I was over-eager to unable this test in r304976. It still fails in this
combination, at there does not seem to be anything we can do about it,
as the generated code does not preserve the link register.
llvm-svn: 305062
Summary:
When a call instruction is the last instruction in a function, the
backtrace PC will point past the end of the function. We already had
special code to handle that, but we did not handle the case where the PC
ends up outside of the bounds of the module containing the function,
which is a situation that occured in TestNoreturnUnwind on android for
some arch/compiler combinations.
I fix this by adding an argument to Address resolution code which states
that we are ok with addresses pointing to the end of a module/section to
resolve to that module/section.
I create a reproducible test case for this situation by hand-crafting an
executable which has a noreturn function at the end of a module.

When parsing types originating in modules, it is possible to encounter AttributedTypes
(such as the type generated for NSString *_Nonnull). Some of LLDB's ClangASTContext
methods deal with them; others do not. In particular, one function that did not was
GetTypeInfo, causing TestObjCNewSyntax to fail.
This fixes that, treating AttributedType as essentially transparent and getting the
information for the modified type.
In addition, however, TestObjCNewSyntax is a monolithic test that verifies a bunch of
different things, all of which can break independently of one another. I broke it
apart into smaller tests so that we get more precise failures when something (like
this) breaks.

This is a resubmit of r303732, which was reverted due to a regression.
The original patch caused a regression in TestLoadUnload, which has only showed
up when running the remote test suite. The problem there was that we interrupted
the target just as it has hit the rendezvous breakpoint in the dlopen call. This
meant that the stop reason was set to "breakpoint" even though the event would
not have been broadcast if we had not stopped the process. I fix this by
checking StopInfo->ShouldNotify() before stopping.
I also add a new test for the handling of conditional breakpoints in
expressions, which I noticed to be broken (pr33164)
Differential Revision: https://reviews.llvm.org/D33283
llvm-svn: 303848
Summary:
The function had logic to handle the case when the expression terminated
while we were trying to halt the process, but it failed to take into
account the possibility that the expression stopped because it hit a
breakpoint. This was caused by the fact that the handling of the stopped
events was duplicated for the "halting" and regular cases (the regular
case handled this situation correctly). I've tried to merge these two
cases into one to make sure they stay in sync.
I should call out that the two cases were checking whether the thread
plan has completed in slightly different ways. I am not sure what is the
difference between them, but I think the check should be the same in
both cases, whatever it is, so I just took the one from the regular
case, as that is probably more tested.
For the test, I modified TestUnwindExpression to run the expression with
a smaller timeout (this is how I found this bug originally). With a 1ms
one thread timeout, the test failed consistently without this patch.

Templates can end in parameter packs, like this
template <class T...> struct MyStruct
{ /*...*/ };
LLDB does not currently support these parameter packs;
it does not emit them into the template argument list
at all. This causes problems when you specialize, e.g.:
template <> struct MyStruct<int>
{ /*...*/ };
template <> struct MyStruct<int, int> : MyStruct<int>
{ /*...*/ };
LLDB generates two template specializations, each with
no template arguments, and then when they are imported
by the ASTImporter into a parser's AST context we get a
single specialization that inherits from itself,
causing Clang's record layout mechanism to smash its
stack.
This patch fixes the problem for classes and adds
tests. The tests for functions fail because Clang's
ASTImporter can't import them at the moment, so I've
xfailed that test.

Loading a shared library can require a large amount of work; rather than do that serially for each library,

llvm-svn: 301609
Many times a user wants to access a type when there's a variable of
the same name, or a variable when there's a type of the same name.
Depending on the precise context, currently the expression parser
can fail to resolve one or the other.
This is because ClangExpressionDeclMap has logic to limit the
amount of information it searches, and that logic sometimes cuts
down the search prematurely. This patch removes some of those early
exits.
In that sense, this patch trades performance (early exit is faster)
for correctness.
I've also included two new test cases showing examples of this
behavior – as well as modifying an existing test case that gets it
wrong.
llvm-svn: 301273
LLDB uses clang::DeclContexts for lookups, and variables get put into
the DeclContext for their abstract origin. (The abstract origin is a
DWARF pointer that indicates the unique definition of inlined code.)
When the expression parser is looking for variables, it locates the
DeclContext for the current context. This needs to be done carefully,
though, e.g.:
__attribute__ ((always_inline)) void f(int a) {
{
int b = a * 2;
}
}
void g() {
f(3);
}
Here, if we're stopped in the inlined copy of f, we have to find the
DeclContext corresponding to the definition of f – its abstract
origin. Clang doesn't allow multiple functions with the same name and
arguments to exist. It also means that any variables we see must be
placed in the appropriate DeclContext.
[Bug 1]: When stopped in an inline block, the function
GetDeclContextDIEContainingDIE for that block doesn't properly
construct a DeclContext for the abstract origin for inlined
subroutines. That means we get duplicated function DeclContexts, but
function arguments only get put in the abstract origin's DeclContext,
and as a result when we try to look for them in nested contexts they
aren't found.
[Bug 2]: When stopped in an inline block, the DWARF (for space
reasons) doesn't explicitly point to the abstract origin for that
block. This means that the function GetClangDeclContextForDIE returns
a different DeclContext for each place the block is inlined. However,
any variables defined in the block have abstract origins, so they
will only get placed in the DeclContext for their abstract origin.
In this fix, I've introduced a test covering both of these issues,
and fixed them.
Bug 1 could be resolved simply by making sure we look up the abstract
origin for inlined functions when looking up their DeclContexts on
behalf of nested blocks.
For Bug 2, I've implemented an algorithm that makes the DeclContext
for a block be the containing DeclContext for the closest entity we
would find during lookup that has an abstract origin pointer. That
means that in the following situation:
{ // block 1
int a;
{ // block 2
int b;
}
}
if we looked up the DeclContext for block 2, we'd find the block
containing the abstract origin of b, and lookup would proceed
correctly because we'd see b and a. However, in the situation
{ // block 1
int a;
{ // block 2
}
}
since there isn't anything to look up in block 2, we can't determine
its abstract origin (and there is no such pointer in the DWARF for
blocks). However, we can walk up the parent chain and find a, and its
abstract origin lives in the abstract origin of block 1. So we simply
say that the DeclContext for block 2 is the same as the DeclContext
for block 1, which contains a. Lookups will return the same results.

