Looking at the Source Files. Expert Debugging

The debugger supports commands to perform the following operations with source files:

• Determine the location of the source files
• Select a particular file as the current file
• List portions of the current file
• Search through the current file for target strings

browse_source_command

        : source_directory_mapping_command

        | source_searchlist_command

        | select_source_file_command

        | list_source_file_command

        | search_source_file_command

Special debugging information that the compiler puts in the .o files correlates the machine instructions and data back to the source files and the positions they came from.

Source files are compiled and linked into executable files. During debugging, the debugger tries to find these source files to display them for you. If the source files have moved, or if the paths to them are relative, the debugger may not be able to locate them. All the information the debugger needs comes from the executable files or shared libraries, not from the source files.
