* config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
also before setting STYP_NOLOAD for .bss section.
* config/tc-m68k.c (flag_reg_prefix_optional): New variable.
Initialized to value of REGISTER_PREFIX_OPTIONAL, if defined, or
zero.
(m68k_reg_parse): If flag_reg_prefix_optional is set, permit
register prefix to be absent.
(m68k_ip_op): Accept `&' also for immediate constants.
(insert_reg): Don't bother with (two!?) sanity checks of the
symbol table when inserting each register.
(m68k_parse_long_option): New function. Set
flag_reg_prefix_optional if "register-prefix-optional" is passed.
* config/tc-m68k.h (REGISTER_PREFIX): Always define if not already
defined.
(OPTIONAL_REGISTER_PREFIX): Don't define.
(REGISTER_PREFIX_OPTIONAL): If not already defined, define as zero
or one depending on M68KCOFF.
Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
* config/tc-m68k.c (DATA, ADDR, SP, FPREG, COPNUM, BAD, BAC):
Define as macros instead of enumerators, since the Apollo compiler
can't handle "enumVal1, enumVal2 = enumVal1" when defining an enum
type.
(make_pcrel_absolute) [NO_PCREL_RELOCS]: New function.
(tc_coff_fix2rtype) [NO_PCREL_RELOCS]: Generate only R_RELBYTE,
R_DIR16, and R_DIR32 relocs.
* config/tc-m68k.h [TE_APOLLO] (COFF_MAGIC, COFF_AOUTHDR_MAGIC):
Use Apollo versions.
[TE_APOLLO] (OBJ_COFF_OMIT_OPTIONAL_HEADER): Undefine. That is,
do include the optional header for Apollo target.
(COFF_MAGIC): Don't define as MC68MAGIC if it's already defined.
* config/tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%'
can be used within a label name.
* config/tc-m68k.h (m68k_init_after_args): Declare.
(tc_init_after_args): Define as m68k_init_after_args.
* config/tc-m68k.c (m68k_init_after_args): New function,
containing one-shot code from md_assemble. Added warning for
combination of 68040 and 68851.
(md_assemble): Startup-time code deleted.

* doc/Makefile.in (clean, distclean): Remove asconfig.texi.
