adc5043fa2 TestIndirectSymbols: Modernize the Makefile
This old test used a completely hand-rolled Makefile. Modernize so that
it's able to cross-compile. And XFAIL the test as it fails on embedded

0156be59b4 Fix a crasher due to an assert when two files have the same UUID but different paths.
Summary: The PlaceholderObjectFile has an assert in SetLoadAddress that fires if "m_base == value" is not true. To avoid this, we create check that the base address matches, and if it doesn't we clear the module that was found using the UUID so that we create a new PlaceholderObjectFile. Added a test to cover this issue.

b24022cd72 SBFile: add a bunch of tests that should eventually work.
Summary:
It's really annoying and confusing to have to keep referring
back to earlier versions of this SBFile work to find the
tests that need to be added for each patch, and not duplicate
them with new tests.

This patch just imports all my tests.   A bunch of them don't
work yet, so they are marked to be skipped.   They'll be
unmarked as I fix them.

One of these tests will actually trip an assert in the SWIG
code now instead of just failing, so I'm fixing that here too.

b56e3a1723 Add test coverage to printing of enums and fix display of unsigned values
TestCPP11EnumTypes.py should have covered all our bases when it comes
to typed enums, but it missed the regression introduced in r374066.
The reason it didn't catch it is somewhat funny: the test was copied
over from another test that recompiled a source file with a different
base type every time, but neither the test source nor the python code
was adapted for testing enums. As a result, this test was just running
8 times the exact same checks on the exact same binary.

This commit fixes the coverage and addresses the issue revealed by
the new tests.

3fb4e49a68 [Testsuite] Get rid of most of the recursive shared library Makefiles
Most of the secondary Makefiles we have are just a couple variable
definitions and then an include of Makefile.rules. This patch removes
most of the secondary Makefiles and replaces them with a direct
invocation of Makefile.rules in the main Makefile. The specificities
of each sub-build are listed right there on the recursive $(MAKE)
call. All the variables that matter are being passed automagically by
make as they have been passed on the command line. The only things you
need to specify are the variables customizating the Makefile.rules
logic for each image.

This patch also removes most of the clean logic from those Makefiles
and from Makefile.rules. The clean rule is not required anymore now
that we run the testsuite in a separate build directory that is wiped
with each run. The patch leaves a very crude version of clean in
Makefile.rules which removes everything inside of $(BUILDDIR). It does
this only when the $(BUILDDIR) looks like a sub-directory of our
standard testsuite build directory to be extra safe.

41ff39605e Add pretty printing of Clang "bitfield" enums
Summary:
Using enumerators as flags is standard practice. This patch adds
support to LLDB to display such enum values symbolically, eg:

(E) e1 = A | B

If enumerators don't cover the whole value, the remaining bits are
displayed as hexadecimal:

(E) e4 = A | 0x10

Detecting whether an enum is used as a bitfield or not is
complicated. This patch implements a heuristic that assumes that such
enumerators will either have only 1 bit set or will be a combination
of previous values.

This patch doesn't change the way we currently display enums which the
above heuristic would not consider as bitfields.

dotest.py currently requires a filterspec to be of the

`test_method`.

This makes it more convenient to just copy a test name

6e1a0cf46b [platform process list] add a flag for showing the processes of all users
Summary:
For context: https://reviews.llvm.org/D68293

We need a way to show all the processes on android regardless of the user id.
When you run `platform process list`, you only see the processes with the same user as the user that launched lldb-server. However, it's quite useful to see all the processes, though, and it will lay a foundation for full apk debugging support from lldb.

Before:
```
PID    PARENT USER       TRIPLE                   NAME
====== ====== ========== ======================== ============================
3234   1                 aarch64-unknown-linux-android adbd
8034   3234              aarch64-unknown-linux-android sh
9096   3234              aarch64-unknown-linux-android sh
9098   9096              aarch64-unknown-linux-android lldb-server
(lldb) ^D
```

