The Norcroft compiler can be used to produce {{nowrap|RISC OS}} [[software module|module]]s, as well as compiling parts of the [[operating system]] itself.

The suite of tools is currently the only means of building a working copy of {{nowrap|RISC OS}}, although it is ultimately intended that this will also be possible using a [[cross compiler]], e.g. using the [[free software]] [[GCC (software)|GCC]] system.<ref name="riscosopen cross compilation support">{{cite web | url=http://www.riscosopen.org/forum/forums/3/topics/394#posts-3539 | title=Cross compilation support | publisher=[[RISC OS Open]] | date=2010-05-20 | accessdate=October 21, 2011 | author=Avison, Ben | quote=[...] the completion of Pace’s cross-compilation project – an initial milestone on the path to full cross-compilation support.

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]
Codemist was established and run by a group of academics from the University of Cambridge and University of Bath.[2][3] The name Norcroft is derived from the authors' surnames, Norman and Mycroft.[4]
Supported architectures
Acorn C/C++
This compiler for the RISC OS operating system was developed in collaboration with Acorn Computers[1][5] and released as Acorn C/C++.
INMOS Transputer C Compiler
This compiler for the INMOS Transputer was developed in collaboration with Perihelion Software.[5]
Cambridge Consultants XAP
This compiler for Cambridge Consultants' XAP processor is another Norcroft compiler.[5]

Acorn began work on ANSI C compilers around 1987. 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.
