With increasing complexity of modern embedded systems, the availability of highly optimizing compilers becomes more and more important. At the same time, application specific instruction-set processors (ASIPs) are used to fine-tune hardware platforms to the intended application, demanding the availability of retargetable components throughout thewhole tool chain.

A very promising approach is to model the target architecture using a dedicated description language that is rich enough to generate hardware components and the required tool chain, e.g., assembler, linker, simulator, and compiler.

In this work we present a new structural architecture description language (ADL) that is used to derive the architecture dependent components of a compiler backend - most notably an instruction selector based on tree pattern matching. We combine our backend with gcc, thereby opening up the way for a large number of readily available high level optimizations. Experimental results show that the automatically derived code generator is competitive in comparison to a handcrafted compiler backend.
