Abstract: A method finds an error in a computer program. A plurality of execution breakpoints are set in the computer program. A portion of the execution of the computer program is simulated as recorded in the trace data in the reverse order until one a plurality of conditions is met, wherein one of the plurality of conditions is an attempt to execute a machine instruction associated with one of the plurality of execution breakpoints.

Abstract: A method finds an error in a computer program. A sequence of machine instructions performed by a processor is recorded as trace data. Further, at least one event is selected from a plurality of events. In addition, an operating system instruction address is determined for the at least one event. Further, at least a portion of the trace data is searched for the operating system instruction address. The execution time for an operating system instruction stored in the operating system instruction address is determined. The execution time is searched through in the database to find task related data. The task related data is displayed.

Abstract: A method for finding an error in a computer program is disclosed. A sequence of machine instructions performed by a processor is recorded as trace data. A mapping file is accessed. A source code instruction is translated into a machine code instruction according to a mapping found in the mapping file. Further, at least a portion of the trace data is searched through until the machine code instruction is found. In addition, a first execution time of the machine code instruction is determined by reviewing the trace data in a first vicinity that an address of the machine code instruction is located. Further, a second execution time of the next machine code instruction is determined by reviewing the trace data in a second vicinity that an address of the next machine code instruction is located. Accordingly, performance data is calculated by subtracting the first execution time from the second execution time. The performance data is displayed.

Abstract: A method and system debug a computer program by using trace data, which is a recording of the sequence of machine instructions executed by a program during a time period along with the addresses and values of memory locations accessed and modified by each machine instruction. After the time period, the method and system use the trace data to simulate the execution of the program during the time period under the control of a debugger. In addition, the method and system use the trace data to simulate the execution of the program during the time period backwards in time under the control of the debugger.
