U-Code(ID:875/uco001)

Universal P-Code 

for Universal Code

Intermediate language, a generalization of UCSD P-code for easier optimization.

Developed originally for the Los Alamos Cray-1 and the Lawrence Livermore S-1.

A refined version currently used by MIPS compilers is descended from one at Stanford U.

This new language, Universal pseudo-code, is designed to be easily extended to meet the needs of a variety of target machines. The language is further designed such that only one optimizer need be written for it. This approach lends itself well to the portable software spirit of PASCAL. The problems and opportunities associated with optimization at this level are discussed.
