In computing, compiler correctness is the branch of computer science that deals with trying to show that a compiler behaves according to its language specification. [ citation needed ] Techniques include developing the compiler using formal methods and using rigorous testing (often called compiler validation) on an existing compiler.
Simplified excerpt of the formal grammar [1] for the C programming language (left), and a derivation of a piece of C code (right) from the nonterminal symbol . Nonterminal symbols are blue and terminal symbols are red.
A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.
Formal verification is the use of software tools to prove properties of a formal specification, or to prove that a formal model of a system implementation satisfies its specification. Once a formal specification has been developed, the specification may be used as the basis for proving properties of the specification, and by inference ...
This is usually undesirable, but has been used in interesting ways—see the Chicken Scheme compiler. As CPS and TCO eliminate the concept of an implicit function return, their combined use can eliminate the need for a run-time stack. Several compilers and interpreters for functional programming languages use this ability in novel ways. [6]
A convention in one language may be a requirement in another. Language conventions also affect individual source files. Each compiler (or interpreter) used to process source code is unique. The rules a compiler applies to the source creates implicit standards.
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 translate source code from a high-level programming language to a low-level programming language (e.g ...
JoCaml is the first language where the join-pattern was implemented. Indeed, at the beginning all the different implementation was compiled with the JoCaml Compiler. JoCaml language is an extension of the OCaml language. It extends OCaml with support for concurrency and synchronization, the distributed execution of programs, and the dynamic ...
