252d7bdc67 [lldbtests] Handle errors instead of crashing.
If you pass an invalid compiler/debugger path on the cmdline to `dotest.py`  this is what you get.

  Traceback (most recent call last):

f877a0820c Use ipv4 localhost address in lldb-server tests
Since the ipv6 patch, we've experienced occasional flakyness in
lldb-server tests. This was due to the fact that lldb-server was trying
to listen on both v4 and v6 localhost sockets (and consider it a success
if at least one of them succeeded), while the test framework was only
trying to connect to the v4 one.

This change makes sure lldb-server only listens on the v4 socket.

17ffd39ed8 Implement interactive command interruption
The core of this change is the new CommandInterpreter::m_command_state,
which models the state transitions for interactive commands, including
an "interrupted" state transition.

In general, command interruption requires cooperation from the code
executing the command, which needs to poll for interruption requests
through CommandInterpreter::WasInterrupted().

CommandInterpreter::PrintCommandOutput() implements an optionally
interruptible printing of the command output, which for large outputs 
was likely the longest blocking part.
(ex. target modules dump symtab on a complex binary could take 10+ minutes)

8652b249e6 Initial patchset to get the testsuite running against armv7 and arm64 iOS devices.
Normal customer devices won't be able to run these tests, we're hoping to get
a public facing bot set up at some point.  Both devices pass the testsuite without
any errors or failures.

I have seen some instability with the armv7 test runs, I may submit additional patches
to address this.  arm64 looks good.

I'll be watching the bots for the rest of today; if any problems are introduced by
this patch I'll revert it - if anyone sees a problem with their bot that I don't
see, please do the same.  I know it's a rather large patch.

One change I had to make specifically for iOS devices was that debugserver can't 
create files.  There were several tests that launch the inferior process redirecting
its output to a file, then they retrieve the file.  They were not trying to test
file redirection in these tests, so I rewrote those to write their output to a file
directly.

Normal customer devices won't be able to run these devices, we're hoping to get
a public facing bot set up at some point.

There will be some smaller follow-on patches.  The changes to tools/lldb-server are
verbose and I'm not thrilled with having to skip all of these tests manually.
There are a few places where I'm making the assumption that "armv7", "armv7k", "arm64"
means it's an ios device, and I need to review & clean these up with an OS check
as well.  (Android will show up as "arm" and "aarch64" so by pure luck they shouldn't
cause problems, but it's not an assumption I want to rely on).

3887ba8d38 Re-land r313210 - Fix for bug 34532 - A few rough corners related to post-mortem debugging (core/minidump)
The main change is to avoid setting the process state as running when
debugging core/minidumps (details in the bug).  Also included a few small,
related fixes around how the errors propagate in this case.

Fixed the FreeBSD/Windows break: the intention was to keep
Process::WillResume() and Process::DoResume() "in-sync", but this had the
unfortunate consequence of breaking Process sub-classes which don't override
WillResume().

The safer approach is to keep Process::WillResume() untouched and only
override it in the minidump and core implementations.

b842f2ecf0 Make breakpoint names real entities.
When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.  

This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint.  It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names.  There is also full support for
then in the SB API, including a new SBBreakpointName class.

The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well.  This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.

You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.

I also added the ability to make hidden and delete/disable protected
names.  When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.

This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally 
disabled or deleted.

f08f5c9926 Add an auto-continue flag to breakpoints & locations.
You can get a breakpoint to auto-continue by adding "continue"
as a command, but that has the disadvantage that if you hit two
breakpoints simultaneously, the continue will force the process
to continue, and maybe even forstalling the commands on the other.
The auto-continue flag means the breakpoints can negotiate about
whether to stop.

Writing tests, I wanted to supply some commands when I made the
breakpoints, so I also added that ability.

af26b22cd2 Fix a mis-feature with propagation of breakpoint options -> location options.
When an option was set at on a location, I was just copying the whole option set 
to the location, and letting it shadow the breakpoint options.  That was wrong since
it meant changes to unrelated options on the breakpoint would no longer take on this
location.  I added a mask of set options and use that for option propagation.

I also added a "location" property to breakpoints, and added SBBreakpointLocation.{G,S}etCommandLineCommands
since I wanted to use them to write some more test cases.

