Richard Smith d79514e24b [modules] Separately track whether an identifier's preprocessor information and
name lookup information have changed since deserialization. For a C++ modules
build, we do not need to re-emit the identifier into the serialized identifier
table if only the name lookup information has changed (and in all cases, we
don't need to re-emit the macro information if only the name lookup information
has changed).

Add -fcoroutines flag (just for -cc1 for now) to enable the feature. Early

Saleem Abdulrasool d170c4b57a Add -f[no-]declspec to control recognition of __declspec as a keyword
In versions of clang prior to r238238, __declspec was recognized as a keyword in
all modes.  It was then changed to only be enabled when Microsoft or Borland
extensions were enabled (and for CUDA, as a temporary measure).  There is a
desire to support __declspec in Playstation code, and possibly other
environments.  This commit adds a command-line switch to allow explicit
enabling/disabling of the recognition of __declspec as a keyword.  Recognition
is enabled by default in Microsoft, Borland, CUDA, and PS4 environments, and
disabled in all other environments.

Ulrich Weigand 3c5038a535 Add support for System z vector language extensions
The z13 vector facility has an associated language extension,
closely modeled on AltiVec/VSX.  The main differences are:

- vector long, vector float and vector pixel are not supported

- vector long long and vector double are supported (like VSX)

- comparison operators return a vector rather than a scalar integer

- shift operators behave like the OpenCL shift operators

- vector bool is only supported as argument to certain operators;
  some operators allow mixing a bool with a non-bool vector 

This patch adds clang support for the extension.  It is closely modelled
on the AltiVec support.  Similarly to the -faltivec option, there's a
new -fzvector option to enable the extensions (as well as an -mzvector
alias for compatibility with GCC).  There's also a separate LangOpt.

The extension as implemented here is intended to be compatible with
the -mzvector extension recently implemented by GCC.

Based on a patch by Richard Sandiford.

Douglas Gregor ab209d83be Implement the Objective-C __kindof type qualifier.
The __kindof type qualifier can be applied to Objective-C object
(pointer) types to indicate id-like behavior, which includes implicit
"downcasting" of __kindof types to subclasses and id-like message-send
behavior. __kindof types provide better type bounds for substitutions
into unspecified generic types, which preserves more type information.

Richard Smith 2aedca340c [modules] Before checking whether the controlling macro of a header is defined,
update the identifier in case we've imported a definition of the macro (and
thus the contents of the header) from a module.

Also fold ExternalIdentifierLookup into ExternalPreprocessorSource; it no longer
makes sense to keep these separate now that the only user of the former also
needs the latter.

Douglas Gregor aea7afdc13 Replace __double_underscored type nullability qualifiers with _Uppercase_underscored
Addresses a conflict with glibc's __nonnull macro by renaming the type
nullability qualifiers as follows:

  __nonnull -> _Nonnull
  __nullable -> _Nullable
  __null_unspecified -> _Null_unspecified

This is the major part of rdar://problem/21530726, but does not yet
provide the Darwin-specific behavior for the old names.

Hubert Tong 6e04f98bc3 [Concepts] lex keywords: concept and requires
Summary:
This patch enables lexing of `concept` and `requires` as keywords.
Further changes which add messages for future keyword compat are to
follow.

Test Plan:
Testing of C++14 + Concepts TS mode is added to
`test/Lexer/keywords_test.cpp`, which expects that the new keywords are
enabled under said mode.

Aaron Ballman 674cf26892 __declspec is not a core Clang language extension. Instead, require -fms-extensions or -fborland to enable the language extension.
Note: __declspec is also temporarily enabled when compiling for a CUDA target because there are implementation details relying on __declspec(property) support currently. When those details change, __declspec should be disabled for CUDA targets.

Serge Pavlov 1ecb41c09b Emit warning if define or undef reserved identifier or keyword.
Summary:
This change implements warnings if macro name is identical to a keyword or
reserved identifier. The warnings are different depending on the "danger"
of the operation. Defining macro that replaces a keyword is on by default.
Other cases produce warning that is off by default but can be turned on
using option -Wreserved-id-macro.

This change fixes PR11488.

compiling for non-OpenCL languages. This patch creates a new printing policy for
half in a similar manner to what is done for bool and wchar_t.

Alp Toker bfa3934f27 Rename language option MicrosoftMode to MSVCCompat
There's been long-standing confusion over the role of these two options. This
commit makes the necessary changes to differentiate them clearly, following up
from r198936.

MicrosoftExt (aka. fms-extensions):
 Enable largely unobjectionable Microsoft language extensions to ease
 portability. This mode, also supported by gcc, is used for building software
 like FreeBSD and Linux kernel extensions that share code with Windows drivers.

MSVCCompat (aka. -fms-compatibility, formerly MicrosoftMode):
 Turn on a special mode supporting 'heinous' extensions for drop-in
 compatibility with the Microsoft Visual C++ product. Standards-compilant C and
 C++ code isn't guaranteed to work in this mode. Implies MicrosoftExt.

Note that full -fms-compatibility mode is currently enabled by default on the
Windows target, which may need tuning to serve as a reasonable default.

See cfe-commits for the full discourse, thread 'r198497 - Move MS predefined
type_info out of InitializePredefinedMacros'

No change in behaviour.
