Bug ID: 25087
Summary: Stripped symbol handling when using dwo sdebug info
Product: lldb
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: [email protected]
Reporter: [email protected]

Classification: Unclassified
If we use dsym/dwarf as a debug info and a symbol is removed from the object
file during linking (because it is unused) then LLDB correctly reports an error
when the user want to set a breakpoint on it.
In case of dwo debug info the symbol will be still available in the *.dwo file
as it isn't modified by the linker when it removed the unused function. Because
of it LLDB will set a breakpoint at address 0x0 (the address stored at the
location where the symbol address should be stored in the executable) instead
of reporting an error.
