The commit added a source location that used to be missing from the AST.

I introduced this bug in 198815. Thanks for Mark Lacey for noticing.
Unfortunately, I have no idea how to test this code.

Preserves the setting of -fretain-comments-from-system-headers when
building/saving/loading module files. This allows code completion to pick up
documentation comments from system modules.

Fixes <rdar://problem/15596883>

In ARC, __attribute__((objc_precise_lifetime)) guarantees that the
object stored in it will survive to the end of the variable's formal
lifetime.  It is therefore useful even if it completely unused.

I would not normally add tests like these, but the copy constructor is not
used at all in our codebase with c++11, so having this tests might prevent
breaking the c++03 build again.

To declare or define reserved identifers is undefined behaviour in standard
C++. This needs to be addressed in compiler-rt before it can be used in LLVM.

See the list discussion for details.

This reverts commit r198858.

llvm-svn: 198884

Removing a bit of custom parsing functionality used by the thread safety analysis APIs. Now using tablegen to determine whether an attribute's arguments should be parsed in an unevaluated context instead of relying on a separate, hard-coded list of attributes.

Fix PR18404 - 'Bug in regex_token_iterator::operator++(int) implementation'. Enhance the tests for regex_token_iterator and regex_iterator.

While it is allowed to not have an @ on subsequent lines, it seems
general practice to add them. If undesired, the code author can easily
remove them again and clang-format won't re-add them.

- Format a braced list with one element per line if it has nested
  braced lists.
- Use a column layout only when the list has 6+ elements (instead of the
  current 4+ elements).

from the global address space (6.5.1 of the OpenCL 1.2 specification).
This makes clang construct the image arguments in the global address 
space and generate the argument metadata with the correct address space 
descriptor.

check-clang: Add dependencies to PrintFunctionNames and SampleAnalyzerPlugin, for r198747 and r198820.

It caused undefined behavior. DwarfTypeUnit::Ty might not be initialized properly, I guess.

The zext handling added in r197802 wasn't right for RNSBG.  This patch
restricts it to ROSBG, RXSBG and RISBG.  (The tests for RISBG were added
in r197802 since RISBG was the motivating example.)

llvm-svn: 198862

At the moment we expect rotates to have the form:

   (or (shl X, Y), (shr X, Z))

where Y == bitsize(X) - Z or Z == bitsize(X) - Y.  This form means that
the (or ...) is undefined for Y == 0 or Z == 0.  This undefinedness can
be avoided by using Y == (C * bitsize(X) - Z) & (bitsize(X) - 1) or
Z == (C * bitsize(X) - Y) & (bitsize(X) - 1) for any integer C
(including 0, the most natural choice).

llvm-svn: 198861

InstCombine converts (sub 32, (add X, C)) into (sub 32-C, X),
so a rotate left of a 32-bit Y by X+C could appear as either:

   (or (shl Y, (add X, C)), (shr Y, (sub 32, (add X, C))))

without InstCombine or:

   (or (shl Y, (add X, C)), (shr Y, (sub 32-C, X)))

with it.

We already matched the first form.  This patch handles the second too.

llvm-svn: 198860

This should fix the buildbots.

root path to which object files managed by the LLIObjectCache instance should be
written. This option defaults to "", in which case objects are cached in the
same directory as the bitcode they are derived from.

The load-object-a.ll test has been rewritten to use this option to support
testing in environments where the test directory is not writable.

Rename bytecode to opcodes to make it more clear.  Change an impossible case to
llvm_unreachable instead.  Avoid allocation of a buffer by modifying the
PrintOpcodes iteration.

Explicitly handle endianness to ensure that bytes are read properly on
