Summary:
When creating a test with `lldbinline.MakeInlineTest()`, the reported `inspect.getfile(test.__class__)` is `lldbtest.pyc`, meaning any `.categories` file will be ineffective for those tests. Check for the test_filename first, which inline tests will set.
Additionally, raise an error with the starting dir if `.categories` is not found. This makes the problem more obvious when it occurs: when the test is separated from the test framework tree.

Summary:
This was causing problems on linux, where we'd end up calling the
deleting destructor instead of a regular one (because they have the same
demangled name), making a lot of mischief in the process.
The only place where this was necessary (according to the test suite, at
least) was to call a base structor instead of a complete one, but this
is now handled in a more targeted fashion.
TestCallOverriddenMethod is now re-enabled as it now passes reliably.

This replaces `include $(LEVEL)/Makefile.rules` with `include Makefile.rules`.
The lldb test driver already passes the include path when running make, and specifically looking for "../../Makefile.rules" forces the test to be in a specific location.
Removing this hardcoded relative path will make it possible to move this test as-is.
options class. This value was hanging around so for instance if you made a scripted breakpoint
resolver, then went to set another breakpoint, it would still think you had passed in a class
name and the breakpoint wouldn't do what you expected.
Summary:
Using a BreakpointList corrupts the breakpoints' IDs because
BreakpointList::Add sets the ID, so use a vector instead, and
update the signature to return the vector wrapped in an
llvm::Expected which can propagate any error from the inner
call to StringIsBreakpointName.
Note that, despite the similar name, SBTarget::FindBreakpointsByName
doesn't suffer the same problem, because it uses a SBBreakpointList,
which is more like a BreakpointIDList than a BreakpointList under the
covers.
Add a check to TestBreakpointNames that, without this fix, notices the
ID getting mutated and fails.

Summary:
Previously the ABI plugin exposed some "register infos" and the
gdb-remote code used those to fill in the missing bits. Now, the
"filling in" code is in the ABI plugin itself, and the gdb-remote code
just invokes that.
The motivation for this is two-fold:
a) the "augmentation" logic is useful outside of process gdb-remote. For
instance, it would allow us to avoid repeating the register number
definitions in minidump code.
b) It gives more implementation freedom to the ABI classes. Now that
these "register infos" are essentially implementation details, classes
can use other methods to obtain dwarf/eh_frame register numbers -- for
instance they can consult llvm MC layer.
Since the augmentation code was not currently tested anywhere, I took
the opportunity to create a simple test for it.

The idea is to remove front-end analysis for the parameter's value
modification and leave it to the value tracking system. Front-end in some
cases marks a parameter as modified even the line of code that modifies the
parameter gets optimized, that implies that this will cover more entry
values even. In addition, extending the support for modified parameters
will be easier with this approach.
Since the goal is to recognize if a parameter’s value has changed, the idea
at very high level is: If we encounter a DBG_VALUE other than the entry
value one describing the same variable (parameter), we can assume that the
variable’s value has changed and we should not track its entry value any
more. That would be ideal scenario, but due to various LLVM optimizations,
a variable’s value could be just moved around from one register to another
(and there will be additional DBG_VALUEs describing the same variable), so
we have to recognize such situation (otherwise, we will lose a lot of entry
values) and salvage the debug entry value.

This reverts commit c9ddb02659.
Fix handling concurrent watchpoint events so that they are reported
correctly in LLDB.
If multiple watchpoints are hit concurrently, the NetBSD kernel reports
them as series of SIGTRAPs with a thread specified, and the debugger
investigates DR6 in order to establish which watchpoint was hit. This
is normally fine.
However, LLDB disables and reenables the watchpoint on all threads after
each hit, which results in the hit status from DR6 being wiped.
As a result, it can't establish which watchpoint was hit in successive
SIGTRAP processing.
In order to workaround this problem, clear DR6 only if the breakpoint
is overwritten with a new one. More specifically, move cleaning DR6
from ClearHardwareWatchpoint() to SetHardwareWatchpointWithIndex(),
and do that only if the newly requested watchpoint is different
from the one being set previously. This ensures that the disable-enable
logic of LLDB does not clear watchpoint hit status for the remaining
threads.
This also involves refactoring of watchpoint logic. With the old logic,
clearing watchpoint involved wiping dr6 & dr7, and setting it setting
dr{0..3} & dr7. With the new logic, only enable bit is cleared
from dr7, and the remaining bits are cleared/overwritten while setting
new watchpoint.

