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!

Now that we correctly ignore ASCII escape sequences when colors are
disabled (r362240), I'd like to change the default frame and thread
format to include color in their output, in line with the syntax
highlighting that Raphael added a while ago.
This patch adds highlighting for the stop reason, the file, line and
column number. With colors disabled, this of course is a no-op.

The code commited in r355764 didn't do what I want as I typed GetThreadID

This is not a fix, but if I understand enough of the issue, it should
bail out early of the test when in a situation that would result in
a failure down the road.

The last round of logging taught us that when the test fails, lldb
is indeed aware of the thread it's failing to associate to a given
queue. Add more logging to try to figure out why the thread and the
queue do not appear related to the Queue APIs.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

The test suite has often unnecessary trailing whitespace, and sometimes
unnecessary trailing lines or a missing final new line. This patch just strips
trailing whitespace/lines and adds missing newlines at the end.

On Darwin, the binary's symbol table points to debug info in object
files -- potentially object files within a static library. Such a
library may have multiple entries with the same name, distinguished
only by timestamp.
The code was already _attempting_ to handle this case (see the code in
ObjectContainerBSDArchive::Archive::FindObject which disambiguates via
timestamp). But, unfortunately, while the timestamp was taken into
account on the _first_ lookup, the result was then cached in a map
keyed only off of the path.
Added the timestamp to the cache, and added a test case.

Summary:
This patch implements a unified way of cleaning the build folder of each
test. This is done by completely removing the build folder before each
test, in the respective setUp() method. Previously, we were using a
combination of several methods, each with it's own drawbacks:
- nuking the entire build tree before running dotest: the issue here is
that this did not take place if you ran dotest manually
- running "make clean" before the main "make" target: this relied on the
clean command being correctly implemented. This was usually true, but
not always.
- for files which were not produced by make, each python file was
responsible for ensuring their deleting, using a variety of methods.
With this approach, the previous methods become redundant. I remove the
first two, since they are centralized. For the other various bits of
clean-up code in python files, I indend to delete it when I come
across it.

This test was only testing that clang produced the correct informations
for __apple accelerated tables. So, it's a clang test. Also, it
doesn't require any debugger intervention, the object file can
be analyzed statically with a dumper. Also, the input program
was highly verbose (unnecessarily).
r325850 commits a clang test instead, so it's time to retire this.

This test was accessing self.debug_info, which doesn't exist anymore. For
some reason the macOS bots are skipping this test because they think the

This patch makes LLDB's clang module cache path customizable via

This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.
For each test (should be eventually: each test configuration) a
separate build directory is created and we execute
make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test
In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.
Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.

Normal customer devices won't be able to run these tests, we're hoping to get
a public facing bot set up at some point. Both devices pass the testsuite without
any errors or failures.
I have seen some instability with the armv7 test runs, I may submit additional patches
to address this. arm64 looks good.
I'll be watching the bots for the rest of today; if any problems are introduced by
this patch I'll revert it - if anyone sees a problem with their bot that I don't
see, please do the same. I know it's a rather large patch.
One change I had to make specifically for iOS devices was that debugserver can't
create files. There were several tests that launch the inferior process redirecting
its output to a file, then they retrieve the file. They were not trying to test
file redirection in these tests, so I rewrote those to write their output to a file
directly.

There will be some smaller follow-on patches. The changes to tools/lldb-server are
verbose and I'm not thrilled with having to skip all of these tests manually.
There are a few places where I'm making the assumption that "armv7", "armv7k", "arm64"
means it's an ios device, and I need to review & clean these up with an OS check
as well. (Android will show up as "arm" and "aarch64" so by pure luck they shouldn't
cause problems, but it's not an assumption I want to rely on).