21a365ba59 NativeProcessLinux: Fix handling of raise(SIGTRAP)
In NativeProcessLinux::MonitorSIGTRAP we were asserting that the si_code
value is one of the codes we know about. However, that list was very
incomplete -- for example, we were not handling SI_TKILL/SI_USER,
generated by raise(SIGTRAP). A cursory examination show there are at
least a dozen codes like these that an app can generate, and more can be
added at any point.

So, instead of trying to play catchup, I change the default behavior to
treat an unknown si_code like an ordinary signal. The only reason we
needed to inspect si_code in the first place is because
watchpoint/breakpoints are notified as SIGTRAP, but we already know
about those, and us starting to use a new debug event is far less likely
than somebody introducing a new non-debug event.

I add a test case to TestRaise to verify we are handling raise(SIGTRAP)
in an application properly.

All android builds systems have switched to -mstackrealign for building

This presently breaks just one test (TestReturnValue), and this is due

made it yet into the official NDK compiler. While I'm touching that
test, I also remove an android-specific XFAIL, which is not relevant

find all threads which share matching call stacks and de-duplicate
their output, listing call stack and all the threads which share it.
This is especially useful for apps which use thread/task pools
sitting around waiting for work and cause excessive duplicate output.

c3c721222d Fix backtrace of noreturn functions situated at the end of a module
Summary:
When a call instruction is the last instruction in a function, the
backtrace PC will point past the end of the function. We already had
special code to handle that, but we did not handle the case where the PC
ends up outside of the bounds of the module containing the function,
which is a situation that occured in TestNoreturnUnwind on android for
some arch/compiler combinations.

I fix this by adding an argument to Address resolution code which states
that we are ok with addresses pointing to the end of a module/section to
resolve to that module/section.

I create a reproducible test case for this situation by hand-crafting an
executable which has a noreturn function at the end of a module.

ddf802a04d [TypeSystem] Handle Clang AttributedTypes
When parsing types originating in modules, it is possible to encounter AttributedTypes 
(such as the type generated for NSString *_Nonnull). Some of LLDB's ClangASTContext 
methods deal with them; others do not. In particular, one function that did not was 
GetTypeInfo, causing TestObjCNewSyntax to fail.

This fixes that, treating AttributedType as essentially transparent and getting the 
information for the modified type.

In addition, however, TestObjCNewSyntax is a monolithic test that verifies a bunch of 
different things, all of which can break independently of one another. I broke it 
apart into smaller tests so that we get more precise failures when something (like 
this) breaks.

45dde23756 Recommit "RunThreadPlan: Fix halting logic in IgnoreBreakpoints = false"
This is a resubmit of r303732, which was reverted due to a regression.

The original patch caused a regression in TestLoadUnload, which has only showed
up when running the remote test suite. The problem there was that we interrupted
the target just as it has hit the rendezvous breakpoint in the dlopen call. This
meant that the stop reason was set to "breakpoint" even though the event would
not have been broadcast if we had not stopped the process. I fix this by
checking StopInfo->ShouldNotify() before stopping.

I also add a new test for the handling of conditional breakpoints in
expressions, which I noticed to be broken (pr33164)

0dc2ad1b13 RunThreadPlan: Fix halting logic in IgnoreBreakpoints = false
Summary:
The function had logic to handle the case when the expression terminated
while we were trying to halt the process, but it failed to take into
account the possibility that the expression stopped because it hit a
breakpoint. This was caused by the fact that the handling of the stopped
events was duplicated for the "halting" and regular cases (the regular
case handled this situation correctly). I've tried to merge these two
cases into one to make sure they stay in sync.

I should call out that the two cases were checking whether the thread
plan has completed in slightly different ways. I am not sure what is the
difference between them, but I think the check should be the same in
both cases, whatever it is, so I just took the one from the regular
case, as that is probably more tested.

For the test, I modified TestUnwindExpression to run the expression with
a smaller timeout (this is how I found this bug originally). With a 1ms
one thread timeout, the test failed consistently without this patch.

