This makes it consistent with -fdump-record-layouts, which was moved to
outs() in r186219. My reasoning for going with stdout is that when one
of these options is present, the layouts are really a program output,
and shouldn't be interleaved with diagnostics, which are on stderr.

Before:
unsigned ContentSize =
sizeof(int16_t) // DWARF ARange version number
+
sizeof(int32_t) // Offset of CU in the .debug_info section
+
sizeof(int8_t) // Pointer Size (in bytes)
+
sizeof(int8_t); // Segment Size (in bytes)
After:
unsigned ContentSize =
sizeof(int16_t) // DWARF ARange version number
+ sizeof(int32_t) // Offset of CU in the .debug_info section
+ sizeof(int8_t) // Pointer Size (in bytes)
+ sizeof(int8_t); // Segment Size (in bytes)
This fixes llvm.org/PR17687.

I've added the missing ImutProfileInfo [sic] specialization for bool,
so this patch on r194235 is no longer needed.
This reverts r194244 / 2baea2887dfcf023c8e3560e5d4713c42eed7b6b.

Switch clang-format over to Rewriter::overwriteChangedFiles().
The previous implementation was attempting to stream back directly to the
original file and failing if it was already memory mapped by MemoryBuffer,
an operation unsupported by Windows.
MemoryBuffer generally mmaps files larger than the physical page size so
this will have been difficult to reproduce consistently.
This change also reduces flicker in code editors and IDEs on all platforms
when reformatting in-place.
Note that other incorrect uses of MemoryBuffer exist in LLVM/clang and
will need a similar fix.
A test should be added for Windows when libFormat performance issues are
fixed (it takes longer than a day to format a 1MB file at present!)

It's better to test clang-check rather than the internal c-index-test utility.
Also adds a target so we can remove the XFAILs.
Thanks to Richard Barton for spotting the test failure on ARM.
Test originally from r193685.

A column limit in the test folder can lead to trouble as the RUN, CHECK,
etc. comments can potentially be broken over multiple lines changing
their meaning. Without column limit, clang-format will simply keep the
test author's line breaks.

For i686 targets and LLP64 targets, we can see;
error: 'error' diagnostics seen but not expected:
File clang/test/CXX/drs/dr1xx.cpp Line 761: 'check7a' declared as an array with a negative size
File clang/test/CXX/drs/dr1xx.cpp Line 765: 'check8a' declared as an array with a negative size
2 errors generated.

In ADT/ImmutableSet, ImutProfileInfo<bool> cannot be matched to ImutProfileInteger.
I didn't have idea it'd the right way if PROFILE_INTEGER_INFO(bool) could be added there.

Under ARC++, a reference to a const Objective-C pointer is implicitly
treated as __unsafe_unretained, and can be initialized with (e.g.) a
__strong lvalue. Make sure this behavior does not break template
argument deduction and (related) that partial ordering still prefers a
'T* const&' template over a 'T const&' template when this case kicks
in. Fixes <rdar://problem/14467941>.

This syntactic checker looks for expressions on both sides of comparison
operators that are structurally the same. As a special case, the
floating-point idiom "x != x" for "isnan(x)" is left alone.
Currently this only checks comparison operators, but in the future we could
extend this to include logical operators or chained if-conditionals.
Checker by Per Viberg!

An Objective-C for-in loop will have zero iterations if the collection is
empty. Previously, we could only detect this case if the program asked for
the collection's -count /before/ the for-in loop. Now, the analyzer
distinguishes for-in loops that had zero iterations from those with at
least one, and can use this information to constrain the result of calling
-count after the loop.
In order to make this actually useful, teach the checker that methods on
NSArray, NSDictionary, and the other immutable collection classes don't
change the count.

The path note that says "Loop body executed 0 times" has been changed to
"Loop body skipped when range is empty" for C++11 for-range loops, and to
"Loop body skipped when collection is empty" for Objective-C for-in loops.

The preprocessor currently recognizes module declarations to load a
module based on seeing the 'import' keyword followed by an
identifier. This sequence is fairly unlikely in C (one would need a
type named 'import'), but is more common in Objective-C (where a
variable named 'import' can cause problems). Since import declarations
currently require a leading '@', recognize that in the preprocessor as
well. Fixes <rdar://problem/15084587>.
llvm-svn: 194225
When performing an Objective-C message send to a value of class type,
perform a contextual conversion to an Objective-C pointer type. We've
had this for a long time, but it recently regressed. Fixes
<rdar://problem/15234703>.
llvm-svn: 194224
As a side-effect, constructors definitions will correctly be recognized
and formatted as function declarations. Tests will be added in a
follow-up patch actually using the correct recognition.

Also - others have complained about some white space issues - sorry about that - continues to be a pain point for me - will try and see what I can do with clang-format this evening after work - as a short term fix, if anyone can email me the files that they have already identified with issues, it would help me speed up a focused fix. sorry.
