Pavel Labath f7174ef573 [LLDB] Fix TestTargetXMLArch's expected arch
Summary:
When running on an architecture other than x86_64, the
target.ConnectRemote() part of the test may add platform information to
the target triple.

It was observed that this happens at Process::CompleteAttach() method,
after the platform_sp->IsCompatibleArchitecture() check fails.
This method then calls platform_sp->GetPlatformForArchitecture(), that
on a Linux machine ends up returning a generic Linux platform, that then
ends up getting added to the original target architecture.

Pavel Labath e92ecd3196 Fix some tests for PPC64le architecture
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.

Pavel Labath 16064d354a Re-land: [lldb] Use vFlash commands when writing to target's flash memory regions
The difference between this and the previous patch is that now we use
ELF physical addresses only for loading objects into the target (and the
rest of the module load address logic still uses virtual addresses).

Summary:
When writing an object file over gdb-remote, use the vFlashErase, vFlashWrite, and vFlashDone commands if the write address is in a flash memory region.  A bare metal target may have this kind of setup.

- Update ObjectFileELF to set load addresses using physical addresses.  A typical case may be a data section with a physical address in ROM and a virtual address in RAM, which should be loaded to the ROM address.
- Add support for querying the target's qXfer:memory-map, which contains information about flash memory regions, leveraging MemoryRegionInfo data structures with minor modifications
- Update ProcessGDBRemote to use vFlash commands in DoWriteMemory when the target address is in a flash region

Pavel Labath 63047d05c0 [dotest] Clean up test folder clean-up
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.

Pavel Labath 0428ddd7fc Fix TestProcessLaunch breakage on MacOS
This test started failing after r327625. The cause seems difference in the
treatment of relative --stdin paths between MacOS (debugserver?) and linux
(lldb-server?). Linux treats this as relative to the debuggers PWD, while MacOS
as relative to (I think) the future PWD of the launched process.

This fixes the issue by using absolute paths, which should work everywhere, but
we should probably unify this path handling as well. I'll ask around about what
is the expected behavior here.

Pavel Labath 107052ff9d Next batch of test-tree-cleaning changes
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.

Greg Clayton 9cc222c80d Fix a bug in "target.source-map" where we would resolve unmapped paths incorrectly
When using:

(lldb) settings set target.source-map ./ /path/to/source
LLDB would fail to set a source file and line breakpoint with:

(lldb) breakpoint set --file /path/to/source/main.c --line 2
Because code in the target was undoing the remapping of "/path/to/source/main.c" to "./main.c" and then it would resolve this path, which would append the current working directory to the path. We don't want to resolve paths that we unmap.

Test case added.

After this change, the lldb-mi tests seem to be in better health (on
Darwin at least). I consistently get:

Pavel Labath 5f56fca4e1 Move option parsing out of the Args class
Summary:
The args class is used in plenty of places (a lot of them in the lower lldb
layers) for representing a list of arguments, and most of these places don't
care about option parsing. Moving the option parsing out of the class removes
the largest external dependency (there are a couple more, but these are in
static functions), and brings us closer to being able to move it to the
Utility module).

The new home for these functions is the Options class, which was already used
as an argument to the parse calls, so this just inverts the dependency between
the two.

The functions are themselves are mainly just copied -- the biggest functional
change I've made to them is to avoid modifying the input Args argument (getopt
likes to permute the argument vector), as it was weird to have another class
reorder the entries in Args class. So now the functions don't modify the input
arguments, and (for those where it makes sense) return a new Args vector
instead. I've also made the addition of a "fake arg0" (required for getopt
compatibility) an implementation detail rather than a part of interface.

While doing that I noticed that ParseForCompletion function was recording the
option indexes in the shuffled vector, but then the consumer was looking up the
entries in the unshuffled one. This manifested itself as us not being able to
complete "watchpoint set variable foo --" (because getopt would move "foo" to
the end). Surprisingly all other completions (e.g. "watchpoint set variable foo
--w") were not affected by this. However, I couldn't find a comprehensive test
for command argument completion, so I consolidated the existing tests and added
a bunch of new ones.

Pavel Labath 96979ceecb Rewrite TestTargetSymbolsBuildidCase to be more focused
Summary:
The test was failing in remote debugging scenario with windows as a host
as cmd.exe is not able to parse the complicated shell commands in the
Makefile.

The test seemed like a perfect candidate for a more focused testing
approach, so I have rewritten in on top of lldb-test's module-sections
functionality. The slight gotcha there was that the
Module::GetSectionList does not include the sections from the symbol
file until someone manually calls Module::GetSymbolVendor. Normally,
this is not an issue, because someone will have initialized the symbol
vendor by the time anyone starts looking at the sections. However, when
all one this is dump the section list, we run into this problem.

I've tried making this behavior more automatic, but it turns out it's
not that easy, so for now, I just manually initialize the Symbol Vendor
before dumping out the sections in lldb-test.

