Daniel Jasper 1699eca119 clang-format: [JS] Making arrow function wrapping more consistent.
Before:
  someFunction(() =>
               {
                 doSomething();  // break
               })
      .doSomethingElse(  // break
          );

After:
  someFunction(() => {
    doSomething();  // break
  })
      .doSomethingElse(  // break
          );

This is still bad, but at least it is consistent with what we do for other
function literals. Added corresponding tests.

David Majnemer f04e3862ca [MS ABI] Be a little more defensive wrt vector types
We probably shouldn't say that all appropriately sized vector types are
intel vector types (i.e. __m128, etc.) as they don't exist for all
architectures.  While this is largely academic, it'd save some debugging
if we supported such a platform.

Ahmed Bougacha 5b63908f9f [Sema] Promote compound assignment exprs. with fp16 LHS and int. RHS.
We catch most of the various other __fp16 implicit conversions to
float, but not this one:

  __fp16 a;
  int i;
  ...
  a += i;

For which we used to generate something 'fun' like:

  %conv = sitofp i32 %i to float
  %1 = tail call i16 @llvm.convert.to.fp16.f32(float %conv)
  %add = add i16 %0, %1

Instead, when we have an __fp16 LHS and an integer RHS, we should
use float as the result type.

While there, add a bunch of missing tests for mixed
__fp16/integer expressions.

Alexander Musman 94f14d9b73 Fix assertion on C++ attributes in fillAttributedTypeLoc
this fixes http://llvm.org/PR17424
fillAttributedTypeLoc() function is only called with AttributeLists of either
DeclarationChunk (which is used for each type in a declarator being parsed) or
DeclSpec (which captures information about declaration specifiers).
As C++11 attributes actually appertain to declarators, they are moved straight
to the declarator’s attr list in distributeFunctionTypeAttrFromDeclSpec()
function.
'Put them wherever you like' semantics is not supported for C++11 attributes
(but is allowed for GNU attributes, for example). So when we meet an attribute
while parsing the declaration, we cannot be sure if it appertains to either
DeclarationChunk or DeclSpec.

This investigation correlates with the history of changes of SemaType.cpp:
• Asserts in fillAttributedTypeLoc() were added on 3 Mar 2011 in r126986
(http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-
        20110228/039638.html);
• Distributing C++11 attrs to the declarator was added on 14 Jan 2013
in r172504 (http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-
        20130114/071830.html).
Considering all written above I changed asserts in fillAttributedTypeLoc()
to nullptr checks.

This fixes PR17424 and related assertion on
[[gnu::fastcall]] void __stdcall foo();

Chandler Carruth 9c6b4f8528 [omp] Re-work Clang's handling of -fopenmp and undo r237769.
This isn't an actual revert of r237769, it just restores the behavior of
the Clang driver prior to it while completely re-implementing how that
behavior works.

This also re-does the work of making the default OpenMP runtime
selectable at CMake (or configure) time to work in the way all of our
other such hooks do (config.h, configure and cmake hooks, etc.).

I've re-implemented how we manage the '-fopenmp' flagset in an important
way. Now, the "default" hook just makes '-fopenmp' equivalent to
'-fopenmp=<default>' rather than a separate special beast. Also, there
is an '-fno-openmp' flag which does the obvious thing. Also, the code is
shared between all the places to select a known OpenMP runtime and act
on it.

Finally, and most significantly, I've taught the driver to inspect the
selected runtime when choosing whether to propagate the '-fopenmp' flag
to the frontend in the CC1 commandline. Without this, it isn't possible
to use Clang with libgomp, even if you were happy with the serial,
boring way in which it worked previously (ignoring all #pragmas but
linking in the library to satisfy direct calls into the runtime).

While I'm here, I've gone ahead and sketched out a path for the future
name of LLVM's OpenMP runtime (libomp) and the legacy support for its
current name (libiomp5) in what seems a more reasonable way.

To re-enable LLVM's OpenMP runtime (which I think should wait until the
normal getting started instructions are a reasonable way for falks to
check out, build, and install Clang with the runtime) all that needs to
change is the default string in the CMakeLists.txt and configure.ac
file. No code changes necessary.

I also added a test for the driver's behavior around OpenMP since it was
*completely missing* previously. Makes it unsurprising that we got it
wrong.

David Majnemer 34568bc602 [MS ABI, DebugInfo] Omit the size for model-less pointers-to-members
The representation of a pointer-to-member in the MS ABI is governed by
the layout of the relevant class or if a model has been explicitly
specified.  If no model is specified, then an appropriate
"worst-case-scenario" model is implicitly chosen if, and only, if the
pointer-to-member type's representation was needed.

Debug info cannot force a pointer-to-member type to have a
representation so do not try to query the size of such a type unless we
know it is safe to do so.

Faisal Vali 24d59d14ba "This adds -fconcepts-ts as a cc1 option for enabling the
in-progress implementation of the Concepts TS. The recommended feature
test macro __cpp_experimental_concepts is set to 1 (as opposed to
201501) to indicate that the feature is enabled, but the
implementation is incomplete.

