From 859a18b5833f3566799313ecba8db4916500485b Mon Sep 17 00:00:00 2001 From: Alkis Evlogimenos Date: Sun, 15 Feb 2004 21:37:17 +0000 Subject: Make dense maps keyed on physical registers smallerusing MRegisterInfo::getNumRegs() instead of MRegisterInfo::FirstVirtualRegister. Also use MRegisterInfo::is{Physical,Virtual}Register where appropriate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11477 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/LiveVariables.cpp | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'lib/CodeGen/LiveVariables.cpp') diff --git a/lib/CodeGen/LiveVariables.cpp b/lib/CodeGen/LiveVariables.cpp index 420cb4443e..0554bae87b 100644 --- a/lib/CodeGen/LiveVariables.cpp +++ b/lib/CodeGen/LiveVariables.cpp @@ -187,10 +187,9 @@ bool LiveVariables::runOnMachineFunction(MachineFunction &MF) { // physical register.
