For two decades, large parts of zSeries firmware have been written in the PL8 programming language. The existence of a large amount of mature zSeries firmware source code and our excellent experience with PL8 for system programming suggest keeping this language. However, the firmware address space of today's zSeries servers may exceed 2 GB, raising the need for a new 64-bit PL8 compiler, since the original implementation, developed at the IBM Thomas J. Watson Research Center, Yorktown Heights, New York, supports only 32-bit platforms. This paper reports on the extension of PL8 to support 64-bit addressing, its implementation as a GCC front end, and the validation of the new compiler.
