Title:
METHOD FOR FAST COMPILATION OF PREVERIFIED JAVA BYTECODE TO HIGH QUALITY NATIVE MACHINE CODE
Document Type and Number:
WIPO Patent Application WO2002097552
Kind Code:
A3
Abstract:
The present invention is a new method and apparatus to perform fast compilation of platform independent bytecode instruction listings into high quality machine code in a single sequential pass. More specifically, the present invention creates a new method and apparatus for the translation of platform neutral bytecode into high quality machine code in a single sequential pass in which information from the preceding instruction translation is used to mimic an optimizing compiler without the extensive memory and time requirements. Where the preceding instruction translation cannot be used due to no direct control flow, information from comprehensive stack maps is then used.
