Abstract: Method and apparatus for enhancing an executable is disclosed herein. In one embodiment, the method includes instrumenting an executable with additional program code to detect run-time errors, and while running the instrumented executable within a debug environment generating the run-time errors detected by the additional program code, upon reaching a breakpoint, identifying any of the run-time errors which occurred while executing a function in which the breakpoint is located, and transmitting an indication of the identified run-time errors to the debugging environment.

Abstract: Embodiments disclosed herein generally include a computer-implemented method, computer program product, and system to facilitate offloaded and parallelized direct memory access (DMA) translation table operations. The method includes a hypervisor requesting a lease on an auxiliary parallel processing element assigned to a first virtual machine hosted by the hypervisor. The method further includes receiving a grant of the lease, whereby ownership of the auxiliary parallel processing element is transferred from the first virtual machine to the hypervisor. The method further includes, during the lease, providing a predefined program to execute on the auxiliary parallel processing element in order to perform a desired operation on the hypervisor DMA translation table and with parallelism. The method further includes, upon completion of the predefined program, terminating the lease by the hypervisor, whereby ownership of the auxiliary parallel processing element is returned to the first virtual machine.

Abstract: Disclosed aspects include identifying basic blocks of a program. For each basic block, the compiler inserts an identifier that includes the function name, and is coupled with a counter variable. In response to generating the identifier coupled with the counter variable, the program is compiled. During program execution, the counter value is incremented in response to a call of the basic block when executing the program. In response to incrementing the counter value, the counter value coupled with the identifier is displayed.

Abstract: A pre-initialized value of contents of a memory location is identified. A load value of contents loaded from the memory location by execution of a first instruction that loads from the memory location is also identified. A comparison is made between the load value and the pre-initialized value. Based on the comparison, a determination is made that the load value and the pre-initialized value are the same. In response to this determination, it is indicated that the first instruction contains an uninitialized memory reference.

Abstract: A computer implemented method for identifying program flow in a computer program, executing in a debugger on at least one processor, subsequent to suspending execution of the computer program at a user breakpoint can include suspending execution of the computer program at a first user breakpoint, setting, by the debugger, one or more tracking breakpoints in one or more routines that can continue execution from the first user breakpoint, then resuming execution of the computer program. The method may be continued by suspending execution of the computer program at a second user breakpoint after processing by the at least one processor at least one instruction of the computer program. The method may further include determining whether to provide an indicator to indicate that at least one of the one or more tracking breakpoints was hit during the executing, and providing the indicator in response to determining to provide the indicator.

Abstract: Disclosed aspects include a debugger evaluating an expression. The expression has a debug element. Using dynamic analysis, a set of state information related to the debug element is identified. The set of state information can be generated external to the debugger and used within the debugger subsequent to being generated. Utilizing the set of state information, a tolerance parameter is selected. The tolerance parameter is for a conditional breakpoint linked with the debug element. In response to selecting the tolerance parameter, a triggering event for the conditional breakpoint may be detected. Based on the tolerance parameter, it may be determined to disregard the triggering event. Subsequently, the triggering event can be disregarded. Altogether, aspects of the disclosure provide a methodology for debug management that may provide performance or efficiency benefits.

Abstract: Techniques are disclosed for classifying system library errors detected by a dynamic analysis tool executing in a first client of a plurality of clients. The dynamic analysis tool monitors an execution of an application. The dynamic analysis tool identifies one or more errors that are related to at least one of a plurality of system libraries called by the application during the execution. For each identified error, the dynamic analysis tool evaluates the error relative to error data observed in a dynamic analysis tool executing in the other clients, and flagging the error as an error that is not caused by a user based on the evaluation.
