From 76604af7748badc535017534f5f4c627516fdd7a Mon Sep 17 00:00:00 2001 From: Owen Anderson Date: Thu, 13 Mar 2014 06:02:25 +0000 Subject: Phase 1 of refactoring the MachineRegisterInfo iterators to make them suitable for use with C++11 range-based for-loops. The gist of phase 1 is to remove the skipInstruction() and skipBundle() methods from these iterators, instead splitting each iterator into a version that walks operands, a version that walks instructions, and a version that walks bundles. This has the result of making some "clever" loops in lib/CodeGen more verbose, but also makes their iterator invalidation characteristics much more obvious to the casual reader. (Making them concise again in the future is a good motivating case for a pre-incrementing range adapter!) Phase 2 of this undertaking with consist of removing the getOperand() method, and changing operator*() of the operand-walker to return a MachineOperand&. At that point, it should be possible to add range views for them that work as one might expect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@203757 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/RegisterPressure.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'lib/CodeGen/RegisterPressure.cpp') diff --git a/lib/CodeGen/RegisterPressure.cpp b/lib/CodeGen/RegisterPressure.cpp index cfeafbf403..97817daac5 100644 --- a/lib/CodeGen/RegisterPressure.cpp +++ b/lib/CodeGen/RegisterPressure.cpp @@ -882,9 +882,9 @@ static bool findUseBetween(unsigned Reg, SlotIndex PriorUseIdx, SlotIndex NextUseIdx, const MachineRegisterInfo *MRI, const LiveIntervals *LIS) { - for (MachineRegisterInfo::use_nodbg_iterator - UI = MRI->use_nodbg_begin(Reg), UE = MRI->use_nodbg_end(); - UI != UE; UI.skipInstruction()) { + for (MachineRegisterInfo::use_instr_nodbg_iterator + UI = MRI->use_instr_nodbg_begin(Reg), + UE = MRI->use_instr_nodbg_end(); UI != UE; ++UI) { const MachineInstr* MI = &*UI; if (MI->isDebugValue()) continue; -- cgit v1.2.3
