TenDRA Compiler

The TenDRA Compiler is a C/C++ compiler for POSIX-compatible operating systems available under the terms of the BSD license.

It was originally developed by the Defence Evaluation and Research Agency (DERA) in the United Kingdom . In the beginning of 2002 TenDRA was actively developed again by Jeroen Ruigrok van der Werven and offered as a BSD-licensed open source project through the website tendra.org. In the third quarter of 2002 the one-man effort was expanded to a small team.

The TDF technology behind TenDRA has an academic history dating back to work on algebraic code validation in the 1970s.^[1]

In August 2003 TenDRA split into two projects, TenDRA.org and Ten15.org. Both projects seemed to have disappeared from the web around 2006–2007, but actually they are still active.^[2][3]

The goals of TenDRA.org are:^{[citation needed]}

• to continuously produce correct code,
• to ensure code correctness through various means, and
• to continuously improve the performance of the compiler and resulting code, unless it would jeopardize the points above.

The goals of Ten15.org added:^{[citation needed]}

• to be a friendly competitor to GCC in order to get a best-of-breed compiler.

Features of both compilers include good error reporting with respect to standards compliance and a smaller code size than the same programs compiled on gcc. C++ support never got as developed as C support, and there was no STL supporting release. TenDRA uses the Architecture Neutral Distribution Format (ANDF), a specification created by the Open Group, as its intermediate language.

At a point, most of the Alpha OSF/1 kernel could be built with TenDRA C and afterwards there was also a similar effort to port the FreeBSD kernel.
