- Use MipsAnalyzeImmediate to expand immediates that do not fit in 16-bit. - Change the types of variables so that they are sufficiently large to handle 64-bit pointers. - Emit instructions to set register $28 in a function prologue after instructions which store callee-saved registers have been emitted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148917 91177308-0d34-0410-b5e6-96231b3b80d8
