From 67aec124091659f4e43fb0be67c07bb060763c19 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Wed, 11 Jan 2012 02:07:00 +0000 Subject: Exclusively use SplitAnalysis::getLastSplitPoint(). Delete the alternative implementation in LiveIntervalAnalysis. These functions computed the same thing, but SplitAnalysis caches the result. llvm-svn: 147911 --- llvm/lib/CodeGen/LiveIntervalAnalysis.cpp | 22 ---------------------- 1 file changed, 22 deletions(-) (limited to 'llvm/lib/CodeGen/LiveIntervalAnalysis.cpp') diff --git a/llvm/lib/CodeGen/LiveIntervalAnalysis.cpp b/llvm/lib/CodeGen/LiveIntervalAnalysis.cpp index 549e1a225a6..99ba0ecf499 100644 --- a/llvm/lib/CodeGen/LiveIntervalAnalysis.cpp +++ b/llvm/lib/CodeGen/LiveIntervalAnalysis.cpp @@ -779,28 +779,6 @@ bool LiveIntervals::shrinkToUses(LiveInterval *li, // Register allocator hooks. // -MachineBasicBlock::iterator -LiveIntervals::getLastSplitPoint(const LiveInterval &li, - MachineBasicBlock *mbb) const { - const MachineBasicBlock *lpad = mbb->getLandingPadSuccessor(); - - // If li is not live into a landing pad, we can insert spill code before the - // first terminator. - if (!lpad || !isLiveInToMBB(li, lpad)) - return mbb->getFirstTerminator(); - - // When there is a landing pad, spill code must go before the call instruction - // that can throw. - MachineBasicBlock::iterator I = mbb->end(), B = mbb->begin(); - while (I != B) { - --I; - if (I->isCall()) - return I; - } - // The block contains no calls that can throw, so use the first terminator. - return mbb->getFirstTerminator(); -} - void LiveIntervals::addKillFlags() { for (iterator I = begin(), E = end(); I != E; ++I) { unsigned Reg = I->first; -- cgit v1.2.3
