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.

Pavel Labath 4bc0500635 Make operator==s consistent between c++ and python APIs
Summary:
modify-python-lldb.py had code to insert python equality operators to
some classes. Some of those classes already had c++ equality operators,
and some didn't.

This makes the situation more consistent, by removing all equality
handilng from modify-python-lldb. Instead, I add c++ operators to
classes where they were missing, and expose them in the swig interface
files so that they are available to python too.

The only tricky case was the SBAddress class, which had an operator==
defined as a free function, which is not handled by swig. This function
cannot be removed without breaking ABI, and we cannot add an extra
operator== member, as that would make equality comparisons ambiguous.
For this class, I define a python __eq__ function by hand and have it
delegate to the operator!=, which I have defined as a member function.

This isn't fully NFC, as the semantics of some equality functions in
python changes slightly, but I believe it changes for the better (e.g.,
previously SBBreakpoint.__eq__ would consider two breakpoints with the
same ID as equal, even if they belonged to different targets; now they
are only equal if they belong to the same target).

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.

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.

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.

Zachary Turner bf9a77305f Move classes from Core -> Utility.
This moves the following classes from Core -> Utility.

ConstString
Error
RegularExpression
Stream
StreamString

The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes.  So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

Jim Ingham c76c3f2f91 Fix SBWatchpoint::SetEnabled to send an event.
We really shouldn't be sending events for SB API's, dunno when we started
doing that.  We don't do it for other things.  But first restore the status quo.

Jim Ingham 306b62b4ae Switch SBWatchpoint::SetEnabled over to using Process::{Enable,Disable}Watchpoint.
We don't have a good story for what happens to watchpoints when you don't
have a process, or if your process exits.  Clearing that up will instruct 
how to fix this for real.

Also added a test to make sure disable->enable works as well.
This resolves llvm.org/pr30789.

Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

Johnny Chen b90827e66c rdar://problem/11584012
Refactorings of watchpoint creation APIs so that SBTarget::WatchAddress(), SBValue::Watch(), and SBValue::WatchPointee()
now take an additional 'SBError &error' parameter (at the end) to contain the reason if there is some failure in the
operation.  Update 'watchpoint set variable/expression' commands to take advantage of that.

Update existing test cases to reflect the API change and add test cases to verify that the SBError mechanism works for
SBTarget::WatchAddress() by passing an invalid watch_size.

Greg Clayton 81e871ed76 Convert all python objects in our API to use overload the __str__ method
instead of the __repr__. __repr__ is a function that should return an
expression that can be used to recreate an python object and we were using
it to just return a human readable string.

Fixed a crasher when using the new implementation of SBValue::Cast(SBType).

Thread hardened lldb::SBValue and lldb::SBWatchpoint and did other general
improvements to the API.

Fixed a crasher in lldb::SBValue::GetChildMemberWithName() where we didn't
correctly handle not having a target.

Johnny Chen 16dcf718d3 Add a commnad to set a condition for a watchpoint. Example:
watchpoint modify -c 'global==5'

modifies the last created watchpoint so that the condition expression
is evaluated at the stop point to decide whether we should proceed with
the stopping.

Also add SBWatchpont::SetCondition(const char *condition) to set condition
programmatically.

Test cases to come later.

Johnny Chen 01a678603a SBValue::Watch() and SBValue::WatchPointee() are now the official API for creating
a watchpoint for either the variable encapsulated by SBValue (Watch) or the pointee
encapsulated by SBValue (WatchPointee).

Removed SBFrame::WatchValue() and SBFrame::WatchLocation() API as a result of that.

Modified the watchpoint related test suite to reflect the change.

Plus replacing WatchpointLocation with Watchpoint throughout the code base.

There are still cleanups to be dome.  This patch passes the whole test suite.
Check it in so that we aggressively catch regressions.
