This doesn't attempt to move every decorator. The reason for
this is that it requires touching every single test file to import
decorators.py. I would like to do this in a followup patch, but
in the interest of keeping the patches as bite-sized as possible,
I've only attempted to move the underlying common decorators first.
A few tests call these directly, so those tests are updated as part
of this patch.

reason to None when we stop due to a trace, then noticed that
we were on a breakpoint that was not valid for the current thread.
That should actually have set it back to trace.

My eventual goal is to move all of the test decorators to their
own module such as `decorators.py`. But some of the decorators
use existing functions in `lldbtest.py` and conceptually the
functions are probably more appropriately placed in lldbplatformutil.
Moreover, lldbtest.py is a huge file with a ton of random utility
functions scattered around, so this patch also workds toward the
goal of reducing the footprint of this one module to a more
reasonable size.
So this patch moves some of them over to lldbplatformutil with the
eventual goal of moving decorators over to their own module.

This decorator was used in only one test, and it's behaviour was quite complicated. It skipped
if:
- test was remote
- platform was *not* android
I am not aware of anyone running tests with this configuration (and even then, I am not aware of
a reason why the test should not pass), but if TestLoadUnload starts breaking for you after this
commit, please disable the test with
@expectedFailureAll(remote=True, oslist=[YOUR_PLATFORM])

Previously we were returning a tuple of (bool, skip_reason) from
the tuple function. This makes for some awkward code, especially
since a value of True for the first argument implies that the
second argument is None, and a value of False implies that the
second argument is not None. So it was basically redundant, and
with this patch we simply return the skip reason or None directly.

After recent changes, test_thread_state_is_stopped has become equivalent to test_step_in, as the
function exit_during_step_base was not using the "test_thread_state" parameter. As test was
XFAILed on all platforms anyway, and we have other tests for the bug which it (used to) test, I
am simply removing the function.

Summary:
r259344 introduced a bug, where we fail to perform a single step, when the instruction we are
stepping onto contains a breakpoint which is not valid for this thread. This fixes the problem
and add a test case.

Summary:
- The patch solves Bug 23478 and Bug 19311. Resolving
Bug 23478 also resolves Bug 23039.
Correct ThreadStopInfo is set for Linux and FreeBSD
platforms.
- Summary:
When a trace event is reported, we need to check
whether the trace event lands at a breakpoint site.
If it lands at a breakpoint site then set the thread's
StopInfo with the reason 'breakpoint'. Else, set the reason
to be 'Trace'.

Previously the logic of skipIf and expectedFailure were 99%
the same, but they took different sets of arguments since they
were maintained separately, and had slightly differences in
their behavior. This makes everything consistent, there is now
only one real implementation, and the previous ones are changed
to use the single master implementation.

Get the load address for the address given by symbol and function.

This is another example of a test that was looking for the thread
at index 0 instead of requesting the thread that was stopped at
the created breakpoint. This assumption isn't true on Windows 10.
llvm-svn: 258764
In Python 3, whitespace inconsistences are errors. This synthetic
provider had mixed tabs and spaces, as well as inconsistent
indentation widths. This led to the file not being imported,
and naturally the test failing. No functional change here, just
whitespace.

The Windows 10 loader spawns threads at startup, so
tests which count threads or assume that a given user
thread will be at a specific index are incorrect in
this case. The fix here is to use the standard mechanisms
for getting the stopped thread (which is all we are
really interested in anyway) and correlating them with
the breakpoints that were set, and doing checks against
those things.
This fixes about 6 tests on Windows 10.
llvm-svn: 258586
Starting with Windows 10, the Windows loader is itself multi-threaded,
meaning that the loader spins up a few threads to do process
initialization before it executes main. Windows delivers these
notifications asynchronously and they can come out of order, so
we can't be sure that the first thread we get a notification about
is actually the zero'th thread.
This patch fixes this by requesting the thread stopped at the
breakpoint that was specified, rather than getting thread 0 and
verifying that it is stopped at a breakpoint.

Summary:
The issue arises because LLDB is not
able to read the vdso library correctly.
The fix adds memory allocation callbacks
to allocate sufficient memory in case the
requested offsets don't fit in the memory
buffer allocated for the ELF.

TestHelloWorld seems to be passing now as far as I can tell. TestExitDuringStep is still hanging.

TestConcurrentEvents was marked with a XFAIL decorator at class level, which actually does not
work, and causes the class to be silently skipped everywhere. It seems that making it work at
class level is quite a difficult task, so I will just move it to the individual test methods. I
will follow this up with a commit which makes the decorator blow up in case someone tries to
apply it to a class in the future.

There were a number of problems preventing this from working:
1. The SWIG typemaps for converting Python lists to and from C++
arrays were not updated for Python 3. So they were doing things
like PyString_Check instead of using the PythonString from
PythonDataObjects.
2. ProcessLauncherWindows was ignoring the environment completely.
So any test that involved launching an inferior with any kind
of environment variable would have failed.
3. The test itself was using process.GetSTDOUT(), which isn't
implemented on Windows. So this was changed to save the
value of the environment variable in a local variable and
have the debugger look at the value of the variable.

The system can create threads for a system threadpool, so there is
no guarantee that the thread that is stopped is thread 1. So use
a more robust check.
llvm-svn: 257513
Summary:
The testcase TestNoreturnUnwind.py was failing
because the unwind from the vdso library was not
successful for clang compiler while it was passing
for gcc. It was passing for gcc since the unwind plan
used was the assembly plan and the ebp register was
set by the main function in case of gcc and was not
used by the functions in the call flow to the vdso, whereas
clang did not emit assembly prologue for main and so
the assembly unwind was failing. Normally in case of
failure of assembly unwind, lldb switches to EH CFI frame
based unwinding, but this was not happening for
the first frame. This patch tries to fix this behaviour by
falling to EH CFI frame based unwinding in case of assembly
unwind failure even for the first frame.
The test is still marked as XFAIL since it relys on the fix
of another bug.
