Dinechin contributed to C++, notably a high-performance exception handling implementationcite-ref-1[1] that became a de-facto standard in the industry.cite-ref-2[2] de Dinechin was one of the proponents of a portable C++ ABI, initially developed for Itanium, but now widely used across platforms.cite-ref-3[3]

Dinechin is the designer of the XL programming language and associated concept programming methodology.cite-ref-4[4] "XL" is named for "eXtensible Language".

XL features programmer-reconfigurable syntax and semantics. Compiler plug-ins can be used to add new features to the language. A base set of plug-ins implements a relatively standard imperative language. Programmers can write their own plug-ins to implement application-specific notations, such as symbolic differentiation, which can then be used as readily as built-in language features.

There are projects that exploit similar ideas to create code with higher level of abstraction. Among them are:

• Language-oriented programming

• Literate programming

• Model-driven architecture

As initial developer of Alpha Waves, a "groundbreaking" Atari ST game (listed in the Guinness World Records as the first 3D platform gamecite-ref-5[5]), de Dinechin heavily influenced Frederick Raynal, the main developer of Alone in the Dark.cite-ref-6[6] de Dinechin also wrote a few viral games for HP-48 calculators,cite-ref-7[7]cite-ref-8[8] and was the first person to take advantage of hardware-scrolling on these machines.cite-ref-9[9]

In the early 2000s, he worked as a software architect for HP-UX,cite-ref-10[10] and was the initial designer of HP's virtualisation platform for Itanium servers, HP Integrity Virtual Machines. He was awarded 10 US patents for this work.cite-ref-11[11]

Since 2022, he also is the initiator and maintainer of DB48X, a new implementation of RPL.cite-ref-dedinechin-2022-12-0[12]cite-ref-dedinechin-2023-13-0[13]

Christophe de Dinechin did the initial port of Emacs to the Aqua user interface.cite-ref-14[14] He wrote a variety of open-source drivers for the HP DE200C Digital Entertainment Center,cite-ref-15[15] turning it from a web-connected CD Player into a true digital video recorder.

Between 2010 and 2017, Christophe de Dinechin was the CEO of Taodyne, a company developing a 3D animation tool, using a derivative of his XL programming language called Tao3D to describe dynamic documents.cite-ref-16[16]

Dinechin has published three books:

• A French science-fiction novel called Informagiecite-ref-17[17]

• A French book about physics called Réunifions la physiquecite-ref-18[18]

• A physics book called A theory of incomplete measurementscite-ref-19[19]
