Pavel Labath 0fa8396165 Revert "Android.rules: build x86 tests with -mstackrealign"
Starting with android ndk r15, clang much more tests are affected by the
-mstackrealign bugl (now nearly all functions are affected, and not just
the ones requiring 16-byte alignment). Due to their numbers, Xfailing
all of them is not a viable option, so we will just have to declare this
configuration unsupported, and wait until ndk ships a clang version that
has this bug fixed.

Kuba Mracek c40ca13519 [lldb] Add a testcase for MainThreadCheckerRuntime plugin

Pavel Labath 217a763bb2 Android.rules: build x86 tests with -mstackrealign
All android builds systems have switched to -mstackrealign for building
x86 binaries, so follow their cue with our mini build system.

This presently breaks just one test (TestReturnValue), and this is due
to a compiler bug, which has already been fixed in clang, but it hasn't
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
anymore.

Pavel Labath 7f1c12118f Introduce new command: thread backtrace unique
This patch introduces a new thread backtrace command "unique".
The command is based off of "thread backtrace all" but will instead
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.
I needed this behavior recently when debugging a core with 700+ threads.

Pavel Labath 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.

Pavel Labath b5c2a2d959 Disable a test in TestReturnValue on arm64 linux
as described in pr33042, we cannot reliably retrieve the return value on

surgically as possible and disabled it only on targets I know to be

best-effort basis.

Pavel Labath 3559f20f17 ABISysV_arm64: compute return value for large vectors correctly
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).

Pavel Labath 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.

Zachary Turner d0410b6f34 Delete TestLLVM.py
This was added to workaround a limitation in LLVM's implementation
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
on that being set so we would also look in the password database.

Adding the ability to look in the password database to LLVM was
a straightforward patch that was submitted in r298513, so since
that is done this test is no longer needed.

Pavel Labath 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).

Howard Hellyer 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.

Correct 0 byte core files uploaded by arc.

2016-11-24 09:54:09 +00:00
Howard Hellyer 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”.

Dimitar Vlahovski 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.

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.

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.

Summary:
One of the tests was flaky, because similarly to
https://reviews.llvm.org/D18697 (rL265391) - if there is a process running
which is with the same PID as in the core file, the minidump
core file debugging will fail, because we get some information from the
running process.
The fix is routing the ProcessInfo requests through the Process class
and overriding it in ProcessMinidump to return correct data.

Dimitar Vlahovski 7b18dd4f77 Minidump plugin: Adding ProcessMinidump, ThreadMinidump and register the plugin in SystemInitializerFull
Summary:
This plugin resembles the already existing Windows-only Minidump plugin.
The WinMinidumpPlugin uses the Windows API for parsing Minidumps
while this plugin is cross-platform because it includes a Minidump
parser (which is already commited)

It is able to produce a backtrace, to read the general puprose regiters,
inspect local variables, show image list, do memory reads, etc.

For now the only arches that this supports are x86_32 and x86_64.
This is because I have only written register contexts for those.
Others will come in next CLs.

I copied the WinMinidump tests and adapted them a little bit for them to
work with the new plugin (and they pass)
I will add more tests, aiming for better code coverage.

There is still functionality to be added, see TODOs in code.

This reverts commit r284795, as it breaks watchpoint handling on arm (and
presumable all architectures that report watchpoint hits without executing the
tripping instruction).

There seems to be something fundamentally wrong with this patch: it uses
process_sp->AddPreResumeAction to re-enable the watchpoint, but the whole point
of the step-over-watchpoint logic (which AFAIK is the only user of this class) is
to disable the watchpoint *after* we resume to do the single step.

I have no idea how to fix this except by reverting the offending patch.

Dimitar Vlahovski 8cabfb764d Adding a new Minidump post-mortem debugging plugin
Summary:
This plugin resembles the already existing Windows-only Minidump plugin.
The WinMinidumpPlugin uses the Windows API for parsing Minidumps
while this plugin is cross-platform because it includes a Minidump
parser (which is already commited)

It is able to produce a backtrace, to read the general puprose regiters,
inspect local variables, show image list, do memory reads, etc.

