Greg Clayton a658fd26c3 Created a std::string in the base StopInfo class for the description and 
cleaned up all base classes that had their own copy. Added a SetDescription
accessor to the StopInfo class.

Greg Clayton 850cc8998c Remove asserts that will crash LLDB. These should be changed to return 
true/false in an extra boolean parameter and not cause the the binary that
us using the LLDB framework to crash.

 2011-06-02 22:23:35 +00:00
Greg Clayton dd0e5a5258 Make sure we don't lose our stop reply packet in the case where the other 
GDB server doesn't support the LLDB specific qThreadStopInfo packet.

 2011-06-02 22:22:38 +00:00
Greg Clayton 8672996e4d Update the handle many of the packets that our current LLDB debugserver

Johnny Chen 8831e18b17 Make 'run-until-faulted.py' script more interesting by modifying the example main.c program 
to seg fault randomly instead of deterministically.

Johnny Chen 755faf7744 Make it clear that the Python script modify-python-lldb.py is responsible for post-processing 
the SWIG-generated lldb.py module by adding comments in the post-processed file in order to
facilitate reading of the code.

Charles Davis 4ce288e3e4 Fix remaining Python issues leftover from my previous patch. 
- The Swig post-processing scripts are now run.
- edit-swig-python-wrapper-file.py has been modified so it can be run
from the Makefile.
- The issue that prompted me to pass -classic to swig is fixed by this,
so -classic isn't passed anymore.

Python shouldn't complain anymore about a missing method 'FindDebuggerByID'
on the SBDebugger object whenever lldb is run.

Greg Clayton 5d2fbfed4d Disable dynamic types being on by default until kinks get worked out when 
they don't update correctly. Currently if a variable is unavailable due to
a register not being available in a higher frame or due to the PC value
not being a valid location list value, "<unknown type>" will get displayed
as the variable type. I am not sure what other things will fail, so I am 
disabling it for now just by letting the default enumeration value default
to it being disabled.

Greg Clayton 18d85eedda Make sure if an enumeration "settings" value has a valid default setting in 
its definition, that the first enumeration doesn't always get used as the
default.

Greg Clayton fc3f027d33 Don't have the debugger default to ignoring EOF. This is only what the driver 
(or anything running in a terminal) wants. Not what a UI (Xcode) would want 
where it creates a debugger per debug window. The current code had an infinite
loop after a debug session ended.
