From c134395628c82d176d249958a6660c06143558f7 Mon Sep 17 00:00:00 2001 From: Brian Gaeke Date: Mon, 23 Feb 2004 18:16:10 +0000 Subject: [PATCH] Renamed from include/Support/iterator. Doxygenify comments; add autoconf substitution tags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11754 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/Support/iterator.in | 66 ++++++++++++++++++++++++++++++++++++ include/llvm/ADT/iterator.in | 66 ++++++++++++++++++++++++++++++++++++ 2 files changed, 132 insertions(+) create mode 100644 include/Support/iterator.in create mode 100644 include/llvm/ADT/iterator.in diff --git a/include/Support/iterator.in b/include/Support/iterator.in new file mode 100644 index 00000000000..93813e19859 --- /dev/null +++ b/include/Support/iterator.in @@ -0,0 +1,66 @@ +//===-- Support/iterator - "Portable" wrapper around -*- C++ -*-===// +// +// The LLVM Compiler Infrastructure +// +// This file was developed by the LLVM research group and is distributed under +// the University of Illinois Open Source License.
