QVT to ATL Virtual Machine Compiler

By Frédéric Jouault (INRIA)
June 2007

This work provides a QVT compiler that targets the ATL Virtual Machine (ATL VM), and thus provides executability of QVT programs on top of the ATL VM. The code generator is written in the ACG (Atl Code Generation) Domain-Specific Language (DSL). It takes as input a QVT model (typically in XMI format) that may have been created by a QVT front-end (i.e., a parser and type checker) like Eclipse/modeling/mmt/Procedural QVT, or SmartQVT. The output of the code generator is a “.asm” file similar to the ones generated by the ATL compiler, or the ACG compiler (both also written in ACG).

Overview

This work provides an implementation of one of the QVT-ATL interoperability bridges described in [1]: a QVT to ATL Virtual Machine compiler. This corresponds to the OM to VM arrow on the following figure, taken from [1].

ATL-QVT interoperability through language transformation

ATL-QVT interoperability through language transformation

This use case relies on a QVT front-end (i.e., a parser and type checker) like Eclipse/modeling/mmt/Procedural QVT, or SmartQVT. This front-end generates a QVT model (typically in XMI format) from a QVT program. Then, a code generator written in the ACG (Atl Code Generation) DSL transforms this model into ATL bytecode (i.e., a “.asm” file) that can run on the ATL VM. The current version of this code generator is able to compile the Book2Publication QVT example, and has been tested using the SmartQVT front-end.

ACG is a domain-specific model transformation language. Its domain is ATL VM bytecode generation (i.e., a fixed target metamodel).

None at the current time.
