Muhammad Omair Javaid 9b95835698 [LLDB] Add core definition for armv8l and armv7l
This patch adds core definitions in lldb ArchSpecs for armv8l and armv7l cores.

This was needed because on Linux running on 32-bit Arm v8 we are returned
armv8l in case we are running 32-bit sysroot on 64bit kernel. In case of 32-bit
kernel and 32-bit sysroot running on arm v8 hardware we are returned armv7l.
This is quite common when we run 32 bit arm using docker container.

This is basically the same bug as in r260434.

through dependency DAG of .pcm files because each object file and .pcm
file may depend on an already-visited .pcm file, which may again have
dependencies. Fixed here by carrying a set of already visited

António Afonso 31ea714e9a Add rpath to liblldb so vendors can ship their own python framework (or others)
Summary:
I want to be able to specify which python framework to use for lldb in macos. With python2.7 we could just rely on the MacOS one but python3.7 is not shipped with the OS.
An alternative is to use the one shipped with Xcode but that could be path dependent or maybe the user doesn't have Xcode installed at all.
A definite solution is to just ship a python framework with lldb. To make this possible I added "@loader_path/../../../" to the rpath so it points to the same directory as the LLDB.framework, this way we can just drop any frameworks there.

Adrian Prantl da83e96273 Fix a regression in macOS-style path remapping.
When we switched to the LLVM .debug_line parser, the .dSYM-style path
remapping logic stopped working for relative paths because of how
RemapSourceFile silently fails for relative paths. This patch both
makes the code more readable and fixes this particular bug.

One interesting thing I learned is that Module::RemapSourceFile() is a
macOS-only code path that operates on on the lldb::Module level and is
completely separate from target.source-map, which operates on a
per-Target level.

Jonas Devlieghere c62a9f180c [lldb] Improve assert in GDBRemoteCommunicationReplayServer
While investigating an issue where a different packet was sent during
replay I noticed how annoying it is that the existing assert doesn't
specify what packet is actually different. It's printed to the log, but
enabling logging has the potential to change LLDB's behavior. The same
is true when debugging LLDB while it's replaying the reproducer.

I replaced the assert with a printf of the unexpected packet followed by
a fatal_error wrapped in ifndef NDEBUG. The behavior is the same as the
previous assert, just with more/better context.

For example, in "0x1111111 - 0x22222 +MyApp Pro arm64 <01234>", the
name of the image was recognized as "MyApp Pro arm64" instead of
"MyApp Pro" with a "version" of arm64.

*inside* the optional group.

This both reverts r357277 to rebundle a version of Python's readline module
based on libedit.

However, this patch also provides two improvements over the previous
implementation:

1. use PyMem_RawMalloc instead of PyMem_Malloc, as expected by PyOS_Readline
   (prevents to segfault upon exit of interactive session)
2. patch the readline module upon embedded interpreter loading, instead of
   patching it globally, which should prevent any side effect on other
   modules/packages
3. only activate the patched module if libedit is actually linked in lldb

Pavel Labath 28cf9698ab MemoryRegion: Print "don't know" permission values as such
Summary:
The permissions in a memory region have ternary states (yes, no, don't
know), but the memory region command only prints in binary, treating
"don't know" as "yes", which is particularly confusing as for instance
the unwinder will treat an unknown value as "no".

This patch makes is so that we distinguish all three states when
printing the values, using "?" to indicate the lack of information. It
is implemented via a special argument to the format provider for the
OptionalBool enumeration.

Michał Górny 6eca4f4691 [lldb] [Process/NetBSD] Add register info for missing register sets
Add info for all register sets supported in NetBSD, particularly for all
registers 'expected' by LLDB.  This is necessary in order to fix
python_api/lldbutil/iter/TestRegistersIterator.py test that currently
fails due to missing names of register sets (None).

This copies fpreg descriptions from Linux, and combines Linux' AVX
and MPX registers into a single XState group, to fit NetBSD register
group design.  Technically, we do not support MPX registers
at the moment but gdb-remote insists on passing their errors anyway,
and if we do not include it in any group, they end up in a separate
anonymous group that breaks the test.

While at it, swap the enums for XState and DBRegs to match register set
ordering.

This also adds a few consts to the lldb-x86-register-enums.h to provide
more consistency between user registers and debug registers.