Summary:
This aims to replace the different decorators we've had on each libc++
test with a single solution. Each libc++ will be assigned to the
"libc++" category and a single central piece of code will decide whether
we are actually able to run libc++ test in the given configuration by
enabling or disabling the category (while giving the user the
opportunity to override this).
I started this effort because I wanted to get libc++ tests running on
android, and none of the existing decorators worked for this use case:
- skipIfGcc - incorrect, we can build libc++ executables on android
with gcc (in fact, after this, we can now do it on linux as well)
- lldbutil.skip_if_library_missing - this checks whether libc++.so is
loaded in the proces, which fails in case of a statically linked
libc++ (this makes copying executables to the remote target easier to
manage).
To make this work I needed to split out the pseudo_barrier code from the
force-included file, as libc++'s atomic does not play well with gcc on
linux, and this made every test fail, even though we need the code only
in the threading tests.
So far, I am only annotating one of the tests with this category. If
this does not break anything, I'll proceed to update the rest.

Now we check whether the line range of the resolved symbol context
function matches the original line number. We reject any breakpoint
locations that appear to move the breakpoint into a new function. This

libstdc++ tests together, which previously was not possible because
make_standalone_toolchain bakes in the STL to use during toolchain
creation time. The support for this is not present yet -- this change
only make sure we don't regress for existing funcionality (gcc w/
libstdc++). Clang and libc++ support will be added later.
I've checked that the mips android targets compile after this change,
but I have no way of checking whether this breaks anything. If you are

sufficiently simple now that if we wish to log something extremely

In the case we are stepping over the thread creation instruction, we
will end up calling Thread::SingleStep back-to-back twice (because of
the intermediate PTRACE_EVENT_CLONE stop). This will cause the cpu mask
to be set inappropriately (because the old SingleStepCheck object will
be destroyed after we create the new one), and the single-step will
fail.
Before the refactor the code was still incorrect in this case, but in a
different way (the thread was left with the incorrect mask after the
stepping was complete), so this was not easy to spot.
This fixes TestCreateDuringInstructionStep on the affected devices.

r290874 enabled the s390x test, which caused the rest of the tests to start

Summary:
This patch changes and simplifies the way notes are read from Linux Elf cores.
The current implementation copies the bytes from the notes directly over the lldb structure for 64 bit cores and reads field by field for 32 bit cores. Reading the bytes directly only works if the endianess of the core dump and the platform that lldb are running on matches. The case statements for s390x and x86_64 would would only work on big endian systems and little endian systems respectively. That meant that x86_64 generally worked but s390x didn't unless you were on s390x or another big endian platform.
This patch just reads field by field on all platform and updates the field by field version to allow for those fields which are word size instead of fixed size. It should also slightly simplify adding support for a new Linux platform.
This patch also re-enables the s390x test case in TestLinuxCore.py on all non-s390x platforms as it now passes.

when we've interrupted the process).

