From b18d779b35909cd5b753871f8bf2ff4f6c17ace1 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Fri, 27 Jul 2012 21:11:14 +0000 Subject: Eliminate the IS_PHI_DEF flag and VNInfo::setIsPHIDef(). A value number is a PHI def if and only if it begins at a block boundary. This can be derived from the def slot, a separate flag is not necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160893 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/LiveRangeCalc.cpp | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'lib/CodeGen/LiveRangeCalc.cpp') diff --git a/lib/CodeGen/LiveRangeCalc.cpp b/lib/CodeGen/LiveRangeCalc.cpp index 9384075ece..d828f25932 100644 --- a/lib/CodeGen/LiveRangeCalc.cpp +++ b/lib/CodeGen/LiveRangeCalc.cpp @@ -54,8 +54,7 @@ void LiveRangeCalc::createDeadDefs(LiveInterval *LI, unsigned Reg) { .getRegSlot(I.getOperand().isEarlyClobber()); // Create the def in LI.
