Raphael Isemann 808142876c [lldb][NFC] Fix all formatting errors in .cpp file headers
Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).

This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Lawrence D'Anna 9efbc564ba build fix for SBInstruction.
oops!  I cherry-picked  rL374820 thinking it was completely
independent of D68737, but it wasn't.  It makes an incidental
use of SBFile::GetFile, which is introduced there, so I broke the
build.

The docs say you can commit without review for "obvious".   I think
this qualifies.   If this kind of fix isn't considered obvious, let
me know and I'll revert instead.

Lawrence D'Anna e7a9115680 remove FILE* bindings from SBInstruction.
Summary:
This patch replaces the FILE* python bindings for SBInstruction and
SBInstructionList and replaces them with the new, safe SBFile and FileSP
bindings.

I also re-enable `Test_Disassemble_VST1_64`, because now we can use
the file bindings as an additional test of the disassembler, and we
can use the disassembler test as a test of the file bindings.

The bugs referred to in the comments appear to have been fixed.   The
radar is closed now and the bugzilla bug does not reproduce with the
instructions given.

Konrad Kleine 248a13057a [lldb] NFC modernize codebase with modernize-use-nullptr
Summary:
NFC = [[ https://llvm.org/docs/Lexicon.html#nfc | Non functional change ]]

This commit is the result of modernizing the LLDB codebase by using
`nullptr` instread of `0` or `NULL`. See
https://clang.llvm.org/extra/clang-tidy/checks/modernize-use-nullptr.html
for more information.

This is the command I ran and I to fix and format the code base:

```
run-clang-tidy.py \
	-header-filter='.*' \
	-checks='-*,modernize-use-nullptr' \
	-fix ~/dev/llvm-project/lldb/.* \
	-format \
	-style LLVM \
	-p ~/llvm-builds/debug-ninja-gcc
```

NOTE: There were also changes to `llvm/utils/unittest` but I did not
include them because I felt that maybe this library shall be updated in
isolation somehow.

NOTE: I know this is a rather large commit but it is a nobrainer in most
parts.

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.

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.

Move SBRegistry method registrations from SBReproducer.cpp into files
declaring the individual APIs, in order to reduce the memory consumption

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.

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.

This is intended as a clean up after the big clang-format commit

FYI, the script I used was:

out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:

  text = ""
  comment = re.compile(r'^( *//) ([^ ].*)$')
  special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$')
  for line in f:
      match = comment.match(line)
      if match and not special.match(match.group(2)):
          # skip intentionally short comments.
          if not text and len(match.group(2)) < 40:
              out.write(line)
              continue

          if text:
              text += " " + match.group(2)
          else:
              header = match.group(1)
              text = match.group(2)

          continue

      if text:
          filled = textwrap.wrap(text, width=(78-len(header)),
                                 break_long_words=False)
          for l in filled:

Pavel Labath 5f19b90783 Move ArchSpec to the Utility module
The rationale here is that ArchSpec is used throughout the codebase,
including in places which should not depend on the rest of the code in
the Core module.

This commit touches many files, but most of it is just renaming of
 #include lines. In a couple of cases, I removed the #include ArchSpec
line altogether, as the file was not using it. In one or two places,
this necessitated adding other #includes like lldb-private-defines.h.

Pavel Labath 7263f1bda6 Invert ArchSpec<->Platform dependency
Summary:
ArchSpec::SetTriple was taking a Platform as an argument, and used it to
fill in missing pieces of the specified triple. I invert the dependency
by moving this code to other classes. For this purpose, I've created
three new functions.
- HostInfo::GetAugmentedArchSpec: fills in the triple using the host
  platform (this used to be implemented by passing a null platform
  pointer). By putting this code in the Host module, we can provide a
  way to anyone who does not have a platform instance (lldb-server) an
  easy way to get Host data.
- Platform::GetAugmentedArchSpec: if you have a platform instance, you
  can call this to let it fill in the triple.
- static Platform::GetAugmentedArchSpec: implements the "if platform ==
  0 then use_host() else use_platform()" part.

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.

Greg Clayton 4a9d83a55e Fix a memory leak in InstructionLLVMC where it held onto a strong reference to the DisassemblerLLVMC which in turn had a vector of InstructionSP causing the strong cycle. This is fixed now.
Rules are as follows for internal code using lldb::DisassemblerSP and lldb::InstructionSP:
1 - The disassembler needs to stay around as long as instructions do as the Instruction subclass now has a weak pointer to the disassembler
2 - The public API has been fixed so that if you get a SBInstruction, it will hold onto a strong reference to the disassembler in a new InstructionImpl class

This will keep code like like: 

inst = lldb.target.ReadInstructions(frame.GetPCAddress(), 1).GetInstructionAtIndex(0)
inst.GetMnemonic()

Working as expected (not the SBInstructionList() that was returned by SBTarget.ReadInstructions() is gone, but "inst" has a strong reference inside of it to the disassembler and the instruction.
                                                     
All code inside the LLDB shared library was verified to correctly hold onto the disassembler instance in all places.

Jason Molenda c980fa92eb Change the default disassembly format again. First attempt at
changing it was in r219544 - after living on that for a few 
months, I wanted to take another crack at this.

The disassembly-format setting still exists and the old format
can be user specified with a setting like

${current-pc-arrow}${addr-file-or-load}{ <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>}:

Greg Clayton 554f68d385 Get rid of Debugger::FormatPrompt() and replace it with the new FormatEntity class.
Why? Debugger::FormatPrompt() would run through the format prompt every time and parse it and emit it piece by piece. It also did formatting differently depending on which key/value pair it was parsing. 

The new code improves on this with the following features:
1 - Allow format strings to be parsed into a FormatEntity::Entry which can contain multiple child FormatEntity::Entry objects. This FormatEntity::Entry is a parsed version of what was previously always done in Debugger::FormatPrompt() so it is more efficient to emit formatted strings using the new parsed FormatEntity::Entry.
2 - Allows errors in format strings to be shown immediately when setting the settings (frame-format, thread-format, disassembly-format
3 - Allows auto completion by implementing a new OptionValueFormatEntity and switching frame-format, thread-format, and disassembly-format settings over to using it.
4 - The FormatEntity::Entry for each of the frame-format, thread-format, disassembly-format settings only replaces the old one if the format parses correctly
5 - Combines all consecutive string values together for efficient output. This means all "${ansi.*}" keys and all desensitized characters like "\n" "\t" "\0721" "\x23" will get combined with their previous strings
6 - ${*.script:} (like "${var.script:mymodule.my_var_function}") have all been switched over to use ${script.*:} "${script.var:mymodule.my_var_function}") to make the format easier to parse as I don't believe anyone was using these format string power user features.
7 - All key values pairs are defined in simple C arrays of entries so it is much easier to add new entries.

These changes pave the way for subsequent modifications where we can modify formats to do more (like control the width of value strings can do more and add more functionality more easily like string formatting to control the width, printf formats and more).