Martin Storsjö 1739c7c10c Reapply [LLDB] [test] Use %clang_cl instead of build.py in a few tests
This allows explicitly specifying the intended target architecture,
for tests that aren't supposed to be executed, and that don't
require MSVC headers or libraries to be available.

(These tests already implicitly assumed to be built for x86; one
didn't specify anything, assuming x86_64, while the other specified
--arch=32, which only picks the 32 bit variant of the default target
architecture).

Join two comment lines in disassembly.cpp, to keep row numbers
checked in the test unchanged.

This fixes running check-lldb on arm linux.

Previously when this was applied (in 95980409e6), it broke
macos buildbots, as they added "-isysroot <path>" to all %clang*
substitutions, and clang-cl didn't support that.

Reapplying it without further changes to this patch, after D69619

Pavel Labath 193a7bfb69 minidump: Create memory regions from the sections of loaded modules
Summary:
Not all minidumps contain information about memory permissions. However,
it is still important to know which regions of memory contain
potentially executable code. This is particularly important for
unwinding on win32, as the default unwind method there relies on
scanning the stack for things which "look like" code pointers.

This patch enables ProcessMinidump to reconstruct the likely permissions
of memory regions using the sections of loaded object files. It only
does this if we don't have a better source (memory info list stream, or
linux /proc/maps) for this information, and only if the information in
the object files does not conflict with the information in the minidump.

Theoretically that last bit could be improved, since the permissions
obtained from the MemoryList streams is also only a very rough guess,
but it did not seem worthwhile to complicate the implementation because
of that because there will generally be no overlap in practice as the
MemoryList will contain the stack contents and not any module data.

The patch adds a test checking that the module section permissions are
entered into the memory region list, and also a test which demonstrate
that now the unwinder is able to correctly find return addresses even in
minidumps without memory info list streams.

There's one TODO left in this patch, which is that the "memory region"
output does not give any indication about the "don't know" values of
memory region permissions (it just prints them as if they permission bit
was set). I address this in a follow up.

Pavel Labath 9c73925226 [lldb/lit] Introduce %clang_host substitutions
Summary:
This patch addresses an ambiguity in how our existing tests invoke the
compiler. Roughly two thirds of our current "shell" tests invoke the
compiler to build the executables for the host. However, there is also
a significant number of tests which don't build a host binary (because
they don't need to run it) and instead they hardcode a certain target.

We also have code which adds a bunch of default arguments to the %clang
substitutions. However, most of these arguments only really make sense
for the host compilation. So far, this has worked mostly ok, because the
arguments we were adding were not conflicting with the target-hardcoding
tests (though they did provoke an occasional "argument unused" warning).

However, this started to break down when we wanted to use
target-hardcoding clang-cl tests (D69031) because clang-cl has a
substantially different command line, and it was getting very confused
by some of the arguments we were adding on non-windows hosts.

This patch avoid this problem by creating separate %clang(xx,_cl)_host
substutitions, which are specifically meant to be used for compiling
host binaries. All funny host-specific options are moved there. To
ensure that the regular %clang substitutions are not used for compiling
host binaries (skipping the extra arguments) I employ a little
hac^H^H^Htrick -- I add an invalid --target argument to the %clang
substitution, which means that one has to use an explicit --target in
order for the compilation to succeed.

(The normal CONTEXT struct has a different layout on each architecture.
In addition to this, a WOW64_CONTEXT struct always is defined, that
can store the CPU state of an x86_32 process, to allow handling it from
an x86_64 process. But there's no similar universally available struct

Vedant Kumar 82d3ba87d0 [debugserver] Detect arch from LLVM_DEFAULT_TARGET_TRIPLE
The debugserver build needs to conditionally include files depending on the
target architecture.

Switch on the architecture specified by LLVM_DEFAULT_TARGET_TRIPLE, as
the llvm and swift build systems use this variable to identify the
target (the latter, indirectly, through LLVM_HOST_TRIPLE).

It would be possible to switch on CMAKE_OSX_ARCHITECTURES, but the swift
build does not provide it, preferring instead to pass arch-specific
CFLAGS etc explicitly. Switching on LLVM_HOST_TRIPLE is also an option,
but it breaks down when cross-compiling.

