This requires parsing symbol +files corresponding to the libraries of the emulated system, in order to extract +relevant information from them. + +Due to lack of windows support on available open source projects, this is a +full new implementation of an ELF/DWARF parser. + +The library exposes a simple API that at this point allows: +- Extract information about routine, containing given PC address in the emulated + system. Routine information, collected by the library includes: + * Routine name + * Source file name and line corresponded to the given emulated PC. + * If routine happens to be inlined, library traces inclusion up to the first + routine that is not inlined, providing names and source file location + information for all inlined routines in that chain. |
