+
+ * i386-dis.c (dis386_intel): Remove macro chars, except for
+ jEcxz. Change cWtR and cRtd to cW and cR.
+ (dis386_twobyte_intel): Remove macro chars here too.
+ (putop): Handle R and W macros for intel mode.
+
+ * i386-dis.c (SIMD_Fixup): New function.
+ (dis386_twobyte_att): Use it on movlps and movhps, and change
+ Ev to EX on these insns. Change movmskps Ev, XM to Gv, EX.
+ (dis386_twobyte_intel): Same here.
+
+ * i386-dis.c (Av): Remove.
+ (Ap): remove lptr.
+ (lptr): Remove.
+ (OPSIMD): Define.
+ (OP_SIMD_Suffix): New function.
+ (OP_DIR): Remove dead code.
+ (eAX_reg..eDI_reg): Renumber.
+ (onebyte_has_modrm): Table numbering comments.
+ (INTERNAL_DISASSEMBLER_ERROR): Move to before print_insn_x86.
+ (print_insn_x86): Move all prefix oappends to after uses_f3_prefix
+ checks. Print error on invalid dp->bytemode2. Remove simd_cmp,
+ and handle SIMD cmp insns in OP_SIMD_Suffix.
+ (info->bytes_per_line): Bump from 5 to 6.
+ (OP_None): Remove.
+ (OP_E): Use INTERNAL_DISASSEMBLER_ERROR. Handle sfence.
+ (OP_3DNowSuffix): Ensure mnemonic index unsigned.
+
+ PIII SIMD support from Doug Ledford <dledford@redhat.com>
+ * i386-dis.c (XM, EX, None): Define.
+ (OP_XMM, OP_EX, OP_None): New functions.
+ (USE_GROUPS, USE_PREFIX_USER_TABLE): Define.
+ (GRP14): Rename to GRPAMD.
+ (GRP*): Add USE_GROUPS flag.
+ (PREGRP*): Define.
+ (dis386_twobyte_att, dis386_twobyte_intel): Add SIMD insns.
+ (twobyte_has_modrm): Add SIMD entries.
+ (twobyte_uses_f3_prefix, simd_cmp_op, prefix_user_table): New.
+ (grps): Add SIMD insns.
+ (print_insn_x86): New vars uses_f3_prefix and simd_cmp. Don't
+ oappend repz if uses_f3_prefix. Add code to handle new groups for
+ SIMD insns.
+
+ From Maciej W. Rozycki <macro@ds2.pg.gda.pl>
+ * i386-dis.c (dis386_att, dis386_intel): Change 0xE8 call insn
+ operand from Av to Jv.
