Make sure that the shell tests use the same python interpreter as the
rest of the build instead of picking up `python` from the PATH.
It would be nice if we could use the _disallow helper, but that triggers
on invocations that specify python as the scripting language.
Rosetta crashlogs can have their own thread register state. Unlike the

In the rush to get the bot green, I did not realize I was building the
file with -gsplit-dwarf, and therefore the yaml ended up referring to a
file I did not check it.
This rebuilds the file without split dwarf.
In D117744, llvm removed writing support for this format, breaking the
test. We may eventually want to remove reading support as well, but for
now I have converted the test to a yaml file to maintain coverage.
This adds inline function support to NativePDB by parsing S_INLINESITE records
to retrieve inlinee line info and add them into line table at `ParseLineTable`.

The pdb lldb tests do not work correctly with both the VS2019 and VS2017 toolsets at the moment. This change updates several of the tests to work with both toolsets. Unfortunately, this makes the tests suboptimal for both toolsets, but we can update them to be better for VS2019 once we officially drop VS2017. This change is meant to bridge the gap until the update happens, so that the buildbots can work with either toolset.

Currently, we'll try to instantiate a ClangREPL for every known

so rely on that to only instantiate a REPL when we know the requested

This implements `DoLoadImage` and `UnloadImage` in the Windows platform
plugin modelled after the POSIX platform plugin. This was previously
unimplemented and resulted in a difficult to decipher error without any
logging.
This implementation is intended to support enables the use of LLDB's
Swift REPL on Windows.
Paths which are added to the library search path are persistent and
applied to all subsequent loads. This can be adjusted in the future by
storing all the cookies and restoring the path prior to returning from
the helper. However, the dynamic path count makes this a bit more
challenging.

minidebuginfo-set-and-hit-breakpoint.test is failing on Arm/Linux most
probably due to an ill formed binary after removal of certain sections
from executable. I am marking it as XFAIL for further investigation.
Only lldb-arm-ubuntu is failing after https://reviews.llvm.org/D114288 and there isn't enough input context to see why this is failing. It works on x86_64 linux just fine.
I don't see a reason why not to. If we allows lookup functions by full names,
I can change the test case in D113930 to use `lldb-test symbols --find=function --name=full::name --function-flags=full ...`,
though the duplicate method decl prolem is still there for `lldb-test symbols --dump-ast`.
That's a seprate bug, we can fix it later.

This implements the following changes:
* AutoType retains sugared deduced-as-type.
* Template argument deduction machinery analyses the sugared type all the way
down. It would previously lose the sugar on first recursion.
* Undeduced AutoType will be properly canonicalized, including the constraint
template arguments.
* Remove the decltype node created from the decltype(auto) deduction.
As a result, we start seeing sugared types in a lot more test cases,
including some which showed very unfriendly `type-parameter-*-*` types.

Teach LLDB to understand INLINE and INLINE_ORIGIN records in breakpad.
They have the following formats:
```
INLINE inline_nest_level call_site_line call_site_file_num origin_num [address size]+
INLINE_ORIGIN origin_num name
```
`INLNIE_ORIGIN` is simply a string pool for INLINE so that we won't have
duplicated names for inlined functions and can show up anywhere in the symbol
file.
`INLINE` follows immediately after `FUNC` represents the ranges of momery
address that has functions inlined inside the function.
Differential Revision: https://reviews.llvm.org/D113330
Since every FUNC record (in breakpad) is a compilation unit, creating the
function for the CU allows `ResolveSymbolContext` to resolve
`eSymbolContextFunction`.

