Abstract: A method of analyzing source code includes receiving, by a processor, an updated version of a computer program, the updated version including a source code. The method also includes preprocessing, by a compiler, the source code for a target computing platform. Preprocessing the source code by the compiler includes identifying a macro condition associated with one or more computer instructions enclosed by a macro, determining object code corresponding to the one or more computer instructions based on a current value of the macro condition, and generating object code and macro information for output to a debugger, the macro information including one or more breakpoint conditions in the macro.

Abstract: A computer-implemented method includes receiving, by a processor, an updated version of a computer program that includes several source code changes. A compiler preprocesses the source code changes for a target computing platform. The preprocessing includes identifying a compile time condition associated with one or more computer instructions enclosed by a macro, determining a current value of the compile time condition at the time of compiling, and determining corresponding object code based on the current value. Further, a macro information record for the macro is generated that includes the compile time condition, the current value, and an identification of the computer instructions. Further, a linker preprocesses the source code changes. This preprocessing includes determining that the object code is not included in an executable file, and updating the macro information record to indicate that the macro is not included in the executable file.

Abstract: A computer-implemented method includes preprocessing, by a compiler, a plurality of macros in a computer program. Preprocessing a macro includes identifying a compile time condition associated with the macro. Preprocessing the macro further includes determining a current value of the compile time condition at the time of compiling a computer instruction and a previous value of the compile time condition. Preprocessing the macro further includes determining a set of computer instructions enclosed by the macro. The method further includes storing a macro information record that includes the compile time condition, the current value and the previous value of the compile time condition, and an identification of the set of computer instructions enclosed by the macro.

Abstract: A computer receives a log file, where the log file comprises records associated with the instructions in a source code. The computer loads, using a debugger, the log file and the source code. The computer receives a loading address from the log file. The computer updates a debugging data format (DWARF) with the one or more records of the log file, where the DWARF is accessed using the loading address and comprises one or more data structure entries. The computer identifies a calling address from the log file and identifies the one or more data structure entries associated with the calling address.