Now:
```
(lldb) platform process list -x
205 matching processes were found on "remote-android"
PID    PARENT USER       TRIPLE                   NAME
====== ====== ========== ======================== ============================

I was writing an SB API client and it was crashing on:
	bool DoExecute(SBDebugger dbg, char **command, SBCommandReturnObject &result) {
	  result = subcommand(dbg, "help");

That is because SBCommandReturnObject &result gets initialized inside LLDB by:
	bool DoExecute(Args &command, CommandReturnObject &result) override {
	  // std::unique_ptr gets initialized here from `&result`!!!
	  SBCommandReturnObject sb_return(&result);
	  DoExecute(...);

51e0bbb02d [lldb][modern-type-lookup] No longer import temporary declarations into the persistent AST
Summary:
As we figured out in D67803, importing declarations from a temporary ASTContext that were originally from a persistent ASTContext
causes a bunch of duplicated declarations where we end up having declarations in the target AST that have no associated ASTImporter that
can complete them.

I haven't figured out how/if we can solve this in the current way we do things in LLDB, but in the modern-type-lookup this is solvable
as we have a saner architecture with the ExternalASTMerger. As we can (hopefully) make modern-type-lookup the default mode in the future,
I would say we try fixing this issue here. As we don't use the hack that was reinstated in D67803 during modern-type-lookup, the test case for this
is essentially just printing any kind of container in `std::` as we would otherwise run into the issue that required a hack like D67803.

What this patch is doing in essence is that instead of importing a declaration from a temporary ASTContext, we instead check if the
declaration originally came from a persistent ASTContext (e.g. the debug information) and we directly import from there. The ExternalASTMerger
is already connected with ASTImporters to these different sources, so this patch is essentially just two parts:
1. Mark our temporary ASTContext/ImporterSource as temporary when we import from the expression AST.
2. If the ExternalASTMerger sees we import from the expression AST, instead of trying to import these temporary declarations, check if we
can instead import from the persistent ASTContext that is already connected. This ensures that all records from the persistent source actually
come from the persistent source and are minimally imported in a way that allows them to be completed later on in the target AST.

The next step is to run the ASTImporter for these temporary expressions with the MinimalImport mode disabled, but that's a follow up patch.

This patch fixes most test failures with modern-type-lookup enabled by default (down to 73 failing tests, which includes the 22 import-std-module tests
which need special treatment).

This is the first step in a project to enable arbitrary python
io.IOBase file objects -- including those that override the read()

Currently this is impossible because python file objects must first

6f9f8f411f [lldb][modern-type-lookup] Add two basic tests for modern-type-lookup
The story so far: LLDB's modern type lookup mode has no (as in, 0%) test
coverage. It was supposed to be tested by hardcoding the default to 'true' and then running
the normal LLDB tests, but to my knowledge no one is doing that. As a around 130 tests
seem to fail with this mode enabled, we also can't just enable it globally for now.

As we touch the surrounding code all the time and also want to refactor parts of it, we
should be a bit more ambitious with our testing efforts.

So this patch adds two basic tests that enable this mode and do some
basic expression parsing which should hopefully be basic enough to not
break anywhere but still lets us know if this mode works at all (i.e. setting up the
ExternalASTMerger in LLDB, using its basic import functionality to move declarations
around and do some lookups).

cb4cda2d45 [CMake] Copy over the system debugserver when using LLDB_USE_SYSTEM_DEBUGSERVER
r366433 broke support for the system debugserver. Although the change
was well-intended, it (presumably) unintentionally removed the logic to
copy over the debugserver. As a result, even with
LLDB_USE_SYSTEM_DEBUGSERVER enabled, we ended up building, signing and
using the just-built debugserver.

This patch partially recovers the old behavior: when
LLDB_USE_SYSTEM_DEBUGSERVER is set we don't build debugserver and just
copy over the system one.

9379d19ff8 [lldb] Decouple importing the std C++ module from the way the program is compiled
Summary:
At the moment, when trying to import the `std` module in LLDB, we look at the imported modules used in the compiled program
and try to infer the Clang configuration we need from the DWARF module-import. That was the initial idea but turned out to
cause a few problems or inconveniences:

* It requires that users compile their programs with C++ modules. Given how experimental C++ modules are makes this feature inaccessible
for many users. Also it means that people can't just get the benefits of this feature for free when we activate it by default
(and we can't just close all the associated bug reports).
* Relying on DWARF's imported module tags (that are only emitted by default on macOS) means this can only be used when using DWARF (and with -glldb on Linux).
* We essentially hardcoded the C standard library paths on some platforms (Linux) or just couldn't support this feature on other platforms (macOS).

This patch drops the whole idea of looking at the imported module DWARF tags and instead just uses the support files of the compilation unit.
If we look at the support files and see file paths that indicate where the C standard library and libc++ are, we can just create the module