09e91ac6ab [DWARF parser] Produce correct template parameter packs
Templates can end in parameter packs, like this

template <class T...> struct MyStruct 
  { /*...*/ };

LLDB does not currently support these parameter packs; 
it does not emit them into the template argument list
at all. This causes problems when you specialize, e.g.:

template <> struct MyStruct<int> 
  { /*...*/ };
template <> struct MyStruct<int, int> : MyStruct<int> 
  { /*...*/ };

LLDB generates two template specializations, each with 
no template arguments, and then when they are imported 
by the ASTImporter into a parser's AST context we get a 
single specialization that inherits from itself, 
causing Clang's record layout mechanism to smash its
stack.

This patch fixes the problem for classes and adds
tests. The tests for functions fail because Clang's
ASTImporter can't import them at the moment, so I've
xfailed that test.

38c2059aec Fix segfault resulting from empty print prompt
Summary:
I have found a way to segfault lldb in 7 keystrokes! Steps to reproduce:
1) Launch lldb
2) Type `print` and hit enter. lldb will now prompt you to type a list of
    expressions, followed by an empty line.
3) Hit enter, indicating the end of your input.
4) Segfault!

After some investigation, I've found the issue in Host/common/Editline.cpp.
Editline::MoveCursor() relies on m_input_lines not being empty when the `to`
argument is CursorPosition::BlockEnd. This scenario, as far as I can tell,
occurs in one specific instance: In Editline::EndOrAddLineCommand() when the
list of lines being processed contains exactly one string (""). Meeting this
condition is fairly simple, I have posted steps to reproduce above.

Summary:
Arm64 Procedure Call Standard specifies than only vectors up to 16 bytes
are stored in v0 (which makes sense, as that's the size of the
register). 32-byte vector types are passed as regular structs via x8
pointer. Treat them as such.

This fixes TestReturnValue for arm64-clang. I also split the test case
into two so I can avoid the if(gcc) line, and annotate each test
instead. (It seems the vector type tests fail with gcc only when
targetting x86 arches).

c02a1c0312 [Expression parser] Return both types and variables
Many times a user wants to access a type when there's a variable of
the same name, or a variable when there's a type of the same name.
Depending on the precise context, currently the expression parser
can fail to resolve one or the other.

This is because ClangExpressionDeclMap has logic to limit the
amount of information it searches, and that logic sometimes cuts
down the search prematurely. This patch removes some of those early
exits.

In that sense, this patch trades performance (early exit is faster)
for correctness.

I've also included two new test cases showing examples of this
behavior – as well as modifying an existing test case that gets it
wrong.

b494578afb [DWARF] Fix lookup in the abstract origins of inlined blocks/functions
LLDB uses clang::DeclContexts for lookups, and variables get put into
the DeclContext for their abstract origin. (The abstract origin is a 
DWARF pointer that indicates the unique definition of inlined code.) 
When the expression parser is looking for variables, it locates the 
DeclContext for the current context. This needs to be done carefully, 
though, e.g.:

__attribute__ ((always_inline)) void f(int a) {
  {
    int b = a * 2;
  }
}

void g() {
  f(3);
}
Here, if we're stopped in the inlined copy of f, we have to find the 
DeclContext corresponding to the definition of f – its abstract 
origin. Clang doesn't allow multiple functions with the same name and 
arguments to exist. It also means that any variables we see must be 
placed in the appropriate DeclContext.

[Bug 1]: When stopped in an inline block, the function 
GetDeclContextDIEContainingDIE for that block doesn't properly
construct a DeclContext for the abstract origin for inlined
subroutines. That means we get duplicated function DeclContexts, but
function arguments only get put in the abstract origin's DeclContext, 
and as a result when we try to look for them in nested contexts they 
aren't found.

[Bug 2]: When stopped in an inline block, the DWARF (for space 
reasons) doesn't explicitly point to the abstract origin for that 
block. This means that the function GetClangDeclContextForDIE returns
a different DeclContext for each place the block is inlined. However, 
any variables defined in the block have abstract origins, so they 
will only get placed in the DeclContext for their abstract origin.

In this fix, I've introduced a test covering both of these issues,
and fixed them.

Bug 1 could be resolved simply by making sure we look up the abstract
origin for inlined functions when looking up their DeclContexts on 
behalf of nested blocks.