Lawrence D'Anna 40b0fa7ef2 [LLDB][formatters] ArgInfo::count -> ArgInfo::max_positional_args
Summary:
Move breakpoints from the old, bad ArgInfo::count to the new, better
ArgInfo::max_positional_args.   Soon ArgInfo::count will be no more.

This functionality is tested in `TestFormatters.py`, `TestDataFormatterSynthVal.py`,
`TestDataFormatterSynthType.py`.

You may notice that the old code was passing 0 arguments when count was 1, and passing
1 argument when count is 2.

This is no longer necessary because max_positional_args counts the self pointer
correctly.

Pavel Labath 7c603a41e2 lldb/minidump: Refactor memory region computation code
The goal of this refactor is to enable ProcessMinidump to take into
account the loaded modules and their sections when computing the
permissions of various ranges of memory, as discussed in D66638.

This patch moves some of the responsibility for computing the ranges
from MinidumpParser into ProcessMinidump. MinidumpParser still does the
parsing, but ProcessMinidump becomes responsible for answering the
actual queries about memory ranges. This will enable it (in a follow-up
patch) to augment the information obtained from the parser with data
obtained from actual object files.

The changes in the actual code are fairly straight-forward and just
involve moving code around. MinidumpParser::GetMemoryRegions is renamed
to BuildMemoryRegions to emphasize that it does no caching. The only new
thing is the additional bool flag returned from this function. This
indicates whether the returned regions describe all memory mapped into
the target process. Data obtained from /proc/maps and the MemoryInfoList
stream is considered to be exhaustive. Data obtained from Memory(64)List
is not. This will be used to determine whether we need to augment the
data or not.

This reshuffle means that it is no longer possible/easy to test some of
this code via unit tests, as constructing a ProcessMinidump instance is
hard. Instead, I update the unit tests to only test the parsing of the
actual data, and test the answering of queries through a lit test using
the "memory region" command. The patch also includes some tweaks to the
MemoryRegion class to make the unit tests easier to write.

Pavel Labath 73a7a55c0e lldb/COFF: Create a separate "section" for the file header
In an attempt to ensure that every part of the module's memory image is
accounted for, D56537 created a special "container section" spanning the
entire image. While that seemed reasonable at the time (and it still
mostly does), it did create a problem of what to put as the "file size"
of the section, because the image is not continuous on disk, as we
generally assume (which is why I put zero there). Additionally, this
arrangement makes it unclear what kind of permissions should be assigned
to that section (which is what my next patch does).

To get around these, this patch partially reverts D56537, and goes back
to top-level sections. Instead, what I do is create a new "section" for
the object file header, which is also being loaded into memory, though
its not considered to be a section in the strictest sense. This makes it
possible to correctly assign file size section, and we can later assign
permissions to it as well.

Jim Ingham 738af7a624 Add the ability to pass extra args to a Python breakpoint callback.
For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and
    it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no
    way to write a generic "stop when my caller is..." function, and then specify the caller when you add the
    command to a breakpoint.

    With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in
    the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right
    signature) when the breakpoint is hit. Then in lldb, you can say:

    (lldb) break com add -F caller_is -k caller_name -v Foo

    More generally this will allow us to write reusable Python breakpoint commands.

Vedant Kumar 0877dd14e4 [Driver] Force llvm to install its handlers before lldb's
Install llvm's signal handlers up front to prevent lldb's handlers from being
ignored. This is (hopefully) a stopgap workaround.

When lldb invokes an llvm API that installs signal handlers (e.g.
llvm::sys::RemoveFileOnSignal, possibly via a compiler embedded within lldb),
lldb's signal handlers are overriden if llvm is installing its handlers for the
first time.

To work around llvm's behavior, force it to install its handlers up front, and
*then* install lldb's handlers. In practice this is used to prevent lldb test
processes from exiting due to IO_ERR when SIGPIPE is received.

Note that when llvm installs its handlers, it 1) records the old handlers it
replaces and 2) re-installs the old handlers when its new handler is invoked.
That means that a signal not explicitly handled by lldb can fall back to being
handled by llvm's handler the first time it is received, and then by the
default handler the second time it is received.

