Aaron Ballman d6459e5c43 Fixing a FIXME -- no longer using std::memcpy, since that would fail for non-trivial types. Replaced with std::copy. No functional changes intended since all uses of this functionality either use pointers or integers.

Dmitri Gribenko 0b2026de6b Comment parsing: remove HTML attribute validation
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.

Rafael Espindola b5b622a03c Drop non-cfi assembly support from clang.
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).

Ben Langmuir b92de02f17 Reapply r207477 and r207479 without cyclic dependency
Fixed by moving ProcessWarningOptions from Frontend into Basic. All of
the dependencies for ProcessWarningOptions were already in Basic, so
this was a small change.

Ben Langmuir be84adbf1b Check -Werror options during module validation
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.

David Majnemer 27d69dbbd0 CodeGen: Fix linkage of reference temporaries
Summary:
A reference temporary should inherit the linkage of the variable it

Alp Toker 59c6bc5882 libclang: split out the documentation comment API
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.

Alp Toker 87d3975369 libclang: remove 'CXDiagnostic_Remark'
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.)

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

Daniel Sanders 81ea601b54 [mips] Support 128-bit int in N32 ABI by overriding TargetInfo::hasInt128Type()
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.

Ben Langmuir ffbafa2af0 Do not print inferred submodules explicitly in __inferred_module.map
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.
