<pre>Currently, llvm-symbolizer tries to look up input addresses using the object's
debug data only. If it fails to find the address using the information (most
likely because there is no data), it prints the not found pattern.
GNU's addr2line still prints a symbol name, if --functions is enabled:
C:\Work> addr2line --functions 0x1f5 -e test.elf
a_symbol
??:0
Whilst I haven't looked at how it does this, it seems reasonable to assume that
it is looking up the information from the symbol table. I don't see any reason
why we can't look that information up either.</pre>