Pavel Labath 96601ec28b ValueObject: Fix a crash related to children address type computation
Summary:
This patch fixes a crash encountered when debugging optimized code. If some
variable has been completely optimized out, but it's value is nonetheless known,
the compiler can replace it with a DWARF expression computing its value. The
evaluating these expressions results in a eValueTypeHostAddress Value object, as
it's contents are computed into an lldb buffer. However, any value that is
obtained by dereferencing pointers in this object should no longer have the
"host" address type.

Lldb had code to account for this, but it was only present in the
ValueObjectVariable class. This wasn't enough when the object being described
was a struct, as then the object holding the actual pointer was a
ValueObjectChild. This caused lldb to dereference the contained pointer in the
context of the host process and crash.

Though I am not an expert on ValueObjects, it seems to me that this children
address type logic should apply to all types of objects (and indeed, applying
applying the same logic to ValueObjectChild fixes the crash). Therefore, I move
this code to the base class, and arrange it to be run everytime the value is
updated.

The test case is a reduced and simplified version of the original debug info
triggering the crash. Originally we were dealing with a local variable, but as
these require a running process to display, I changed it to use a global one
instead.

Summary:
When users define a debugger command from python, they provide a callable

The rule it was using to decide was weird, apparently not tested, and
giving wrong results for some kinds of python callables.

This patch replaces the weird rule with a simple one: if the callable can
take 5 arguments, it gets the 5 argument version of the signature.
Otherwise it gets the old 4 argument version.

It also adds tests with a bunch of different kinds of python callables
with both 4 and 5 arguments.

Vedant Kumar 32ce14e55e Disable exit-on-SIGPIPE in lldb
Occasionally, during test teardown, LLDB writes to a closed pipe.
Sometimes the communication is inherently unreliable, so LLDB tries to
avoid being killed due to SIGPIPE (it calls `signal(SIGPIPE, SIG_IGN)`).
However, LLVM's default SIGPIPE behavior overrides LLDB's, causing it to
exit with IO_ERR.

Opt LLDB out of the default SIGPIPE behavior. I expect that this will
resolve some LLDB test suite flakiness (tests randomly failing with
IO_ERR) that we've seen since r344372.

Pavel Labath 0c30491774 SystemInitializerCommon fix compilation on linux
C++ defines two overloads of std::iscntrl. One in <cctype> and one in
<locale>. On linux we seem to include both which makes the std::erase_if
call ambiguous.

Wrap std::iscntrl call in a lambda to ensure regular overload
resolution.

Lawrence D'Anna 03819d1c80 eliminate one form of PythonObject::Reset()
Summary:
I'd like to eliminate all forms of Reset() and all public constructors
on these objects, so the only way to make them is with Take<> and Retain<>
and the only way to copy or move them is with actual c++ copy, move, or
assignment.

This is a simple place to start.

Lawrence D'Anna c86a6acaee clean up the implementation of PythonCallable::GetNumArguments
Summary:
The current implementation of PythonCallable::GetNumArguments
is not exception safe, has weird semantics, and is just plain
incorrect for some kinds of functions.

Python 3.3 introduces inspect.signature, which lets us easily
query for function signatures in a sane and documented way.

This patch leaves the old implementation in place for < 3.3,
but uses inspect.signature for modern pythons.   It also leaves
the old weird semantics in place, but with FIXMEs grousing about
it.   We should update the callers and fix the semantics in a
subsequent patch.    It also adds some tests.

Raphael Isemann 69b3363a53 [lldb] X-fail tests that use constructors in expressions on Windows
These tests were testing a bug related to constructors. It seems that
on Windows the expression command can't construct objects (or at least,

this is just x-failing them until Windows actually supports constructor calls.

Jonas Devlieghere a0f6c6434c [test] Add a .clang-format file for the shell test.
The API tests have a .clang-format file that disables formatting
altogether. While this is needed for some tests, it also leads to
inconsistency between test files. The shell tests suffer from a similar
problem: a test with a source-file extension (.c, .cpp) will get
formatted, potentially breaking up lines and leading to invalid RUN
commands.

Rather than completely disabling formatting here, I propose to not
enforce a line limit instead. That way tests will be consistent, but you
can still have long run commands (as is not uncommon in LLVM either) and
use breakpoints with patters that extend beyond 80 cols.

Martin Storsjo 95980409e6 [LLDB] [test] Use %clang_cl instead of build.py in a few tests
This allows explicitly specifying the intended target architecture,
for tests that aren't supposed to be executed, and that don't
require MSVC headers or libraries to be available.

