commit 1f8592d1a615bef5bad1f255e761664e85d9e4f0
Author: Mark Wielaard <mjw@redhat.com>

    PR10305 Mark probes fail on prelinked shared library.
    
    Mark probes rely on literal statement addresses, these are based on the
    on-disk module address space. Introduce helper function to turn such
    addresses into symbol addresses as expected by libdwfl. Also properly
    adjust for dw bias when such addresses are used in dw queries.
    
    * dwflpp.h (dwflpp::literal_addr_to_sym_addr): New method.
    * dwflpp.cxx (query_cu_containing_address): Don't "globalize" address.
      (literal_addr_to_sym_addr): New method.
    * tapsets.cxx (query_module_dwarf): Turn literal addresses into symbol
      addresses.
      (query_dwarf_func): Likewise and adjust for dw module bias.
