From 175143bf88e65fa87d7b4367829d4854f0e1a986 Mon Sep 17 00:00:00 2001 From: Andrew Trick Date: Sat, 25 May 2013 02:20:36 +0000 Subject: Track IR ordering of SelectionDAG nodes 1/4. Use a field in the SelectionDAGNode object to track its IR ordering. This adds fields and utility classes without changing existing interfaces or functionality. llvm-svn: 182701 --- llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.h | 16 ++++++++++++---- 1 file changed, 12 insertions(+), 4 deletions(-) (limited to 'llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.h') diff --git a/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.h b/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.h index 9188945bd90..6d356941b2d 100644 --- a/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.h +++ b/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.h @@ -80,8 +80,8 @@ class ZExtInst; /// implementation that is parameterized by a TargetLowering object. /// class SelectionDAGBuilder { - /// CurDebugLoc - current file + line number.
