Abstract
A computer implemented method for dynamically setting hint fields of instructions. Machine executable code is modified during execution to locate and replace instructions having hint fields. The instructions are replaced with calls to intercept the execution flow and redirect to procedures of a monitor. During execution of the machine executable code, hint information is recorded in a memory. The recorded hint state information is analyzed to determine the most frequently occurring or best hint value. When a best hint value has been determined, the replaced instructions are restored with best hint values.
