From 864e2efce2cb5d02e376933933d96074723fe77c Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Sat, 5 Dec 2009 00:44:40 +0000 Subject: Remove the target hook TargetInstrInfo::BlockHasNoFallThrough in favor of MachineBasicBlock::canFallThrough(), which is target-independent and more thorough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90634 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/SystemZ/SystemZInstrInfo.cpp | 12 ------------ lib/Target/SystemZ/SystemZInstrInfo.h | 1 - 2 files changed, 13 deletions(-) (limited to 'lib/Target/SystemZ') diff --git a/lib/Target/SystemZ/SystemZInstrInfo.cpp b/lib/Target/SystemZ/SystemZInstrInfo.cpp index d711d81..5fa7e8c 100644 --- a/lib/Target/SystemZ/SystemZInstrInfo.cpp +++ b/lib/Target/SystemZ/SystemZInstrInfo.cpp @@ -402,18 +402,6 @@ ReverseBranchCondition(SmallVectorImpl &Cond) const { return false; } -bool SystemZInstrInfo::BlockHasNoFallThrough(const MachineBasicBlock &MBB)const{ - if (MBB.empty()) return false; - - switch (MBB.back().getOpcode()) { - case SystemZ::RET: // Return. - case SystemZ::JMP: // Uncond branch. - case SystemZ::JMPr: // Indirect branch. - return true; - default: return false; - } -} - bool SystemZInstrInfo::isUnpredicatedTerminator(const MachineInstr *MI) const { const TargetInstrDesc &TID = MI->getDesc(); if (!TID.isTerminator()) return false; diff --git a/lib/Target/SystemZ/SystemZInstrInfo.h b/lib/Target/SystemZ/SystemZInstrInfo.h index e16d704..ef3b39e 100644 --- a/lib/Target/SystemZ/SystemZInstrInfo.h +++ b/lib/Target/SystemZ/SystemZInstrInfo.h @@ -89,7 +89,6 @@ public: const std::vector &CSI) const; bool ReverseBranchCondition(SmallVectorImpl &Cond) const; - virtual bool BlockHasNoFallThrough(const MachineBasicBlock &MBB) const; virtual bool isUnpredicatedTerminator(const MachineInstr *MI) const; virtual bool AnalyzeBranch(MachineBasicBlock &MBB, MachineBasicBlock *&TBB, -- cgit v1.1
