Abstract:
An improved technique for inserting reference count code in a garbage collection technique. When there are two or more successor basic blocks to a basic block, a given variable is live at the entry of one or more of the successor basic blocks, and the variable is dead in another basic block S, a new basic block is inserted between the original basic block and a successor basic block in which the variable is dead, and RC− related to the variable is generated in the new basic block.
