Lawrence D'Anna 322f12afc3 remove FILE* usage from ReportEventState() and HandleProcessEvent()
Summary:
This patch adds FileSP and SBFile versions of the API methods
ReportEventState and  HandleProcessEvent.   It points the SWIG
wrappers at these instead of the ones that use FILE* streams.

Lawrence D'Anna d5768e3d0e Fix test breakage caused by r374424
Summary:
The build directory name is based on the test method name, so having
two test methods with the same name in the same test file is a
problem, even if they're in different test classes.

On linux and darwin this conflict can go unnoticed, but windows
has different filesystem semantics and it will fail when one
process tries to delete files still held open by another.

The problem is fixed just by changing the name of one of the test
methods.

Pavel Labath 5a8db84964 DWARFExpression: Fix/add support for (v4) debug_loc base address selection entries
The DWARFExpression is parsing the location lists in about five places.
Of those, only one actually had proper support for base address
selection entries.

Since r374600, llvm has started to produce location expressions with
base address selection entries more aggresively, which caused some tests
to fail.

This patch adds support for these entries to the places which had it
missing, fixing the failing tests. It also adds a targeted test for the
two of the three fixes, which should continue testing this functionality
even if the llvm output changes. I am not aware of a way to write a
targeted test for the third fix (DWARFExpression::Evaluate).

Walter Erquinigo af1d27e301 [platform process list] add a flag for showing the processes of all users
Summary:
For context: https://reviews.llvm.org/D68293

We need a way to show all the processes on android regardless of the user id.
When you run `platform process list`, you only see the processes with the same user as the user that launched lldb-server. However, it's quite useful to see all the processes, though, and it will lay a foundation for full apk debugging support from lldb.

Before:
```
PID    PARENT USER       TRIPLE                   NAME
====== ====== ========== ======================== ============================
3234   1                 aarch64-unknown-linux-android adbd

9098   9096              aarch64-unknown-linux-android lldb-server

```

Now:
```

Walter Erquinigo 089a334c39 [platform process list] add a flag for showing the processes of all users
Summary:
For context: https://reviews.llvm.org/D68293

We need a way to show all the processes on android regardless of the user id.
When you run `platform process list`, you only see the processes with the same user as the user that launched lldb-server. However, it's quite useful to see all the processes, though, and it will lay a foundation for full apk debugging support from lldb.

Before:
```
PID    PARENT USER       TRIPLE                   NAME
====== ====== ========== ======================== ============================
3234   1                 aarch64-unknown-linux-android adbd
8034   3234              aarch64-unknown-linux-android sh
9096   3234              aarch64-unknown-linux-android sh
9098   9096              aarch64-unknown-linux-android lldb-server
(lldb) ^D
```

Now:
```
(lldb) platform process list -x
205 matching processes were found on "remote-android"
PID    PARENT USER       TRIPLE                   NAME

Lawrence D'Anna b3faa01ff9 IOHandler: fall back on File::Read if a FILE* isn't available.
Summary:
IOHandler needs to read lines of input from a lldb::File.
The way it currently does this using, FILE*, which is something
we want to avoid now.   I'd prefer to just replace the FILE* code
with calls to File::Read, but it contains an awkward and
delicate workaround specific to ctrl-C handling on windows, and
it's not clear if or how that workaround would translate to
lldb::File.

So in this patch, we use use the FILE* if it's available, and only
fall back on File::Read if that's the only option.

I think this is a reasonable approach here for two reasons.  First
is that interactive terminal support is the one area where FILE*
can't be avoided.   We need them for libedit and curses anyway,
and using them here as well is consistent with that pattern.

The second reason is that the comments express a hope that the
underlying windows bug that's being worked around will be fixed one
day, so hopefully when that happens, that whole path can be deleted.

Pavel Labath a8b18baa0f ProcessInstanceInfoMatch: Don't match processes with no name if a name match was requested, take 2
Summary:
The previous attempt at making nameless process not match when searching for a
given name failed because the macos implementation was depending on this detail
in its partial matching strategy. Doing partial matching to avoid expensive
lookups is a perfectly valid thing to do, the way it was implemented seems
somewhat unexpected.

