Nemanja Ivanovic 50f29e06a1 Enable support for __float128 in Clang
This patch corresponds to review:
http://reviews.llvm.org/D15120

It adds support for the __float128 keyword, literals and a target feature to
enable it. This support is disabled by default on all targets and any target
that has support for this type is free to add it.

Based on feedback that I've received from target maintainers, this appears to
be the right thing for most targets. I have not heard from the maintainers of
X86 which I believe supports this type. I will subsequently investigate the
impact of enabling this on X86.

Chuang-Yu Cheng 8eac7ae9ad [PPC64][VSX] Add a couple of new data types for vec_vsx_ld and vec_vsx_st intrinsics and fix incorrect testcases with minor refactoring
New added data types:
  vector double vec_vsx_ld (int, const double *);
  vector float vec_vsx_ld (int, const float *);
  vector bool short vec_vsx_ld (int, const vector bool short *);
  vector bool int vec_vsx_ld (int, const vector bool int *);
  vector signed int vec_vsx_ld (int, const signed int *);
  vector unsigned int vec_vsx_ld (int, const unsigned int *);

  void vec_vsx_st (vector double, int, double *);
  void vec_vsx_st (vector float, int, float *);
  void vec_vsx_st (vector bool short, int, vector bool short *);
  void vec_vsx_st (vector bool short, int, signed short *);
  void vec_vsx_st (vector bool short, int, unsigned short *);
  void vec_vsx_st (vector bool int, int, vector bool int *);
  void vec_vsx_st (vector bool int, int, signed int *);
  void vec_vsx_st (vector bool int, int, unsigned int *);

Also fix testcases which use non-vector argument version of vec_vsx_ld or
vec_vsx_st, but pass incorrect parameter.

Devin Coughlin b2d2a018d6 [analyzer] Nullability: Treat nil _Nonnull ivar as invariant violation.
Treat a _Nonnull ivar that is nil as an invariant violation in a similar
fashion to how a nil _Nonnull parameter is treated as a precondition violation.

This avoids warning on defensive returns of nil on defensive internal
checks, such as the following common idiom:

@class InternalImplementation
@interface PublicClass {
  InternalImplementation * _Nonnull _internal;
}
-(id _Nonnull)foo;
@end

@implementation PublicClass
-(id _Nonnull)foo {
  if (!_internal)
    return nil; // no-warning

  return [_internal foo];
}
@end

Akira Hatanaka 2d3690bc98 [ObjC] Pop all cleanups created in EmitObjCForCollectionStmt before
exiting the for-in loop.

This commit fixes a bug where EmitObjCForCollectionStmt didn't pop
cleanups for captures.

For example, in the following for-in loop, a block which captures self
is passed to foo1:

for (id x in [self foo1:^{ use(self); }]) {
  use(x);
  break;
}

Previously, the code in EmitObjCForCollectionStmt wouldn't pop the
cleanup for the captured self before exiting the loop, which caused
code-gen to generate an IR in which objc_release was called twice on
the captured self.

This commit fixes the bug by entering a RunCleanupsScope before the
loop condition is evaluated and forcing its cleanup before exiting the
loop.

FreeBSD uses LLVM's libunwind on FreeBSD/arm64 today (and is expected to

Devin Coughlin 49bd58f1eb [analyzer] Nullability: Suppress return diagnostics in inlined functions.
The nullability checker can sometimes miss detecting nullability precondition
violations in inlined functions because the binding for the parameter
that violated the precondition becomes dead before the return:

int * _Nonnull callee(int * _Nonnull p2) {
  if (!p2)
    // p2 becomes dead here, so binding removed.
    return 0; // warning here because value stored in p2 is symbolic.
  else
   return p2;
}

int *caller(int * _Nonnull p1) {
  return callee(p1);
}

The fix, which is quite blunt, is to not warn about null returns in inlined
methods/functions. This won’t lose much coverage for ObjC because the analyzer
always analyzes each ObjC method at the top level in addition to inlined. It
*will* lose coverage for C — but there aren’t that many codebases with C
nullability annotations.

Nico Weber fd3e1ad0ce clang-cl: Remove -isystem, add -imsvc.
r260990 exposed -isystem in clang-cl. -isystem adds a directory to the front of
the system include search path. The idea was to use this to point to a hermetic
msvc install, but as it turns out this doesn't work: -isystem then adds the
hermetic headers in front of clang's builtin headers, and clang's headers that
are supposed to wrap msvc headers (say, stdarg.h) aren't picked up at all
anymore.

So revert that, and instead expose -imsvc which works as if the passed
directory was part of %INCLUDE%: The header is treated as a system header, but
it is searched after clang's lib/Header headers.

Fixes half of PRPR26751.

Alexey Bataev ecba70f194 [OPENMP 4.0] Support for 'linear' clause in 'declare simd' directive.
The linear clause declares one or more list items to be private to a SIMD lane and to have a linear relationship with respect to the iteration space of a loop.
'linear' '(' <linear-list> [ ':' <linear-step> ] ')'
When a linear-step expression is specified in a linear clause it must be
either a constant integer expression or an integer-typed parameter that is specified in a uniform clause on the directive.
The special this pointer can be used as if was one of the arguments to the function in any of the linear, aligned, or uniform clauses.

'aligned' '(' <argument-list> [ ':' <alignment> ] ')'
The optional parameter of the aligned clause, alignment, must be a constant positive integer expression. If no optional parameter is specified, implementation-defined default alignments for SIMD instructions on the target platforms are assumed.
The special this pointer can be used as if was one of the arguments to the function in any of the linear, aligned, or uniform clauses.

To make kindof lookup work, we need to insert methods with different
context into the global pool, even though they have the same siganture.

Since diagnosis of availability is performed on the best candidate,
which is often the first candidate from the global pool, we prioritize
the methods that are unavaible or deprecated to the head of the list.

Since we now have more methods in the global pool, we need to watch
out for performance impact.