For Bug 2, I've implemented an algorithm that makes the DeclContext 
for a block be the containing DeclContext for the closest entity we
would find during lookup that has an abstract origin pointer. That
means that in the following situation:

{ // block 1
  int a;
  { // block 2
    int b;
  }
}
if we looked up the DeclContext for block 2, we'd find the block 
containing the abstract origin of b, and lookup would proceed 
correctly because we'd see b and a. However, in the situation

{ // block 1
  int a;
  { // block 2
  }
}
since there isn't anything to look up in block 2, we can't determine 
its abstract origin (and there is no such pointer in the DWARF for 
blocks). However, we can walk up the parent chain and find a, and its 
abstract origin lives in the abstract origin of block 1. So we simply 
say that the DeclContext for block 2 is the same as the DeclContext 
for block 1, which contains a. Lookups will return the same results.

Thanks to Jim Ingham for review and suggestions.

where it happened to be queried before the general vector formatter. To

01a28ca7f8 Centralize libc++ test skipping logic
Summary:
This aims to replace the different decorators we've had on each libc++
test with a single solution. Each libc++ will be assigned to the
"libc++" category and a single central piece of code will decide whether
we are actually able to run libc++ test in the given configuration by
enabling or disabling the category (while giving the user the
opportunity to override this).

I started this effort because I wanted to get libc++ tests running on
android, and none of the existing decorators worked for this use case:
 - skipIfGcc - incorrect, we can build libc++ executables on android
 with gcc (in fact, after this, we can now do it on linux as well)
 - lldbutil.skip_if_library_missing - this checks whether libc++.so is
 loaded in the proces, which fails in case of a statically linked
 libc++ (this makes copying executables to the remote target easier to
 manage).

To make this work I needed to split out the pseudo_barrier code from the
force-included file, as libc++'s atomic does not play well with gcc on
linux, and this made every test fail, even though we need the code only
in the threading tests.

So far, I am only annotating one of the tests with this category. If
this does not break anything, I'll proceed to update the rest.

of getting the current user's home directory, since it would
only look at the value of $HOME, but we did not want to rely

r298203 make SBPlatform::MakeDirectory less recursive, which breaks the
test suite creation of test directory hierarchy creation on the remote
target. Since the function was never fully recursive, and the name does
not imply recursiveness, I fix the problem by modifying the test runner
to do the recursion manually.

I also make the runner complain more loudly when it fails to create the
directory -- previously it just printed the error to stdout and caused
most of the tests to hang, which is not very helpful in diagnosing the
problem.

version (which was probably incorrect anyway, as it assumes the current
process instead of the inferior.

I also add an llgs test to that verifies thread names are read

bf37a037d0 BreakpointResolverFileLine: Restrict move-to-nearest-code from moving across function boundaries
Summary:
This fixes the case where a user tries to set a breakpoint on a source
line outside of any function (e.g. because that code is #ifdefed out, or
the compiler did not emit code for the function, etc.) and we would
silently move the breakpoint to the next function.

Now we check whether the line range of the resolved symbol context
function matches the original line number. We reject any breakpoint
locations that appear to move the breakpoint into a new function. This
filtering only happens if we have full debug info available (e.g. in
case of -gline-tables-only compilation, we still set the breakpoint on
the nearest source line).

Summary:
This has been broken at least since the new test result framework was

Removing this makes the gmodules handling code saner, as it already did

My motivation for this is libc++ data formatters support on android -- I
am trying make a central way of determining whether libc++ tests can be
run, and without this, I would have to resort to similar hacks as the
gmodules code.

bc58f9aa7b testsuite/android: build test executables with the android ndk directly
Summary:
This teaches the test makefiles about the Android NDK, so we are able to
run the tests without first going through the make_standalone_toolchain
script. The motivation for this is the ability to run both libc++ and
libstdc++ tests together, which previously was not possible because
make_standalone_toolchain bakes in the STL to use during toolchain
creation time. The support for this is not present yet -- this change
only make sure we don't regress for existing funcionality (gcc w/
libstdc++). Clang and libc++ support will be added later.

I've checked that the mips android targets compile after this change,
but I have no way of checking whether this breaks anything. If you are
reading this and it broke you, let me know.

a window where another thread could get the shared pointer to the
empty (but quickly being-filled-in) object and lead to a crash.

