behind implicit moves. We now correctly identify move constructors and
assignment operators and update bits on the record correctly. Generation
of implicit moves (declarations or definitions) is not yet supported.

Patch by Matthieu Monrocq with tweaks by me to avoid StringRefs in the static
diagnostic data structures, which resulted in a huge global-var-init function.
Depends on llvm commit r132046.

type that turns one type into another. This is used as the basis to
implement __underlying_type properly - with TypeSourceInfo and proper
behavior in the face of templates.

that the unevaluated subexpressions of &&, ||, and ? : are not
considered when determining whether the expression is a constant
expression. Also, turn the "used in its own initializer" warning into
a runtime-behavior warning, so that it doesn't fire when a variable is
used as part of an unevaluated subexpression of its own initializer.
Fixes PR9999.

through sugared types when testing for TagTypes. This was the actual
cause of the only false positive in Clang+LLVM.
Next evaluation will be over a much larger selection of code including
large amounts of open source code.

issues and also add a test.
We should now handle defaulted members of templates properly. No
comment as to whether or not this also holds for templated functions,
but defaulting those is kind of insane.

The general out-of-line case (including explicit instantiation mostly
works except that the definition is being lost somewhere between the AST
and CodeGen, so the definition is never emitted.
llvm-svn: 131933
fixes PR9965, but we're not out of the water yet, as we do not
successfully handle out-of-line definitions, due to my utter
misunderstanding of how we manage templates.

Example:
class A { public: int f(); };
class B : public A { private: using A::f; };
class C : public B { private: using B::f; };
Here, B::f is private so this should fail in Standard C++, but because B::f refers to A::f which is public MSVC accepts it.
This fixes 1 error when parsing MFC code with clang.

generator will give it something sufficient. This is important because
the mid-level optimizer doesn't know what alignment is required otherwise.

header. Getting it in the wrong order generated incorrect line markers in -E
mode. In the testcase from PR9861 we used to generate:
# 1 "test.c" 2
# 1 "./foobar.h" 1
# 0 "./foobar.h"
# 0 "./foobar.h" 3
# 2 "test.c" 2
now we properly produce:
# 1 "test.c" 2
# 1 "./foobar.h" 1
# 1 "./foobar.h" 3
# 2 "test.c" 2
This fixes PR9861.

to determine outer template arguments lists for template
parameters. This is actually the problem behind PR9643, which I have
yet to figure out how to fix.
llvm-svn: 131822
minor issues along the way:
- Non-type template parameters of type 'std::nullptr_t' were not
permitted.
- We didn't properly introduce built-in operators for nullptr ==,
!=, <, <=, >=, or > as candidate functions .
To my knowledge, there's only one (minor but annoying) part of nullptr
that hasn't been implemented: catching a thrown 'nullptr' as a pointer
or pointer-to-member, per C++0x [except.handle]p4.

non-POD/non-trivial object throuugh a C-style varargs. The warning
itself was default-mapped to error, but can be downgraded, but we were
treating it in Sema like a hard error, silently dropping the call.
Instead, treat this problem like a warning, and do what the warning
says we do: abort at runtime. To do so, we fake up a __builtin_trap()
expression that gets evaluated as part of the argument.

should use a constructor to default-initialize a
variable. InitializationSequence knows the rules for default
initialization, better. Fixes <rdar://problem/8501008>.

prints the file, line, and column of a diagnostic. We currently
support Clang's normal format, MSVC, and Vi formats.
Note that we no longer change the diagnostic format based on
-fms-extensions.
