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 fixes the following warning for developers:
Target 'liblldb' was changed to a FRAMEWORK sometime after install(). This
may result in the wrong install DESTINATION. Set the FRAMEWORK property
earlier.
The solution is to pass the FRAMEWORK flag to add_lldb_library and set
the target property before install(). For now liblldb is the only
customer.

non-cached lookup performance
Performance issues lead to the libc++ std::function formatter to be disabled. We addressed some of those performance issues by adding caching see D67111
This PR fixes the first lookup performance by not using FindSymbolsMatchingRegExAndType(...) and instead finding the compilation unit the std::function wrapped callable should be in and then searching for the callable directly in the CU.

This is basically the same bug as in r260434.
SymbolFileDWARF::FindTypes has exponential worst-case when digging
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
SymbolFiles around.

This warning triggers when a class defines a copy constructor but not a
copy-assignment operator (which then gets auto-generated by the
compiler). Fix the warning by deleting the other operator too, as the
default implementation works just fine.

Summary:
swift-lldb currently has to patch the ExpressionKind enum to add support for Swift expressions. If we implement LLVM's RTTI
with a static ID variable instead of a centralised enum we can drop that patch.

ObjCLanguage::GetPossibleFormattersMatches
We call IsPossibleDynamicType but we also need to check if this is a Clang type,
otherwise other languages with dynamic types (like Swift) might end up being interpreted

Currently nothing prevents you from continuing your debug session after
generating the reproducer. This can cause the reproducer to end up in an
inconsistent state. Most of the time this doesn't matter, but I want to
prevent this from causing bugs in the future.

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.

gcc-9 started warning when a class defined a copy constructor without a
copy assignment operator (or vice-versa).
This fixes those warnings by deleting the other special member too
(after verifying it doesn't do anything non-trivial).

until we can automatically fall back to p/P if g/G are not supported;
it looks like there is a bug in debugserver's g/G packets taht needs
to be fixed, or debugserver should stop supporting g/G until that bug
is fixed. But we need lldb to be able to fall back to p/P correctly
for that to be a viable workaround.

Summary:
All type in these functions need be valid and Clang types, so
we might as well replace these checks with IsClangType.
Also lets IsClangType explicitly check for validity instead of
assuming that the TypeSystem is a nullptr.

after the new module has been added to the target and
the sections have all been adjusted to their actual
load addresses. Solves a problem where an operating
system plugin in the kernel could be loaded multiple
times; the first before the binary had even been

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.

Following up on https://reviews.llvm.org/D62221, this change introduces
the settings plugin.process.gdb-remote.use-g-packet-for-reading. When
they are on, 'g' packets are used for reading registers.
Using 'g' packets can improve performance by reducing the number of
packets exchanged between client and server when a large number of
registers needs to be fetched.

require scanning symbols
Performance issues lead to the libc++ std::function formatter to be disabled.
This change is the first of two changes that should address the performance issues and allow us to enable the formatter again.
In some cases we end up scanning the symbol table for the callable wrapped by std::function for those cases we will now cache the results and used the cache in subsequent look-ups. This still leaves a large cost for the initial lookup which will be addressed in the next change.

Restrict building the readline override to Linux only. It both does not

Fix https://bugs.llvm.org/show_bug.cgi?id=43830 while avoiding polluting the
global Python namespace.
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

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.

Summary:
This patch updates the last user of ArgInfo::count and deletes
it. I also delete `GetNumInitArguments()` and `GetInitArgInfo()`.
Classess are callables and `GetArgInfo()` should work on them.
On python 3 it already works, of course. `inspect` is good.
On python 2 we have to add yet another special case. But hey if
python 2 wasn't crufty we wouln't need python 3.
I also delete `is_bound_method` becuase it is unused.
This path is tested in `TestStepScripted.py`

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.

Summary:
This function is only used internally by ClangExpressionParser. By putting it in the ExpressionParser class all languages
that implement ExpressionParser::Parse have to share the same signature (which forces us in downstream to add
swift-specific arguments to ExpressionParser::Parse which then propagate to ClangExpressionParser and so on).

Normally you shouldn't be able to have a process with an ItaniumABI plugin
that doesn't have this symbol. But if the loader crashes before loading
libc++abi.dylib (on MacOS), then the symbol might not be present. So we
should check before accessing the pointer.
There isn't a good way to write a test for this, but the change is obvious.
