No, it says, for every source line, which PC addresses correspond to
that source line. That is all GDB needs to know, because it
manipulates PC addresses (i.e. addresses in the .text section).
For symbols, the debug info says that symbol `foo' is stored in the
.text or .data section (or .bss or something else) at address NNN.

Not necessarily, see my other message.
