A method and system for data centric heap profiling is disclosed. In one embodiment, a method, implemented in a computing device, for data centric heap profiling includes generating a type table for data structure types in source code using a compiler of the computing device. The method also includes identifying each heap allocation site and a corresponding data structure type in the source code using the compiler. The method further includes generating a data centric view of a heap o fan application compiled from the source code based on the each heap allocation site and the corresponding data structure type using a debugger of the computing device when a snapshot of the heap is requested during an execution of the application.

Method and system for data centric heap profiling

A method of debugging an executable computer application comprising instructions of a first computer architecture instruction set and instructions of a second computer architecture instruction set. The method comprises determining whether an instruction being debugged is from the second architecture instruction set; and obtaining debug information from an emulator of the second architecture in a first architecture environment when the instruction being executed is from the second architecture instruction set. The debug information results from emulation of the instruction being debugged.

Method of debugging an executable computer program having instructions for different computer architectures

A technique for building a callgraph for a software program that includes multiple function entry points using dynamic instrumentation. In one example embodiment, this is achieved by inserting function count probe code at each function entry point of each multiple entry function having multiple function entry points in the software program. Inter-entry point arc probe code is then inserted substantially before each arc source address of an arc. A performance analysis tool is then used to collect data resulting from execution of the software program including the function count probe code and the inter-entry point arc probe code and to obtain an actual function count value for each multiple entry function. A callgraph is then built using the obtained actual function count values.
