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/VirtRegMap.cpp | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'lib/CodeGen/VirtRegMap.cpp') diff --git a/lib/CodeGen/VirtRegMap.cpp b/lib/CodeGen/VirtRegMap.cpp index df8a021d14..82c64f36d5 100644 --- a/lib/CodeGen/VirtRegMap.cpp +++ b/lib/CodeGen/VirtRegMap.cpp @@ -115,11 +115,10 @@ unsigned VirtRegMap::createSpillSlot(const TargetRegisterClass *RC) { unsigned VirtRegMap::getRegAllocPref(unsigned virtReg) { std::pair Hint = MRI->getRegAllocationHint(virtReg); unsigned physReg = Hint.second; - if (physReg && - TargetRegisterInfo::isVirtualRegister(physReg) && hasPhys(physReg)) + if (TargetRegisterInfo::isVirtualRegister(physReg) && hasPhys(physReg)) physReg = getPhys(physReg); if (Hint.first == 0) - return (physReg && TargetRegisterInfo::isPhysicalRegister(physReg)) + return (TargetRegisterInfo::isPhysicalRegister(physReg)) ? physReg : 0; return TRI->ResolveRegAllocHint(Hint.first, physReg, *MF); } -- cgit v1.2.3
