Affix grammar driven code generation

Abstract

Affix grammars are used to describe the instruction set of a target architecture for purposes of compiler code generation. A code generator is obtained automatically for a compiler using attributed parsing techniques. A compiler built on this model can automatically perform most popular machine-dependent optimizations, including peephole optimizations. Code generators based on this model demonstrate retargetability for the VAX 1 -11, iAPX 2 -86, Z-8000 3 , PDP 4 -11, MC-68000, NS32032, FOM, and IBM-370 architectures.
