From 84bc5427d6883f73cfeae3da640acd011d35c006 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 31 Dec 2007 04:13:23 +0000 Subject: Rename SSARegMap -> MachineRegisterInfo in keeping with the idea that "machine" classes are used to represent the current state of the code being compiled. Given this expanded name, we can start moving other stuff into it. For now, move the UsedPhysRegs and LiveIn/LoveOuts vectors from MachineFunction into it. Update all the clients to match. This also reduces some needless #includes, such as MachineModuleInfo from MachineFunction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45467 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/MachineRegisterInfo.cpp | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) create mode 100644 lib/CodeGen/MachineRegisterInfo.cpp (limited to 'lib/CodeGen/MachineRegisterInfo.cpp') diff --git a/lib/CodeGen/MachineRegisterInfo.cpp b/lib/CodeGen/MachineRegisterInfo.cpp new file mode 100644 index 0000000000..19c09eee51 --- /dev/null +++ b/lib/CodeGen/MachineRegisterInfo.cpp @@ -0,0 +1,20 @@ +//===-- MachineRegisterInfo.cpp -------------------------------------------===// +// +// The LLVM Compiler Infrastructure +// +// This file is distributed under the University of Illinois Open Source +// License.
