A typo in the patch (using syntax instead of m_syntax) resulted in the
normalization not working properly for windows filespecs when the syntax
was passed as host-native. This did not affect the unit tests, as all of
those pass an explicity syntax, but failed gloriously when running the
full test suite.
I also fix an expectation in an lldb-mi test, which was now failing
because it was expecting a path to be echoed verbatim, but we were now
normalizing it.
As a drive-by, this also fixes the default-in-fully-covered-switch
warning and removes an unused argument from the NeedsNormalization
function.

LLDB doesn't use this packet so we never hit this, but it looks like
some other projects talk to debugserver and are hitting an assert
(https://github.com/derekparker/delve/issues/1015).
We had an off by 1 in the accounting of the FPU structure sizes.
I added a test that basically just check that 'g' doesn't return
an error (currently it assert in debug builds). I didn't make
it an lldb-server test because it looks like lldb-server doesn't
implement the g packet.

When I merged the 2 codepaths that return an OS type, I hade
checked that the places accepting 'iphoneos' would also accept
'ios', but then I got it backwards and return 'iphoneos'.
We use this value to build triples, and there 'iphoneos' is
invalid.
This also makes the test slightly simpler.

Summary:
In one of the 2 places the LC_BUILD_VERSION load command is handled, there
is a bug preventing us from actually handling them (the address where to
read the load command was not updated). This patch factors reading the
deployment target load commands into a helper and adds testing for the 2
code paths calling the helper.
The testing is a little bit complicated because the only times those load
commands matter is when debugging a simulator process. I added a new
decorator to check that a specific SDK is available. The actual testing was
fairly easy once I knew how to run a simulated process.

Summary:
- Fix test jump for powerpc64le
Jumping directly to the return line on power architecture dos not means
returning the value that is seen on the code. The last test fails, because
it needs the execution of some assembly in the beginning of the function.
Avoiding this test for this architecture.
- Avoid evaluate environ variable name on Linux
On Linux the Symbol environ conflicts with another variable, then in
order to avoid it, this test was moved into a specific test, which is not
supported if the OS is Linux.
- Added PPC64le as MIPS behavior
Checking the disassembler output, on PPC64le machines behaves as MPIS.
Added method to identify PPC64le architecture and checking it when
disassembling instructions in the test case.

Patch by Leonardo Bianconi <leonardo.bianconi@eldorado.org.br>.
llvm-svn: 327977
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.

Summary:
The changes here fall into several categories.
- some tests were redirecting inferior stdout/err to a file. For these I
make sure we use an absolute path for the file. I also create a
lldbutil.read_file_on_target helper function to encapsulate the
differences between reading a file locally and remotely.
- some tests were redirecting the pexpect I/O into a file. For these I
use a python StringIO object to avoid creating a file altogether.
- the TestSettings inferior was creating a file. Here, I make sure the
inferior is launched with pwd=build-dir so that the files end up
created there.
- lldb-mi --log (used by some tests) creates a log file in PWD without
the ability say differently. To make this work I make sure to run
lldb-mi with PWD=build_dir. This in turn necessitated a couple of
changes in other lldb-mi tests, which were using relative paths to
access the source tree.

This is a first pass at removing some lldb-mi tests which have been
xfailed and unmaintained for a while. We have open PRs for most of these
tests already. I've opened up the following additional PRs:
llvm.org/PR36739 - lldb-mi driver exits properly
llvm.org/PR36740 - lldb-mi -gdb-set and -gdb-show
llvm.org/PR36741 - lldb-mi -symbol-xxx
The motivation here is to address timeout and pexpect-related issues in
the test suite. This was discussed on lldb-dev in the thread: "increase
timeout for tests?".
After this change, the lldb-mi tests seem to be in better health (on
Darwin at least). I consistently get:

Summary:
On PPC64, the tested functions were being entered through their local entry point, while the tests expected the program to stop at the function start address, that, for PPC64, corresponds to the global entry point.
To fix the issue, the test program was modified to call the functions to be tested through function pointers, which, on PPC64, force the calls through the global entry point, while not affecting the test on other platforms.

This test contained a copy of the inferior used by most of llgs test.
This was done to enable better paralelization, but now it's irrelevant.
llvm-svn: 326218
Summary:
These were not being flaky, but they're still making the tree dirty.
These tests were using lldbutil.append_to_process_working_directory to
derive the file path so I fix them by modifying the function to return
the build directory for local tests.
Technically, now the path returned by this function does not point to
the process working directory for local tests, but I think it makes
sense to keep the function name, as I think we should move towards
launching the process in the build directory (and I intend to change
this for the handful of inferiors that actually care about their PWD,
for example because they need to create files there).

The test was generating long unix socket names, and the addition of a
new folder in the previous patch pushed it over the limit (although
linux has a fairly generous limit for path names, this does not apply to
unix sockets).
Modify the test to use a shorter name instead.

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.

Summary:
This mechanism was mostly redundant with the file-based .categories
mechanism, and it was interfering with it, as any test which implemented
a getCategories method would not inherit the filesystem categories.
This patch removes it. The existing categories are preserved either by

Since the ipv6 patch, we've experienced occasional flakyness in
lldb-server tests. This was due to the fact that lldb-server was trying
to listen on both v4 and v6 localhost sockets (and consider it a success
if at least one of them succeeded), while the test framework was only
trying to connect to the v4 one.
This change makes sure lldb-server only listens on the v4 socket.

Normal customer devices won't be able to run these tests, we're hoping to get

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

file redirection in these tests, so I rewrote those to write their output to a file

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).

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).