(These tests already implicitly assumed to be built for x86; one
didn't specify anything, assuming x86_64, while the other specified
--arch=32, which only picks the 32 bit variant of the default target
architecture).

Join two comment lines in disassembly.cpp, to keep row numbers
checked in the test unchanged.

This fixes running check-lldb on arm linux.

Raphael Isemann 6237c9fe6c [lldb] Don't emit artificial constructor declarations as global functions
Summary:
When we have a artificial constructor DIE, we currently create from that a global function with the name of that class.
That ends up causing a bunch of funny errors such as "must use 'struct' tag to refer to type 'Foo' in this scope" when
doing `Foo f`. Also causes that constructing a class via `Foo()` actually just calls that global function.

The fix is that when we have an artificial method decl, we always treat it as handled even if we don't create a CXXMethodDecl
for it (which we never do for artificial methods at the moment).

Fixes rdar://55757491 and probably some other radars.

Fangrui Song 56ee31964f SBCommandReturnObject: change LLDB_RECORD_METHOD(..., FILE *, ...) to use LLDB_RECORD_DUMMY
POSIX says FILE is a typedef to a structure containing information about
a file. The structure is unspecified, i.e. it may be an incomplete type, as is the case on musl
(`struct _IO_FILE` is an implementation detail that is not exposed).

`LLDB_RECORD_METHOD(..., (FILE *), ...)` transitively uses sizeof(FILE)
and requires the structure to be complete.  Change it to
LLDB_RECORD_DUMMY to fix the build failure on musl (regression of
D57475).

Make it possible to pass a build and install RPATH to
add_lldb_executable instead of having to call lldb_setup_rpaths after

This fixes a real issue where setting an install RPATH with

to be orthogonal to installation components. Regardless, it makes sense

Lawrence D'Anna b07823f3e2 update ScriptInterpreterPython to use File, not FILE*
Summary:
ScriptInterpreterPython needs to save and restore sys.stdout and
friends when LLDB runs a python script.

It currently does this using FILE*, which is not optimal.  If
whatever was in sys.stdout can not be represented as a FILE*, then
it will not be restored correctly when the script is finished.

It also means that if the debugger's own output stream is not
representable as a file, ScriptInterpreterPython will not be able
to redirect python's  output correctly.

This patch updates ScriptInterpreterPython to represent files with
lldb_private::File, and to represent whatever the user had in
sys.stdout as simply a PythonObject.

This will make lldb interoperate better with other scripts or programs
that need to manipulate sys.stdout.

Walter Erquinigo d04855f820 [lldb-server/android] Show more processes by relaxing some checks
By default `platform process list` only shows the processes of the current user that lldb-server can parse.
There are several problems:
- apk programs don't have an executable file. They instead use a package name as identifier. We should show them instead.
- each apk also runs under a different user. That's how android works
- because of the user permission, some files like /proc/<pid>/{environ,exe} can't be read.

This results in a very small process list.

However, I have 700 processes running at this time.

By implementing a few fallbacks for android, I've expanded this list to 202, filtering out kernel processes, which would presumably appear in this list if the device was rooted.

Something to notice is that the architecture is unkonwn for all apks. And that's fine, because run-as would be required to gather this information and that would make this entire functionality massively slow.

There are still several improvements to make here, like displaying actual user names, which I'll try to do in a following diff.

Note: Regarding overall apk debugging support from lldb. I'm planning on having lldb spawn lldb-server by itself with the correct user, so that everything works well. The initial lldb-server used for connecting to the remote platform can be reused for such purpose. Furthermore, eventually lldb could also launch that initial lldb-server on its own.

Lawrence D'Anna 9efbc564ba build fix for SBInstruction.
oops!  I cherry-picked  rL374820 thinking it was completely
independent of D68737, but it wasn't.  It makes an incidental
use of SBFile::GetFile, which is introduced there, so I broke the
build.

The docs say you can commit without review for "obvious".   I think
this qualifies.   If this kind of fix isn't considered obvious, let
me know and I'll revert instead.

Lawrence D'Anna e7a9115680 remove FILE* bindings from SBInstruction.
Summary:
This patch replaces the FILE* python bindings for SBInstruction and
SBInstructionList and replaces them with the new, safe SBFile and FileSP
bindings.

