...mplification passes are: * Calling conventions lowering: ExpandVarArgs and ExpandByVal lower varargs and by-value argument passing respectively. They would be useful for any backend that doesn't want to implement varargs or by-value calling conventions. * Instruction-level lowering: * ExpandStructRegs splits up struct values into scalars, removing the "insertvalue" and "extractvalue" instructions. * PromoteIntegers legalizes integer types (e.g. i30 is converted to i32). * Module-level lowering: This implements, at the IR level, functionality that is traditionally prov...
