declarations after the member has been explicitly specialized. We already
did this after explicit instantiation definitions; not doing it for
declarations meant that subsequent definitions would see a previous
member declaration with specialization kind "explicit instantiation decl",
which would then happily get overridden.
Fixes PR 6458.

look into. Fixes PR6376.

propagating error conditions out of the various annotate-me-a-snowflake

as well as, you know, not crashing on bad code. On the other hand,
I have just signed myself up to fix fiddly parser errors for the next
week. Again.

This will also need CodeGen support. On a happy note, we're now a

Sema::ActOnUninitializedDecl over to InitializationSequence (with
default initialization), eliminating redundancy. More importantly, we
now check that a const definition in C++ has an initilizer, which was
an #if 0'd code for many, many months. A few other tweaks were needed
to get everything working again:
- Fix all of the places in the testsuite where we defined const
objects without initializers (now that we diagnose this issue)
- Teach instantiation of static data members to find the previous
declaration, so that we build proper redeclaration
chains. Previously, we had the redeclaration chain but built it
too late to be useful, because...
- Teach instantiation of static data member definitions not to try
to check an initializer if a previous declaration already had an
initializer. This makes sure that we don't complain about static
const data members with in-class initializers and out-of-line
definitions.
- Move all of the incomplete-type checking logic out of
Sema::FinalizeDeclaratorGroup; it makes more sense in
ActOnUnitializedDecl.
There may still be a few places where we can improve these
diagnostics. I'll address that as a separate commit.

- In C++, prior to the closing '}', set the type of enumerators
based on the type of their initializer. Don't perform unary
conversions on the enumerator values.
- In C++, handle overflow when an enumerator has no initializer and
its value cannot be represented in the type of the previous
enumerator.
- In C, handle overflow more gracefully, by complaining and then
falling back to the C++ rules.
- In C, if the enumerator value is representable in an int, convert the
expression to the type 'int'.
Fixes PR5854 and PR4515.

arguments. This both prevents meaningless checks on these arguments and ensures
that they are represented as an expression by the instantiation.
Cleaned up and added standard text to the relevant test case. Also started
adding tests for *rejected* cases. At least one FIXME here where (I think) we
allow something we shouldn't. More to come in the area of rejecting crazy
arguments with decent diagnostics. Suggestions welcome for still better
diagnostics on these errors!

(necessarily simultaneous) changes:
- CXXBaseOrMemberInitializer now contains only a single initializer
rather than a set of initialiation arguments + a constructor. The
single initializer covers all aspects of initialization, including
constructor calls as necessary but also cleanup of temporaries
created by the initializer (which we never handled
before!).
- Rework + simplify code generation for CXXBaseOrMemberInitializers,
since we can now just emit the initializer as an initializer.
- Switched base and member initialization over to the new
initialization code (InitializationSequence), so that it
- Improved diagnostics for the new initialization code when
initializing bases and members, to match the diagnostics produced
by the previous (special-purpose) code.
- Simplify the representation of type-checked constructor initializers in
templates; instead of keeping the fully-type-checked AST, which is
rather hard to undo at template instantiation time, throw away the
type-checked AST and store the raw expressions in the AST. This
simplifies instantiation, but loses a little but of information in
the AST.
- When type-checking implicit base or member initializers within a
dependent context, don't add the generated initializers into the
AST, because they'll look like they were explicit.
- Record in CXXConstructExpr when the constructor call is to
initialize a base class, so that CodeGen does not have to infer it
from context. This ensures that we call the right kind of
constructor.
There are also a few "opportunity" fixes here that were needed to not
regress, for example:
- Diagnose default-initialization of a const-qualified class that
does not have a user-declared default constructor. We had this
diagnostic specifically for bases and members, but missed it for
variables. That's fixed now.
- When defining the implicit constructors, destructor, and
copy-assignment operator, set the CurContext to that constructor
when we're defining the body.

that name constructors, the endless joys of out-of-line constructor
definitions, and various other corner cases that the previous hack
never imagined. Fixes PR5688 and tightens up semantic analysis for
constructor names.
Additionally, fixed a problem where we wouldn't properly enter the
declarator scope of a parenthesized declarator. We were entering the
scope, then leaving it when we saw the ")"; now, we re-enter the
declarator scope before parsing the parameter list.
Note that we are forced to perform some tentative parsing within a
class (call it C) to tell the difference between
C(int); // constructor
and
C (f)(int); // member function
which is rather unfortunate. And, although it isn't necessary for
correctness, we use the same tentative-parsing mechanism for
out-of-line constructors to improve diagnostics in icky cases like:
C::C C::f(int); // error: C::C refers to the constructor name, but
// we complain nicely and recover by treating it as
// a type.
llvm-svn: 93322
why the candidate is non-viable. There's a lot we can do to improve this, but
it's a good start. Further improvements should probably be integrated with the
bad-initialization reporting routines.
