Chain and address ptr remains as operands. SrcValue, extending mode, extending VT (or rather loaded VT before extension) are now instance variables of LoadSDNode. Introduce load / store addressing modes to represent pre- and post-indexed load and store. Also added an additional operand offset that is only used in post-indexed mode (i.e. base ptr += offset after load/store). Added alignment info (not yet used) and isVolatile fields. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30843 91177308-0d34-0410-b5e6-96231b3b80d8
