Hi, guys:
Linux kernel has announced a new ELF ABI: x32 which using 32bit addressing mode but with 64bit data registers. This mode is intended to cut down pointer size by 4bytes to reduce memory usage while using full facilities provided by x86-64. I am porting OpenJDK 7 to this mode, but find the assembler_x86_cpp is bound to generated 64bit addressing mode ,and a lot of another x86 relcated file has similar matters, any body can help? And suggestion is approciated!