It is surprisingly difficult to write a simple python script that
can reliably `import lldb` without failing, or crashing. I'm
currently resorting to convolutions like this:
def find_lldb(may_reexec=False):
if prefix := os.environ.get('LLDB_PYTHON_PREFIX'):
if os.path.realpath(prefix) != os.path.realpath(sys.prefix):
raise Exception("cannot import lldb.\n"
f" sys.prefix should be: {prefix}\n"
f" but it is: {sys.prefix}")
else:
line1, line2 = subprocess.run(
['lldb', '-x', '-b', '-o', 'script print(sys.prefix)'],
encoding='utf8', stdout=subprocess.PIPE,
check=True).stdout.strip().splitlines()
assert line1.strip() == '(lldb) script print(sys.prefix)'
prefix = line2.strip()
os.environ['LLDB_PYTHON_PREFIX'] = prefix
if sys.prefix != prefix:
if not may_reexec:
raise Exception(
"cannot import lldb.\n" +
f" This python, at {sys.prefix}\n"
f" does not math LLDB's python at {prefix}")
os.environ['LLDB_PYTHON_PREFIX'] = prefix
python_exe = os.path.join(prefix, 'bin', 'python3')
os.execl(python_exe, python_exe, *sys.argv)
lldb_path = subprocess.run(['lldb', '-P'],
check=True, stdout=subprocess.PIPE,
encoding='utf8').stdout.strip()
sys.path = [lldb_path] + sys.path
This patch aims to replace all that with:
#!/usr/bin/env lldb-python
import lldb
...
... by adding the following features:
* new command line option: --print-script-interpreter-info. This
prints language-specific information about the script interpreter
in JSON format.
* new tool (unix only): lldb-python which finds python and exec's it.

The Swift stdlib uses absolute symbols in the dylib to communicate
feature flags to the process. LLDB's expression evaluator needs to be
able to find them. This wires up absolute symbols so they show up in
the symtab lookup command, which is also all that's needed for them to
be visible to the expression evaluator JIT.

In 7f01f78593 [lldb] update TestEchoCommands -- I fixed this test,
but not on windows, becuase I used some unix shell syntax that
doesn't work with cmd.exe. Fixed it so it will work in both.
Test logic is the same.
This is a trivial fix, so bypassing review to get the build clean again
ASAP.

Sorry, I broke this test. The test was verifying the bad behavior
of --source-quietly that the previous change fixed -- namely that
it still echos the initial list of startup commands while
sourcing them.
Updated the test to verify that --source-quietly is quiet, rather than
loud.

Jim says:
lldb has a -Q or --source-quietly option, which supposedly does:
--source-quietly Tells the debugger to execute this one-line lldb command before any file has been loaded.
That seems like a weird description, since we don't generally use source for one line entries, but anyway, let's try it:
> $LLDB_LLVM/clean-mono/build/Debug/bin/lldb -Q "script print('I should be quiet')" a.out -O "script print('I should be before')" -o "script print('I should be after')"
(lldb) script print('I should be before')
I should be before
(lldb) target create "script print('I should be quiet')"
error: unable to find executable for 'script print('I should be quiet')'
That was weird. The first real -O gets sourced but not quietly, then the argument to the -Q gets treated as the target.
> $LLDB_LLVM/clean-mono/build/Debug/bin/lldb -Q a.out -O "script print('I should be before')" -o "script print('I should be after')"
(lldb) script print('I should be before')
I should be before
(lldb) target create "a.out"
Current executable set to '/tmp/a.out' (x86_64).
(lldb) script print('I should be after')
I should be after
Well, that's a little better, but the -Q option seems to have done nothing.

This fixes the description of --source-quietly, as well as causing it
to actually suppress echoing while executing the initialization
commands.

Based on post-commit review discussion on
2bd8493847 with Richard Smith.
Other uses of forcing HasEmptyPlaceHolder to false seem OK to me -
they're all around pointer/reference types where the pointer/reference
token will appear at the rightmost side of the left side of the type
name, so they make nested types (eg: the "int" in "int *") behave as
though there is a non-empty placeholder (because the "*" is essentially
the placeholder as far as the "int" is concerned).
This was originally committed in 277623f4d5
Reverted in f9ad1d1c77 due to breakages
outside of clang - lldb seems to have some strange/strong dependence on
"char [N]" versus "char[N]" when printing strings (not due to that name
appearing in DWARF, but probably due to using clang to stringify type
names) that'll need to be addressed, plus a few other odds and ends in
other subprojects (clang-tools-extra, compiler-rt, etc).
This patch fixes a problem introduced by clang change
https://reviews.llvm.org/D95617 and described by
https://bugs.llvm.org/show_bug.cgi?id=50076#c6, where inlined functions
omit unused parameters both in the stack trace and in `frame var`
command. With this patch, the parameters are listed correctly in the
stack trace and in `frame var` command.
Specifically, we parse formal parameters from the abstract version of
inlined functions and use those formal parameters if they are missing
from the concrete version.
