Richard Trieu db36469554 Create new diagnostic group -Wmove
-Wmove includes the three existing warnings for std::move calls, self move,
reduntant move, and pessimizing move.  -Wmove is included in -Wmost, so that
it can be discoverable to people using that or -Wall.

Richard Smith 2d4a11fba6 [modules] When a file is listed as a non-textual header in a module map, don't
enter it more than once, even if it doesn't have #include guards -- we already
know that it is intended to have the same effect every time it's included, and
it's already had that effect. This particularly helps with local submodule
visibility builds, where the include guard macro may not be visible in the
includer, but will become visible the moment we enter the included file.

Ismail Pazarbasi e5768d1717 Detect uses of mismatching forms of 'new' and 'delete'
Emit warning when operand to `delete` is allocated with `new[]` or
operand to `delete[]` is allocated with `new`.

rev 2 update:
`getNewExprFromInitListOrExpr` should return `dyn_cast_or_null`
instead of `dyn_cast`, since `E` might be null.

};
to avoid possible additional alignment bytes in first fields (shareds, routine, part_id and destructors). Runtime library is not aware of such kind additional alignment bytes.

Nico Weber 28e0f243cf Don't leak TemplateIds when a plugin parses late-parsed templates at TU end.
In -fdelayed-template-parsing mode, templates that aren't used are not parsed
at all.  For some diagnostic plugins, this is a problem since they want to
analyse the contents of the template function body.  What has been suggested
on cfe-dev [1] is to explicitly parse interesting templates in
HandleTranslationUnit(); IWYU does this for example [2].

This is workable, but since the delayed parsing doesn't run below a call to
ParseTopLevelDecl(), no DestroyTemplateIdAnnotationsRAIIObj object is on the
stack to clean up TemplateIds that are created during parsing.  To fix this,
let ~Parser() clean them up in delayed template parsing mode instead of
leaking (or asserting in +Assert builds).

(r219810, relanded in r220400, fixed the same problem in incremental processing
mode; the review thread of r219810 has a good discussion of the problem.)

To test this, give the PrintFunctionNames plugin a flag to force parsing
of a template and add a test that uses it in -fdelayed-template-parsing mode.
Without the Parser.cpp change, that test asserts.

Bill Schmidt 41e14c4dfa [PPC64] Add vector pack/unpack support from ISA 2.07
This patch adds support for the following new instructions in the
Power ISA 2.07:

  vpksdss
  vpksdus
  vpkudus
  vpkudum
  vupkhsw
  vupklsw

These instructions are available through the vec_packs, vec_packsu,
vec_unpackh, and vec_unpackl built-in interfaces.  These are
lane-sensitive instructions, so the built-ins have different
implementations for big- and little-endian, and the instructions must
be marked as killing the vector swap optimization for now.

The first three instructions perform saturating pack operations.  The
fourth performs a modulo pack operation, which means it can be
represented with a vector shuffle, and conversely the appropriate
vector shuffles may cause this instruction to be generated.  The other
instructions are only generated via built-in support for now.

I noticed during patch preparation that the macro __VSX__ was not
previously predefined when the power8-vector or direct-move features
are requested.  This is an error, and I've corrected that here as
well.

Appropriate tests have been added.

There is a companion patch to llvm for the rest of this support.

Richard Smith 4241314164 [modules] Add local submodule visibility support for declarations.
With this change, enabling -fmodules-local-submodule-visibility results in name
visibility rules being applied to submodules of the current module in addition
to imported modules (that is, names no longer "leak" between submodules of the
same top-level module). This also makes it much safer to textually include a
non-modular library into a module: each submodule that textually includes that
library will get its own "copy" of that library, and so the library becomes
visible no matter which including submodule you import.

Pirama Arumuga Nainar e9bcddd5cb Add flag to enable native half type
Summary:
r235215 enables support in LLVM for legalizing f16 type in the IR.  AArch64
already had support for this.  r235215 and some backend patches brought support
for ARM, X86, X86-64, Mips and Mips64.

