- no setting auto completion
- very manual and error prone way of getting/setting variables
- tons of code duplication
- useless instance names for processes, threads
Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing".

'add-dsym' (aka 'target symbols add') should display error messages when dsym file is not found
or the dsym uuid does not match any existing modules. Add TestAddDsymCommand.py test file.

when you want to find the caller's saved pc, you look up the return address
register and use that. On arm, for instance, this would be the contents of
the link register (lr).
If the eh_frame CIE defines an RA, record that fact in the UnwindPlan.
When we're finding a saved register, if it's the pc, lok for the location
of the return address register instead.

return 0x0 as the read value instead of uninitialized
stack data so we get consistent behavior from the
emulator.

Fixed an issue that could cause references the shared data for an object file to stay around longer than intended and could cause memory bloat when debugging multiple times.

require an AddressClass, which is useless at this
point since it already knows the distinction between
32-bit Thumb opcodes and 32-bit ARM opcodes.

keep a shared pointer to their disassembler. This
is important for the LLVM-C disassembler because
it needs to lock its parent in order to disassemble
itself.
This means that every interface that returned a
Disassembler* needs to return a DisassemblerSP, so
that the instructions and any external owners share
the same reference count on the object. I changed
all clients to use this shared pointer, which also
plugged a few leaks.

Added new API to lldb::SBTypeMember for bitfields:
bool SBTypeMember::IsBitfield();
uint32_t SBTypeMember::GetBitfieldSizeInBits();
Also added new properties for easy access. Now SBTypeMember objects in python have a "fields" property for all type fields, "bases" for all direct bases, "vbases" for all virtual base classes and "members" for a combo of all three organized by bit offset. They all return a python list() of SBTypeMember objects. Usage:
(lldb) script
>>> t = lldb.target.FindFirstType("my_type")
>>> for field in t.fields:
... print field
>>> for vbase in t.vbases:
... print vbase
>>> for base in t.bases:
... print base
>>> for member in t.members:
... print member
Also added new "is_bitfield" property to the SBTypeMember objects that will return the result of SBTypeMember::IsBitfield(), and "bitfield_bit_size" which will return the result of SBTypeMember::GetBitfieldSizeInBits();
I also fixed "SBTypeMember::GetOffsetInBytes()" to return the correct byte offset.

Convert from calling Halt in the lldb Driver.cpp's input reader's sigint handler to sending this AsyncInterrupt so it can be handled in the
event loop.
If you are attaching and get an async interrupt, abort the attach attempt.
Also remember to destroy the process if get interrupted while attaching.
Getting this to work also required handing the eBroadcastBitInterrupt in a few more places in Process WaitForEvent & friends.

calling functions. This is necessary on Mac OS X, since bad things can happen if you set
the registers of a thread that's sitting in a kernel trap.

Remove assertions and turn what used the be the assertion into a logged error with instructions on what to attach to a radar so we can track down why this is happening.

the state of the unwind instructions once the prologue has finished. If it hits an
early return epilogue in the middle of the function, re-instate the prologue after that
epilogue has completed so that we can still unwind for cases where the flow of control
goes past that early-return. <rdar://problem/11775059>
Move the UnwindPlan operator== definition into the .cpp file, expand the definition a bit.
Add some casts to a SBCommandInterpreter::HandleCompletion() log statement so it builds without
warning on 64- and 32-bit systems.

a shared pointer to ease some memory management issues with a patch
I'm working on.
The main complication with using SPs for these objects is that most
methods that build up an UnwindPlan will construct a Row to a given
instruction point in a function, then add additional regsaves in
the next instruction point to that row and push it again. A little
care is needed to not mutate the previous instruction point's Row
once these are switched to being held behing shared pointers.

a bit -- we're creating the UnwindPlan here, we can set the register set to
whatever is convenient for us, no need to handle different register sets.
A handful of small comment fixes I noticed while reading through the code.

Fixed an issue where GDB servers that don't support the thread suffix could get registers states incorrectly due to an incorrect assumption that the current register thread (set using the "Hg%x" packet) will always be cached between runs. Now we clear the cached register thred when the process is resumed.
