Sean Silva 00bd0a4034 Remove bad test.
We currently don't canonicalize paths in the preprocessed files.
But we do when writing to PCH.
This causes a discrepancy on Windows with the test below.
This test fails even on unix if you change the test to use
`%S//preprocess.h`.

I am led to conclude that the invariant that this test was intending to
test has not been upheld for a while (and may never have been).

Adrian Prantl e50371b948 Wrap clang modules and pch files in an object file container.
This patch adds ObjectFilePCHContainerOperations uses the LLVM backend
to put the contents of a PCH into a __clangast section inside a COFF, ELF,
or Mach-O object file container.

This is done to facilitate module debugging by makeing it possible to
store the debug info for the types defined by a module alongside the AST.

Douglas Gregor 1ac1b63c9c Implement variance for Objective-C type parameters.
Introduce co- and contra-variance for Objective-C type parameters,
which allows us to express that (for example) an NSArray is covariant
in its type parameter. This means that NSArray<NSMutableString *> * is
a subtype of NSArray<NSString *> *, which is expected of the immutable
Foundation collections.

Type parameters can be annotated with __covariant or __contravariant
to make them co- or contra-variant, respectively. This feature can be
detected by __has_feature(objc_generics_variance). Implements
rdar://problem/20217490.

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.

Douglas Gregor e83b95641f Substitute type arguments into uses of Objective-C interface members.
When messaging a method that was defined in an Objective-C class (or
category or extension thereof) that has type parameters, substitute
the type arguments for those type parameters. Similarly, substitute
into property accesses, instance variables, and other references.

This includes general infrastructure for substituting the type
arguments associated with an ObjCObject(Pointer)Type into a type
referenced within a particular context, handling all of the
substitutions required to deal with (e.g.) inheritance involving
parameterized classes. In cases where no type arguments are available
(e.g., because we're messaging via some unspecialized type, id, etc.),
we substitute in the type bounds for the type parameters instead.

Example:

  @interface NSSet<T : id<NSCopying>> : NSObject <NSCopying>
  - (T)firstObject;
  @end

  void f(NSSet<NSString *> *stringSet, NSSet *anySet) {
    [stringSet firstObject]; // produces NSString*
    [anySet firstObject]; // produces id<NSCopying> (the bound)
  }

When substituting for the type parameters given an unspecialized
context (i.e., no specific type arguments were given), substituting
the type bounds unconditionally produces type signatures that are too
strong compared to the pre-generics signatures. Instead, use the
following rule:

  - In covariant positions, such as method return types, replace type
    parameters with “id” or “Class” (the latter only when the type
    parameter bound is “Class” or qualified class, e.g,
    “Class<NSCopying>”)
  - In other positions (e.g., parameter types), replace type
    parameters with their type bounds.
  - When a specialized Objective-C object or object pointer type
    contains a type parameter in its type arguments (e.g.,
    NSArray<T>*, but not NSArray<NSString *> *), replace the entire
    object/object pointer type with its unspecialized version (e.g.,
    NSArray *).

Douglas Gregor e9d95f1ecc Handle Objective-C type arguments.
Objective-C type arguments can be provided in angle brackets following
an Objective-C interface type. Syntactically, this is the same
position as one would provide protocol qualifiers (e.g.,
id<NSCopying>), so parse both together and let Sema sort out the
ambiguous cases. This applies both when parsing types and when parsing
the superclass of an Objective-C class, which can now be a specialized
type (e.g., NSMutableArray<T> inherits from NSArray<T>).

Check Objective-C type arguments against the type parameters of the
corresponding class. Verify the length of the type argument list and
that each type argument satisfies the corresponding bound.

Specializations of parameterized Objective-C classes are represented
in the type system as distinct types. Both specialized types (e.g.,
NSArray<NSString *> *) and unspecialized types (NSArray *) are
represented, separately.

Douglas Gregor 85f3f9513d Parsing, semantic analysis, and AST for Objective-C type parameters.
Produce type parameter declarations for Objective-C type parameters,
and attach lists of type parameters to Objective-C classes,
categories, forward declarations, and extensions as
appropriate. Perform semantic analysis of type bounds for type
parameters, both in isolation and across classes/categories/extensions
to ensure consistency.

Also handle (de-)serialization of Objective-C type parameter lists,
along with sundry other things one must do to add a new declaration to
Clang.

Note that Objective-C type parameters are typedef name declarations,
like typedefs and C++11 type aliases, in support of type erasure.

Yunzhong Gao cb77930d6b Implementing C99 partial re-initialization behavior (DR-253)
Based on previous discussion on the mailing list, clang currently lacks support
for C99 partial re-initialization behavior:
Reference: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2013-April/029188.html
Reference: http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_253.htm

This patch attempts to fix this problem.

