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.

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 patch removes the comments following the header includes. They were
added after running IWYU over the LLDB codebase. However they add little
value, are often outdates and burdensome to maintain.

Kamil Rytarowski b5bc933c29 Do not pass non-POD type variables through variadic function
Summary:
Cannot pass object of non-POD type 'const CMIUtilString' through variadic function.

This behavior is undefined according to C++11 5.2.2/7:

> Passing a potentially-evaluated argument of class type having a non-trivial copy constructor, a non-trivial move contructor, or a non-trivial destructor, with no corresponding parameter, is conditionally-supported with implementation-defined semantics.

Replace SetErrorDescriptionn(errMsg); with SetErrorDescription(errMsg);

Pavel Labath 7a6252158e Clean up some use of __ANDROID_NDK__ in the cmake files
Rationale:
scripts/Python/modules: android is excluded at a higher level, so no point in
  checking here
tools/lldb-mi: lldb-mi builds fine (with some cosmetic tweaks) on android, and
  there is no reason it shouldn't.
tools/lldb-server: LLDB_DISABLE_LIBEDIT/CURSES already take the platform into
  account, so there is no point in checking again.

I am reasonably confident this should not break the build on any platform, but
I'll keep an eye out on the bots.

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.

Ilia K b2b0170c0e Allow to construct CMIUtilString using std::string directly + cleanup CMIUtilString (MI)
Summary:
Allow to construct CMIUtilString using std::string directly + cleanup CMIUtilString (MI)

This patch cleans up lldb-mi code, and serves to simplify
the following case:
```
  std::string strGoodbye = "!Hello";
  CMIUtilString strHello(strGoodbye.substr(1).c_str());
```

With CMIUtilString(std::string) we can omit .c_str():
```
  std::string strGoodbye = "!Hello";
  CMIUtilString strHello(strGoodbye.substr(1));
```

Also, it removes 2 ctors because they aren't needed:
# CMIUtilString::CMIUtilString(const char *const *vpData)
# CMIUtilString::CMIUtilString(const char *vpData, size_t nLen)
and cleans up CMIUtilString::operator=(const std::string &vrRhs).

Ilia K 69b95f49f1 Fix handling of double quotes (MI)
Summary:
* Clean CMICmdArgValString::Validate: now it's based on CMIUtilString::SplitConsiderQuotes method:
A bit of introduction:
# Command line is wrapped into CMICmdArgContext.
# CMICmdArgSet is a set of arguments to be parsed. This class contains CMICmdArgContext as a private member.
# MI command is class which is inhereted from CMICmdBase. It contains CMICmdArgSet as a private member.

When command is executed CMICmdBase::ParseArgs() is called. This method adds args for parsing using CMICmdArgSet::Add(). Then CMICmdBase::ParseValidateCmdOptions() is called, which calls CMICmdArgSet::Validate(). Then it gets a number of arguments (using SplitConsiderQuotes().array_length) and for each arguments registered in ParseArgs() tries to validate it using CMICmdArgValBase::Validate(). Every user commands parses this string again (first time it was made in SplitConsiderQuotes) and in case of CMICmdArgValString it was made incorrectly. It searches the first and last quotes (but it should be first and next after first). Besides, it was splitted into 4 cases. 
I'm just using SplitConsiderQuotes directly, and I don't split them by hand again. 

Actually, I think we should do so in every CMICmdArgVal_XXX::Validate() method.

* Enable MiInterpreterExecTestCase.test_lldbmi_target_create test
* Fix MiExecTestCase.test_lldbmi_exec_arguments_set test

All tests pass on OS X.

Summary:

* Fix process's output to stdout/stderr (MI):

But previously not all characters were escaped by CMICmnLLDBDebuggerHandleEvents::ConvertPrintfCtrlCodeToString and output of
```
printf("'\n` - it's \\n\x12\"\\\"")
```
looked like:
```
~"'\r\n` - it's \n"\""
```

This patch fixes it by using CMIUtilString::Escape method and now it looks like:
```
~"'\r\n` - it's \\n\x12\"\\\""

This method doesn't work properly. Here is an example:
```
CMIUtilString test("\"hello\" \"\\\" world \\\" !\"");
CMIUtilString::VecString_t res;

```
(lldb) print res

  [0] = (std::__1::string = "\"hello\"")
  [1] = (std::__1::string = "\"\\\"")

  [1] = (std::__1::string = "\"\\\" world \\\" !\"")
