Abstract
A method and an apparatus for concurrent accessing of dynamically type objects based on inline cache code are described. Inline cache initialization in a single thread may be off loaded to an interpreter without incurring unnecessary synchronization overhead. A thread bias mechanism may be provided to detect whether a code block is executed in a single thread. Further, the number of inline cache initializations performed via a compiler, such as baseline JIT compiler, can be reduced to improve processing performance.
