From ed90df38004678cf1ebf1caa3fbac8a0047be73e Mon Sep 17 00:00:00 2001 From: Douglas Gregor Date: Wed, 22 Feb 2012 05:02:47 +0000 Subject: Generate an AST for the conversion from a lambda closure type to a block pointer that returns a block literal which captures (by copy) the lambda closure itself. Some aspects of the block literal are left unspecified, namely the capture variable (which doesn't actually exist) and the body (which will be filled in by IRgen because it can't be written as an AST). Because we're switching to this model, this patch also eliminates tracking the copy-initialization expression for the block capture of the conversion function, since that information is now embedded in the synthesized block literal. -1 side tables FTW. llvm-svn: 151131 --- clang/lib/AST/Expr.cpp | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'clang/lib/AST/Expr.cpp') diff --git a/clang/lib/AST/Expr.cpp b/clang/lib/AST/Expr.cpp index 75c450867b5..f95ca173067 100644 --- a/clang/lib/AST/Expr.cpp +++ b/clang/lib/AST/Expr.cpp @@ -1076,6 +1076,11 @@ void CastExpr::CheckCastConsistency() const { !getSubExpr()->getType()->isBlockPointerType()); goto CheckNoBasePath; + case CK_CopyAndAutoreleaseBlockObject: + assert(getType()->isBlockPointerType()); + assert(getSubExpr()->getType()->isBlockPointerType()); + goto CheckNoBasePath; + // These should not have an inheritance path. case CK_Dynamic: case CK_ToUnion: @@ -1231,6 +1236,8 @@ const char *CastExpr::getCastKindName() const { return "AtomicToNonAtomic"; case CK_NonAtomicToAtomic: return "NonAtomicToAtomic"; + case CK_CopyAndAutoreleaseBlockObject: + return "CopyAndAutoreleaseBlockObject"; } llvm_unreachable("Unhandled cast kind!"); -- cgit v1.2.3
