the process status is indeed 'stopped' before invoking 'frame variable -t val'
command to inspect the frame variable. When I run the test suite, it sometimes
emits an output like:
runCmd: frame variable -t val
runCmd failed!
error: you must be stopped in a valid stack frame to view frame variables.
The expect() statement inserted is to make sure that the process is stopped and
we have a valid frame.

Increase the delta between successive test cases, enabled with the '-w' option to
the test driver, from 0.5 to 1.0 second, to arrive at a cleaner state before the
next test case.

RegisterContext* - normally this is retrieved from the ExecutionContext's
StackFrame but when we need to evaluate an expression while creating
the stack frame list this can be a little tricky.
Add DW_OP_deref_size, needed for the _sigtramp FDE expression.
Add support for processing DWARF expressions in RegisterContextLLDB.
Update callers to DWARFExpression::Evaluate.

perform recursive type lookups, because these are not
required for full type fidelity. We also make the
SelectorTable last for the full lifetime of the Clang
compiler; this was the source of many bugs.

that the result of an expression should be coerced to
a specific type. Also made breakpoint conditions pass
in the bool type for this type.
The expression parser ignores this indication for now.

changing it to use it. There was an extra parameter added to the static
accessor global user settings controllers that wasn't needed. A bool was being
used as a parameter to the accessor just so it could be used to clean up
the global user settings controller which is now fixed by splitting up the
initialization into the "static void Class::Initialize()", access into the
"static UserSettingsControllerSP & Class::GetSettingsController()", and
cleanup into "static void Class::Terminate()".
Also added initialize and terminate calls to the logging code to avoid issues
when LLDB is shutting down. There were cases after the logging was switched
over to use shared pointers where we could crash if the global destructor
chain was being run and it causes the log to be destroyed and any any logging
occurred.

by being able to get the data count and data. Each thread stop reason
has one or more data words that can help describe the stop. To do this
I added:
size_t
SBThread::GetStopReasonDataCount();
uint64_t
SBThread::GetStopReasonDataAtIndex(uint32_t idx);

to the DoHalt down in ProcessGDBRemote. I also moved the functionality that
was in ProcessGDBRemote::DoHalt up into Process::Halt so not every class has
to implement a tricky halt/resume on the internal state thread. The
functionality is the same as it was before with two changes:
- when we eat the event we now just reuse the event we consume when the private
state thread is paused and set the interrupted bool on the event if needed
- we also properly update the Process::m_public_state with the state of the
event we consume.
Prior to this, if you issued a "process halt" it would eat the event, not
update the process state, and then produce a new event with the interrupted
bit set and send it. Anyone listening to the event would get the stopped event
with a process that whose state was set to "running".
Fixed debugserver to not have to be spawned with the architecture of the
inferior process. This worked fine for launching processes, but when attaching
to processes by name or pid without a file in lldb, it would fail.
Now debugserver can support multiple architectures for a native debug session
on the current host. This currently means i386 and x86_64 are supported in
the same binary and a x86_64 debugserver can attach to a i386 executable.
This change involved a lot of changes to make sure we dynamically detect the
correct registers for the inferior process.

with the Interrupted bit set. Process::HandlePrivateEvent ignores Interrupted events.
DoHalt is changed to ensure that the stop even is processed, and an event with
the Interrupted event is posted. Finally ClangFunction is rationalized to use this
facility so the that Halt is handled more deterministically.

output from clang and llvm-gcc compiled program; both generate the correct debug
info with respect to the typedef scoped inside a namespace.
Add a TestBase.getCompiler(self) method which returns the compiler in effect the
test suite is now running with. Subclasses (like TestNamespace) can use it to
distinguish among different compilers.

This is not to be used during normal test suite run, but to be used to stress test
specific test sequences repeatedly.
Example:
./dotest.py -# 3 -v breakpoint_conditions
will repeat the test suite 3 times for tests under the breakpoint_conditions directory.

ReadThread stuff into the main Process class (out of the Process Plugins).
This has the (intended) side effect of disabling the command line tool
from reading input/commands while the process is running (the input is
directed to the running process rather than to the command interpreter).

we're using the stack pointer to define the CFA again. Makes unwinds
while sitting at the 'ret' instruction work, assuming we have accurate
function address bounds.