Also two changes from Greg for correctness on the TestMultipleDebuggers
test case.

c29f7ff334 Switch "posix" to the new log channel registration mechanism
Summary:
This also removes magic rename code, which caused the channel to be
called "linux" when built on a linux machine, and "freebsd" when built
on a freebsd one, which seems unnecessary - registering a new channel is
sufficiently simple now that if we wish to log something extremely
os-specific, we can just create a new channel. None of the current
categories seem very specific to one OS or another.

a37bbbd432 NPL: Fix one more bug in the single step workaround
In the case we are stepping over the thread creation instruction, we
will end up calling Thread::SingleStep back-to-back twice (because of
the intermediate PTRACE_EVENT_CLONE stop). This will cause the cpu mask
to be set inappropriately (because the old SingleStepCheck object will
be destroyed after we create the new one), and the single-step will
fail.

Before the refactor the code was still incorrect in this case, but in a
different way (the thread was left with the incorrect mask after the
stepping was complete), so this was not easy to spot.

This fixes TestCreateDuringInstructionStep on the affected devices.

d875aae9c0 Fix TestNameLookup for GCC
Summary:
GCC emits also symbols for the __PRETTY_FUNCTION__ virtual variable,
which we accidentaly pick up when looking for functions for with
"unique_function_name" in the name. This makes the target.FindFunctions
call fail, as that symbol is not a function.

I also strenghten the test a bit to make sure we actually find all the
functions we are interested in. I've put a check that we find at least 6
functions, but maybe this should be *exactly* 6 ?

misbehaving. This is because this test switches the selected platform and the

9434690ab7 Simplify reading of Linux notes to correctly handle endianess.
Summary:
This patch changes and simplifies the way notes are read from Linux Elf cores.
The current implementation copies the bytes from the notes directly over the lldb structure for 64 bit cores and reads field by field for 32 bit cores. Reading the bytes directly only works if the endianess of the core dump and the platform that lldb are running on matches. The case statements for s390x and x86_64 would would only work on big endian systems and little endian systems respectively. That meant that x86_64 generally worked but s390x didn't unless you were on s390x or another big endian platform.
This patch just reads field by field on all platform and updates the field by field version to allow for those fields which are word size instead of fixed size. It should also slightly simplify adding support for a new Linux platform.

This patch also re-enables the s390x test case in TestLinuxCore.py on all non-s390x platforms as it now passes.

We're seeing some very occasional failures in these tests where the

the main lldb driver program already ignores SIGPIPE, so ignoring it in

b3a3cd1f4e When we interrupt a process, it was possible or the thread names
to not be set by Process::WillPublicStop() so the driver won't get
access to them.  The fix is straightforward, moving the call to
WillPublicStop above the early return for the interrupt case.  (the
interrupt case does an early return because the rest of the function
is concerned with running stop hooks etc and those are not applicable
when we've interrupted the process).

Also added a test case for it.  The test case is a little complicated
because I needed to drive lldb asynchronously to give the program
a chance to get up and running before I interrupt it.  Running to
a breakpoint was not sufficient to catch this bug.

Internal error [IRForTarget]: An Objective-C constant string's string initializer is not an array

error: The expression could not be prepared to run in the target

This is just a side effect of the fact that we don't handle wide string constants when converting these to CFStringCreateWithBytes. That function takes the string's encoding as an argument, so I made it work and added a testcase.

The current implementation of the decorator does not skip if the android target
arch is the same as host arch (as in both cases the platform comes out as linux).
Nonetheless android x86_64 binaries are not compatible with linux ones.

Technically this should be "skip if target is android and host is *not* android",
but currently nobody runs lldb test suite on an android host, so we don't even

1a2ac9bda5 Patch for lldb bug 26322 “core load hangs”
Summary:
This patch changes the way ProcessElfCore.cpp handles signal information.
The patch changes ProcessElfCore.cpp to use the signal from si_signo in SIGINFO notes in preference to the value of cursig in PRSTATUS notes. The value from SIGINFO seems to be more thread specific. The value from PRSTATUS is usually the same for all threads even if only one thread received a signal.
If it cannot find any SIGINFO blocks it reverts to the old behaviour and uses the value from cursig in PRSTATUS. If after that no thread appears to have been stopped it forces the status of the first thread to be SIGSTOP to prevent lldb hanging waiting for any thread from the core file to change state.

The order is:
- If one or more threads have a non-zero si_signo in SIGINFO that will be used.
- If no threads had a SIGINFO block with a non-zero si_signo set all threads signals to the value in cursig in their PRSTATUS notes.
- If no thread has a signal set to a non-zero value set the signal for only the first thread to SIGSTOP.


