Norcroft C compiler
The Norcroft C compiler (also referred to as the Norcroft compiler suite) in computing is a portable set of C/C++ programming tools written by Codemist, available for a wide range of processor architectures. Norcroft C was developed by Codemist, established in November 1987 by a group of academics from the University of Cambridge and University of Bath; Arthur Norman, Alan Mycroft and John Fitch. Development took place from at least 1985; the company was dissolved in May 2016. The name Norcroft is derived from the original authors' surnames. Supported architectures
