RESUMO
Due to the increasing complexity of the new processors, mainly DSPs processors, the capacity of generating highly optimized code for the new computer architectures by the compilers is increasingly motivating. The Xingó compiler has as goal allow research in code optimization and code generation for new architectures. In order to enable such researches, is necessary to the compiler to provide an infrastructure capable of representing, in an easy and correct form, the code in the several compiling phases. This work presents the main program representations of the Xingó compiler, and the modules that perform the conversion of a program, in a base representation, to a program in a destination representation (intermediate or ultimate). These modules constitute the front-end of the compiler, that generates the Xingó Intermediate Representation, and share of the back-end, with highlight to the Xingó Code Generation Infrastructure. The Xingó Intermediate Representation is easy to use, it is machine independent and has a very approximate syntax of the C language, thereby it has enabled to perform machine independent optimizations and is able to be converted to C Code. Upon the Code Generation Infrastructure, it provides facilities to development of new code generators, mainly because the details of the target machine are outside to the compiler, been included across configurable parameters and well-defined modules.The tests completed up to now validate piece of the Code Generation Infrastructure and reveal good quality of the Xingó Intermediate Code. The testes show that the Intermediate Code is been correctly generated to any programs of the NullStone benchmark (6611 programs) and also to a reasonable quantity of programs of the MediaBench and SPEC benchmarks. The test results acquired up to now conduce to new opportunities for researches on areas such as optimization and code generation
