From d4771828caa4e3a0403cb32e6b1c6c96ffa41830 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Wed, 18 Mar 2009 20:36:45 +0000 Subject: [PATCH] include the null at the end of a memorybuffer as part of the buffer. This allows tblgen to handle include "foo.td" when the quote is exactly the last character in a file. rdar://6695728 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67232 91177308-0d34-0410-b5e6-96231b3b80d8 --- utils/TableGen/TGSourceMgr.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/utils/TableGen/TGSourceMgr.cpp b/utils/TableGen/TGSourceMgr.cpp index 9c39230def2..e4d1c40dc6c 100644 --- a/utils/TableGen/TGSourceMgr.cpp +++ b/utils/TableGen/TGSourceMgr.cpp @@ -28,7 +28,9 @@ TGSourceMgr::~TGSourceMgr() { int TGSourceMgr::FindBufferContainingLoc(TGLoc Loc) const { for (unsigned i = 0, e = Buffers.size(); i != e; ++i) if (Loc.getPointer() >= Buffers[i].Buffer->getBufferStart() && - Loc.getPointer() < Buffers[i].Buffer->getBufferEnd()) + // Use <= here so that a pointer to the null at the end of the buffer + // is included as part of the buffer. + Loc.getPointer() <= Buffers[i].Buffer->getBufferEnd()) return i; return -1; }