Given the following code snippet,

struct P1 { char x[6]; };
struct LP1 { struct P1 p1; };

struct LP1 l = { .p1 = { "foo" }, .p1.x[2] = 'x' };
// this example is adapted from the example for "struct fred x[]" in DR-253;
// currently clang produces in l: { "\0\0x" },
//   whereas gcc 4.8 produces { "fox" };
// with this fix, clang will also produce: { "fox" };

Ben Langmuir beee15e721 Allow multiple modules with the same name to coexist in the module cache
To differentiate between two modules with the same name, we will
consider the path the module map file that they are defined by* part of
the ‘key’ for looking up the precompiled module (pcm file).
Specifically, this patch renames the precompiled module (pcm) files from
  cache-path/<module hash>/Foo.pcm
to
  cache-path/<module hash>/Foo-<hash of module map path>.pcm

In addition, I’ve taught the ASTReader to re-resolve the names of
imported modules during module loading so that if the header search
context changes between when a module was originally built and when it
is loaded we can rebuild it if necessary.  For example, if module A
imports module B

first time:
clang -I /path/to/A -I /path/to/B ...

second time:
clang -I /path/to/A -I /different/path/to/B ...

will now rebuild A as expected.

* in the case of inferred modules, we use the module map file that
allowed the inference, not the __inferred_module.map file, since the
inferred file path is the same for every inferred module.

Stephan Tolksdorf e96f8b3774 Fix PR18806: Canonicalize the replacement type when deserializing a SubstTemplateTypeParmType
What's going on in the test case (without the patch applied) is this:

When the header is parsed, decltype(B()) is canonicalized to decltype(Y()),
because that was the first parsed equivalent decltype expression. Hence, the
TemplateSpecializationType for Id<decltype(B())> ends up with
SubstTemplateTypeParmType(T, decltype(Y())) as the AliasedType member.

When the PCH file is included and the AST reader reads Id<decltype(B())>, it
sees decltype(B()) before decltype(Y()). So, this time decltype(B()) ends up
being the canonical type for both decltypes, which leads to an assert violation
when the reader calls getSubstTemplateTypeParmType with the non-canonical
decltype(Y()) as the replacement type.

clang converts keywords to identifiers for compatibility with various system
headers such as GNU libc.

Implement a -Wkeyword-compat extension warning to diagnose those cases. The

can however be enabled globally to aid standards conformance testing.

This also changes the __uptr keyword avoidance from r195710 to no longer
special-case system headers, bringing it in line with other similar workarounds
in clang.

Implementation returns bool for symmetry with token annotation functions.

warning: keyword '__is_pod' will be treated as an identifier for the remainder of the translation unit [-Wkeyword-compat]
struct __is_pod

warning: keyword '__uptr' will be treated as an identifier here [-Wkeyword-compat]

Faisal Vali c1a6dc4907 Refactor out the circular reference to LambdaExpr in CXXRecordDecl.
A prior commit of this patch was reverted because it was within the blamelist's purview of a failing test.  The failure of that test has been addressed here: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20131021/091546.html.  Therefore I am recommitting this patch (all tests pass on windows, except for the usual modules & index suspects that never pass on my box).

Some background: Both Doug and Richard had asked me in Chicago to remove the circular reference in CXXRecordDecl to LambdaExpr by factoring out and storing the needed information from LambdaExpr directly into CXXRecordDecl.
 
In addition, I have added an IsGenericLambda flag - this makes life a little easier when we implement capturing, and are Sema-analyzing the body of a lambda (and the calloperator hasn't been wired to the closure class yet). Any inner lambdas can have potential captures that could require walking up the scope chain and checking if any generic lambdas are capture-ready. This 'bit' makes some of that checking easier. 

No change in functionality.

This patch was approved by Doug with minor modifications (comments were cleaned up, and all data members were converted from bool/enum to unsigned, as requested):

David Majnemer 766e259e38 Sema: Do not allow template declarations inside local classes
Summary:
Enforce the rule in C++11 [temp.mem]p2 that local classes cannot have
member templates.

This fixes PR16947.

N.B.  C++14 has slightly different wording to afford generic lambdas
declared inside of functions.

Fun fact:  Some formulations of local classes with member templates
would cause clang to crash during Itanium mangling, such as the
following:

void outer_mem() {
  struct Inner {
    template <typename = void>
    struct InnerTemplateClass {
      static void itc_mem() {}
    };
  };
  Inner::InnerTemplateClass<>::itc_mem();

Hal Finkel c4d7c82c7f Add the intrinsic __builtin_convertvector
LLVM supports applying conversion instructions to vectors of the same number of
elements (fptrunc, fptosi, etc.) but there had been no way for a Clang user to
cause such instructions to be generated when using builtin vector types.