Jonas Devlieghere 3a9d431386 [testsuite] Remove workaround for categories and inline tests.
Adding categories to inline tests does not work because the attribute
is set at the function level. For methods, this means it applies to all
instances of that particular class. While this is what we want in most
cases, it's not for inline tests, where different instances correspond
to different tests.

With the workaround in place, assigning a category to one test resulted
in the category applied to *all* inline tests.

This patch removes the workaround and throws an exception with an
informative error message, to prevent this from happening in the future.

Pavel Labath 4c693a894f Speed up TestWatchpointMultipleThreads
Summary:
The inferior was sleeping before doing any interesting work. I remove that
to make the test faster.

While looking at the purpose of the test (to check that watchpoints are
propagated to all existing threads - r140757) I noticed that the test has
diverged from the original intention and now it creates the threads *after* the
watchpoint is set (this probably happened during the std::thread refactor).
After some discussion, we decided both scenarios make sense, so I modify the
test to test both.

The watchpoint propagation functionality is not really debug info depenent, so
I also stop replication of this test. This brings the test's time from ~108s
down to 4s.

Jim Ingham 06292869cd We were getting the wrong dynamic type if there were two classes with the same basename.
There's a bug in FindTypes, it ignores the exact flag if you pass a name that doesn't begin with
:: and pass eTypeClassAny for the type.

In this case we always know that the name we get from the vtable name is absolute so we can
work around the bug by prepending the "::".  This doesn't fix the FindTypes bug.

Pavel Labath 029fb69372 [lldb] Use vFlash commands when writing to target's flash memory regions
Summary:
When writing an object file over gdb-remote, use the vFlashErase, vFlashWrite, and vFlashDone commands if the write address is in a flash memory region.  A bare metal target may have this kind of setup.

- Update ObjectFileELF to set load addresses using physical addresses.  A typical case may be a data section with a physical address in ROM and a virtual address in RAM, which should be loaded to the ROM address.
- Add support for querying the target's qXfer:memory-map, which contains information about flash memory regions, leveraging MemoryRegionInfo data structures with minor modifications
- Update ProcessGDBRemote to use vFlash commands in DoWriteMemory when the target address is in a flash region

Adrian McCarthy 00cc735a6f Partial fix for TestConflictingSymbol.py on Windows
Without this fix, the test ERRORs because the link of the inferior fails. This
patch adds the LLDB_TEST_API macro where needed and uses the new -2 magic
value for num_expected_locations to account for lazy-loading of module symbols
on Windows.

With this fix, the test itself still fails:  conflicting_symbol isn't in the
debug info nor the export table, and Windows binaries don't have an equivalent
of the ELF .symtab.  We need to understand why the test works to keep the
symbol out of the debug info.  In the mean time, having the test fail at this
point is a better indication of the remaining problem than a build error.

Pavel Labath 7c94582f90 Add "lldb-test breakpoint" command and convert the case-sensitivity test to use it
Summary:
The command takes two input arguments: a module to use as a debug target
and a file containing a list of commands. The command will execute each
of the breakpoint commands in the file and dump the breakpoint state
after each one.

The commands are expected to be breakpoint set/remove/etc. commands, but
I explicitly allow any lldb command here, so you can do things like
change setting which impact breakpoint resolution, etc. There is also a
"-persistent" flag, which causes lldb-test to *not* automatically clear
the breakpoint list after each command. Right now I don't use it, but
the idea behind it was that it could be used to test more complex
combinations of breakpoint commands (set+modify, set+disable, etc.).

Right now the command prints out only the basic breakpoint state, but
more information can be easily added there.  To enable easy matching of
the "at least one breakpoint location found" state, the command
explicitly prints out the string "At least one breakpoint location.".

To enable testing of breakpoints set with an absolute paths, I add the
ability to perform rudimentary substitutions on the commands: right now
the string %p is replaced by the directory which contains the command
file (so, under normal circumstances, this will perform the same
substitution as lit would do for %p).

I use this command to rewrite the TestBreakpointCaseSensitivity test --
the test was checking about a dozen breakpoint commands, but it was
launching a new process for each one, so it took about 90 seconds to
run. The new test takes about 0.3 seconds for me, which is approximately
a 300x speedup.

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).

Pavel Labath a9f8b0d1a9 Avoid dirtying the source tree in breakpoint command tests
Summary:
The paralelization patch exposed a bunch of cases where we were still
touching the source tree (as these tests were now stepping on each
others toes and being flaky).

This patch removes such issues from breakpoint command tests. Since the
only reason they were creating files was to indirectly test whether the
breakpoint commands got executed (and plumbing the full build tree path
to all places that needed it would be messy) I decided to modify the
tests to check for a different side effect instead: modification of a
global variable. This also makes the code simpler as checking the value
of the global variable is easier, and there is nothing to clean up.

