Since the community says that a blacklist is not good enough, and I don't have
enough time now to implement a proper whitelist, let's just remove the
attribute validation.
But, nevertheless, we can still communicate in the generated XML if our parser
found an issue with the HTML. But this bit is best-effort and is specifically
called out in the schema as such.

After this patch clang will ignore -fdwarf2-cfi-asm and -ffno-dwarf2-cfi-asm and
always print assembly that uses cfi directives.
In llvm, MC itself supports cfi since the end of 2010 (support started
in r119972, is reported in the 2.9 release notes).
In binutils the support has been around for much longer. It looks like
support started to be added in May 2003. It is available in 2.15
(31-Aug-2011, 2.14 is from 12-Jun-2003).

Fixed by moving ProcessWarningOptions from Frontend into Basic. All of
the dependencies for ProcessWarningOptions were already in Basic, so
this was a small change.

This patch checks whether the diagnostic options that could lead to
errors (principally -Werror) are consistent between when a module was
built and when it is loaded. If there are new -Werror flags, then the
module is rebuilt. In order to canonicalize the options we do this
check at the level of the constructed DiagnosticsEngine, which contains
the final set of diag to diagnostic level mappings. Currently we only
rebuild with the new diagnostic options, but we intend to refine this in
the future to include the union of the new and old flags, since we know
the old ones did not cause errors. System modules are only rebuilt when
-Wsystem-headers is enabled.
One oddity is that unlike checking language options, we don’t perform
this diagnostic option checking when loading from a precompiled header.
The reason for this is that the compiler cannot rebuild the PCH, so
anything that requires it to be rebuilt effectively leaks into the build
system. And in this case, that would mean the build system
understanding the complex relationship between diagnostic options and
the underlying diagnostic mappings, which is unreasonable. Skipping the
check is safe, because these options do not affect the generated AST.
You simply won’t get new build errors due to changed -Werror options
automatically, which is also true for non-module cases.

Summary:
A reference temporary should inherit the linkage of the variable it
initializes. Otherwise, we may hit cases where a reference temporary
wouldn't have the same value in all translation units.

It's possible that the "comment AST" may be replaced or split out in the
midterm, any anyway this makes the headers easier to read.
Developers don't currently need to include "clang-c/Documentation.h" explicitly
and there's no macro to test for availability yet.
The raw comment and brief comment accessors have been kept in Index.h though
brief support may also move here as a separate proposal.
This is not a deprecation, just a gentle separation of concerns as we look to
simplify the built-in representation of comment nodes and support external
comment processors.

The change was landed without review or test cases.
It trivially broke almost any stable application checking for Severity >=
CXDiagnostic_Error or indeed any other kind of severity comparison upon
encountering a 'remark'.
Mapped to CXDiagnostic_Warning until a workable solution is proposed to the
list that preserves API stability.
(It's also not clear why the rest of r202475 wasn't simply implemented as a
modifier to the existing 'warning' level.)

The __yield intrinsic generates a hint instruction to indicate that the thread
is not performing any useful operations at the moment. This is for
compatibility with MSVC, although, the intrinsic is also part of the ACLE, and
is enabled globally as a result.

This patch:
1. Adds a definition for two new GCCBuiltins in BuiltinsX86.def:
__builtin_ia32_rdtsc;
__builtin_ia32_rdtscp;
2. Replaces the already existing definition of intrinsic __rdtsc in
ia32intrin.h with a simple call to the new GCC builtin __builtin_ia32_rdtsc.
3. Adds a definition for the new intrinsic __rdtscp in ia32intrin.h

Summary: The condition in the base class is rather strange. It says a target has the 128-bit integer type if the size of a pointer is >= 64-bits. N32 has 32-bit pointers but 64-bit integers. I'm a bit reluctant to change this for all targets so this patch makes the method virtual and overrides it for MIPS64.

Otherwise including a header in your source file that is not included by
framework's umbrella header will silently add an empty submodule with that
name.
is automatically translated to
@import Foo.NotInModule;
which then would have succeeded because the inferred module map
contained an empty submodule called NotInModule.

We don't need the ASTContext for the diagnostics, only the language
options, which we can get from the compiler invocation. It worries me
how many categorically different states the ASTUnit class can be in
depending on how it is being constructed/used.

Attribute filtering is currently based on a blacklist, which right now includes
all event handler attributes (they contain JavaScipt code). It should be
switched to a whitelist, but going over all of the HTML5 spec requires a
significant amount of time.

In passing, add that warning to -Wdeprecated, where it belongs.
