:00
Sean Callanan cc54bd3cef Added and improved logging. This is helping us as we

PIC code.

Johnny Chen 571bfd6a2d Added a test case to test that break on a struct declaration has no effect.
Instead, the first executable statement is set as the breakpoint.

2010-07-27 21:49:20 +00:00
Sean Callanan 7ea3501bd8 Added support for calling functions from expressions.
Right now we mock up the function as a variadic
function when generating the IR for the call; we need
to eventually make the function be the right type if
the type is available.
