How the Debugger Finds Source Files

The debugger searches for a source file (dir_name/base_name) using the following algorithm:


  1. If dir_name is mapped to another source directory (mapped_dir_name), look for mapped_dir_name/base_name.

  2. If Step 1 fails to find a readable file:


    1. Case 1: If dir_name is absolute, look for dir_name/base_name.

    2. Case 2: If dir_name is relative, for each entry use_dir in use_list, look for use_dir/dir_name/base_name. The debugger attempts to use the directories in use_list in the order in which they appear.

  3. If Step 2 fails, for each entry use_dir in use_list, look for use_dir/base_name. The debugger attempts to use the directories in use_list in the order in which they appear.

  4. If Step 3 fails, the debugger cannot find any source file.

The debugger uses the first-found readable file as the source file.
