r155047. See the LLVM log for the primary motivation:
  http://llvm.org/viewvc/llvm-project?rev=155047&view=rev

Primary commit r154828:
  - Several issues were raised in review, and fixed in subsequent
    commits.
  - Follow-up commits also reverted, and which should be folded into the
    original before reposting:
    - r154837: Re-add the 'undef BUILTIN' thing to fix the build.
    - r154928: Fix build warnings, re-add (and correct) header and
      license
    - r154937: Typo fix.

Please resubmit this patch with the relevant LLVM resubmission.

initialize an array of unsigned char. Outside C++11 mode, this bug was benign,
and just resulted in us emitting a constant which was double the required
length, padded with 0s. In C++11, it resulted in us generating an array whose
first element was something like  i8 ptrtoint ([n x i8]* @str to i8).

thinking of generalizing it to be able to specify other freedoms beyond accuracy
(such as that NaN's don't have to be respected).  I'd like the 3.1 release (the
first one with this metadata) to have the more generic name already rather than
having to auto-upgrade it in 3.2.

to do some operations first (e.g. a GEP), which can leave us with

__atomic_test_and_set, __atomic_clear, plus a pile of undocumented __GCC_*
predefined macros.

Implement library fallback for __atomic_is_lock_free and
__c11_atomic_is_lock_free, and implement __atomic_always_lock_free.

Contrary to their documentation, GCC's __atomic_fetch_add family don't
multiply the operand by sizeof(T) when operating on a pointer type.
libstdc++ relies on this quirk. Remove this handling for all but the
__c11_atomic_fetch_add and __c11_atomic_fetch_sub builtins.

Contrary to their documentation, __atomic_test_and_set and __atomic_clear
take a first argument of type 'volatile void *', not 'void *' or 'bool *',
and __atomic_is_lock_free and __atomic_always_lock_free have an argument
of type 'const volatile void *', not 'void *'.

With this change, libstdc++4.7's <atomic> passes libc++'s atomic test suite,
except for a couple of libstdc++ bugs and some cases where libc++'s test
suite tests for properties which implementations have latitude to vary.

llvm-svn: 154640

in general (such an atomic has boolean representation) and
specifically for IR generation of __c11_atomic_init. The latter also
means actually using initialization semantics for this initialization,
rather than just creating a store.

On a related note, make sure we actually put in non-atomic-to-atomic
conversions when performing an implicit conversion sequence. IR
generation is far too kind here, but we still want the ASTs to make
sense.

llvm-svn: 154612

This is not quite sufficient for libstdc++'s <atomic>: we still need
__atomic_test_and_set and __atomic_clear, and may need a more complete
__atomic_is_lock_free implementation.

We are also missing an implementation of __atomic_always_lock_free,
__atomic_nand_fetch, and __atomic_fetch_nand, but those aren't needed
for libstdc++.

case as we don't currently have any way of dumping target options or
otherwise observing this. Another small step toward fixing PR12380. With
this we generate TLS accesses using the static model instead of the
dynamic model, but we're still generating suboptimal code under the
mistaken assumption that the TLS offset might be greater than 2^32, and
therefor not viable as an immediate offset of a segment register.