C-style casting on vectors is already defined in terms of bitcasts, and so
cannot be used for these conversions as well (without leading to a very
confusing set of semantics). As a result, this adds a __builtin_convertvector
intrinsic (patterned after the OpenCL __builtin_astype intrinsic). This is
intended to aid the creation of vector intrinsic headers that create generic IR
instead of target-dependent intrinsics (in other words, this is a generic
_mm_cvtepi32_ps). As noted in the documentation, the action of
__builtin_convertvector is defined in terms of the action of a C-style cast on
each vector element.

Richard Smith 676c404dec Be lazier when loading KeyFunctions from PCH/modules. We don't need to load
these in eagerly if we're not actually processing a translation unit. The added
laziness here also avoids us loading in parts of a CXXRecordDecl earlier than an
upcoming class template specialization merging patch would like.

Ideally, we should mark the vtable as used when we see a definition for the key
function, rather than having a separate pass over dynamic classes at the end of
the TU. The existing approach is pretty bad for PCH/modules, since it forcibly
loads the declarations of all key functions in all imported modules, whether or

Faisal Vali 18d3598ed0 Fix PCH bug with member templates of local classes in nontemplate functions.
As noted by Richard in the post:
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130624/082605.html, the following code should not add an entry
into PendingLocalImplicitInstantiations, since local instantiations
should only occur within the context of other instantiations:

int foo(double y) {
   struct Lambda {
      template<class T> T operator()(T t) const { return t; };
   } lambda;
   return lambda(y);
}

Hence the attached code does the following:
  1) In MarkFunctionReferenced, check if ActiveInstantiations.size() 
      is non-zero before adding to PendingLocalImplicitInstantiations.
  2) In InstantiateFunctionDefinition, we swap out/in
      PendingLocalImplicitInstantiations so that only those 
      pending local instantiations that are added during the instantiation
      of the current function are instantiated recursively.

Argyrios Kyrtzidis dd7106375c When declaring an ObjC interface decl with a @compatibility_alias alias name, change the class name to the "real" one.
If we have something like

  @class NewImage;
  @compatibility_alias OldImage NewImage;
  @class OldImage;

the lookup for 'OldImage' will return the 'NewImage' decl ("@class NewImage").
In such a case, when creating the decl for "@class OldImage" use the real declaration name ("NewImage"),
instead of the alias one ("OldImage"), otherwise we will break IdentifierResolver and redecls-chain invariants.

Fixes crash of rdar://14112291.

Richard Smith 1d209d075b Fix bitcode desynchronization when loading a PCH containing a class template
specialization with modules enabled. Just don't merge them at all for now;
we'll revisit this when support for template merging is added.

In passing, make Decl::dump() a little safer to use with PCH/modules, by making
it not deserialize any additional declarations. From a debugger you can call
decls_begin() or similar first if you want to dump all child decls.

Richard Smith ba71c08523 First pass of semantic analysis for init-captures: check the initializer, build
a FieldDecl from it, and propagate both into the closure type and the
LambdaExpr.

You can't do much useful with them yet -- you can't use them within the body
of the lambda, because we don't have a representation for "the this of the
lambda, not the this of the enclosing context". We also don't have support or a
representation for a nested capture of an init-capture yet, which was intended
to work despite not being allowed by the current standard wording.

Andy Gibbs fcc699aee8 Extended VerifyDiagnosticConsumer to also verify source file for diagnostic.
VerifyDiagnosticConsumer previously would not check that the diagnostic and
its matching directive referenced the same source file.  Common practice was
to create directives that referenced other files but only by line number,
and this led to problems such as when the file containing the directive
didn't have enough lines to match the location of the diagnostic in the
other file, leading to bizarre file formatting and other oddities.

This patch causes VerifyDiagnosticConsumer to match source files as well as
line numbers.  Therefore, a new syntax is made available for directives, for
example:

// expected-error@file:line {{diagnostic message}}

This extends the @line feature where "file" is the file where the diagnostic
is generated.  The @line syntax is still available and uses the current file
for the diagnostic.  "file" can be specified either as a relative or absolute
path - although the latter has less usefulness, I think!  The #include search
paths will be used to locate the file and if it is not found an error will be
generated.

The new check is not optional: if the directive is in a different file to the
diagnostic, the file must be specified.  Therefore, a number of test-cases
have been updated with regard to this.

This closes out PR15613.