Summary:
This patch changes the way ProcessElfCore.cpp handles signal information.
The patch changes ProcessElfCore.cpp to use the signal from si_signo in SIGINFO notes in preference to the value of cursig in PRSTATUS notes. The value from SIGINFO seems to be more thread specific. The value from PRSTATUS is usually the same for all threads even if only one thread received a signal.
If it cannot find any SIGINFO blocks it reverts to the old behaviour and uses the value from cursig in PRSTATUS. If after that no thread appears to have been stopped it forces the status of the first thread to be SIGSTOP to prevent lldb hanging waiting for any thread from the core file to change state.
The order is:
- If one or more threads have a non-zero si_signo in SIGINFO that will be used.
- If no threads had a SIGINFO block with a non-zero si_signo set all threads signals to the value in cursig in their PRSTATUS notes.
- If no thread has a signal set to a non-zero value set the signal for only the first thread to SIGSTOP.
This resolves two issues. The first was identified in bug 26322, the second became apparent while investigating this problem and looking at the signal values reported for each thread via “thread list”.
Firstly lldb is able to load core dumps generated by gcore where each thread has a SIGINFO note containing a signal number but cursig in the PRSTATUS block for each thread is 0.
Secondly if a SIGINFO note was found the “thread list” command will no longer show the same signal number for all threads. At the moment if a process crashes, for example with SIGILL, all threads will show “stop reason = signal SIGILL”. With this patch only the thread that executed the illegal instruction shows that stop reason. The other threads show “stop reason = signal 0”.

Summary:
The floating-point and SSE registers could be present in the elf-core
file in the note NT_FPREGSET for 64 bit ones, and in the note
NT_PRXFPREG for 32 bit ones.
The entire note is a binary blob matching the layout of the x87 save
area that gets generated by the FXSAVE instruction (see Intel developers
manual for more information).
This CL mainly modifies the RegisterRead function in
RegisterContextPOSIXCore_x86_64 for it to return the correct data both
for GPR and FPR/SSE registers, and return false (meaning "this register
is not available") for other registers.
I added a test to TestElfCore.py that tests reading FPR/SSE registers
both from a 32 and 64 bit elf-core file and I have inluded the source
which I used to generate the core files.
I tried to also add support for the AVX registers, because this info could
also be present in the elf-core file (note NT_X86_XSTATE - that is the result of
the newer XSAVE instruction). Parsing the contents from the file is
easy. The problem is that the ymm registers are split into two halves
and they are in different places in the note. For making this work one
would either make a "hacky" approach, because there won't be
any other way with the current state of the register contexts - they
assume that "this register is of size N and at offset M" and
don't have the notion of discontinuos registers.

inspect local variables, show image list, do memory reads, etc.
For now the only arches that this supports are x86_32 and x86_64.
This is because I have only written register contexts for those.

This tests that lldb handles the situation when a single instruction triggers

lldb-server bug (pr30758).

This reverts commit r284795, as it breaks watchpoint handling on arm (and
presumable all architectures that report watchpoint hits without executing the

There seems to be something fundamentally wrong with this patch: it uses
process_sp->AddPreResumeAction to re-enable the watchpoint, but the whole point
of the step-over-watchpoint logic (which AFAIK is the only user of this class) is
to disable the watchpoint *after* we resume to do the single step.

Summary:
This plugin resembles the already existing Windows-only Minidump plugin.
The WinMinidumpPlugin uses the Windows API for parsing Minidumps
while this plugin is cross-platform because it includes a Minidump
parser (which is already commited)
It is able to produce a backtrace, to read the general puprose regiters,
inspect local variables, show image list, do memory reads, etc.
For now the only arch that this supports is x86 64 bit
This is because I have only written a register context for that arch.
Others will come in next CLs.
I copied the WinMinidump tests and adapted them a little bit for them to
work with the new plugin (and they pass)
I will add more tests, aiming for better code coverage.
There is still functionality to be added, see TODOs in code.

Summary:
This patch is necessary because individual test cases are not required
to have unique names. Therefore, test cases must now
be specified explicitly in the form <TestCase>.<TestMethod>.
Because it works by regex matching, passing just <TestCase> will
still disable an entire file.
This also allows for multiple exclusion files to be specified.

The lldbutil.run_break_set_by_file_and_line has already checked that the number of
locations was 1, so don't check it again. And certainly don't check it again by
grubbing in break list output.
Also, we know the Thread's IsStopped state is wrong, and have a test for that, so
don't keep testing it in other files where that isn't the primary thing we're testing.
I removed the xfail for Darwin. If this also passes on other systems, we can remove
the xfails from them as we find that out.

This change addresses the corner case bug in the test
infrastructure where a test file times out *outside*
of any running test method. In those cases, the issue
was charged to the file, not to a test method within
the file. When that file is re-run successfully,
none of the test-method-level successes would clear
the file-level issue.
This change fixes that: for all test files that are
getting rerun (whether by being marked flaky or
via the --rerun-all-issues flag), file-level test
issues are searched for in each of those files. Each
file-level issue found in the rerun file list then
gets cleared.
A test of this feature is added to issue_verification,
using the technique there of moving the *.py.park file
to *.py to do an end-to-end validation.
This change also adds a .gitignore entry for pyenv
project-level files and fixes up a few minor pep8
formatting violations in files I touched.

Remove the test for thread stopped states from this test.
That isn't set properly now, and its setting doesn't matter till we actually support non-stop debugging, so
we shouldn't have unrelated tests failing from it.
Also changed some code that was trying and failing to grub command line output, and replaced
it by SB API calls.

We only use the .o-style debug info here regardless, so having
it run all three debuginfo styles was a waste.
This also strips out the custom build function and uses the
TestBase.build() method.