I also re-enable `Test_Disassemble_VST1_64`, because now we can use
the file bindings as an additional test of the disassembler, and we
can use the disassembler test as a test of the file bindings.

The bugs referred to in the comments appear to have been fixed.   The
radar is closed now and the bugzilla bug does not reproduce with the
instructions given.

Lawrence D'Anna d5768e3d0e Fix test breakage caused by r374424
Summary:
The build directory name is based on the test method name, so having
two test methods with the same name in the same test file is a
problem, even if they're in different test classes.

On linux and darwin this conflict can go unnoticed, but windows
has different filesystem semantics and it will fail when one
process tries to delete files still held open by another.

The problem is fixed just by changing the name of one of the test
methods.

Pavel Labath 5a8db84964 DWARFExpression: Fix/add support for (v4) debug_loc base address selection entries
The DWARFExpression is parsing the location lists in about five places.
Of those, only one actually had proper support for base address
selection entries.

Since r374600, llvm has started to produce location expressions with
base address selection entries more aggresively, which caused some tests
to fail.

This patch adds support for these entries to the places which had it
missing, fixing the failing tests. It also adds a targeted test for the
two of the three fixes, which should continue testing this functionality
even if the llvm output changes. I am not aware of a way to write a
targeted test for the third fix (DWARFExpression::Evaluate).

BumpPtrAllocator allocates in 4KiB chunks, which with any larger
project is going to result in a large number of allocations.
Increasing allocation size this way can save 10%-20% of symbol
load time for a huge C++ project with correctly built debuginfo.

Lawrence D'Anna b3faa01ff9 IOHandler: fall back on File::Read if a FILE* isn't available.
Summary:
IOHandler needs to read lines of input from a lldb::File.
The way it currently does this using, FILE*, which is something
we want to avoid now.   I'd prefer to just replace the FILE* code
with calls to File::Read, but it contains an awkward and
delicate workaround specific to ctrl-C handling on windows, and
it's not clear if or how that workaround would translate to
lldb::File.

So in this patch, we use use the FILE* if it's available, and only
fall back on File::Read if that's the only option.

I think this is a reasonable approach here for two reasons.  First
is that interactive terminal support is the one area where FILE*
can't be avoided.   We need them for libedit and curses anyway,
and using them here as well is consistent with that pattern.

The second reason is that the comments express a hope that the
underlying windows bug that's being worked around will be fixed one
day, so hopefully when that happens, that whole path can be deleted.

While useful the TranslationUnitDecl::print(...) method gives us a higher level view then the dump from ASTDumper which is what we get when we invoke dump() on a specific AST node.
The main motivation for this change is allow us to verify that the AST nodes we create when we parse DWARF. For example in order to verify we are correctly using DIFlagExportSymbols added by D66667

Pavel Labath a8b18baa0f ProcessInstanceInfoMatch: Don't match processes with no name if a name match was requested, take 2
Summary:
The previous attempt at making nameless process not match when searching for a
given name failed because the macos implementation was depending on this detail
in its partial matching strategy. Doing partial matching to avoid expensive
lookups is a perfectly valid thing to do, the way it was implemented seems
somewhat unexpected.

This patch implements it differently by providing special
methods in the ProcessInstanceInfoMatch which match only a subset of fields,
and changes mac host code to use those instead.

Then, it re-applies r373925 to get make the ProcessInstanceInfoMatch with a
name *not* match a nameless process.

Aleksandr Urakov 30c2441a32 [Windows] Use information from the PE32 exceptions directory to construct unwind plans
This patch adds an implementation of unwinding using PE EH info. It allows to
get almost ideal call stacks on 64-bit Windows systems (except some epilogue
cases, but I believe that they can be fixed with unwind plan disassembly
augmentation in the future).

To achieve the goal the CallFrameInfo abstraction was made. It is based on the
DWARFCallFrameInfo class interface with a few changes to make it less
DWARF-specific.

