Abstract: | This paper describes an experimental evaluation of the execution speed of object programs produced by six PL/I compilers. A set of 139 representative PL/I statements were compiled and executed under the PL/I Optimizing, PL/I(F), PL/C, PL/I Checkout, SP/k and PLUTO compilers. An analysis is made of the relative speed of the object code produced by each compiler and also of the relative execution speed of each statement. |
