Pavel Labath d821c997aa Move RegisterValue,Scalar,State from Core to Utility
These three classes have no external dependencies, but they are used
from various low-level APIs. Moving them down to Utility improves
overall code layering (although it still does not break any particular
dependency completely).

The XCode project will need to be updated after this change.

Adrian Prantl 05097246f3 Reflow paragraphs in comments.
This is intended as a clean up after the big clang-format commit
(r280751), which unfortunately resulted in many of the comment
paragraphs in LLDB being very hard to read.

FYI, the script I used was:

import textwrap
import commands
import os
import sys
import re
tmp = "%s.tmp"%sys.argv[1]
out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:
  header = ""
  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:
              out.write(header+" "+l+'\n')
              text = ""

      out.write(line)

Zachary Turner 97206d5727 Rename Error -> Status.
This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.

A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error".  Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around.  Hopefully nothing too
serious.

Kamil Rytarowski c5f28e2a05 Switch std::call_once to llvm::call_once
Summary:
The std::call_once implementation in libstdc++ has problems on few systems: NetBSD, OpenBSD and Linux PPC. LLVM ships with a homegrown implementation llvm::call_once to help on these platforms.

This change is required in the NetBSD LLDB port. std::call_once with libstdc++ results with crashing the debugger.

Zachary Turner c156427ded Don't allow direct access to StreamString's internal buffer.
This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.

Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

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.

This change removes the reference from the base class.  Instead, it

Saleem Abdulrasool 2d6a9ec935 Clean up vestigial remnants of locking primitives
This finally removes the use of the Mutex and Condition classes. This is an
intricate patch as the Mutex and Condition classes were tied together.
Furthermore, many places had slightly differing uses of time values. Convert
timeout values to relative everywhere to permit the use of
std::chrono::duration, which is required for the use of
std::condition_variable's timeout. Adjust all Condition and related Mutex
classes over to std::{,recursive_}mutex and std::condition_variable.

This change primarily comes at the cost of breaking the TracingMutex which was
based around the Mutex class. It would be possible to write a wrapper to
provide similar functionality, but that is beyond the scope of this change.

Summary:
Since this is within the lldb namespace, the compiler tries to
export a symbol for it. Unfortunately, since it is inlined, the
symbol is hidden and this results in a mess of warnings when
building on OS X with cmake.

Moving it to the lldb_private namespace eliminates that problem.

Jason Molenda 8825c5c9b4 Re-commit the (fixed) changes from r248985 which were reverted by Pavel
when they introduced android testsuite regressions.  Pavel has run the
testsuite against the updated patch and it completes cleanly now.

The original commit message:


Fixing a subtle issue on Mac OS X systems with dSYMs (possibly
introduced by r235737 but I didn't look into it too closely).

A dSYM can have a per-UUID plist in it which tells lldb where
to find an executable binary for the dSYM (DBGSymbolRichExecutable)
- other information can be included in this plist, like how to
remap the source file paths from their build pathnames to their
long-term storage pathnames.

This per-UUID plist is a unusual; it is used probably exclusively
inside apple with our build system.  It is not created by default
in normal dSYMs.

The problem was like this:

  1. lldb wants to find an executable, given only a UUID
     (this happens when lldb is doing cross-host debugging
      and doesn't have a copy of the target system's binaries)

  2. It eventually calls LocateMacOSXFilesUsingDebugSymbols
     which does a spotlight search for the dSYM on the local
     system, and failing that, tries the DBGShellCommands
     command to find the dSYM.

  3. It gets a dSYM.  It reads the per-UUID plist in the dSYM.
     The dSYM has a DBGSymbolRichExecutable kv pair pointing to
     the binary on a network filesystem.

  4. Using the binary on the network filesystem, lldb now goes
     to find the dSYM.

  5. It starts by looking for a dSYM next to the binary it found.

  6. lldb is now reading the dSYM over a network filesystem,
     ignoring the one it found on its local filesystem earlier.

Everything still *works* but it's much slower.

This would be a tricky one to write up in a testsuite case;
you really need the binary to not exist on the local system.
And LocateMacOSXFilesUsingDebugSymbols will only compile on
Mac OS X - even if I found a way to write up a test case, it
would not run anywhere but on a mac.

One change Greg wanted while I was touching this code was to
have LocateMacOSXFilesUsingDebugSymbols (which could be asked
to find a binary OR find a dSYM) to instead return a ModuleSpec
with the sum total of everything it could find.  This
change of passing around a ModuleSpec instead of a FileSpec
was percolated up into ModuleList::GetSharedModule.

The changes to LocateMacOSXFilesUsingDebugSymbols look larger
than they really are - there's a lot of simple whitespace changes
in there.

I ran the testsuites on mac, no new regressions introduced