configuration this information. This fixes all the problems above which means we can enable all the tests now on Linux, macOS and with other debug information
than what we currently had. The only debug information specific code is now the iteration over external type module when -gmodules is used (as `std` and also the
`Darwin` module are their own external type module with their own files).

The meat of this patch is the CppModuleConfiguration which looks at the file paths from the compilation unit and then figures out the include paths
based on those paths. It's quite conservative in that it only enables modules if we find a single C library and single libc++ library. It's still missing some
test mode where we try to compile an expression before we actually activate the config for the user (which probably also needs some caching mechanism),
but for now it works and makes the feature usable.

c9e902406f [lldb] Fix that importing decls in a TagDecl end up in wrong declaration context (partly reverts D61333)
Summary:
In D61333 we dropped some code from ClangASTSource that checks if imported declarations
ended up in the right DeclContext. While this code wasn't tested by the test suite (or better, it was hit
by the test suite but we didn't have any checks that were affected) and the code seems pointless
(as usually Decls should end up in the right DeclContext), it actually broke the data formatters in LLDB
and causes a bunch of obscure bugs where structs suddenly miss all their members. The first report we got about
this was that printing a std::map doesn't work anymore when simply doing "expr m" (m is the std::map).

This patch reverts D61333 partly and reintroduces the check in a more stricter way (we actually check now that
we *move* the Decl and it is in a single DeclContext). This should fix all the problems we currently have until
we figure out how to properly fix the underlying issues. I changed the order of some std::map formatter tests
which is currently the most reliable way to test this problem (it's a tricky setup, see description below).

Fixes rdar://55502701 and rdar://55129537

--------------------------------------

Some more explanation what is actually going on and what is going wrong:

The situation we have is that if we have a `std::map m` and do a `expr m`, we end up seeing an empty map
(even if `m` has elements). The reason for this is that our data formatter sees that std::pair<int, int> has no
members. However, `frame var m` works just fine (and fixes all following `expr m` calls).

The reason for why `expr` breaks std::map is that we actually copy the std::map nodes in two steps in the
three ASTContexts that are involved: The debug information ASTContext (D-AST), the expression ASTContext
we created for the current expression (E-AST) and the persistent ASTContext we use for our $variables (P-AST).

When doing `expr m` we do a minimal import of `std::map` from D-AST to E-AST just do the type checking/codegen.
This copies std::map itself and does a minimal.import of `std::pair<int, int>` (that is, we don't actually import
the `first` and `second` members as we don't need them for anything). After the expression is done, we take
the expression result and copy it from E-AST to P-AST. This imports the E-AST's `std::pair` into P-AST which still
has no `first` and `second` as they are still undeserialized. Once we are in P-AST, the data formatter tries to
inspect `std::map` (and also `std::pair` as that's what the elements are) and it asks for the `std::pair` members.
We see that `std::pair` has undeserialized members and go to the ExternalASTSource to ask for them. However,
P-ASTs ExternalASTSource points to D-AST (and not E-AST, which `std::pair` came from). It can't point to E-AST
as that is only temporary and already gone (and also doesn't actually contain all decls we have in P-AST).

So we go to D-AST to get the `std::pair` members. The ASTImporter is asked to copy over `std::pair` members
and first checks if `std::pair` is already in P-AST. However, it only finds the std::pair we got from E-AST, so it
can't use it's map of already imported declarations and does a comparison between the `std::pair` decls we have
Because the ASTImporter thinks they are different declarations, it creates a second `std::pair` and fills in the
members `first` and `second` into the second `std::pair`. However, the data formatter is looking at the first
`std::pair` which still has no members as they are in the other decl. Now we pretend we have no declarations
and just print an empty map as a fallback.

The hack we had before fixed this issue by moving `first` and `second` to the first declaration which makes
the formatters happy as they can now see the members in the DeclContext they are querying.

Obviously this is a temporary patch until we get a real fix but I'm not sure what's the best way to fix this.
Implementing that the ClassTemplateSpecializationDecl actually understands that the two std::pair's are the same
decl fixes the issue, but this doesn't fix the bug for all declarations. My preferred solution would be to
complete all declarations in E-AST before they get moved to P-AST (as we anyway have to do this from what I can
tell), but that might have unintended side-effects and not sure what's the best way to implement this.

1442efea9a [lldb] Print better diagnostics for user expressions and modules
Summary:
Currently our expression evaluators only prints very basic errors that are not very useful when writing complex expressions.

For example, in the expression below the user made a type error, but it's not clear from the diagnostic what went wrong:
```
(lldb) expr printf("Modulos are:", foobar%mo1, foobar%mo2, foobar%mo3)
error: invalid operands to binary expression ('int' and 'double')
```

This patch enables full Clang diagnostics in our expression evaluator. After this patch the diagnostics for the expression look like this:

```
(lldb) expr printf("Modulos are:", foobar%mo1, foobar%mo2, foobar%mo3)
error: <user expression 1>:1:54: invalid operands to binary expression ('int' and 'float')
printf("Modulos are:", foobar%mo1, foobar%mo2, foobar%mo3)
                                               ~~~~~~^~~~
```

To make this possible, we now emulate a user expression file within our diagnostics. This prevents that the user is exposed to
our internal wrapper code we inject.

Note that the diagnostics that refer to declarations from the debug information (e.g. 'note' diagnostics pointing to a called function)
will not be improved by this as they don't have any source locations associated with them, so caret or line printing isn't possible.
We instead just suppress these diagnostics as we already do with warnings as they would otherwise just be a context message
without any context (and the original diagnostic in the user expression should be enough to explain the issue).

I don't know what the intent of parts of this test were.  We set a
bunch of breakpoints and ran from one to the other, doing "self.runCmd("thread backtrace")"
then continuing to the next one.  We didn't actually verify the contents of the backtrace,
nor that we hit the breakpoints we set in any particular order.  The only actual test was
to run sel_getName at two of these stops.

So I reduced the test to just stopping at the places where we were actually going to run

Prior to this fix if users tried to read memory from one of these addresses like 0x8048000, they would end up incorrectly reading from the next memory region that actually had a p_filesz which would be 0x00000000f778c000 in this case. This fix correctly doesn't include program headers with zero p_filesz in the ProcessELFCore::m_core_aranges that is used to read memory. I found two cores files that have this same issue and added tests.

6179c0eb0d [Windows] Add support of watchpoints to ProcessWindows
Summary:
This patch adds support of watchpoints to the old `ProcessWindows` plugin.

The `ProcessWindows` plugin uses the `RegisterContext` to set and reset
watchpoints. The `RegisterContext` has some interface to access watchpoints,
but it is very limited (e.g. it is impossible to retrieve the last triggered
watchpoint with it), that's why I have implemented a slightly different
interface in the `RegisterContextWindows`. Moreover, I have made the
`ProcessWindows` plugin responsible for search of a vacant watchpoint slot,
because watchpoints exist per-process (not per-thread), then we can place
the same watchpoint in the same slot in different threads. With this scheme
threads don't need to have their own watchpoint lists, and it simplifies
identifying of the last triggered watchpoint.

Currently it has one implementation for filing bugs on the unwinder. As

45e3ce8d76 [dotest] Centralize initialization commands even more
Summary:
In r367234 we introduced a central place to hold the set up commands for
the various ways we have of launching lldb. However, a number of
commands still remained outside of that.

This patch moves the remaining set up commands into this function, which
allows us to remove manual clang module path setting code in
TestBatchMode.

One unfortunate victim of this approach is TestSTTYBeforeAndAfter which,
due to how it launches lldb (pexpect->expect->lldb), fails get the
quoting right. It would be possible to fix the quoting there, it would be a bit
icky, and none of the commands in this list are really relevant for what this
test is doing, so I just remove the commands outright.

cc5b509b9e Workaround TestConcurrentMany* flakiness in a more pricipled way
The flakiness on our local machines seems to come for a race in the kernel
between task_suspend and the creation of the Mach exceptions for the threads
that hit breakpoints. The debugserver code is written with the assumption
that the kernel will be able to provide us with all the exceptions for a
given task once task_suspend returns. On machines with higher core counts,
this seems not to be the case. The first batch of exceptions we get after
task_suspend does not contain exceptions for all the threads that have hit
a breakpoint, thus they get misreprorted in the first stop packet.

Adding a 1ms timeout to the call that retrieves the batch of exceptions
seems to workaround the issue reliably on our machines, and it shoulnd't
impact standard debugging scenarios too much (a stop will incur an additional
1ms delay). We'll be talking to the kernel team to figure out the right
contract for those APIs.

This patch also reverts part of Jonas' previous workaround for the
issue (r370785).

e5814d78ce [lldb] Limit the amount of zeroes we use for padding when printing small floats
Summary:
We got a radar that printing small floats is not very user-friendly in LLDB as we print them with up to
100 leading zeroes before starting to use scientific notation. This patch changes this by already using
scientific notation when we hit 6 padding zeroes by default and moves this value into a target setting
so that users can just set this number back to 100 if they for some reason preferred the old behaviour.

This new setting is influencing how we format data, so that's why we have to reset the data visualisation
cache when it is changed.

Note that we have always been using scientific notation for large numbers because it seems that
the LLVM implementation doesn't support printing out the padding zeroes for them. I would have fixed
that if it was trivial, but looking at the LLVM implementation for this it seems that this is not as trivial
as it sounds. I would say we look into this if we ever get a bug report about someone wanting to have
a large amount of trailing zeroes in their numbers instead of using scientific notation.

6897a814e6 [lldb] Add description to option completions.
Summary:
Right now our argument completions are rather cryptic for command options as they only list the letters:

```
(lldb) breakpoint set -
Available completions:
	-G
	-C
	-c
	-d
	-i
	-o
	-q
	-t
	-x
[...]
```

With the new completion API we can easily extend this with the flag description so that it looks like this now:

```
(lldb) breakpoint set -
Available completions:
	-G -- The breakpoint will auto-continue after running its commands.
	-C -- A command to run when the breakpoint is hit, can be provided more than once, the commands will get run in order left to right.
	-c -- The breakpoint stops only if this condition expression evaluates to true.
	-d -- Disable the breakpoint.
	-i -- Set the number of times this breakpoint is skipped before stopping.
	-o -- The breakpoint is deleted the first time it stop causes a stop.
	-q -- The breakpoint stops only for threads in the queue whose name is given by this argument.
	-t -- The breakpoint stops only for the thread whose TID matches this argument.
	-x -- The breakpoint stops only for the thread whose index matches this argument.
```

The same happens with --long-options now.

12a7e6c09c dotest: improvements to the pexpect tests
Summary:
While working on r370054, i've found it frustrating that the test output
was compeletely unhelpful in case of failures. Therefore I've decided to
improve that. In this I reuse the PExpectTest class, which was one of
our mechanisms for running pexpect tests, but which has gotten orhpaned
in the mean time.

I've replaced the existing send methods with a "expect" method, which
I've tried to design so that it has a similar interface to the expect
method in regular non-pexpect dotest tests (as it essentially does
something very similar). I've kept the ability to dump the transcript of
the pexpect communication to stdout in the "trace" mode, as that is a
very handy way to figure out what the test is doing. I've also removed
the "expect_string" method used in the existing tests -- I've found this
to be unhelpful because it hides the message that would be normally
displayed by the EOF exception. Although vebose, this message includes
some important information, like what strings we were searching for,
what were the last bits of lldb output, etc. I've also beefed up the
class to automatically disable the debug info test duplication, and
auto-skip tests when the host platform does not support pexpect.

This patch ports TestMultilineCompletion and TestIOHandlerCompletion to
the new class. It also deletes TestFormats as it is not testing anything
(definitely not formats) -- it was committed with the test code
commented out (r228207), and then the testing code was deleted in
r356000.

ff5982aa91 [test] Fix various module cache bugs and inconsistencies
Currently, lit tests don't set neither the module cache for building
inferiors nor the module cache used by lldb when running tests.
Furthermore, we have several places where we rely on the path to the
module cache being always the same, rather than passing the correct
value around. This makes it hard to specify a different module cache
path when debugging a a test.

This patch reworks how we determine and pass around the module cache
paths and fixes the omission on the lit side. It also adds a sanity
check to the lit and dotest suites.

This patch removes the -q (quiet) flag and changing the default

contradictory, as illustrated by the difference between the argument
name (quiet) and the configuration flag (parsable). On the one hand it
reduces output, but on the other hand it prints more output, like the
result of individual tests. My proposal is to guard the extra output
behind the verbose flag and always print the individual test results.

behavior by again allowing partial completions. Also extends the iohandler

7049b0ad4d Stop-hooks weren't getting called on step-out. Fix that.
There was a little bit of logic in the StopInfoBreakpoint::PerformAction
that would null out the StopInfo once we had a completed plan so that the
next call to GetStopInfo would replace it with the StopInfoThreadPlan.

But the stop-hooks check for whether a thread stopped for a reason didn't
trigger this conversion.  So I added an API to do that directly, and then
called it where before we just reset the StopInfo.

Currently the heuristic used in ClangASTContext::CreateRecordType to identify an anonymous class is that there is that name is a nullptr or simply a null terminator. This heuristic is not accurate since it will also sweep up unnamed classes and lambdas. The improved heuristic relies on the requirement that an anonymous class must be contained within a class.

72ef113d40 [API] Have SBCommandReturnObject::GetOutput/Error return "" instead of nullptr
Summary:
It seems this was an unintended side-effect of D26698. AFAICT, these
functions did return an empty string before that patch, and the patch
contained code which attempted to ensure that, but those efforts were
negated by ConstString::AsCString, which by default returns a nullptr
even for empty strings.

This patch:
- fixes the GetOutput/Error methods to really return empty strings
- adds and explicit test for that
- removes a workaround in lldbtest.py, which was masking this problem