To implement the new interface for PECOFF object files the class PECallFrameInfo
was written. It uses the next helper classes:

- UnwindCodesIterator helps to iterate through UnwindCode structures (and
  processes chained infos transparently);
- EHProgramBuilder with the use of UnwindCodesIterator constructs EHProgram;
- EHProgram is, by fact, a vector of EHInstructions. It creates an abstraction
  over the low-level unwind codes and simplifies work with them. It contains
  only the information that is relevant to unwinding in the unified form. Also
  the required unwind codes are read from the object file only once with it;
- EHProgramRange allows to take a range of EHProgram and to build an unwind row
  for it.

So, PECallFrameInfo builds the EHProgram with EHProgramBuilder, takes the ranges
corresponding to every offset in prologue and builds the rows of the resulted
unwind plan. The resulted plan covers the whole range of the function except the
epilogue.

Raphael Isemann 423c2e98e4 [lldb] Fix crash in CxxModuleHandler when std module is empty
We currently don't handle the error in the Expected we get
when searching for an equal local DeclContext. Usually this can't
happen as this would require that we have a STL container and
we can find libc++'s std module, but when we load the module in
the expression parser the module doesn't even contain the 'std'
namespace. The only way I see to test this is by having a fake
'std' module that requires a special define to actually provide
its contents, while it will just be empty (that is, it doesn't
even contain the 'std' namespace) without that define. LLDB currently
doesn't know about that define in the expression parser, so it
will load the wrong 'empty' module which should trigger this error.

Also removed the 'auto' for that variable as the function name
doesn't make it obvious that this is an expected and not just
a optional/ptr (which is how this slipped in from the start).

in `llvm::Expected<>`, but this requires the objects to be correctly
initialized before accessing them.

To fix the crashes, use `llvm::Optional<>` for the members (as indicated
by labath), and use local variables to store the return values of
`LaunchThread` and `StartMonitoringChildProcess`.  Then, only assign to
the member variables after checking if the return values indicated
success.

Jonas Devlieghere 0a186d0f64 [test] Add timeout to API tests.
Before the reorganiziation, the API tests were inheriting the timeout
from the top-level lit file. Now that this is no longer the case, the
lldb-api test suite needs to set its own timeout.

Lawrence D'Anna ab1cd65f19 update TestRunCommandInterpreterAPI to use SBFile
Summary:
If you look at what this test is doing, it's actually quite
mysterious why it works at all.   It sets the input file
inside a "with open".   As soon as the with block ends,
that file will be closed.   And yet somehow LLDB reads
commands from it anyway.    What's actually happening is that
the file descriptor gets dup'd when something inside LLDB
calls File::GetStream().   I think it's fair to say that
what this test is doing is illegal and it has no right
to expect it to work.

This patch updates the test with two cases.  One uses
the SBFile api, and actually transfers ownership of
the original file descriptor to the debugger.   The other
just uses the old FILE* API, but in a sane way.

I also set NO_DEBUG_INFO_TESTCASE, because this test doesn't
use any debug info and doesn't need to run three times.

Adrian Prantl 418893d8f2 Speed up accelerator table lookups
When debugging a large program like clang and doing "frame variable
*this", the ValueObject pretty printer is doing hundreds of scoped
FindTypes lookups. The ones that take longest are the ones where the
DWARFDeclContext ends in something like ::Iterator which produces many
false positives that need to be filtered out *after* extracting the
DIEs. This patch demonstrates a way to filter out false positives at
the accerator table lookup step.

With this patch
  lldb clang-10 -o "b EmitFunctionStart" -o r -o "f 2" -o "fr v *this" -b -- ...

Jonas Devlieghere 27c23653ae [test] Use a different module cache for Shell and API tests.
Before the test reorganization, everything was part of a single test
suite with a single module cache. Now that things are properly separated
this is no longer the case. Only the shell tests inherited the logic to
properly configure and wipe the module caches. This patch adds that
logic back for the API tests. While doing so, I noticed that we were
configuring a Clang module cache in CMake, but weren't actually using it
from dotest.py. I included a fix for that in this patch as well.

Raphael Isemann f5b2b76008 [lldb] Make sure import-std-module/sysroot actually passes for the right reasons
This test was previously passing because myabs was actually emitted into the
debug information and we called that. The test itself was broken as it didn't
use the libc++ directory structure (the /v1/ directory was just called /include/).

This patch gives myabs a default argument which we can't get from debug information
and inlines the function to make sure we can't call it from LLDB without loading
the C++ module.

this was supposed to be, so let's just remove it.
