RESUMO

Reduced Instruction Set Computers (RISCs) offer higher performance through their very simple instruction repertoire and its efficient hardware implementation. On the other hand, studies of object code generated by compilers for high level languages have shown that the most frequently executed instructions are exactly the simplest ones. The improvement in performance of a general purpose computer is thus result of an integrated approach to compiler construction and architecture. These ideas have influenced design concepts in both areas. In this dissertation we try to characterize these new architectures and their relation to compiling techniques, especially code optimization. Several aspects related to RISCs, such as, register allocation and pipelines optimization are discussed. Some of the ideas discussed or proposed were tried within a production compiling system on SPARC (Sun Microsystems) architecture
