Re: [Jikesrvm-researchers] Building BaseBaseConcurrent

[David F. B. <df...@wa...>]

yes, the concurrent collector only works on PowerPC with the Base compiler.  porting it to
intel would involve porting the assembler code for the write barriers, which has a different
structure than other write barriers because of the need to store both the old and the new
address, and to use an atomic instruction to update the pointer.

let me know if you need more information.
