This test #include's stdio.h, which, on at least two bots results in a

Stale global module caches cause problems for the bots. The modules
become invalid when clang headers are updated by version control, and
tests which use these modules fail to compile, e.g:
fatal error: file '.../__stddef_max_align_t.h' has been modified since the module file '/var/.../Darwin.pcm' was built
note: please rebuild precompiled header '/var/.../Darwin.pcm'
Eventually we should transition to having just a single module cache to speed
tests up. This patch should be just enough to fix the spurious bot failures due
to stale caches.

Summary:
There was some confusion in the code about how to represent process
environment. Most of the code (ab)used the Args class for this purpose,
but some of it used a more basic StringList class instead. In either
case, the fact that the underlying abstraction did not provide primitive
operations for the typical environment operations meant that even a
simple operation like checking for an environment variable value was
several lines of code.
This patch adds a separate Environment class, which is essentialy a
llvm::StringMap<std::string> in disguise. To standard StringMap
functionality, it adds a couple of new functions, which are specific to
the environment use case:
- (most important) envp conversion for passing into execve() and likes.
Instead of trying to maintain a constantly up-to-date envp view, it
provides a function which creates a envp view on demand, with the
expectation that this will be called as the very last thing before
handing the value to the system function.
- insert(StringRef KeyEqValue) - splits KeyEqValue into (key, value)
pair and inserts it into the environment map.
- compose(value_type KeyValue) - takes a map entry and converts in back
into "KEY=VALUE" representation.
With this interface most of the environment-manipulating code becomes
one-liners. The only tricky part was maintaining compatibility in
SBLaunchInfo, which expects that the environment entries are accessible
by index and that the returned const char* is backed by the launch info
object (random access into maps is hard and the map stores the entry in
a deconstructed form, so we cannot just return a .c_str() value). To
solve this, I have the SBLaunchInfo convert the environment into the
"envp" form, and use it to answer the environment queries. Extra code is
added to make sure the envp version is always in sync.
(This also improves the layering situation as Args was in the Interpreter module
whereas Environment is in Utility.)

Two tests were failing because the debugger was picking up multiply

there should be no ambiguity because the tests are defining variables

exchange I create a self-contained test which reproduces the issue

Some tests are failing on macOS when building with the in-tree
clang, and this is because they're conditional on the version released.
Apple releases using a different versioning number, but as these are
conditional on clang < 7, they fail for clang ToT (which is 6.0).
As a general solution, we actually need either a mapping between
Apple internal release version and public ones.
That said, I discussed this with Fred , and Apple Clang 6.0 seems
to be old enough that we can remove this altogether (which means I

A bunch of tests were already setting these flags manually, but here

such test) can turn it off explicitly via

Summary:
New linux kernels (on systems that support the XSAVES instruction) will
not update the inferior registers unless the corresponding flag in the
XSAVE header is set. Normally this flag will be set in our image of the
XSAVE area (since we obtained it from the kernel), but if the inferior
has never used the corresponding register set, the respective flag can
be clear.
This fixes the issue by making sure we explicitly set the flags
corresponding to the registers we modify. I don't try to precisely match
the flags to set on each write, as the rules could get quite complicated
-- I use a simpler over-approximation instead.
This was already caught by test_fp_register_write, but that was only
because the code that ran before main() did not use some of the register
sets. Since nothing in this test relies on being stopped in main(), I
modify the test to stop at the entry point instead, so we can be sure
the inferior did not have a chance to access these registers.

executable, which ensures that all parts of the library needed to
evaluate the expressions are always present.

Summary:
The test incremented an atomic varible to trigger the watchpoint event.
On arm64 this compiled to a ldaxr/stlxr loop, with the watchpoint being
triggered in the middle of the loop. Hitting the watchpoint resets the
exclusive monitor, and forces the process to loop one more time, hitting
the watchpoint again, etc.
While it would be nice if the debugger was able to resume from this
situation, this is not trivial, and is not what this test is about.
Therefore, I propose to change this to a simple store to a normal
variable (which should still trip the watchpoint everywhere, but without
atomic loops) and file a bug to investigate the possibilities of
handling the watchpoints in atomic loops in a more reasonable way.

through CommandInterpreter::WasInterrupted().