  from our other tests

b448d1bf21 [lldb] Fix dynamic_cast by no longer failing on variable without metadata
Summary:
Our IR rewriting infrastructure currently fails when it encounters a variable which has no metadata associated.
This causes dynamic_cast to fail as in this case IRForTarget considers the type info pointers ('@_ZTI...') to be
variables without associated metadata. As there are no variables for these internal variables, this is actually
not an error and dynamic_cast would work fine if we didn't throw this error.

This patch fixes this by removing this diagnostics code. In case we would actually hit a variable that has no
metadata (but is supposed to have), we still have the error in the expression log so this shouldn't make it
harder to diagnose any missing metadata errors.

This patch should fix dynamic_cast and also adds a bunch of test coverage to that language feature.

If a bitfield doesn't fit into the child_byte_size'd window at

here is that Value has no notion of bitfields and thus the Value's
DataExtractor is sized like the bitfields CompilerType; a sequence of
bitfields, however, can be larger than their underlying type.

This was not in the big-endian-derived DWARF 2 bitfield attributes
because their offsets were counted from the end of the window, so they

fa5c340ea1 Fix ClangASTContext::CreateParameterDeclaration to not call addDecl
Summary:
The change https://reviews.llvm.org/D55575 modified ClangASTContext::CreateParameterDeclaration to call decl_ctx->addDecl(decl); this caused a regression since the existing code in DWARFASTParserClang::ParseChildParameters is called with the containing DeclContext. So when end up with cases where we are parsing a parameter for a member function and the parameter is added to the CXXRecordDecl as opposed to the CXXMethodDecl. This example is given in the regression test TestBreakpointInMemberFuncWNonPrimitiveParams.py which without this fix in a modules build leads to assert on setting a breakpoint in a member function with non primitive parameters. This scenario would be common when debugging LLDB or clang.

I was going through some of the old bugs and came across PR21069 which I
was able to reproduce. The issue is that we match the regex `^foo`
against the `DW_AT_name` in the DWARF, which for our anonymous function
is indeed `foo`. However, when we get the function name from the symbol
context, the result is `(anonymous namespace)::foo()`. This throws off
completions, which assumes that it's appending to whatever is already
present on the input, resulting in a bogus
`b fooonymous\ namespace)::foo()`.

e010f6bab3 [lldb] Fix crash when tab-completing in multi-line expr
Summary:
Tab completing inside the multiline expression command can cause LLDB to crash. The easiest way
to do this is to go inside a frame with at least one local variable and then try to complete:

    (lldb) expr
    1. a[tab]

Reason for this was some mixup when we calculate the cursor position. Obviously we should calculate
the offset inside the string by doing 'end - start', but we are doing 'start - end' (which causes the offset to
become -1 which will lead to some out-of-bounds reading).

Fixes rdar://51754005

I don't see any way to test this as the *multiline* expression completion is completely untested at the moment
and I don't think we have any existing code for testing infrastructure for it.

2b38951799 [lldb] Increase testsuite packet-timeout 5secs -> 1min
rL357954 did increase `packet-timeout` 1sec -> 5secs. Which is IMO about the
maximum timeout reasonable for regular use. But for testsuite I think the
timeout should be higher as the testsuite runs in parallel and it can be run
even on slow hosts and with other load (moreover if it runs on some slow arch).

I have chosen 60 secs, that should be enough hopefully.  Larger value could
make debugging with hanging `lldb-server` annoying.

I guess `request_continue` was probably originally intended to be synchronous
but then it isn't and this code has been leftover there.

ca9dfdfaec [lldb] Fix crash when looking up type coming from the ClangModuleDeclVendor
Summary:
We assume in LLDB that every type comes from an ASTContext with an associated ClangASTContext.
However the types inside the ClangModuleDeclVendor don't have a ClangASTContext so we end up
crashing whenever we create a CompilerType for one of these types.

Simplest way to trigger this bug is to just look up NSObject from a module:
   (lldb) expr @import Foundation
   (lldb) type lookup NSObject
   Assertion failed: (m_type_system != nullptr), function CompilerType, file /Users/teemperor/llvm1/llvm-project/lldb/source/Symbol/CompilerType.cpp, line 39.

This patch just creates a ClangASTContext for the ASTContext used by ClangModuleDeclVendor.

e21fc8770c Add offsetof support to expression evaluator.
Summary:
We currently don't support offsetof in the expression evaluator as it is implemented as a macro
(which then calls __builtin_offsetof) in stddef.h. The best solution would be to include that
header (or even better, import Clang's builtin module), but header-parsing and