For now the only arch that this supports is x86 64 bit
This is because I have only written a register context for that arch.
Others will come in next CLs.

I copied the WinMinidump tests and adapted them a little bit for them to
work with the new plugin (and they pass)
I will add more tests, aiming for better code coverage.

There is still functionality to be added, see TODOs in code.

The lldbutil.run_break_set_by_file_and_line has already checked that the number of 
locations was 1, so don't check it again.  And certainly don't check it again by 
grubbing in break list output.

Also, we know the Thread's IsStopped state is wrong, and have a test for that, so 
don't keep testing it in other files where that isn't the primary thing we're testing.

Todd Fiala 9666ba7526 add stop column highlighting support
This change introduces optional marking of the column within a source
line where a thread is stopped.  This marking will show up when the
source code for a thread stop is displayed, when the debug info
knows the column information, and if the optional column marking is
enabled.

There are two separate methods for handling the marking of the stop
column:

* via ANSI terminal codes, which are added inline to the source line
  display.  The default ANSI mark-up is to underline the column.

* via a pure text-based caret that is added in the appropriate column
  in a newly-inserted blank line underneath the source line in
  question.

There are some new options that control how this all works.

* settings set stop-show-column

  This takes one of 4 values:

  * ansi-or-caret: use the ANSI terminal code mechanism if LLDB
    is running with color enabled; if not, use the caret-based,
    pure text method (see the "caret" mode below).

  * ansi: only use the ANSI terminal code mechanism to highlight
    the stop line.  If LLDB is running with color disabled, no
    stop column marking will occur.

  * caret: only use the pure text caret method, which introduces
    a newly-inserted line underneath the current line, where
    the only character in the new line is a caret that highlights
    the stop column in question.

  * none: no stop column marking will be attempted.

* settings set stop-show-column-ansi-prefix

  This is a text format that indicates the ANSI formatting
  code to insert into the stream immediately preceding the
  column where the stop column character will be marked up.
  It defaults to ${ansi.underline}; however, it can contain
  any valid LLDB format codes, e.g.

      ${ansi.fg.red}${ansi.bold}${ansi.underline}

* settings set stop-show-column-ansi-suffix

  This is the text format that specifies the ANSI terminal
  codes to end the markup that was started with the prefix
  described above.  It defaults to: ${ansi.normal}.  This
  should be sufficient for the common cases.

Significant leg-work was done by Adrian Prantl.  (Thanks, Adrian!)

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

This reverts commit rL280668 because the register tests fail on i386

I investigated a little bit what causes the failure - there are missing
registers when running 'register read -a'.
This is the output I got at the bottom:
"""

Also looking at the packets exchanged between the client and server:
"""

"""

The bndcfgu and bndstatus registers don't have the 'Memory Protections
Extension' set. I looked at the code and it seems that that is set
correctly.

So I'm not sure what's the problem or where does it come from.

Also there is a second failure related to something like this in the
tests:
"""

For some reason the registerSet.GetName() returns None.

Sean Callanan 4740a734bb Added the "frame diagnose" command and use its output to make crash info better.
When a process stops due to a crash, we get the crashing instruction and the
crashing memory location (if there is one).  From the user's perspective it is
often unclear what the reason for the crash is in a symbolic sense.

To address this, I have added new fuctionality to StackFrame to parse the 
disassembly and reconstruct the sequence of dereferneces and offsets that were
applied to a known variable (or fuction retrn value) to obtain the invalid
pointer.

This makes use of enhancements in the disassembler, as well as new information
provided by the DWARF expression infrastructure, and is exposed through a
"frame diagnose" command.  It is also used to provide symbolic information, when
available, in the event of a crash.

