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. * 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: * 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. * 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. * tc-m68k.h [TE_DELTA] (LEX_PCT): Define as 1, so that `%' can be used within a label name. * tc-m68k.h (m68k_init_after_args): Declare. (tc_init_after_args): Define as m68k_init_after_args. * 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.
