This paper describes a just-in-time (JIT) Java1 compiler for the Intel¯ Itanium¯ processor. The Itanium processor is an example of an Explicitly Parallel Instruction Computing (EPIC) architecture and thus relies on aggressive and expensive compiler optimizations for performance. Static compilers for Itanium use aggressive global scheduling algorithms to extract instruction-level parallelism. In a JIT compiler, however, the additional overhead of such expensive optimizations may offset any gains… CONTINUE READING