The link to the Concepts TS in cxx_status is updated to refer to the
PDTS (N4377). Additional changes related to __has_feature and
__has_extension are to follow in a later change.

Relevant tests include:

test/Lexer/cxx-features.cpp

The test file is updated with testing of the C++14 + Concepts TS mode.
The expected behaviour is the same as that of the C++14 modes except
for the case of __cpp_experimental_concepts."

- Hubert Tong.

John Brawn 94fd963315 [ARM] Restructure cpu handling in the driver to mostly use the triple
Using the target cpu to determine some behaviour is sprinkled in
several places in the driver, but in almost all the information that
is needed can be found in the triple. Restructure things so that the
triple is used, and the cpu is only used if the exact cpu name is
needed.

Also add a check that the -mcpu argument is valid, and correct the
-march argument checking so that it handles -march=native correctly. I
would have liked to move these checks into the computation of the
triple, but the triple is calculated several times in several places
and that would lead to multiple error messages for the same thing.

Alexey Bataev 15413ea02b [MSVC] Handle out-of-line definition of static data member correctly (fix for http://llvm.org/PR21164), by Alexey Frolov
There are 3 cases of defining static const member:

initialized inside the class, not defined outside the class.
initialized inside the class, defined outside the class.
not initialized inside the class, defined outside the class.
Revision r213304 was supposed to fix the linkage problem of case (1), but mistakenly it made case (2) behave the same.
As a result, out-of-line definition of static data member is not handled correctly.
Proposed patch distinguishes between cases (1) and (2) and allows to properly emit static const members under –fms-compatibility option.

Alexey Bataev 16dc7b68c4 Fix for aggregate copying of variable length arrays.
Patch fixes codegen for aggregate copying of VLAs. Currently method CodeGenFunction::EmitAggregateCopy() does not support copying of VLAs. Patch checks if the size of the type is 0, then checks if the type is actually a variable-length array. Then it calculates total length for this array and calculates total size of the array in bytes:

<total number of elements in array> * aligned_sizeof(ElementType) (if copy assignment is requested).
If simple copying is requested, size is calculated like:

<total number of elements in array> * aligned_sizeof(ElementType) - aligned_sizeof(ElementType) + sizeof(ElementType).
memcpy() is used with this calculated size of the VLA.

Alexey Bataev 8fc69dcf42 [OPENMP] Fix for '#pragma omp task' codegen.
Internal task structure must be generated like
typedef struct kmp_task {
  void *              shareds;
  kmp_routine_entry_t routine;
  kmp_int32           part_id;

} kmp_task_t;

struct kmp_task_t_with_privates {
  kmp_task_t task_data;
  .kmp_private. privates;
};
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.

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.

Richard Trieu 1d3b58e317 Add a new error for unexpected semi-colon before closing delimiter.
Previously, if a semi-colon is unexpectedly added before a closing ')', ']' or
'}', two errors and one note would emitted, and the parsing would get confused
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.

Renato Golin cb3b0c6eeb Change TargetParser enum names to avoid macro conflicts (clang)
sys/time.h on Solaris (and possibly other systems) defines "SEC" as "1"
using a cpp macro.  The result is that this fails to compile.

Manuel Klimek 3d3ea84a4f Refactor clang-format's formatter.
Summary:
a) Pull out a class LevelIndentTracker whose responsibility is to keep track
   of the indent of levels across multiple annotated lines.
b) Put all responsibility for merging lines into the LineJoiner; make the
   LineJoiner iterate over the lines so we never operate on a line that might
   be merged later; this makes the interface safer to use.
c) Move formatting of the end-of-file whitespace into formatFirstToken.

Fix bugs that became obvious after the refactoring:
1. We would not format lines with offsets correctly inside nested blocks if
   only the outer expression was affected:
   int x = s({ // clang-format only this line
     class X {
       public:
    // ^ this starts at the non-modified indnent level; previously we would
    //   not fix this, now we correctly outdent it.
       void f();
     };
   });
2. We would incorrectly align comments across lines that do not have comments
   for lines with nested blocks:
   int expression; // with comment
   int x = s({
     int y; // comment
     int z; // we would incorrectly align this comment with the comment on
            // 'expression'
   });

Alexey Bataev 040d540940 [OPENMP] Fixed support for 'schedule' clause with non-constant chunk size.
'schedule' clause for combined directives requires additional processing. Special helper variable is generated, that is captured in the outlined parallel region for 'parallel for' region. This captured variable is used to store chunk expression from the 'schedule' clause in this 'parallel for' region.

Justin Bogner 2fd95f6b92 Driver: Fix a -Wshadow issue from r237091
The MachO toolchain has an isTargetIOSBased method, but it isn't
virtual so it isn't very meaningful to call it. After thinking about
this, I guess that putting this logic in the MachO class is a bit of a
layering violation anyway. Do this more like how we handle
AddLinkRuntimeLibArgs instead.
