Vocabularycompiler.cfg.instructionsClass descriptionAn instruction for inserting a write barrier. This instruction is almost always inserted after a
##set-slot instruction. If the container object is in an older generation than the item inserted, this instruction guarantees that the item will not be garbage collected. It has the following slots:
src | Object to which the writer barrier refers. |
slot | Slot index of the object. |
scale | No idea. |
tag | Type tag for obj. |
temp1 | First temporary register to clobber. |
temp2 | Second temporary register to clobber. |