This resolves two issues. The first was identified in bug 26322, the second became apparent while investigating this problem and looking at the signal values reported for each thread via “thread list”.

Firstly lldb is able to load core dumps generated by gcore where each thread has a SIGINFO note containing a signal number but cursig in the PRSTATUS block for each thread is 0.

Secondly if a SIGINFO note was found the “thread list” command will no longer show the same signal number for all threads. At the moment if a process crashes, for example with SIGILL, all threads will show “stop reason = signal SIGILL”. With this patch only the thread that executed the illegal instruction shows that stop reason. The other threads show “stop reason = signal 0”.

a228c46c2a ELF core: Adding parsing of the floating-point and SSE registers on x86 32/64 bit elf core files
Summary:
The floating-point and SSE registers could be present in the elf-core
file in the note NT_FPREGSET for 64 bit ones, and in the note
NT_PRXFPREG for 32 bit ones.

The entire note is a binary blob matching the layout of the x87 save
area that gets generated by the FXSAVE instruction (see Intel developers
manual for more information).

This CL mainly modifies the RegisterRead function in
RegisterContextPOSIXCore_x86_64 for it to return the correct data both
for GPR and FPR/SSE registers, and return false (meaning "this register
is not available") for other registers.

I added a test to TestElfCore.py that tests reading FPR/SSE registers
both from a 32 and 64 bit elf-core file and I have inluded the source
which I used to generate the core files.

I tried to also add support for the AVX registers, because this info could
also be present in the elf-core file (note NT_X86_XSTATE - that is the result of
the newer XSAVE instruction). Parsing the contents from the file is
easy. The problem is that the ymm registers are split into two halves
and they are in different places in the note. For making this work one
would either make a "hacky" approach, because there won't be
any other way with the current state of the register contexts - they
assume that "this register is of size N and at offset M" and
don't have the notion of discontinuos registers.

c156427ded Don't allow direct access to StreamString's internal buffer.
This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.

Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

On Windows, where we use Python 3 for testing, we have to be more explicit about converting between binary and string representations.  I believe this should still work for Python 2, but I don't have a convenient way to try it out.

bd3d0263f8 One more cleanup to lldb version printing
With this patch LLDB_VERSION_STRING replaces "lldb version x.x.x" if it is set. This allows builds to not display the open source version numbers if the people making the distribution overrides the LLDB_VERSION_STRING.

Since LLDB_VERSION_STRING is always overridden on Darwin, this means the first line of lldb -version on Darwin is:

833e3d109b Display the pointer value in the libstdc++ unique_ptr summary
Summary:
r284830 added a summary provider for unique_ptr in libstdc++, whose value printed
the value of the pointee. This is a bit unintuitive as it becomes unobvious that
the value actually is a pointer, and we lose the way to actually obtain the
pointer value.

Change that to print the pointer value instead. The pointee value can still be
obtained through the synthetic children.

Summary:
This commit disables the windows-only minidump plugin and enables the new
cross-platform plugin for windows minidump files. Test decorators are adjusted to
reflect that: windows minidump tests can now run  on all platforms. The exception
is the tests that create minidump files, as that functionality is not available
yet.  I've checked that this works on windows and linux.

6a9767c7e6 Clean up the stop printing header lines.
I added a "thread-stop-format" to distinguish between the form
that is just the thread info (since the stop printing immediately prints
the frame info) and one with more frame 0 info - which is useful for
"thread list" and the like.

I also added a frame.no-debug boolean to the format entities so you can
print frame information differently between frames with source info and those
without.

This renames the functionalities/postmortem/linux-core to elf-core and puts the
"linux" part into the individual names of the core files. Since the tests for
linux and freebsd core files are going to be very similar, having them close
together means they can reuse most of the plumbing.

0f80cc84f0 Test for YMMRegisters.
Summary:
This patch contains test for reading YMM Registers. The test basically
contains an inferior that loads the ymm registers with a bit pattern
and the python test executes register read to check if the bit pattern
is correctly written in the registers. This test is repeated twice for
each register with a different pattern for better sanity.

We don't have a good story for what happens to watchpoints when you don't

how to fix this for real.

Also added a test to make sure disable->enable works as well.
