don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

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.

Added support for breakpoint conditions.  I also had to separate the "run the expression" part of ClangFunction::Execute from the "Gather the expression result" so that in the case of the Breakpoint condition I can move the condition evaluation into the normal thread plan processing.

Also added support for remembering the "last set breakpoint" so that "break modify" will act on the last set breakpoint.

to symbolicate things without the need for a valid process subclass.

Added extra logging for stepping.

Fixed an issue where cached stack frame data could be lost between runs when
the thread plans read a stack frame.

might dump file paths that allows the dumping of full paths or just the
basenames. Switched the stack frame dumping code to use just the basenames for
the files instead of the full path.

Modified the StackID class to no rely on needing the start PC for the current
function/symbol since we can use the SymbolContextScope to uniquely identify
that, unless there is no symbol context scope. In that case we can rely upon
the current PC value. This saves the StackID from having to calculate the 
start PC when the StackFrame::GetStackID() accessor is called.

Also improved the StackID less than operator to correctly handle inlined stack
frames in the same stack.

llvm-svn: 112867

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

Current executable set to 'test/stl/a.out' (x86_64).

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

Also, update BreakpointLocation::ResolveBreakpointSite to check for invalid
breakpoint ID's using the proper magic constant.

enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.

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

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

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.)

llvm-svn: 106078

BreakpointLocation::GetLoadAddress() does not match the 'StoppointLocation::GetLoadAddress() const' virtual function prototype, and so, does not override the superclass function.
