A system includes an abstract machine instruction stream, an execution trace buffer storing information to facilitate dynamic compilation, a virtual machine coprocessor configured to receive an instruction from the abstract machine instruction stream and to generate one or more native machine instructions in response to the received instruction, and a processor coupled to the virtual machine coprocessor and operable to execute the native machine instructions generated by the virtual machine coprocessor. The virtual machine coprocessor updates the execution trace buffer as instructions from the abstract machine instruction stream are processed. In addition, a method for facilitating dynamic compilation includes receiving an instruction to be processed, determining that the instruction marks entry into a basic block, and updating an execution trace buffer.