This patch implements it differently by providing special
methods in the ProcessInstanceInfoMatch which match only a subset of fields,
and changes mac host code to use those instead.

Then, it re-applies r373925 to get make the ProcessInstanceInfoMatch with a
name *not* match a nameless process.

Aleksandr Urakov 30c2441a32 [Windows] Use information from the PE32 exceptions directory to construct unwind plans
This patch adds an implementation of unwinding using PE EH info. It allows to
get almost ideal call stacks on 64-bit Windows systems (except some epilogue
cases, but I believe that they can be fixed with unwind plan disassembly
augmentation in the future).

To achieve the goal the CallFrameInfo abstraction was made. It is based on the
DWARFCallFrameInfo class interface with a few changes to make it less
DWARF-specific.

To implement the new interface for PECOFF object files the class PECallFrameInfo
was written. It uses the next helper classes:

- UnwindCodesIterator helps to iterate through UnwindCode structures (and
  processes chained infos transparently);
- EHProgramBuilder with the use of UnwindCodesIterator constructs EHProgram;
- EHProgram is, by fact, a vector of EHInstructions. It creates an abstraction
  over the low-level unwind codes and simplifies work with them. It contains
  only the information that is relevant to unwinding in the unified form. Also
  the required unwind codes are read from the object file only once with it;
- EHProgramRange allows to take a range of EHProgram and to build an unwind row
  for it.

So, PECallFrameInfo builds the EHProgram with EHProgramBuilder, takes the ranges
corresponding to every offset in prologue and builds the rows of the resulted
unwind plan. The resulted plan covers the whole range of the function except the
epilogue.

Raphael Isemann 423c2e98e4 [lldb] Fix crash in CxxModuleHandler when std module is empty
We currently don't handle the error in the Expected we get
when searching for an equal local DeclContext. Usually this can't
happen as this would require that we have a STL container and
we can find libc++'s std module, but when we load the module in
the expression parser the module doesn't even contain the 'std'
namespace. The only way I see to test this is by having a fake
'std' module that requires a special define to actually provide
its contents, while it will just be empty (that is, it doesn't
even contain the 'std' namespace) without that define. LLDB currently
doesn't know about that define in the expression parser, so it
will load the wrong 'empty' module which should trigger this error.

Also removed the 'auto' for that variable as the function name
doesn't make it obvious that this is an expected and not just
a optional/ptr (which is how this slipped in from the start).

Dimitry Andric a42942e0ec Fix process launch failure on FreeBSD after r365761
Summary:
After rLLDB365761, and with `LLVM_ENABLE_ABI_BREAKING_CHECKS` enabled,
launching any process on FreeBSD crashes lldb with:

```
Expected<T> must be checked before access or destruction.
Expected<T> value was in success state. (Note: Expected<T> values in success mode must still be checked prior to being destroyed).
```

This is because `m_operation_thread` and `m_monitor_thread` were wrapped
in `llvm::Expected<>`, but this requires the objects to be correctly
initialized before accessing them.

To fix the crashes, use `llvm::Optional<>` for the members (as indicated
by labath), and use local variables to store the return values of
`LaunchThread` and `StartMonitoringChildProcess`.  Then, only assign to
the member variables after checking if the return values indicated
success.

Lawrence D'Anna ab1cd65f19 update TestRunCommandInterpreterAPI to use SBFile
Summary:
If you look at what this test is doing, it's actually quite
mysterious why it works at all.   It sets the input file
inside a "with open".   As soon as the with block ends,
that file will be closed.   And yet somehow LLDB reads
commands from it anyway.    What's actually happening is that
the file descriptor gets dup'd when something inside LLDB
calls File::GetStream().   I think it's fair to say that
what this test is doing is illegal and it has no right
to expect it to work.

This patch updates the test with two cases.  One uses
the SBFile api, and actually transfers ownership of
the original file descriptor to the debugger.   The other
just uses the old FILE* API, but in a sane way.

I also set NO_DEBUG_INFO_TESTCASE, because this test doesn't
use any debug info and doesn't need to run three times.
