+ * i386-dis.c (XMGatherD, VexGatherD): New.
+ (vex_table): Use VexGatherD for vpgatherd* and vgatherdp*.
+ (print_insn): Check masking for S/G insns.
+ (OP_E_memory): New local variable check_gather. Extend mandatory
+ SIB check. Check register conflicts for (EVEX-encoded) gathers.
+ Extend check for disallowed 16-bit addressing.
+ (OP_VEX): New local variables modrm_reg and sib_index. Convert
+ if()s to switch(). Check register conflicts for (VEX-encoded)
+ gathers. Drop no longer reachable cases.
+ * i386-dis-evex.h (evex_table): Use XMGatherD for vpgatherd* and
+ vgatherdp*.

* i386-dis.c (print_insn): Mark as bad EVEX encodings specifying
zeroing-masking without masking.