(cross-platform) importing modules is not ready yet.

Until we get this working with modules I would say we add the macro to our existing macro list
as we already do with other macros from stddef.h/stdint.h. We should be able to drop all of them
once we can import the relevant modules by default.

be4be6120f Add support to ProcessMachCore::DoLoadCore to handle an EFI UUID str.
If a core file has an EFI version string which includes a UUID
(similar to what it returns for the kdp KDP_KERNELVERSION packet)
in the LC_IDENT or LC_NOTE 'kern ver str' load command.  In that
case, we should try to find the binary and dSYM for the UUID
listed.  The dSYM may have python code which knows how to relocate
the binary to the correct address in lldb's target section load
list and loads other ancillary binaries.

The test case is a little involved,

1. it compiles an inferior hello world apple (a.out),
2. it compiles a program which can create a corefile manually
   with a specific binary's UUID encoded in it,
3. it gets the UUID of the a.out binary,
4. it creates a shell script, dsym-for-uuid.sh, which will
   return the full path to the a.out + a.out.dSYM when called
   with teh correct UUID,
5. it sets the LLDB_APPLE_DSYMFORUUID_EXECUTABLE env var before
   creating the lldb target, to point to this dsym-for-uuid.sh,
6. runs the create-corefile binary we compiled in step #2,
7. loads the corefile from step #6 into lldb,
8. verifies that lldb loaded a.out by reading the LC_NOTE
   load command from the corefile, calling dsym-for-uuid.sh with
   that UUID, got back the path to a.out and loaded it.

whew!

aefcf5100a [ASTImporter] Fix LLDB lookup in transparent ctx and with ext src
Summary:
With LLDB we use localUncachedLookup(), however, that fails to find
Decls when a transparent context is involved and the given DC has
external lexical storage.  The solution is to use noload_lookup, which
works well with transparent contexts.  But, we cannot use only the
noload_lookup since the slow case of localUncachedLookup is still needed
in some other cases.

These other cases are handled in ASTImporterLookupTable, but we cannot
use that with LLDB since that traverses through the AST which initiates
the load of external decls again via DC::decls().

We must avoid loading external decls during the import becuase
ExternalASTSource is implemented with ASTImporter, so external loads
during import results in uncontrolled and faulty import.

this test will create a zombie process which in turn leads to a failing test. On my macOS system this happens quite frequently.

This patch fixes this by letting the test synchronize with the inferior after it has started up.

695f7821e2 [lldb_test_suite] Fix lldb test suite targeting remote Android
Summary:
Fixed `Android.rules` for running test suite on remote android
- the build configuration is not compatible with ndk structure, change it to link to static libc++
- generally clang should be able to use libc++ and will link against the right library, but some libc++ installations require the user manually link libc++abi.
- add flag `-lc++abi` to fix the test binary build failure

Added `skipIfTargetAndroid` `skipUnlessTargetAndroid` for better test support
- the `skipIfPlatform` method will ask `lldbplatformutil.getPlatform()` for platform info which is actually the os type, and //Android// is not os type but environment
- create this function to handle the android target condition

**To Run Test on Remote Android**
1 start lldb-server on your devices
2 run lldb-dotest with following configuration:
`./lldb-dotest --out-of-tree-debugserver --arch aarch64 --platform-name remote-android --platform-url connect://localhost:12345 --platform-working-dir /data/local/tmp/ --compiler your/ndk/clang`

has left some of the tests introduced by D62502 broken more or less

the library list near unreadable pages of memory). I attempted to make a
partial fix for this in r364748, but Jan Kratochvil pointed out that

there.

The qemu x86_64 target returns a target.xml register definition file which

be a method that starts the parsing, asking a recurisve function to fetch
and parse target.xml, (3) adds 
ProcessGDBRemote::GetGDBServerRegisterInfoXMLAndProcess which can recusively
call itself to read and parse included xml files, (4) in addition to expecting
the top-level <target> element (which only happens in the top level xml file),
also an xml file that consists of a <feature> node - read the register 
defintions and includes from that <feature> element.

D55859 <https://reviews.llvm.org/D55859> has no effect for some of the

LLDB was failing when LLDB prints errors reading system debug infos

should not be affected by system debug infos.

`lldb/packages/Python/lldbsuite/test/api/multithreaded/driver.cpp.template` is
using only SB API which does not expose `ModuleList` so I had to call
`HandleCommand()` there.

`lldb-test.cpp` could also use `HandleCommand` and then there would be no need
for `ModuleListProperties::SetEnableExternalLookup()` but I think it is cleaner
with API and not on based on text commands.

