From c9df025e33ac435adb3b3318d237c36ca7cec659 Mon Sep 17 00:00:00 2001 From: Jakob Stoklund Olesen Date: Mon, 10 Jan 2011 02:58:51 +0000 Subject: Simplify a bunch of isVirtualRegister() and isPhysicalRegister() logic. These functions not longer assert when passed 0, but simply return false instead. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123155 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/RegAllocLinearScan.cpp | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'lib/CodeGen/RegAllocLinearScan.cpp') diff --git a/lib/CodeGen/RegAllocLinearScan.cpp b/lib/CodeGen/RegAllocLinearScan.cpp index bbff424710..14f672666d 100644 --- a/lib/CodeGen/RegAllocLinearScan.cpp +++ b/lib/CodeGen/RegAllocLinearScan.cpp @@ -1421,8 +1421,7 @@ unsigned RALinScan::getFreePhysReg(LiveInterval* cur, std::pair Hint = mri_->getRegAllocationHint(cur->reg); // Resolve second part of the hint (if possible) given the current allocation. unsigned physReg = Hint.second; - if (physReg && - TargetRegisterInfo::isVirtualRegister(physReg) && vrm_->hasPhys(physReg)) + if (TargetRegisterInfo::isVirtualRegister(physReg) && vrm_->hasPhys(physReg)) physReg = vrm_->getPhys(physReg); TargetRegisterClass::iterator I, E; -- cgit v1.2.3-18-g5258
