This +debugging information describes features of the source file like line +numbers, the types and scopes of variables, and function names, +parameters, and scopes. +</p> +<p>For some object file formats, the debugging information is encapsulated +in assembler directives known collectively as <em>stab</em> (symbol table) +directives, which are interspersed with the generated code. Stabs are +the native format for debugging information in the a.out and XCOFF +object file formats. The GNU tools can also emit stabs in the COFF and +ECOFF object file formats. +</p> +<p>The assembler adds the information from stabs to the symbol information +it places by default in the symbol table and the string table of the +<samp>.o</samp> file it is building. The linker consolidates the <samp>.o</samp> +files into one executable file, with one symbol table and one string +table. Debuggers use the symbol and string tables in the executable as +a source of debugging information about the program. +</p> + + + +</body> +</html> |
