Jonas Devlieghere 63e5fb76ec [Logging] Replace Log::Printf with LLDB_LOG macro (NFC)
This patch replaces explicit calls to log::Printf with the new LLDB_LOGF
macro. The macro is similar to LLDB_LOG but supports printf-style format
strings, instead of formatv-style format strings.

So instead of writing:

  if (log)
    log->Printf("%s\n", str);

You'd write:

  LLDB_LOG(log, "%s\n", str);

This change was done mechanically with the command below. I replaced the
spurious if-checks with vim, since I know how to do multi-line
replacements with it.

  find . -type f -name '*.cpp' -exec \
  sed -i '' -E 's/log->Printf\(/LLDB_LOGF\(log, /g' "{}" +

Jonas Devlieghere c470ac50a8 [Reproducers] Make reproducer relocatable
Before this patch, reproducers weren't relocatable. The reproducer
contained hard coded paths in the VFS mapping, as well in the yaml file
listing the different input files for the command interpreter. This
patch changes that:

 - Use relative paths for the DataCollector.
 - Use an overlay prefix for the FileCollector.

Jonas Devlieghere ef96e985fc [Reproducers] Simplify providers with nested Info struct (NFC)
This replaces the `info` typedef with a nested struct named Info. This
means we now have FooProvider and FooProvider::Info, instead of two
related but separate classes FooProvider and FooInfo. This change is
mostly cosmetic.

Jonas Devlieghere 306809f292 [Reproducers] Capture return values of functions returning by ptr/ref
For some reason I had convinced myself that functions returning by
pointer or reference do not require recording their result. However,
after further considering I don't see how that could work, at least not
with the current implementation. Interestingly enough, the reproducer
instrumentation already (mostly) accounts for this, though the
lldb-instr tool did not.

This patch adds the missing macros and updates the lldb-instr tool.

Michal Gorny ae211ece6a [lldb] [Reproducer] Move SBRegistry registration into declaring files
Move SBRegistry method registrations from SBReproducer.cpp into files
declaring the individual APIs, in order to reduce the memory consumption
during build and improve maintainability.  The current humongous
SBRegistry constructor exhausts all memory on a NetBSD system with 4G
RAM + 4G swap, therefore making it impossible to build LLDB.

Jonas Devlieghere 7bc8356435 [Reproducers] Implement log_append for function pointers.
Changing the type in the DUMMY macro to void* doesn't actually fix the
build error, because the argument type is deducted from the template (as
opposed to when serializing through the instrumentation framework, where
this would matter). Instead I've added a proper instance of log_append
that takes function pointers and logs their address.

Pavel Labath 7f5237bccc Add "operator bool" to SB APIs
Summary:
Our python version of the SB API has (the python equivalent of)
operator bool, but the C++ version doesn't.

This is because our python operators are added by modify-python-lldb.py,
which performs postprocessing on the swig-generated interface files.

In this patch, I add the "operator bool" to all SB classes which have an
IsValid method (which is the same logic used by modify-python-lldb.py).
This way, we make the two interfaces more constent, and it allows us to
rely on swig's automatic syntesis of python __nonzero__ methods instead
of doing manual fixups.

Jonas Devlieghere 581af8b09d [SBAPI] Log from record macro
The current record macros already log the function being called. This
patch extends the macros to also log their input arguments and removes
explicit logging from the SB API.

This might degrade the amount of information in some cases (because of
smarter casts or efforts to log return values). However I think this is
outweighed by the increased coverage and consistency. Furthermore, using
the reproducer infrastructure, diagnosing bugs in the API layer should
become much easier compared to relying on log messages.

Jonas Devlieghere d77c2e0926 [Reproducers] Capture and replay interpreter commands.
This patch adds the necessary logic to capture and replay commands
entered into the command interpreter. A DataRecorder shadows the input
and writes its data to a know file. During replay this file is used as
the command interpreter's input.

It's possible to the command interpreter more than once, with a
different input source. We support this scenario by using multiple
buffers. The synchronization for this takes place at the SB layer, where
we create a new recorder every time the debugger input is changed.
During replay we use the corresponding buffer as input.

As per the discussion on the mailing list:
http://lists.llvm.org/pipermail/lldb-commits/Week-of-Mon-20190218/048007.html

This commit implements option (3):

> Go back to initializing the reproducer before the rest of the debugger.
> The method wouldn't be instrumented and guarantee no other SB methods are
> called or SB objects are constructed. The initialization then becomes part
> of the replay.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
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.

Jonas Devlieghere 15eacd741f [Reproducers] Change how reproducers are initialized.
This patch changes the way the reproducer is initialized. Rather than
making changes at run time we now do everything at initialization time.
To make this happen we had to introduce initializer options and their SB
variant. This allows us to tell the initializer that we're running in
reproducer capture/replay mode.

Because of this change we also had to alter our testing strategy. We
cannot reinitialize LLDB when using the dotest infrastructure. Instead
we use lit and invoke two instances of the driver.

Another consequence is that we can no longer enable capture or replay
through commands. This was bound to go away form the beginning, but I
had something in mind where you could enable/disable specific providers.
However this seems like it adds very little value right now so the
corresponding commands were removed.

Finally this change also means you now have to control this through the
driver, for which I replaced --reproducer with --capture and --replay to
differentiate between the two modes.

Jonas Devlieghere 68ed93d252 [Reproducers] Improve reproducer API and add unit tests.
When I landed the initial reproducer framework I knew there were some
things that needed improvement. Rather than bundling it with a patch
that adds more functionality I split it off into this patch. I also
think the API is stable enough to add unit testing, which is included in
this patch as well.

Other improvements include:

 - Refactor how we initialize the loader and generator.
 - Improve naming consistency: capture and replay seems the least ambiguous.
 - Index providers by name and make sure there's only one of each.
 - Add convenience methods for creating and accessing providers.

Pavel Labath abc0c6ad09 Skip core file tests on build configurations lacking necessary components
Summary:
To successfully open a core file, we need to have LLVM built with
support for the relevant target. Right now, if one does not have the
appropriate targets configured, the tests will fail.

This patch uses the GetBuildConfiguration SB API to inform the test (and
anyone else who cares) about the list of supported LLVM targets. The
test then uses this information to approriately skip the tests.

Alex Langford d17cd90268 Move SystemInitializerFull header to source/API
Summary:
It seems to me that files in include/lldb/API/ are headers that should
be exposed to liblldb users. Because SystemInitializerFull.h exposes details of
lldb_private, I think having it there is not the right thing to do. Since it's
only included from files in source/API, we should move it there and treat it as
private.