21929d49d5 Revert "Disable the step over skipping calls feature since buildbots are not happy."
While this fixed the windows bot failures, it also broke all other bots.

Upon closer inspection, it turns out that the windows bots were "broken"
because two tests were unexpectedly passing -- i.e., the original patch
(r360375) actually improved our stepping support on windows.

So instead, I remove the relevant XFAILs.

This reverts commit r360397.

df225764b7 Improve step over performance by not stopping at branches that are function calls and stepping into and them out of each one
Currently when we single step over a source line, we run and stop at every branch in the source line range. We can reduce the number of times we stop when stepping over by figuring out if any of these branches are function calls, and if so, ignore these branches. Since we are stepping over we can safely ignore these calls since they will return to the next instruction. Currently the step logic would stop at those branches (1st stop), single step into the branch (2nd stop), and then set a breakpoint at the return address (3rd stop), and then continue.

e5cbe78259 Fix for ambiguous lookup in expressions between local variable and namespace
Summary:
In an Objective-C context a local variable and namespace can cause an ambiguous name lookup when used in an expression. The solution involves mimicking the existing C++ solution which is to add local using declarations for local variables. This causes a different type of lookup to be used which eliminates the namespace during acceptable results filtering.

Two tests cannot share the same name, because they will generate an
identical trace file. When that happens, this can lead to a race
condition where dotest fails when trying to move both files into the
trace directory, because the file has already been moved. Additionally,
the trace will have been overwritten by the test that finishes last.

71569d0d52 Inject only relevant local variables in the expression evaluation context
Summary:
In r259902, LLDB started injecting all the locals in every expression
evaluation. This fixed a bunch of issues, but also caused others, mostly
performance regressions on some codebases. The regressions were bad
enough that we added a setting in r274783 to control the behavior and
we have been shipping with the setting off to avoid the perf regressions.

This patch changes the logic injecting the local variables to only inject
the ones present in the expression typed by the user. The approach is
fairly simple and just scans the typed expression for every local name.
Hopefully this gives us the best of both world as it just realizes the
types of the variables really used by the expression.

Landing this requires the 2 other issues I pointed out today to be addressed
but I wanted to gather comments right away.

Summary:
This will fix a bug where during expression parsing we are not setting a CXXRecordDecl to not be passed in registers and the resulting code generation is wrong.
The DWARF attribute DW_CC_pass_by_reference tells us that we should not be passing in registers i.e. RAA_Indirect.
This change depends this clang change which fixes the fact that the ASTImporter does not copy RecordDeclBits for CXXRecordDecl: https://reviews.llvm.org/D61140

f74a4c1f6d Instantiate 'std' templates explicitly in the expression evaluator
Summary:
This patch is a follow-up for D58125. It implements the manual instantiation and merging of 'std' templates like
`std::vector` and `std::shared_ptr` with information from the debug info AST. This (finally) allows using these classes
in the expression evaluator like every other class (i.e. things like `vec.size()` and shared_ptr debugging now works, yay!).

The main logic is the `CxxModuleHandler` which intercept the ASTImporter import process and replaces any `std` decls
by decls from the C++ module. The decls from the C++ module are "imported" by just deserializing them directly in
the expression evaluation context. This is mostly because we don't want to rely on the ASTImporter to correctly import
these declarations, but in the future we should also move to the ASTImporter for that.

This patch doesn't contain the automatic desugaring for result variables. This means that if you call for example
`size` of `std::vector` you maybe get some very verbose typedef'd type as the variable type, e.g.
`std::vector<int, std::allocator<int>>::value_type`.

This is not only unreadable, it also means that our ASTImporter has to import all these types and associated
decls into the persisent variable context. This currently usually leads to some assertion getting triggered
in Clang when the ASTImporter either makes a mistake during importing or our debug info AST is inconsitent.
The current workaround I use in the tests is to just cast the result to it's actual type (e.g. `size_t` or `int`) to prevent
the ASTImporter from having to handle all these complicated decls.

The automatic desugaring will be a future patch because I'm not happy yet with the current code for that and because
I anticipate that this will be a controversial patch.
