Abstract
A debugging system according to the present invention includes a decompiler that provides information to a table generator, which generates a line number map and a symbol table, each of which corresponds to an executable file being decompiled. In a specific embodiment, hooks into specific operations performed by the decompiler trigger the table generator operation. A debugging information program can be hooked into a decompiler to generate the debugging information and modify the source code output by the decompiler. For example, the program can be hooked into the decompiler to monitor when the decompiler inserts or deletes source statements, generates line numbers for source lines, or assigns variable names to variables encountered in the executable code.
