PR binutils/18025 * coffgen.c (coff_find_nearest_line_with_names): If the dwarf2 lookup fails, check for an address bias in the dwarf info, and if one exists, retry the lookup with the biased value. * dwarf2.c (_bfd_dwarf2_find_symbol_bias): New function. Determines if a bias exists bewteen the addresses of functions based on DWARF information vs symbol table information. * libbfd-in.h (_bfd_dwarf2_find_symbol_bias): Prototype. * libbfd.h: Regenerate.