The algorithm is very rudimentary, and it needs a bunch of work, including
  - better parsing for assembly, preferably with help from LLVM
  - support for non-Apple platforms
  - cleanup of the algorithm core, preferably to make it all work in terms of
    Operands instead of register/offset pairs
  - improvement of the GetExpressioPath() logic to make prettier expression
    paths, and
  - better handling of vtables.
I welcome all suggestios, improvements, and testcases.

Summary:

The Intel(R) Memory Protection Extensions (Intel(R) MPX) associates pointers
to bounds, against which the software can check memory references to
prevent out of bound memory access.

This patch allows accessing the MPX registers:
  * bnd0-3: 128-bit registers to hold the bound values,
  * bndcfgu, bndstatus: 64-bit configuration registers,

This patch also adds read/write tests for the MPX registers in the register
command tests and adds a new subdirectory for MPX specific tests.

Pavel Labath 21159ee681 Make Scalar::GetValue more consistent
Summary:
It seems the original intention of the function was printing signed values in decimal format, and
unsigned values in hex (without the leading "0x"). However, signed and unsigned long were
exchanged, which lead to amusing test failures in TestMemoryFind.py.

Instead of just switching the two, I think we should just print everything in decimal here, as
the current behaviour is very confusing (especially when one does not request printing of types).
Nothing seems to depend on this behaviour except and we already have a way for the user to
request the format he wants when printing values for most commands (which presumably does not go
through this function).

I also add a unit tests for the function in question.

Tamas Berghammer 3785393def Skip 2 android test what is broken because of debuggerd
debuggerd is a crash reporting system on android what installs some
signal handler for SEGV to print a backtrace in the log. Its behavior
breaks tests where the test tries to continue after a SEGV so we skip
them as this behavior isn't required on android anyway.

Zachary Turner f343968f5d Delete Host/windows/win32.h
It's always hard to remember when to include this file, and
when you do include it it's hard to remember what preprocessor
check it needs to be behind, and then you further have to remember
whether it's windows.h or win32.h which you need to include.

This patch changes the name to PosixApi.h, which is more appropriately
named, and makes it independent of any preprocessor setting.

There's still the issue of people not knowing when to include this,
because there's not a well-defined set of things it exposes other
than "whatever is missing on Windows", but at least this should
make it less painful to fix when problems arise.

This patch depends on LLVM revision r278170.

Dimitar Vlahovski 023dd64f25 Add/fix support for i386 elf core files
Summary:
There were places in the code, assuming(hardcoding) offsets
and types that were only valid for the x86_64 elf core file format.

The NT_PRSTATUS and NT_PRPSINFO structures are with the 64 bit layout.
I have reused them and parse i386 files manually, and fill them in the
same struct.

Also added some error handling during parsing that checks if the
available bytes in the buffer are enough to fill the structures.

The i386 core file test case now passes.

For reference on the structures layout, I generally used the
source of binutils (bfd, readelf)

Todd Fiala 6118ce1221 Breakup TestConcurrentEvents.py into separate test subdirs per test method
This change breaks up the monolithic TestConcurrentEvents.py into a
separate subdir per test method. This allows them to run concurrently,
reduces the chance of a timeout occurring during normal operation, and
allows us to home in on any test methods that may be locking up.

This is step one in the process of squashing timeouts in these test
methods.

The reason for breaking each test method into its own file is to make it
very clear to us if there are a subset of the tests that do in fact lock
up frequently. This will limit how much hunting we need to do to
recreate it.

The reason for putting each file in a separate subdirectory is so that
our concurrent test runner can run multiple test files at the same time.
The unit of serialization in the LLDB test suite is the test directory,
so moving them into separate directories enables the test runner to do
more at the same time.