This change exposes the LangOption 'NativeHalfType' in the command line, so the
backend legalization can be used if desired.  NativeHalfType is enabled for
OpenCL (current behavior) or if '-fnative-half-type' is set.

The test added also checks for named and auto objects.  It seems to make sense

David Majnemer 1b5baffd73 [MS ABI] __declspec(thread) behaves like thread_local in MSVC 2015
MSVC 2015 changed __declspec(thread) to make it behave like C++11's
thread_local keyword instead of acting similarly to __thread.

Richard Smith 31d5184dc5 Generalize future keyword compat diagnostics.
This, in preparation for the introduction of more new keywords in the
implementation of the C++ language, generalizes the support for future keyword
compat diagnostics (e.g., diag::warn_cxx11_keyword) by extending the
applicability of the relevant property in IdentifierTable with appropriate
renaming.

Richard Smith 23d8d0338e [modules] Fix a #include cycle when building a module for our builtin headers.
xmmintrin.h includes emmintrin.h and vice versa if SSE2 is enabled. We break
this cycle for a modules build, and instead make the xmmintrin.h module
re-export the immintrin.h module. Also included is a fix for an assert in the
serialization code if a module exports another module that was declared later
in the same module map.

Paul Robinson fcdf3e9fe7 Break \# in a depfile the same way as gcc.
Backslash followed by # in a filename should have both characters
escaped, if you do it the way GNU Make wants.  GCC doesn't, so we do
it the way GCC does rather than the way GNU Make wants.

Peter Collingbourne 470d94247d Make GNUInline consistent with whether we use traditional GNU inline semantics.
Previously we were setting LangOptions::GNUInline (which controls whether we
use traditional GNU inline semantics) if the language did not have the C99
feature flag set. The trouble with this is that C++ family languages also
do not have that flag set, so we ended up setting this flag in C++ modes
(and working around it in a few places downstream by also checking CPlusPlus).

The fix is to check whether the C89 flag is set for the target language,
rather than whether the C99 flag is cleared. This also lets us remove most
CPlusPlus checks. We continue to test CPlusPlus when deciding whether to
pre-define the __GNUC_GNU_INLINE__ macro for consistency with GCC.

There is a change in semantics in two other places
where we weren't checking both CPlusPlus and GNUInline
(FunctionDecl::doesDeclarationForceExternallyVisibleDefinition and
FunctionDecl::isInlineDefinitionExternallyVisible), but this change seems to
put us back into line with GCC's semantics (test case: test/CodeGen/inline.c).

While at it, forbid -fgnu89-inline in C++ modes, as GCC doesn't support it,
it didn't have any effect before, and supporting it just makes things more
complicated.

Paul Robinson 64441def58 Fix dependency file escaping.
When writing a dependency (.d) file, if space or # is immediately
preceded by one or more backslashes, escape the backslashes as well as
the space or # character. Otherwise leave backslash alone.
This straddles the fence between BSD Make (which does no escaping at
all, and does not support space or # in filespecs) and GNU Make (which
does support escaping, but will fall back to the filespec as-written
if the escaping doesn't match an existing file).

Daniel Jasper c4144ea418 clang-format: Improve nested block / lambda indentation when wrapping

Basically, it doesn't seem right to indent a nested block aligned to a
binary or ternary operator.

                 : [] {
                   return 2;  //
                 }();
  llvm::errs() << "number of twos is "
               << std::count_if(v.begin(), v.end(), [](int x) {
                 return x == 2;  // force break
               });

After:
  int i = aaaaaa ? 1  //
                 : [] {

Previously, if a semi-colon is unexpectedly added before a closing ')', ']' or

to which scope it was in.  This change consumes the semi-colon, recovers
parsing better, and emits only one error with a fix-it.

Artem Belevich ed0577cc6d Fixed double-free in case of module loading error.
GetOutputStream() owns the stream it returns pointer to and the
pointer should never be freed by us. When we fail to load and exit
early, unique_ptr still holds the pointer and frees it which leads to
compiler crash when CompilerInstance attempts to free it again.

Added regression test for failed bitcode linking.
