Richard Smith 0015f09877 Parsing support for C11's _Noreturn keyword. No semantics yet.

Richard Smith 01a7fba820 -Wunsequenced: if the LHS of an &&, || or ?: is not constant, check for
unsequenced operations in the RHS. We don't compare the RHS with the rest of
the expression yet; such checks will need care to avoid diagnosing unsequenced
operations which are both in conditionally-evaluated subexpressions which
actually can't occur together, such as in '(b && ++x) + (!b && ++x)'.

Kevin Enderby ae2ec4745f We want the dwarf AT_producer for assembly source files to match clang's
AT_producer.  Which includes clang's version information so we can tell
which version of the compiler was used.

This is second of the two steps to allow us to do this.  The first was a
change to llvm-mc with revision 172630 to provide a method to set the
AT_producer string.  This second step has the clang driver passing the value
of getClangFullVersion() via the new flag -dwarf-debug-producer when invoking
the integrated assembler on assembly source files.  Then using the new
setDwarfDebugProducer() method to set the AT_producer string.

Enrico Granata bcba2b2b75 <rdar://problem/12786725>
If there is any alive process being debugged, the user is asked for confirmation before quitting LLDB
This should prevent situations where the user mistakenly types "q" and LLDB slaughters their process without any mercy whatsoever
Since it can quickly get tedious, there is a new setting on the command interpreter to disable this and replicate the previous behavior

Bill Wendling da29e00578 Reverting r171325 & r172363. This was causing a mis-compile on the self-hosted LTO build bots.
Okay, here's how to reproduce the problem:

1) Build a Release (or Release+Asserts) version of clang in the normal way.

2) Using the clang & clang++ binaries from (1), build a Release (or
   Release+Asserts) version of the same sources, but this time enable LTO ---
   specify the `-flto' flag on the command line.

3) Run the ARC migrator tests:

    $ arcmt-test --args -triple x86_64-apple-darwin10 -fsyntax-only -x objective-c++ ./src/tools/clang/test/ARCMT/cxx-rewrite.mm

You'll see that the output isn't correct (the whitespace is off).

The mis-compile is in the function `RewriteBuffer::RemoveText' in the
clang/lib/Rewrite/Core/Rewriter.cpp file. When that function and RewriteRope.cpp
are compiled with LTO and the `arcmt-test' executable is regenerated, you'll see
the error. When those files are not LTO'ed, then the output of the `arcmt-test'
is fine.

It is *really* hard to get a testcase out of this. I'll file a PR with what I
have currently.

Peter Collingbourne 6600516a58 Have ReExec read environment from /proc/self/environ
It is possible for ReExec to be called before the C standard library
has initialised itself sufficiently for execv to work properly.
Fix this by parsing the environment ourselves and using execve.

Nico Weber 80a82761bd Formatter: Get bit tests in ifs right.
It's generally not possible to know if 'a' '*' 'b' is a multiplication
expression or a variable declaration with a purely lexer-based approach. The
formatter currently uses a heuristic that classifies this token sequence as a
multiplication in rhs contexts (after '=' or 'return') and as a declaration
else.

Because of this, it gets bit tests in ifs, such as "if (a & b)" wrong. However,
declarations in ifs always have to be followed by '=', so this patch changes
the formatter to classify '&' as an operator if it's at the start of an if
statement.

Before:
  if (a& b)
  if (int* b = f())

Now:
  if (a & b)
  if (int* b = f())

Chandler Carruth 0153800601 Add initial rough support for synthesizing linker options when passed
-fopenmp in the link step on Linux. There is probably more tweaking that
will need to take place to get good support for linking the relevant
libraries on all Linux distributions and/or on other platforms, but this
get's the ball moving and allows Clang to build programs which contain
OpenMP pragmas that can be safely ignored by a compiler that doesn't
implement them, and yet makes direct calls into the OpenMP runtime.

Daniel Jasper 11cb81cd6f Improve handling of comments in static initializers.
Also adding more tests.

We can now keep the formatting of something like:

static SomeType type = { aaaaaaaaaaaaaaaaaaaa, /* comment */
                         aaaaaaaaaaaaaaaaaaaa /* comment */,
                         /* comment */ aaaaaaaaaaaaaaaaaaaa,
                         aaaaaaaaaaaaaaaaaaaa, // comment
                         aaaaaaaaaaaaaaaaaaaa };

Note that the comment in the first line is handled like a trailing line comment
as that is likely what the user intended.
