Incremental generation of high-quality target code by MARY P. BIVENS and MARY LOU SOFFA

چکیده
Although conventional compilers frequently apply optimization techniques in the generation of target code, some current incremental compilers do not support commonly used optimizations. This work extends the concept of incremental compilation to fine-grained, high-quality target code generation. The proposed incremental code generator changes only the affected target code and register allocations in response to a source program edit. In this paper, we first discuss some issues and analyze the actions and information needed for developing incremental code generators. From the analysis, incremental techniques for allocating registers and generating target code are developed. Both local and global register allocation are considered, using graph coloring as the allocation scheme. To evaluate the performance of the incremental system, both incremental and non-incremental systems are implemented on a VAX, and their performance is compared in terms of the quality of the target code and the savings (40% to 80% ) in time for making changes incrementally rather than completely regenerating the target code.

Although code optimizations are necessary to parallelize code, few guidelines exist for determining when and where to apply optimizations to produce the most efficient code. The order of applying optimizations can also have an impact on the efficiency of the final target code.
