Design of a checkout compiler
B. L. Marks · IBM Systems Journal · 1973
The Checkout Compiler was developed to work in harness with the Optimizing Compiler to provide an exceptional level of support for the PL/I language. The Checkout Compiler was designed particularly to increase the productivity of programmers in their development of programs. In meeting this objective, certain constraints had to be taken into consideration, chief of these being compatibility with the Optimizing Compiler. Some design choices were made for performance reasons.
