Jonas Devlieghere 8b3af63b89 [NFC] Remove ASCII lines from comments
A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.

Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.

I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

Zachary Turner 80552918a9 Move Host/Symbols.cpp to Symbols/LocateSymbolFile.cpp
Given that we have a target named Symbols, one wonders why a
file named Symbols.cpp is not in this target.  To be clear,
the functions exposed from this file are really focused on
*locating* a symbol file on a given host, which is where the
ambiguity comes in.  However, it makes more sense conceptually
to be in the Symbols target. While some of the specific places
to search for symbol files might change depending on the Host,
this is not inherently true in the same way that, for example,
"accessing the file system" or "starting threads" is
fundamentally dependent on the Host.

PDBs, for example, recently became a reality on non-Windows platforms,
and it's theoretically possible that DSYMs could become a thing on non
MacOSX platforms (maybe in a remote debugging scenario). Other types of
symbol files, such as DWO, DWP, etc have never been tied to any Host
platform anyway.

After this patch, there is only one remaining dependency from
Host to Target.

Jonas Devlieghere d5b440369d Replace 'ap' with 'up' suffix in variable names. (NFC)
The `ap` suffix is a remnant of lldb's former use of auto pointers,
before they got deprecated. Although all their uses were replaced by
unique pointers, some variables still carried the suffix.

In r353795 I removed another auto_ptr remnant, namely redundant calls to
::get for unique_pointers. Jim justly noted that this is a good
opportunity to clean up the variable names as well.

I went over all the changes to ensure my find-and-replace didn't have
any undesired side-effects. I hope I didn't miss any, but if you end up
at this commit doing a git blame on a weirdly named variable, please
know that the change was unintentional.

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.

Pavel Labath 181b823b04 Move Broadcaster+Listener+Event combo from Core into Utility
Summary:
These are general purpose "utility" classes, whose functionality is not
debugger-specific in any way. As such, I believe they belong in the
Utility module.

This doesn't break any particular dependency (yet), but it reduces the
number of Core dependencies across the board.

This is an NFC commit to refactor the "load dependent files" parameter
from a boolean to an enum value. We want to be able to specify a

dylib).

Pavel Labath 7704473172 Move SafeMachO from Utility to Host
Summary:
One of the conclusions of the discussion on D49740 was that SafeMachO is better
off in the Host module (as that's the only place which should include
mach/machine.h, which is what this header is working around). Also, Utility,
which is the only module which cannot include Host, should not be doing
anything with object file formats.

This patch implements that move, and also removes any unneded includes of that
file.

I've verified that MacOS still compiles after this.

Raphael Isemann 7fae4932ad Move Predicate.h from Host to Utility
Summary:
This class was initially in Host because its implementation used to be
very OS-specific. However, with C++11, it has become a very simple
std::condition_variable wrapper, with no host-specific code.

It is also a general purpose utility class, so it makes sense for it to
live in a place where it can be used by everyone.

This has no effect on the layering right now, but it enables me to later
move the Listener+Broadcaster+Event combo to a lower layer, which is
important, as these are used in a lot of places (notably for launching a
process in Host code).

Stella Stamenova 45d8134c3b [windows] LLDB shows the wrong values when register read is executed at a frame other than zero
Summary:
This is a clean version of the change suggested here: https://bugs.llvm.org/show_bug.cgi?id=37495

The main change is to follow the same pattern as non-windows targets and use an unwinder object to retrieve the register context. I also changed a couple of the comments to actually log, so that issues with unsupported scenarios can be tracked down more easily. Lastly, ClearStackFrames is implemented in the base class, so individual thread implementations don't have to override it.

      if match and not special.match(match.group(2)):
          # skip intentionally short comments.
          if not text and len(match.group(2)) < 40:

A change of this magnitude cannot easily be done without

some lingering occurences left around.  Hopefully nothing too

This moves the following classes from Core -> Utility.

Stream

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.
