>From the gcc internals manual:

 * Debugging information output

     This is run after final because it must output the stack slot
     offsets for pseudo registers that did not get hard registers.
     Source files are `dbxout.c' for DBX symbol table format,
     `sdbout.c' for SDB symbol table format, `dwarfout.c' for DWARF
     symbol table format, files `dwarf2out.c' and `dwarf2asm.c' for
     DWARF2 symbol table format, and `vmsdbgout.c' for VMS debug symbol
     table format.
