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.[1]

Norcroft C was developed by Codemist, established in November 1987[2] by a group of academics from the University of Cambridge and University of Bath;[3][4]Arthur Norman, Alan Mycroft and John Fitch. Development took place from at least 1985;[5][6] the company was dissolved in May 2016.[2] The name Norcroft is derived from the original authors' surnames.[7]

Supported architectures

Acorn C/C++

Acorn C/C++ was released for the RISC OS operating system, developed in collaboration with Acorn Computers.[1][8]

INMOS Transputer C Compiler

This compiler for the INMOS Transputer was developed in collaboration with Perihelion Software.[8]

Cambridge Consultants XAP

This compiler for Cambridge Consultants' XAP processor is another Norcroft compiler.[8]

C release 3 was made in 1989, and was followed by Desktop C and Desktop Assembler in 1991. The development of the compiler was a joint venture between Norcroft (at the time Arthur Norman and Alan Mycroft--two academics from Cambridge University Computing Labs) and the PLG at Acorn. Sources were regularly exchanged between both parties but, generally, Norcroft were responsible for adherence to the emerging ANSI standard, whilst Acorn concentrated on the RISC OS specifics of the C library and on common subexpression elimination, register allocation and peephole optimisation for the ARM.CS1 maint: postscript (link)
