, tombstone diagrams (or T-diagrams) consist of a set of “puzzle pieces” representing compilers
In computing, a compiler is a computer program that translates computer code written in one programming language (the ''source'' language) into another language (the ''target'' language). The name "compiler" is primarily used for programs that ...
and other related language processing programs. They are used to illustrate and reason about transformations from a source language (left of T) to a target language (right of T) realised in an implementation language (bottom of T). They are most commonly found describing complicated processes for bootstrapping
In general, bootstrapping usually refers to a self-starting process that is supposed to continue or grow without external input.

UNCOL UNCOL (Universal Computer Oriented Language) is a universal intermediate language for compilers. The idea was introduced in 1958, by a SHARE ad-hoc committee. It was never fully specified or implemented; in many ways it was more a concept than a l ...

*Bootstrapping (compilers)
In computer science, bootstrapping is the technique for producing a self-compiling compiler – that is, a compiler (or assembler) written in the source programming language that it intends to compile. An initial core version of the compiler (the ...
