Today's high-performance microprocessors rely heavily on compilers to
actually deliver their impressive raw computing power to applications.
Sophisticated hardware demands a matching, sophisticated compiler.
Every new target architecture requires a new code generator.
Implementations of the same target architecture often vary
significantly in capability, ranging from microprocessors targeting
embedded applications to supercomputing. Consequently, code
generators need to be customized to specific processors to fully
exploit their capabilities. Likewise, they need to be extended to
take advantage of new versions of the architecture.
Requirements for compilers also vary widely. A more traditional,
optimizing compiler that runs in a batch process needs a different
code generator than a just-in-time compiler for a rapid application
development environment.
Developing such code generators by hand is difficult, error prone and
expensive. The results are often hard to maintain, hard to customize,
and hard to extend.
BEG compiler code generation tool
was designed to address these problems.
