llvm-svn: 113817

Remove from the CFG the half-implemented support for scoping information.  We decided that scope information doesn't belong in the CFG at all, since it is a lexical construct.

Patch by Marcin Świderski!

llvm-svn: 113796

Remove CXXRecordDecl::getDefaultConstructor(), an inherently unsafe function due to lazy declaration of default constructors. Now that __has_nothrow_constructor doesn't use it anymore, part of PR8101 is fixed.

llvm-svn: 113794

Have __has_nothrow_copy use Sema's lookup routines. This fixes the problem with not finding implicitly declared copy constructors, part of PR8107.

llvm-svn: 113784

Eagerly evaluate type traits in Sema instead of lazily in AST. They actually need Sema access to be correct, fixes coming up.

llvm-svn: 113782

When applying 'delete' on a pointer-to-array type match GCC and EDG behavior and treat it as 'delete[]'.
Also offer a fix-it hint adding '[]'.

The canonical FunctionTemplateDecl contains the specializations but we cannot use getCanonicalDecl on Template because it may still be initializing.
Write and read it from PCH.

they were instantiated from a template. In template metaprogramming,
stuff happens. Fixes PR8065.

error to a warning if we're in a case that would be allowed in
C++0x. This "fixes" PR8084 by making Clang accept more code than GCC
and (non-strict) EDG do. 

Also, add the missing test case for the C++0x semantics, which should
have been in r113717.

llvm-svn: 113718

restrictions on out-of-line specializations to allow them anywhere in
an enclosing context. Motivated by PR8084.

Assigning an underlying integral type to an enum forward declaration will come in a next patch.

declarations in potentially-evaluated subexpressions, about
recursion. Fixes the release-mode self-host failure I introduced in
r113700.

llvm-svn: 113705

used in the default function argument as "used". Instead, when we
actually use the default argument, make another pass over the
expression to mark any used declarations as "used" at that point. This
addresses two kinds of related problems:

  1) We were marking some declarations "used" that shouldn't be,
  because we were marking them too eagerly.
  2) We were failing to mark some declarations as "used" when we
  should, if the first time it was instantiated happened to be an
  unevaluated context, we wouldn't mark them again at a later point.

I've also added a potentially-handy visitor class template
EvaluatedExprVisitor, which only visits the potentially-evaluated
subexpressions of an expression. I bet this would have been useful for
noexcept...

Fixes PR5810 and PR8127.

llvm-svn: 113700

preambles end up leaving the precompiled preambles around. This is by
design, since we do minimal cleanup during crash recovery. However,
it's unfortunate for testing, so introduce a hook that allows these
two tests to put the precompiled preamble somewhere where we can
delete them after testing.

llvm-svn: 113698

just abort creation of the precompiled preamble rather than doing
silly things. This is the second part of the fix for the weird
preamble-related failures on Windows. Big thanks to Francois Pichet
for the great detective work!

which the precompiled preamble will reside before creating the
temporary file itself.
