the reason being the test was issuing 'disassemble' command to disassemble the current
frame function when stopped.  The 'disassemble' command worked previously but it was a
result of bad option specification.

Fix the disassemble command so that it will require 'disassemble -f' for disassembly of
the current frame function.

Changed the API logging a bit to always show the objects in the OBJECT(POINTER)
format so it will be easy to locate all instances of an object or references
to it when looking at logs.

which holds the name of a file whose contents are
prefixed to each expression.  For example, if the file
~/lldb.prefix.header contains:

typedef unsigned short my_type;

then you can do this:

(lldb) settings set target.expr-prefix '~/lldb.prefix.header'
(lldb) expr sizeof(my_type)
(unsigned long) $0 = 2

When the variable is changed, the corresponding file
is loaded and its contents are fetched into a string
that is stored along with the target.  This string
is then passed to each expression and inserted into
it during parsing, like this:

typedef unsigned short my_type;
                             
void                           
$__lldb_expr(void *$__lldb_arg)          
{                              
    sizeof(my_type);

the breakpoint associated with the (filename, line_number) combo when an arrow is pointing to
a source position using Emacs Grand Unified Debugger library to interact with lldb.

The current implmentation is insufficient in that it only asks the breakpoint whether it is
associated with a breakpoint resolver with FileLine type and whether it matches the (filename, line_number)
combo.  There are other breakpoint resolver types whose breakpoint locations can potentially
match the (filename, line_number) combo.

The BreakpointResolver, BreakpointResolverName, BreakpointResolverAddress, and BreakpointResolverFileLine
classes have extra static classof methods to support LLVM style type inquiry through isa, cast, and dyn_cast.

The Breakpoint class has an API method bool GetMatchingFileLine(...) which is invoked from CommandObjectBreak.cpp
to implement the "breakpoint clear" command.

all of the calls inlined in the header file for better performance.

Fixed the summary for C string types (array of chars (with any combo if
modifiers), and pointers to chars) work in all cases.

Fixed an issue where a forward declaration to a clang type could cause itself
to resolve itself more than once if, during the resolving of the type itself
it caused something to try and resolve itself again. We now remove the clang
type from the forward declaration map in the DWARF parser when we start to 
resolve it and avoid this additional call. This should stop any duplicate
members from appearing and throwing all the alignment of structs, unions and
classes.

After a recent fix to not set the default architecture to "x86_64", the string value for the default arch was coming out as a value that shouldn't be user visible. Now we don't show any value when it isn't set.

      - Try to reduce logging to one line per function call instead of tw
      - Put all arguments & their values into log for calls
      - Add 'this' parameter information to function call logging, making it show the appropriate
        internal pointer (this.obj, this.sp, this.ap...)
      - Clean up some return values
      - Remove logging of constructors that construct empty objects
      - Change '==>' to '=>'  for showing result values...
      - Fix various minor bugs
      - Add some protected 'get' functions to help getting the internal pointers for the 'this' arguments...

Delay getting a full UnwindPlan if it's possible to unwind with
just a fast UnwindPlan.  This keeps us from reading the eh_frame
section unless we hit something built -fomit-frame pointer or we
hit a frame with no symbol (read: no start address) available.

It doesn't look like it is correctly falling back to using the
full UnwindPlan to provide additional registers that the fast
UnwindPlan doesn't supply; e.g. go to the middle of a stack and
ask for r12 and it will show you the value of r12 in frame 0.
That's a bug for tomorrow.

gets to be a problem if you have a unbounded stack walk.

Fix the CFA sanity checks.  Add one to the arch default UnwindPlan run which was giving
one extra stack frame on the main thread.  Fix a couple of logging lines that had their
argument order incorrect.

it logs the function calls, their arguments and the return values.  This is not
complete or polished, but I am committing it now, at the request of someone who
really wants to use it, even though it's not really done.  It currently does not
attempt to log all the functions, just the most important ones.  I will be 
making further adjustments to the API logging code over the next few days/weeks.
(Suggestions for improvements are welcome).


Update the Python build scripts to re-build the swig C++ file whenever

arguments).

Don't set the default architecture to x86_64. Leave it NULL so that it isn't set to anything and so that any single architecture binary will adopt that architecture instead of posting an error stating the binary doesn't contain "x86_64".

Not yet enabled as the default unwinder but there are no known
backtrace problems with the code at this point.

Added 'log enable lldb unwind' to help diagnose backtrace problems;
this output needs a little refining but it's a good first step.

eh_frame information is currently read unconditionally - the code
is structured to allow this to be delayed until it's actually needed.
There is a performance hit when you have to parse the eh_frame
information for any largeish executable/library so it's necessary
to avoid if possible.

It's confusing having both the UnwindPlan::RegisterLocation struct
and the RegisterConextLLDB::RegisterLocation struct, I need to rename
one of them.

The writing of registers isn't done in the RegisterConextLLDB subclass
yet; neither is the running of complex DWARF expressions from eh_frame
(e.g. used for _sigtramp on Mac OS X).
