From a8dab36f3dfdfcd3f74224afa4ffb32776674c93 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Sat, 10 Jul 2010 22:42:31 +0000 Subject: Fix a bug in the code which re-inserts DBG_VALUE nodes after scheduling; if a block is split (by a custom inserter), the insert point may be in a different block than it was originally. This fixes 32-bit llvm-gcc bootstrap builds, and I haven't been able to reproduce it otherwise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108060 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/SelectionDAG/ScheduleDAGSDNodes.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'lib/CodeGen/SelectionDAG/ScheduleDAGSDNodes.cpp') diff --git a/lib/CodeGen/SelectionDAG/ScheduleDAGSDNodes.cpp b/lib/CodeGen/SelectionDAG/ScheduleDAGSDNodes.cpp index 2673eba..06cf053 100644 --- a/lib/CodeGen/SelectionDAG/ScheduleDAGSDNodes.cpp +++ b/lib/CodeGen/SelectionDAG/ScheduleDAGSDNodes.cpp @@ -642,8 +642,10 @@ MachineBasicBlock *ScheduleDAGSDNodes::EmitSchedule() { // Insert to start of the BB (after PHIs).
