Abstract
Using hardware transactional memory (HTM) for queue operations includes invoking a first operation for a concurrent linked queue of an interpretive program using a Just-In-Time (JIT) compiler of a virtual machine, wherein the first operation does not use HTM, determining whether a data processing system executing the virtual machine supports HTM, and responsive to determining that the data processing system does support HTM, detecting, using a processor and within the first operation, a call to a second operation that is that is configured, in byte code, to return an indication of a failed hardware transaction. Responsive to detecting the second operation, a machine code implementation of the first operation that includes a machine code implementation of the second operation is generated. The machine code implementation of the second operation is an implementation of the first operation that does use HTM.
