* config/sparc/tm-sun4sol2.h, dbxread.c: Rename
N_SO_ADDRESS_MAYBE_MISSING to SOFUN_ADDRESS_MAYBE_MISSING. * symtab.h (minimal_symbol) [SOFUN_ADDRESS_MAYBE_MISSING]: Add filename field. * elfread.c (record_minimal_symbol_and_info), minsyms.c, symtab.h (prim_record_minimal_symbol_and_info): Return newly created symbol. * elfread.c (elf_symtab_read) [SOFUN_ADDRESS_MAYBE_MISSING]: Set filename field of minimal symbol. * symmisc.c (dump_msymbols) [SOFUN_ADDRESS_MAYBE_MISSING]: Print filename field. * minsyms.c, symtab.h (lookup_minimal_symbol): New arg sfile. * symm-tdep.c, somsolib.c, hppa-tdep.c, c-exp.y, f-exp.y, m2-exp.y, nindy-tdep.c, m3-nat.c, irix5-nat.c, hpread.c, os9kread.c, breakpoint.c, alpha-tdep.c, valops.c, symtab.c, printcmd.c, dbxread.c: Change callers to pass NULL for sfile. * dbxread.c (process_one_symbol) [SOFUN_ADDRESS_MAYBE_MISSING]: Find address of function from minimal symbols. * partial-stab.h, case 'f', 'F': Call find_stab_function_addr instead of getting pst->textlow from the stab. * minsyms.c (find_stab_function_addr): New function.
