2007-03-15 H.J. Lu <hongjiu.lu@intel.com> * Makefile.am: Run "make dep-am". * Makefile.in: Regenerated. * config/tc-i386.c: Include "opcodes/i386-opc.h" instead of "opcode/i386.h". (md_begin): Check reg_name != NULL for the last entry in i386_regtab. * config/tc-i386.h: Move many entries to opcode/i386.h and opcodes/i386-opc.h. * configure.in (need_opcodes): Set true for i386. * configure: Regenerated. include/opcode/ 2007-03-15 H.J. Lu <hongjiu.lu@intel.com> * i386.h: Add entries from config/tc-i386.h and move tables to opcodes/i386-opc.h. opcodes/ 2007-03-15 H.J. Lu <hongjiu.lu@intel.com> * Makefile.am (CFILES): Add i386-opc.c. (ALL_MACHINES): Add i386-opc.lo. Run "make dep-am". * Makefile.in: Regenerated. * configure.in: Add i386-opc.lo for bfd_i386_arch. * configure: Regenerated. * i386-dis.c: Include "opcode/i386.h". (MAXLEN): Renamed to MAX_MNEM_SIZE. Remove definition. (FWAIT_OPCODE): Remove definition. (UNIXWARE_COMPAT): Renamed to SYSV386_COMPAT. Remove definition.
