Emit @finally blocks completely lazily instead of forcing their

we would delete the catchall entry block, which would cause us to
delete the entry block of the finally cleanup as well because the
cleanup logic would merge the blocks, which in turn triggered an assert

entry.  Laziness turns out to be the most elegant solution to the problem.

13 years agoIntroduce a new AST node describing reference binding to temporaries.
Douglas Gregor [Tue, 21 Jun 2011 17:03:29 +0000 (17:03 +0000)]
Introduce a new AST node describing reference binding to temporaries.

MaterializeTemporaryExpr captures a reference binding to a temporary
value, making explicit that the temporary value (a prvalue) needs to
be materialized into memory so that its address can be used. The
intended AST invariant here is that a reference will always bind to a
glvalue, and MaterializeTemporaryExpr will be used to convert prvalues
into glvalues for that binding to happen. For example, given

  const int& r = 1.0;

The initializer of "r" will be a MaterializeTemporaryExpr whose
subexpression is an implicit conversion from the double literal "1.0"
to an integer value.

IR generation benefits most from this new node, since it was
previously guessing (badly) when to materialize temporaries for the
purposes of reference binding. There are likely more refactoring and
cleanups we could perform there, but the introduction of
MaterializeTemporaryExpr fixes PR9565, a case where IR generation
would effectively bind a const reference directly to a bitfield in a
struct. Addresses <rdar://problem/9552231>.

13 years agoAccept no-return stripping conversions for pointer type arguments after
Chandler Carruth [Sat, 18 Jun 2011 01:19:03 +0000 (01:19 +0000)]
Accept no-return stripping conversions for pointer type arguments after
deducing template parameter types. Recently Clang began enforcing the
more strict checking that the argument type and the deduced function
parameter type (after substitution) match, but that only consideres
qualification conversions.

One problem with this patch is that we check noreturn conversions and
qualification conversions independently. If a valid conversion would
require *both*, perhaps interleaved with each other, it will be
rejected. If this actually occurs (I'm not yet sure it does) and is in
fact a problem (I'm not yet sure it is), there is a FIXME to implement
more intelligent conversion checking.

However, this step at least allows Clang to resume accepting valid code
we're seeing in the wild.
