Hi,
After setting a breakpoint, GDB can read the location information from the symbol table constructed by dwarf and fill in the breakpoint;
Why need a linked list to record multiple location information;
Where do so many locations come from?
Thank you very much.

Inlining can cause multiple locations. So can overloading, wild
matching, or something like a template instantiation when a "file:line"
breakpoint is used.
