Zero-Assembler Project

Zero is a port of OpenJDK that uses no assembler and therefore can trivially be built on any system. The goal of this project is be to be able to build a TCK-compliant OpenJDK of reasonable performance on any platform with no additional porting work.

The interpreter part of Zero is known to work on PowerPC (32- and 64-bit), x86-64, IA-64, ARM and zSeries. Zero is currently Linux- and GCC-specific, but supporting other operating systems and compilers is one area in which contributions are particularly welcome.

Work is currently under way on an LLVM-based JIT known as Shark.

This Project is sponsored by the Porters Group.
