* config/tc-i386.c: REPNE renamed to REPNE_PREFIX_OPCODE, and likewise for REPE. * config/tc-i386.c (reloc): Add braces. * config/tc-i386.c (struct _i386_insn): Rename bi to sib to be consistent with Intel naming. * config/tc-i386.h (base_index_byte): Rename to sib_byte. Don't use bitfields in sib_byte. (modrm_byte): Don't use bitfields here either. * config/tc-i386.c (current_templates): Add const. (parse_register): Add const to return, param, and char *s. (i386_operand): Add const to reg_entry *r. * config/tc-i386.h (templates): Add const to start, end. Inspired by code for 16 bit gas support from Martynas Kunigelis <martynas@nm3.ktu.lt>: * config/tc-i386.c (md_assemble): Add full support for 16 bit modrm, and Jump, JumpByte, JumpDword, JumpInterSegment insns. (uses_mem_addrmode): Remove. (md_estimate_size_before_relax): Add support here too. (md_relax_table): Rewrite interface to md_relax for 16 bit support. (BYTE, WORD, DWORD, UNKNOWN_SIZE): Remove. (opcode_suffix_to_type): Remove. (CODE16, SMALL, SMALL16, BIG, BIG16): Define. (SIZE_FROM_RELAX_STATE): Modify to suit above. (md_convert_frag): Likewise. (i386_operand): Add support for 16 bit base/index regs, immediates, and displacements. Remove some unnecessary casts, and localise end_of_operand_string, displacement_string_start, displacement_string_end variables. Add GCC_ASM_O_HACK. * config/tc-i386.h (NO_BASE_REGISTER_16): Define. * config/tc-i386.c (prefix_hash): Remove. (md_begin): Rewrite without obstacks. Remove prefix hash table handling. Rewrite lexical table handling. (i386_print_statistics): Don't print prefix statistics. (md_assemble): Rewrite instruction parser so that line is not converted to lower case. Don't do a hash_find for prefixes, instead recognise them via opcode modifier. (expecting_operand, paren_not_balanced): Localise variables. * config/tc-i386.h (IsPrefix): Define. (prefix_entry): Remove. * config/tc-i386.h (PREFIX_SEPERATOR): Don't define. * config/tc-i386.c (PREFIX_SEPARATOR): Define here instead, using '\\' in case where comment_chars contains '/'. * config/tc-i386.c (MATCH): Ensure given operand and template match for JumpAbsolute. Makes e.g. `ljmp table(%ebx)' invalid; you must write `ljmp *table(%ebx)'. From H.J. Lu <hjl@gnu.org>: * config/tc-i386.c (BFD_RELOC_16, BFD_RELOC_16_PCREL): Define as 0 ifndef BFD_ASSEMBLER. (md_assemble): Allow immediate operands without suffix or other reg operand to default in size to the current code size.