This change introduces usage of VPATH from gnu make. I use that to
facilitate keeping a single copy of the main.cpp in the parent
concurrent_events directory. Initially I had tried specifying the source
file as ../main.cpp, but our current makefile rules get confused by that
and then also build the output into the parent directory, which defeats
the ability to run each of the test methods concurrently. In the event
that not all systems support VPATH, I can do a bit of surgery on the
Makefile rules and attempt to make it smarter with regards to relative
paths to source files used in the build.

Ravitheja Addepally b3b972a5a8 Fix for PrintStackTraces
Summary:
The issue arises due to the wrong unwinder used for the first
stack frame, where the default unwinder returns erroneous frame
whereas the fallback would have given the correct frame had it
been used.
The following fix consists of two parts ->
 1) The first part changes the unwinding strategy, earlier the
    default unwinder was used to get 2 more stack frames and if it
    failed a fallback unwinder was used. Now we try to obtain as many
    frames (max 10) as we can get from default unwinder and also
    fallback unwinder and use the one that gives more number of frames.
    
 2) Normally unwindplans are assosciated with functions and the
    row to be used is obtained from the offset (obtained from the low_pc
    of the function symbol). Sometimes it may occur that the unwindplan
    is assosciated to the complete Elf section in which case the offset
    calculation would be wrong as the debugger uses the same offset originally
    obtained from the function symbol. Hence this offset is recalculated.

Todd Fiala 3d2c1e6a7c fix invalid assumption about the executable module in Target::Install()
Target::Install() was assuming the module at index 0 was the executable.
This is often true, but not guaranteed to be the case.  The
TestInferiorChanged.py test highlighted this when run against iOS.
After the binary is replaced in the middle of the test, it becomes the
last module in the list.  The rest of the Target::Install() logic then
clobbers the executable file by using whatever happens to be the first
module in the target module list.

This change also marks the TestInferiorChanged.py test as a no-debug-info
test.

Sean Callanan 968bb72f58 Make lldbinline.py regenerate the Makefile each time it builds.
If a lldbinline test's source file changed language, then the Makefile wasn't
updated.  This was a problem if the Makefile was checked into the repository.

Now lldbinline.py always regenerates the Makefile and asserts if the
newly-generated version is not the same as the one already there.  This ensures
that the repository will never be out of date without a buildbot failing.

Pavel Labath ebc7135f8e Fix race in TestExitDuringStep and unify pseudo_barrier handling
Summary:
TestExitDuringStep was very rarely hanging on the buildbots. I can't be sure, but I believe this
was because of the fact that it declared its pseudo_barrier variable as "volatile int", which is
not sufficient to guarantee corectness (also, all other tests used atomic variables for this, and
they were passing reliably AFAIK). Besides switching to an atomic variable in this test as well,
I have also took this opportunity to unify all the copies of the pseudo_barrier code to a single
place to reduce the chance of this happening again.

Pavel Labath 5c17454cd6 Make destructor breakpoint location test more resilient
Summary:
The original breakpoint location test was failing for linux, because the compilers here tend to
merge the full-object and subobject destructors even at -O0 (as a result, we are getting only 2
breakpoint locations, and not 4 as the test expected. The fixup in r266164 substantially weakened
the test, as it now did not check whether both kinds of destructors were being found.

Because of these contraints, I have altered the logic of the test. It sets the
breakpoint by name, and then independently verifies that the breakpoint is set on the correct
demangled symbol name (which is not very meaningful since both kinds of destructors demangle to
the same name) *and* the correct symbol address (which is obtained by looking up the mangled
symbol name).

actually check for big-endian target byte order, but contain Python errors
in the corresponding code paths.

These test cases:
  functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py
  functionalities/data-formatter/data-formatter-smart-array/TestDataFormatterSmartArray.py
  functionalities/data-formatter/synthcapping/TestSyntheticCapping.py
  lang/cpp/frame-var-anon-unions/TestFrameVariableAnonymousUnions.py
  python_api/sbdata/TestSBData.py  (first change)
could be fixed to check for big-endian target byte order and update the
expected result strings accordingly.  For the two synthetic tests, I've
also updated the source to make sure the fake_a value is always nonzero
on both big- and little-endian platforms.

