Summary:
MergeFrom was updating the architecture if the target triple did not
have it set. However, it was leaving the core field as invalid. This
resulted in assertion failures in core file tests as a missing core
meant we were unable to compute the address byte size properly.
Add a unit test for the new behaviour.

The test fails because an older clang did not emit the required debug

Summary:
The iteration list through the available data formatters was undefined,
which meant that the vector<bool> formatter kicked in only in cases
where it happened to be queried before the general vector formatter. To
fix this, I merge the two data formatter entries into one, and select
which implementation to use in the factory function.

Displaying the object pointed by the unique_ptr can cause an infinite

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.

This was added to workaround a limitation in LLVM's implementation
of getting the current user's home directory, since it would
only look at the value of $HOME, but we did not want to rely
on that being set so we would also look in the password database.
Adding the ability to look in the password database to LLVM was
a straightforward patch that was submitted in r298513, so since
that is done this test is no longer needed.

Only do this when we are debugging an executable, since we

llvm-svn: 298290
r298203 make SBPlatform::MakeDirectory less recursive, which breaks the
test suite creation of test directory hierarchy creation on the remote
target. Since the function was never fully recursive, and the name does
not imply recursiveness, I fix the problem by modifying the test runner
to do the recursion manually.
I also make the runner complain more loudly when it fails to create the
directory -- previously it just printed the error to stdout and caused
most of the tests to hang, which is not very helpful in diagnosing the
problem.

dotest.py script doesn't validate executables passed on the command line

current process ID, instead of the inferior pid), and remove the NetBSD

It seems that on darwin we are not able to resolve breakpoints in the
test shared library until the process has started. That seems
unfortunate, but it is not the purpose of this test, so work around that
by starting the process before doing the rest of our checks.
llvm-svn: 297830
Summary:
This fixes the case where a user tries to set a breakpoint on a source
line outside of any function (e.g. because that code is #ifdefed out, or
the compiler did not emit code for the function, etc.) and we would
silently move the breakpoint to the next function.
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
filtering only happens if we have full debug info available (e.g. in
case of -gline-tables-only compilation, we still set the breakpoint on
the nearest source line).

Summary:
This has been broken at least since the new test result framework was
added, which was over a year ago. It looks like nobody has missed it
since.
Removing this makes the gmodules handling code saner, as it already did
not know how to handle the multiple-compilers case.
My motivation for this is libc++ data formatters support on android -- I
am trying make a central way of determining whether libc++ tests can be
run, and without this, I would have to resort to similar hacks as the
gmodules code.

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.
llvm-svn: 296870
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.

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.

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.

I also strenghten the test a bit to make sure we actually find all the

functions, but maybe this should be *exactly* 6 ?

r290874 enabled the s390x test, which caused the rest of the tests to start
misbehaving. This is because this test switches the selected platform and the
change persists.

llvm-svn: 290890
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.
