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' "{}" +

Greg Clayton 5f8e88cd69 Fix bug in ArchSpec::MergeFrom
Previous ArchSpec tests didn't catch this bug since we never tested just the OS being out of date. Fixed the bug and covered this with a test that would catch this.

This was found when trying to load a core file where the core file was an ELF file with just the e_machine for architeture and where the ELF header had no OS set in the OSABI field of the e_ident. It wasn't merging the architecture with the target architecture correctly.

Adrian Prantl 0e4c482124 Pass ConstString by value (NFC)
My apologies for the large patch. With the exception of ConstString.h
itself it was entirely produced by sed.

ConstString has exactly one const char * data member, so passing a
ConstString by reference is not any more efficient than copying it by
value. In both cases a single pointer is passed. But passing it by
value makes it harder to accidentally return the address of a local
object.

(This fixes rdar://problem/48640859 for the Apple folks)

Alex Langford 6d6288ae97 [Utility] Fix ArchSpec.MergeFrom to correctly merge environments
Summary:
This behavior was originally added in rL252264 (git commit 76a7f365da)
in order to be extra careful with handling platforms like watchos and tvos.
However, as far as triples go, those two (and others) are treated as OSes and
not environments, so that should not really apply here.

Additionally, this behavior is incorrect and can lead to incorrect ArchSpecs.
Because android is specified as an environment and not an OS, not propogating
the environment can lead to modules and targets being misidentified.

Alex Langford bee015efb5 [Utility] Remove Triple{Environment,OS,Vendor}IsUnspecifiedUnknown from ArchSpec
Summary:
These functions should always return the opposite of the
`Triple{Environment,OS,Vendor}WasSpecified` functions. Unspecified unknown is
the same as unspecified, which is why one set of functions should give us what
we want. It's possible to have specified unknown, which is why we can't just
rely on checking the enum values of vendor/os/environment. We must also ensure
that the names of these are empty and not "unknown".

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.

Adrian Prantl 10deee997d Fix a bug PlatformDarwin::SDKSupportsModule.
This fixes a bug PlatformDarwin::SDKSupportsModule introduced by
https://reviews.llvm.org/D47889.  VersionTuple::tryParse() can deal
with an optional third (micro) component, but the parse will fail when
there are extra characters after the version number (e.g.: trying to
parse the substring "12.0.sdk" out of "iPhoneSimulator12.0.sdk" fails
after that patch).  Fixed here by stripping the ".sdk" suffix first.

Raphael Isemann 1a6d7ab55d Narrow the CompletionRequest API to being append-only.
Summary:
We currently allow any completion handler to read and manipulate the list of matches we
calculated so far. This leads to a few problems:

Firstly, a completion handler's logic can now depend on previously calculated results
by another handlers. No completion handler should have such an implicit dependency,
but the current API makes it likely that this could happen (or already happens). Especially
the fact that some completion handler deleted all previously calculated results can mess
things up right now.

Secondly, all completion handlers have knowledge about our internal data structures with
this API. This makes refactoring this internal data structure much harder than it should be.
Especially planned changes like the support of descriptions for completions are currently
giant patches because we have to refactor every single completion handler.

This patch narrows the contract the CompletionRequest has with the different handlers to:

1. A handler can suggest a completion.
2. A handler can ask how many suggestions we already have.

Point 2 obviously means we still have a  dependency left between the different handlers, but
getting rid of this is too large to just append it to this patch.

Otherwise this patch just completely hides the internal StringList to the different handlers.

The CompletionRequest API now also ensures that the list of completions is unique and we
don't suggest the same value multiple times to the user. This property has been so far only
been ensured by the `Option` handler, but is now applied globally. This is part of this patch
as the OptionHandler is no longer able to implement this functionality itself.

Raphael Isemann a2e76c0bfc Replaced more boilerplate code with CompletionRequest (NFC)
Summary:
As suggested in D48796, this patch replaces even more internal calls that were using the old
completion API style with a single CompletionRequest. In some cases we also pass an option
vector/index, but as we don't always have this information, it currently is not part of the
CompletionRequest class.

The constructor of the CompletionRequest is now also more sensible. You only pass the
user input, cursor position and your list of matches to the request and the rest will be
inferred (using the same code we used before to calculate this). You also have to pass these
match window parameters to it, even though they are unused right now.

The patch shouldn't change any behavior.

Adrian Prantl 05097246f3 Reflow paragraphs in comments.
This is intended as a clean up after the big clang-format commit

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)

Pavel Labath 36e82208c7 Remove ObjectFile usage from HostLinux::GetProcessInfo
Summary:
The ObjectFile class was used to determine the architecture of a running
process by inspecting it's main executable. There were two issues with
this:
- it's in the wrong layer
- the call can be very expensive (it can end up computing the crc of the
  whole file).

Since the process is running on the host, ideally we would be able to
just query the data straight from the OS like darwin does, but there
doesn't seem to be a reasonable way to do that. So, this fixes the
layering issue by using the llvm object library to inspect the file.
Since we know the process is already running on the host, we just need
to peek at a few bytes of the elf header to determine whether it's 32-
or 64-bit (which should make this faster as well).

Pretty much the same logic was implemented in
NativeProcessProtocol::ResolveProcessArchitecture, so I delete this
logic and replace calls with GetProcessInfo.

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.