These test case:
  python_api/sbdata/TestSBData.py  (second change)
  functionalities/memory/cache/TestMemoryCache.py
simply accessed memory with the wrong size, which wasn't noticed on LE
but fails on BE.

Ulrich Weigand 377e4213e1 Fixes for platforms that default to unsigned char
This fixes several test case failure on s390x caused by the fact that
on this platform, the default "char" type is unsigned.

- In ClangASTContext::GetBuiltinTypeForEncodingAndBitSize we should return
  an explicit *signed* char type for encoding eEncodingSint and bit size 8,
  instead of the default platform char type (which may be unsigned).
  This fix matches existing code in ClangASTContext::GetIntTypeFromBitSize,
  and fixes the TestClangASTContext.TestBuiltinTypeForEncodingAndBitSize
  unit test case.

- The test/expression_command/char/TestExprsChar.py test case is known to
  fail on platforms defaulting to unsigned char (pr23069), and just needs
  to be xfailed on s390x like on arm.

- The test/functionalities/watchpoint/watchpoint_on_vectors/main.c test
  case defines a vector of "char" and implicitly assumes to be signed.
  Use an explicit "signed char" instead.

Ulrich Weigand bb00d0b6b2 Support Linux on SystemZ as platform
This patch adds support for Linux on SystemZ:
- A new ArchSpec value of eCore_s390x_generic
- A new directory Plugins/ABI/SysV-s390x providing an ABI implementation
- Register context support
- Native Linux support including watchpoint support
- ELF core file support
- Misc. support throughout the code base (e.g. breakpoint opcodes)
- Test case updates to support the platform

This should provide complete support for debugging the SystemZ platform.
Not yet supported are optional features like transaction support (zEC12)
or SIMD vector support (z13).

There is no instruction emulation, since our ABI requires that all code
provide correct DWARF CFI at all PC locations in .eh_frame to support
unwinding (i.e. -fasynchronous-unwind-tables is on by default).

The implementation follows existing platforms in a mostly straightforward
manner.  A couple of things that are different:

- We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers,
  since some registers (access register) reside at offsets in the user area
  that are multiples of 4, but the PTRACE_PEEKUSER interface only allows
  accessing aligned 8-byte blocks in the user area.  Instead, we use a s390
  specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that
  allows accessing a whole block of the user area in one go, so in effect
  allowing to treat parts of the user area as register sets.

- SystemZ hardware does not provide any means to implement read watchpoints,
  only write watchpoints.  In fact, we can only support a *single* write
  watchpoint (but this can span a range of arbitrary size).  In LLDB this
  means we support only a single watchpoint.  I've set all test cases that
  require read watchpoints (or multiple watchpoints) to expected failure
  on the platform.  [ Note that there were two test cases that install
  a read/write watchpoint even though they nowhere rely on the "read"
  property.  I've changed those to simply use plain write watchpoints. ]

Greg Clayton 08f5674bfe Fixed being able to set breakpoints on destructors when we don't fully specify the demangled name. So all of the following now work:
(lldb) b ~Foo
(lldb) b Foo::~Foo
(lldb) b Bar::Foo::~Foo

Improved out C++ breakpoint locations tests as well to cover this issue.

Jim Ingham ff7ac6a7b9 Breakpoint conditions were making result variables, which they should not do.
The result variables aren't useful, and if you have a breakpoint on a
common function you can generate a lot of these.  So I changed the
code that checks the condition to set ResultVariableIsInternal in the
EvaluateExpressionOptions that we pass to the execution.
Unfortunately, the check for this variable was done in the wrong place
(the static UserExpression::Evaluate) which is not how breakpoint
conditions execute expressions (UserExpression::Execute).  So I moved
the check to UserExpression::Execute (which Evaluate also calls) and made the
overridden method DoExecute.
