Experiences porting the jikes RVM to Linux/IA32

This paper describes our experiences in porting the Jikes Research Virtual Machine from its first platform, AIX/PowerPC, to its second, Linux/IA32. We discuss the main issues in realizing both an initial functional port and then tuning efforts to achieve competitive performance. The paper presents software engineering issues in building a portable runtime system and compilers, as well as specific opti mizations to improve performance on IA32.
