[rvm-research] annotation to avoid write barrier on selected methods?

Hi All,
 
Hi again from Canberra! I am wondering if there is an annotation in Jikes to tell the compiler not to spit write barriers for the annotated methods? Basically in GenImmix, on a reference update, I want to call a (special) method that allocates and moves objects from one location (nursery) to another (mature-immix). Accomplishing this using Magic code alone is more than clumsy. I would like to call if possible built-in methods in ObjecModel.java for allocating/copying objects. Any advice is appreciated!

Cheers,
Shoaib
