From af9fa2bd0c1ee25f3adda96b3e5d7129fbab393a Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Thu, 2 Feb 2006 20:11:55 +0000 Subject: [PATCH] Move isLoadFrom/StoreToStackSlot from MRegisterInfo to TargetInstrInfo, a far more logical place. Other methods should also be moved if anyone is interested. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@25912 91177308-0d34-0410-b5e6-96231b3b80d8 --- include/llvm/Target/MRegisterInfo.h | 18 ------------------ include/llvm/Target/TargetInstrInfo.h | 18 ++++++++++++++++++ 2 files changed, 18 insertions(+), 18 deletions(-) diff --git a/include/llvm/Target/MRegisterInfo.h b/include/llvm/Target/MRegisterInfo.h index 67c118d5a85..99d2929a018 100644 --- a/include/llvm/Target/MRegisterInfo.h +++ b/include/llvm/Target/MRegisterInfo.h @@ -259,24 +259,6 @@ public: unsigned DestReg, unsigned SrcReg, const TargetRegisterClass *RC) const = 0; - /// isLoadFromStackSlot - If the specified machine instruction is a direct - /// load from a stack slot, return the virtual or physical register number of - /// the destination along with the FrameIndex of the loaded stack slot.
