ABSTRACT:
A mechanism is provided in a debugger for building a file information database while significantly reducing debug startup time. For each line number table, the mechanism of the present invention reads the header section and determines all the source files that contribute to the line number table. The mechanism also makes note of the line number table offset. The mechanism then inserts the source filename into the file information database. In one preferred embodiment, the file information database is implemented as a hash table. Searching time occurs during an interactive debug session; therefore, the searching time is not easily detectable to a user, thus creating the perception of a faster interactive debugging session.
