Jim Kingdon 2d336b1b51 * 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.
