them as machine instructions. Directives ".set noat" and ".set at" are now emitted only at the beginning and end of a function except in the case where they are emitted to enclose .cpload with an immediate operand that doesn't fit in 16-bit field or unaligned load/stores. Also, make the following changes: - Remove function isUnalignedLoadStore and use a switch-case statement to determine whether an instruction is an unaligned load or store. - Define helper function CreateMCInst which generates an instance of an MCInst from an opcode and a list of operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153552 91177308-0d34-0410-b5e6-96231b3b80d8
