RegisterContextLLDB holds a reference to the SymbolContext
in the vector of Cursors that UnwindLLDB maintains. Switch
UnwindLLDB to hold a vector of shared pointers of Cursors
so this reference doesn't become invalid.
Correctly falling back from the "fast" UnwindPlan to the
"full" UnwindPlan when additional registers need to be
retrieved.

the end of the list. We had an issue in the MacOSX dynamic loader where if
we had shlibs:
1 - a.out
2 - a.dylib
3 - b.dylib
And then a.dylib got unloaded, we would unload b.dylib due to the assumption
that only shared libraries could come off the end of the list. We now properly
search and find which ones get loaded.
Added a new internal logging category for the "lldb" log channel named "dyld".
This should allow all dynamic loaders to use this as a generic log channel so
we can track shared library loads and unloads in the logs without having to
have each plug-in make up its own logging channel.

set breakpoints at the different locations where
an exception could be thrown, so that exceptions
thrown by expressions are properly caught.

ptrace thread update that was replying to the SIGSTOP was also causing the
process to not really be sigstop'd any more so then the call to ptrace
detach was failing, and when debugserver exited the attached process
was being killed. Now the ptrace thread update does not disturb the sigstop
state of the thread, so the detach works properly.

statement. Now when ClangExpressionDeclMap returns
a variable for a name, it pretty-prints that
variable to the log instead of printing a (fairly
useless) NamedDecl pointer.

Objective-C member accessibility restrictions.
Ultimately Clang should have a flag that ignores
accessibility for Objective-C like it has one
for C++.

than just the entire log channel.
Add checks, where appropriate, to make sure a log channel/category has
not been disabled before attempting to write to it.

2. FoundationDisassembleTestCase.test_simple_disasm_with_dwarf
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.

by type ID (the most common type of type lookup).
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);
}

version); change include statements to use Python.h in the Python framework
on Mac OS X systems; leave it using regular Python.h on other systems.
Note: I think this *ought* to work properly on Linux systems, but I don't have
a system to test it on...

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.
