Daniel Jasper 2603ee0dc6 Improve formatting of stream operators.
If there are string literals on either side of a '<<', chances are
high that they represent logically separate concepts. Otherwise,
the author could just have just a single literal (possible split
over multiple lines).

So, we can now nicely format things like:
cout << "somepacket = {\n"
     << "  val a = " << ValueA << "\n"
     << "  val b = " << ValueB << "\n"
     << "}";

Daniel Jasper 1f140981b6 Improve handling of trailing block comments.
We can now (even in non-bin-packing modes) format:
someFunction(1, /* comment 1 */
             2, /* comment 2 */
             3, /* comment 3 */
             aaa);

Daniel Jasper f7f13c0ef2 Fix an error in formatting of for-loops.
Two minor changes:
* Slight penalty for breaking at "," as opposed to ";".
* Don't apply bin-packing rules to for-loops.

Before:
for (int aaaaaa = aaaaaaaaaa; aaaaaa < bbbbbbbb; ++aaaaaa,
         ++ccccccccccccccc) {}

After:
for (int aaaaaa = aaaaaaaaaa; aaaaaa < bbbbbbbb;
     ++aaaaaa, ++ccccccccccccccc) {}

Daniel Jasper 3a9370cbca Restructuring of token annotation for formatting.
This combines several changes:
* Calculation token type (e.g. for * and &) in the AnnotatingParser.
* Calculate the scope binding strength in the AnnotatingParser.
* Let <> and [] scopes bind stronger than () and {} scopes.
* Add minimal debugging output.

Evgeniy Stepanov 1f5a71492d More MSan/ASan annotations.
This change lets us bootstrap LLVM/Clang under ASan and MSan. It contains
fixes for 2 issues:

- X86JIT reads return address from stack, which MSan does not know is
  initialized.
- bugpoint tests run binaries with RLIMIT_AS. This does not work with certain
  Sanitizers.

We are no longer including config.h in Compiler.h with this change.

Arnold Schwaighofer 98f1012f9b ARM cost model: Penalize insertelement into D subregisters
Swift has a renaming dependency if we load into D subregisters. We don't have a
way of distinguishing between insertelement operations of values from loads and
other values. Therefore, we are pessimistic for now (The performance problem
showed up in example 14 of gcc-loops).

Edwin Vane a9c5bb3ff3 Turn off uninitialized-use warnings for gcc in cmake build
Added support to the cmake build to turn off uninitialized use warnings
for gcc. This cleans the build up somewhat.

Used logic simpler than found in autoconf by making use of the fact that
although gcc won't complain about unsupported -Wno-* flags it *will*
complain about unsupported -W flags.

Dmitri Gribenko b614fab39d DeclPrinter: fix CXXConstructExpr printing with implicit default argument
This is an improvement of r173630, that handles the following case:

  struct VirualDestrClass
  {
    VirualDestrClass(int arg);
    virtual ~VirualDestrClass();
  };

  struct ConstrWithCleanupsClass
  {
    ConstrWithCleanupsClass(const VirualDestrClass& cplx = VirualDestrClass(42));
  };

  ConstrWithCleanupsClass cwcNoArg;

That was printed as:

  ConstrWithCleanupsClass cwcNoArg();

Michael Gottesman 4c4ffd7783 Added instance variable/initializers/getter/setters for new keyword externally initialized to GlobalVariable. No *TRUE* functionality change.
I am going to add in the actual test cases with the actual functionality
changes in a later patch because I want to include some test cases.

To be clear when I say no *TRUE* functionality change I mean that this
patch (like it says in the title) only contains getters/setters and sets
up a default initial value of the instance variable to false so that
this patch does not affect any other uses of Global Variable.h.

Benjamin Kramer d9c8455adf CodeGen: Implement hint values for dynamic_cast as described in the Itanium C++ ABI.
This can yield dramatic speedups of dynamic_cast for simple inheritance trees,
at least with libsupc++. Neither libcxxabi nor libcxxrt make use of this
hint currently, it was never implemented because clang didn't support it.

There was some concern about the number of class hierarchy walks this change
introduces. If it turns out to be an issue we can add caching either at the cast
pair level or even deeper, but we also do a lot of walks in Sema so this
codepath is probably fairly optimized already.

Daniel Jasper 1ca05ccf68 Fix bug in formatting of nested initializers.
We can now format:
SomeArrayOfSomeType a = { { { 1, 2, 3 } }, { { 1, 2, 3 } },
                          { { 111111111111111111111111111111,
                              222222222222222222222222222222,
                              333333333333333333333333333333 } },
                          { { 1, 2, 3 } }, { { 1, 2, 3 } } };

Before, we did strange things there.

Michael J. Spencer 9718f45d39 [Object][Archive] Improve performance.
Improve performance of iterating over children and accessing the member file
buffer by caching the file size and moving code out to the header.

This also makes getBuffer return a StringRef instead of a MemoryBuffer. Both
fixing a memory leak and removing a malloc.

This takes getBuffer from ~10% of the time in lld to unmeasurable.

Michael Gottesman ef2bc77330 Added clarification paragraph to LangRef's documentation of
GlobalVariable about LLVM's assumptions vis-a-vis Global Variable
initial values and Global Variable initializers.

This is in preparation for adding the new keyword
externally_initialized.

Specifically, the patch explains how LLVM optimizes global initializers
by assumign that global variables defined within the module are not
modified from their initial values before the start of the global
initializer.

David Blaikie 33111dfea0 Remove the (apparently) unnecessary debug info metadata indirection.
The main lists of debug info metadata attached to the compile_unit had an extra
layer of metadata nodes they went through for no apparent reason. This patch
removes that (& still passes just as much of the GDB 7.5 test suite). If anyone
can show evidence as to why these extra metadata nodes are there I'm open to
reverting this patch & documenting why they're there.

Richard Smith c084bd2888 PR15132: Replace "address expression must be an lvalue or a function
designator" diagnostic with more correct and more human-friendly "cannot take
address of rvalue of type 'T'".

For the case of & &T::f, provide a custom diagnostic, rather than unhelpfully
saying "cannot take address of rvalue of type '<overloaded function type>'".

For the case of &array_temporary, treat it just like a class temporary
(including allowing it as an extension); the existing diagnostic wording
for the class temporary case works fine.