When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.
This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint. It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names. There is also full support for
then in the SB API, including a new SBBreakpointName class.
The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well. This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.
You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.
I also added the ability to make hidden and delete/disable protected
names. When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.
This feature will allow GUI's that need to use breakpoints for their

The DWO handling code can get confused by clang modules which also use

In NativeProcessLinux::MonitorSIGTRAP we were asserting that the si_code
value is one of the codes we know about. However, that list was very
incomplete -- for example, we were not handling SI_TKILL/SI_USER,
generated by raise(SIGTRAP). A cursory examination show there are at
least a dozen codes like these that an app can generate, and more can be
added at any point.
So, instead of trying to play catchup, I change the default behavior to
treat an unknown si_code like an ordinary signal. The only reason we
needed to inspect si_code in the first place is because
watchpoint/breakpoints are notified as SIGTRAP, but we already know
about those, and us starting to use a new debug event is far less likely
than somebody introducing a new non-debug event.
I add a test case to TestRaise to verify we are handling raise(SIGTRAP)
in an application properly.

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 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

tests are still not passing due to several other problems, but this way
we can at least build them.

SectionLoadList exposed by this test. Greg tried to chase it down
& got pretty far but the isn't correct so we'll disable this test
for now until I can figure that out.

The toolchain directory for arm android targets was computed
incorrectly. The architecture part should be arm, and the environment
part androideabi. This fixes that.

it fails, but it works on the local workstations. I'll
need to figure out what the difference is between these.

Currently on remote platforms the lldb-mi tests fail, which means they time out.
Given how many of the lldb-mi tests there are, this means a long wait.

Prior to MSVC 2015 we had to manually include this header any
time we were going to include <thread> or <future> due to a
bug in MSVC's STL implementation. This has been fixed in MSVC
for some time now, and we require VS 2015 minimum, so we can
remove this across all subprojects.

$(realpath), which I guess is a make builtin, gives strange results on
Windows. $(shell realpath) invokes the gnuwin external binary, which
works correctly.

Make sure we don't generate extremely long file names for test trace log
file, as this can cause path-too-long errors. As the compilers in the
android ndk are deeply nested, it's very easy to trigger these.
I chose to output at most 4 path components -- this should keep the full
path for common cases like /usr/bin/gcc with room to spare, and should
be enough to uniquely identify the compiler for more deeply nested
cases.

Summary:
This teaches the test makefiles about the Android NDK, so we are able to
run the tests without first going through the make_standalone_toolchain
script. The motivation for this is the ability to run both libc++ and
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
reading this and it broke you, let me know.

this test was using the VPATH hack to avoid having a copy of the
inferior source code. This makes the test fail if in happens to run
concurrently with a test in the parent folder. Fix that by moving it up
to the parent.

Summary:
Native Thread ID is retrieved with _lwp_self() on NetBSD.
The returned value is of type int32_t, but for consistency with other Operating Systems cast it to uint64_t.

Summary:
There is nothing we can do with the breakpoint once the associated
target becomes deleted. This will make sure we don't hold on to more
resources than we need in this case. In particular, this fixes the case
TestStepOverBreakpoint on windows, where a lingering SBBreakpoint object
causes us to nor unmap the executable file from memory.

acquired only after checking if the ivar shared pointer was already
filled in. But when I assign an UnwindPlan object to the shared
pointer, I assign an empty object and then fill it in. That leaves
a window where another thread could get the shared pointer to the
empty (but quickly being-filled-in) object and lead to a crash.
Also two changes from Greg for correctness on the TestMultipleDebuggers
test case.

Summary:
This also removes magic rename code, which caused the channel to be
called "linux" when built on a linux machine, and "freebsd" when built
on a freebsd one, which seems unnecessary - registering a new channel is
sufficiently simple now that if we wish to log something extremely
os-specific, we can just create a new channel. None of the current
categories seem very specific to one OS or another.

The testsuite's results formatter maintains a result_status_counts
structure solely for the purpose of setting the return status code
after the testsuite has run. This data is redundant with the
result_events structure that contains the results of individual
tests.
There are subtle bugs arising from this redundancy that make some
builds report no errors but a nonzero status. Rather than try to
make sure these two are always in agreement, I've just rewritten
the code that used to use the counts to now use the per-test
results.
