From a25dfd2963070303bc17c7f55bf429a9b0f1d667 Mon Sep 17 00:00:00 2001 From: Jim Laskey Date: Tue, 25 Jul 2006 23:22:00 +0000 Subject: Moving this function to a permanent home to prevent a dependency cycle created by the inline heuristic. Was preventing llvm-gcc4 from building. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29278 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/VMCore/Type.cpp | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'lib/VMCore/Type.cpp') diff --git a/lib/VMCore/Type.cpp b/lib/VMCore/Type.cpp index a393556..1fdec94 100644 --- a/lib/VMCore/Type.cpp +++ b/lib/VMCore/Type.cpp @@ -33,6 +33,25 @@ using namespace llvm; AbstractTypeUser::~AbstractTypeUser() {} + +//===----------------------------------------------------------------------===// +// Type PATypeHolder Implementation +//===----------------------------------------------------------------------===// + +// This routine was moved here to resolve a cyclic dependency caused by +// inline heuristics. + +/// get - This implements the forwarding part of the union-find algorithm for +/// abstract types.