NetBSD ptrace interface does not populate watchpoints to newly-created
threads. Solve this via copying the watchpoints from the current thread
when new thread is reported via TRAP_LWP.
Add a test that verifies that when the user does not have permissions
to set watchpoints on NetBSD, the 'watchpoint set' errors out gracefully

Implement major improvements to multithreaded program support. Notably,
support tracking new and exited threads, associate signals and events
with correct threads and support controlling individual threads when
resuming.
Firstly, use PT_SET_EVENT_MASK to enable reporting of created and exited
threads via SIGTRAP. Handle TRAP_LWP events to keep track
of the currently running threads.
Secondly, update the signal (both generic and SIGTRAP) handling code
to account for per-thread signals correctly. Signals delivered
to the whole process are reported on all threads, while per-thread
signals and events are reported only to the specific thread.
The remaining threads are marked as 'stopped with no reason'. Note that
NetBSD always stops all threads on debugger events.
Thirdly, implement the ability to set every thread as running, stopped
or single-stepping separately while continuing the process. This also
provides the ability to send a signal to the whole process or to one
of its thread while resuming.
Differential Revision: https://reviews.llvm.org/D70022
Summary:
The test used a non-stopping "run" command to launch the process. This
is different from the regular launch with no extra launch commands,
which uses eLaunchFlagStopAtEntry to ensure that the process stops
straight away.
I'm not really sure what's supposed to happen in non-stop-at-entry mode,
or if that's even supported, but what ended up happening was the launch
packet got a reply while the process was running. Then the test case did
a continue_to_next_stop(), which queued a *second* resume request
(along with the internal "resumes" which were being issued as a part of
normal process startup). These two resumes ended up chasing each other's
tails inside lldb in a way which produced hilarious log traces.
Surprisingly, the test ended up passing most of the time, but it did
cause spurious failures when the test seemed to miss a breakpoint.
This changes the test to use stop-at-entry mode in the manual launch
sequence too, which seems to be enough to make the test pass reliably.

This affects -gmodules only.
Under normal operation pcm_type is a shallow forward declaration
that gets completed later. This is necessary to support cyclic
data structures. If, however, pcm_type is already complete (for
example, because it was loaded for a different target before),
the definition needs to be imported right away, too.
Type::ResolveClangType() effectively ignores the ResolveState
inside type_sp and only looks at IsDefined(), so it never calls
ClangASTImporter::ASTImporterDelegate::ImportDefinitionTo(),
which does extra work for Objective-C classes. This would result
in only the forward declaration to be visible.
An alternative implementation would be to sink this into Type::ResolveClangType ( 88235812a7/lldb/source/Symbol/Type.cpp (L5809)) though it isn't clear to me how to best do this from a layering perspective.

Summary:
expect() forwards its command to sendline(). This can be problematic if the command already contains a newline: sendline() unconditionally adds a newline to the command, which causes the command to run twice (hitting enter in lldb runs the previous command). The expect() helper looks for the prompt and finds the first one, but because the command has run a second time, the buffer will contain the contents of the second time the command ran, causing potential erroneous matching.

To run the testsuite remotely the executable needs to be uploaded to

When the test uses additional shared libraries, those won't be handled

Calling this API requires a target, so it doesn't mesh well with the

the registration automatically when running a remote

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.

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.

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

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.

We essentially test libc++ in a sysroot here so let's make sure
that we actually only run this test on platforms where libc++
testing is enabled.
llvm-svn: 374572
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).
llvm-svn: 374525
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.

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 -- ...

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.

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.

the exceptions returned differ between swig4 (TypeError) and swig<=3
(NotImplementedError). Just check for the base Exception class instead.
Theoretically we could switch on the swig version and expect the precise
