-fno-constant-cfstrings. Patch by Jonathan Schleifer.

'true' on detecting protocol cycles. No functionality change.

llvm-svn: 131297

One more special member to go

llvm-svn: 131287

This introduces a generic base class for the expression evaluator
classes, which handles a few common expression types which were
previously handled separately in each class.  Also, the expression
evaluator now uses ConstStmtVisitor.

llvm-svn: 131278

constant, also consider whether it's a class type that has any mutable
fields. If so, it can't be a global constant.

llvm-svn: 131276

template parameter lists to scope specifiers for friend declarations
about injected class name types. Fixes the
g++.dg/template/memfriend5.C regression in the GCC testsuite.

correct unaligned load.

don't build circular AST in protocol's protocol list 
when user code has introduced it. Indexer and other   
clients may crash. // rdar://9221614

which produces really bad code. This could be done in instcombine, but it's
probably better to do it in the front-end instead.

They are actually grammatically considered definitions and parsed
accordingly.

This fixes the outstanding bugs regarding defaulting functions after
their declarations.

We now really nicely diagnose the following construct (try it!)

int foo() = delete, bar;

Still todo: Defaulted functions other than default constructors
            Test cases (including for the above construct)

llvm-svn: 131228

defaulted default constructors.

As it happens, making sure that we handle out-of-line defaulted
functions properly will involved making sure that we actually parse them
correctly, so that's coming after.

llvm-svn: 131224

We still don't parse out-of-line defaults correctly, which is needed to
get the full effect out of this patch.

llvm-svn: 131212

Fix PR9902: correctly substitute alias templates within the template in which they are defined: provide an empty list of arguments for each containing template context during substitution.

llvm-svn: 131211

argument deduction failures. Only implemented in C++0x, since this is
a significant change in behavior from C++98/03.

llvm-svn: 131209

nested of an out-of-line declaration, only require a 'template<>'
header for each enclosing class template that hasn't been previously
specialized; previously, we were requiring 'template<>' for enclosing
class templates and members of class templates that hadn't been
previously specialized. Fixes <rdar://problem/9422013>.

llvm-svn: 131207

This means we get C++0x jump-across-intializer semantics correct.

llvm-svn: 131204

Yes, I'm aware that the diagnostics are awful.

Tests to follow.

llvm-svn: 131203

In Microsoft mode, allow conversion from pointer to integral type no matter what size the integral type is. Necessary to parse MFC code.

Example:
void f(char *ptr) {
  char var = (char)ptr;
}

llvm-svn: 131201

then teach -Wreturn-type to handle the same.  Net effect:  we now correctly
handle noreturn attributes on member calls in the CFG.

llvm-svn: 131178

dynamic_cast correctly.

llvm-svn: 131177

This removes 2 errors when parsing MFC code with clang

Example:
class A {
    virtual void f() = 0 { }
}

llvm-svn: 131175

llvm-svn: 131170

llvm-svn: 131158

I've edited one diagnostic which would print "copy constructor" for copy
constructors and "constructor" for any other constructor. If anyone is
extremely enamored with this, it can be reinstated with a simple boolean
flag rather than calling getSpecialMember, which is inappropriate.

llvm-svn: 131143

llvm-svn: 131142

Elide __label__ declarations from the CFG.  This resolves a crash in CFGRecStmtDeclVisitor (crash in static analyzer).

llvm-svn: 131141

the semantic context referenced by the nested-name-specifier rather
than the syntactic form of the nested-name-specifier. The previous
incarnation was based on my complete misunderstanding of C++
[temp.expl.spec]. The latest C++0x working draft clarifies the
requirements here, and this rewrite is intended to follow that.

Along the way, improve source location information in the
diagnostics. For example, if we report that a specific type needs or
doesn't need a 'template<>' header, we dig out that type in the
nested-name-specifier and highlight its range.

Fixes: PR5907, PR9421, PR8277, PR8708, PR9482, PR9668, PR9877, and
<rdar://problem/9135379>.
