From 09fd736058ec3f69b856ae3ad65177bc31904a8c Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Wed, 2 Aug 2006 21:58:44 +0000 Subject: [PATCH] AssignTopologicalOrder now returns the vector of SDNode* by reference to avoid the expensive operation of copying a vector. It also returns a maximum id by value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29478 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/CodeGen/SelectionDAG.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/include/llvm/CodeGen/SelectionDAG.h b/include/llvm/CodeGen/SelectionDAG.h index b7dda01a0a1..b053a3c25aa 100644 --- a/include/llvm/CodeGen/SelectionDAG.h +++ b/include/llvm/CodeGen/SelectionDAG.h @@ -427,9 +427,9 @@ public: unsigned AssignNodeIds(); /// AssignTopologicalOrder - Assign a unique node id for each node in the DAG - /// based on their topological order.
