Will Dietz f54319c891 [ubsan] Add support for -fsanitize-blacklist

Kostya Serebryany 63c36bbe5e [asan] fix two off-by-one errors that seem to affect only PowerPC because only there the stack top may be equal to the address space top. Noted by Andreas Schwab in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55975#c11 . Also make swapcontext interceptor a bit more robust

Daniel Jasper 04468962ab Reduce penalty for splitting between ")" and ".".
').' is likely part of a builder pattern statement.
This is based upon a patch developed by Nico Weber. Thank you!

Before:
int foo() {
  return llvm::StringSwitch<Reference::Kind>(name).StartsWith(
      ".eh_frame_hdr", ORDER_EH_FRAMEHDR).StartsWith(
      ".eh_frame", ORDER_EH_FRAME).StartsWith(".init", ORDER_INIT).StartsWith(
      ".fini", ORDER_FINI).StartsWith(".hash", ORDER_HASH).Default(ORDER_TEXT);
}

After:
int foo() {
  return llvm::StringSwitch<Reference::Kind>(name)
         .StartsWith(".eh_frame_hdr", ORDER_EH_FRAMEHDR)
         .StartsWith(".eh_frame", ORDER_EH_FRAME)
         .StartsWith(".init", ORDER_INIT).StartsWith(".fini", ORDER_FINI)
         .StartsWith(".hash", ORDER_HASH).Default(ORDER_TEXT);
}

Probably not ideal, but makes many cases much more readable.

The changes to overriding-ftemplate-comments.cpp don't seem better or
worse. We should address those soon.

Jordan Rose 1eb342920b Format strings: don't ever convert %+d to %lu.
Presumably, if the printf format has the sign explicitly requested, the user
wants to treat the data as signed.

didn't make it into that commit.

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.

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.