As the tests aren't really doing anything debug-info related, I took the
opportunity to also mark them as NO_DEBUG_INFO_TESTCASEs.

The first issue is about the flaky test rerun logic. This was grouping

The second problem (which I noticed while investigating the first one)
was that the "-p" switch was not working in multiprocessing mode. This
happened because we were returning None from process_file instead of a
tuple full of empty values for tests that did not match the -p regex.

Both of these would be caught earlier if python was a more strongly

Pavel Labath 42a1619262 [dosep] Run tests in a more parallel fashion
Summary:
Due to in-tree builds, we were parallelizing the tests at the directory
level. Now that the tests are built out-of-tree, we can remove this
limitation and paralelize at file level instead.

This decreases test suite time by about 10% for me, which is not
world-shattering, but it makes the code slightly simpler and will also
allow us to merge tests which were artificially spread over multiple
folders (TestConcurrentEvents...) to work-around this limitation.

To make this work, I've also needed to include the test file name in the
build directory name, as just the test method name is not unique enough
(plenty of tests have a test method called "test" or similar).

While doing this, I've found a couple of tests that are taking waaay longer then
they ought to (TestBreakpointCaseSensitivity -- 90 seconds), which I plan to
look into in the future.

Pavel Labath 014e4654d4 Rewrite the flaky test_restart_bug test in a more deterministic way
Summary:
The test was trying to reproduce a bug in handling of two concurrent
events, which was impossible to do reliably in a black-box style test.
In practice, this meant the test was only ever failing on remote
targets, as these were slow enough to trigger this.

Fortunately, we now have the ability to mock the server side of the
connection, which means we can simulate the failure deterministically,
so I rewrite the test to use the new gdb-client framework.

I've needed to add a couple of new packets to the mock server to be able
to do this. Instead of trying to guess how a "typical" gdb-client test
will want to handle this, I throw an exception in the implementation to
force the user to override them (the packets are only sent if the test
explicitly performs some action which will trigger them, so a basic test
which e.g. does not need the "continue" functionality will not need to
implement them).

Tests that are marked as NO_DEBUG_INFO_TESTCASE and build with
buildDefault() are built in a <test>.default build directory.

Pavel Labath 55790fb7f8 [dotest] make debug info variant accessible in setUp()
Summary:
This changes the way we store the debug info variant to make it
available earlier in the test bringup: instead of it being set by the
test wrapper method, it is set as a *property* of the wrapper method.

This way, we can inspect it as soon as self.testMethodName is
initialized. The retrieval is implemented by a new function
TestBase.getDebugInfo(), and all that's necessary to make it work is to
change self.debug_info into self.getDebugInfo().

While searching for debug_info occurences i noticed that TestLogging is
being replicated for no good reason, so I removed the replication there.

Jan Kratochvil 401df58064 Resolve binary symlinks before finding its separate .debug file
I have found LLDB cannot find separate debug info of Fedora /usr/bin/gdb.
It is because:

lrwxrwxrwx 1 root root       14 Jan 25 20:41 /usr/bin/gdb -> ../libexec/gdb*
-rwxr-xr-x 1 root root 10180296 Jan 25 20:41 /usr/libexec/gdb*
ls: cannot access '/usr/lib/debug/usr/bin/gdb-8.0.1-35.fc27.x86_64.debug': No such file or directory
-r--r--r-- 1 root root 29200464 Jan 25 20:41 /usr/lib/debug/usr/libexec/gdb-8.0.1-35.fc27.x86_64.debug

FYI that -8.0.1-35.fc27.x86_64.debug may look confusing, it was always just
.debug before.
Why is /usr/bin/gdb a symlink is offtopic for this bugreport, Fedora has it so
for some reasons.

It is always safest to look at the .debug file only after resolving all
symlinks on the binary file.

Pavel Labath 71ad71e530 mock_gdb_server: rectify ack handling code
The mock server was sending acks back in response to spurious acks from
the client, but the client was not prepared to handle these. Most of the
time this would work because the only time the client was sending
unsolicited acks is after the initial connection, and there reply-ack
would get ignored in the "flush all packets from the server" loop which
came after the ack. However, this loop had only a 10ms delay, and
sometimes this was not enough to catch the reply (which meant the
connection got out of sync, and test failed).

Since this behavior not consistent with how lldb-server handles this
situation (it just ignores the ack), I fix the mock server to do the
same.

Adrian Prantl 5ec76fe720 Compile the LLDB tests out-of-tree.
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.

Stale global module caches cause problems for the bots. The modules

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.

C++ virtual method calls in LLDB expressions may fail if the override table for
the method being called is not correct as IRGen will produce references to the
wrong (or a missing) vtable entry.

This patch does not fix calls to virtual methods with covariant return types as
it mistakenly treats these as overloads, rather than overrides. This will be
