x86 architecture 2 byte opcodes note: A leading bold V indicates that the instruction can be VEX-encoded, in which case it may have additional operands. note: A leading bold ! indicates that the 256-bit version was only introduced with AVX2 and that it can only be VEX-encoded. note: AVX10.1 is comprised of AVX512{F,CD,BW,DQ,VL,IFMA,VBMI,VNNI,BF16,VBMI2,BITALG,VPOPCNTDQ,FP16} and of the EVEX-encoded variants of VAES, GFNI, and VPCLMUL, but not AVX512{PF,ER,QFMA,QVNNIW,VP2INTERSECT}. AVX512QVNNI didn't ship in KNM as originally planned. AVX512DFMA and AVX512BITALG2 were specified but didn't ship. note: AVX10.2 is comprised of {BF16,COMX,CVTFP8,DP,SAD,MINMAX,CVTS,VMOV} and 256-bit {er} and {sae} variants. note: A leading bold !! indicates that the 256-bit {er} or {sae} variant, encoded with U=0, was only introduced with AVX10.2. note: Although SM4-EVEX, VMOVRS* from MOVRS, and AMX-AVX512 depend on AVX10.2, they are not part of AVX10.2. pre- fix 0Fh xxh   x0h   x1h x2h x3h x4h x5h x6h x7h   n/a   0xh group #6 group #7 LAR Gv,Ew LSL Gv,Ew SAVEALL (80286) see here for more LOADALL (80286) SYSCALL (see CPUID) CLTS LOADALL

They are encoded as the Ib, using 00...07h. With VEX, there also are: EQ_UQ, NGE, NGT, FALSE, NEQ_OQ, GE, GT, TRUE (08...0Fh), EQ_OS, LT_OQ, LE_OQ, UNORD_S, NEQ_US, NLT_UQ, NLE_UQ, ORD_S (10h...17h), and EQ_US, NGE_UQ, NGT_UQ, FALSE_OS, NEQ_OS, GE_OQ, GT_OQ, TRUE_US (18...1Fh). However, with MVEX only EQ, LT, LE, UNORD, NEQ, NLT, NLE, and ORD are valid (00...07h). #3 Ideally the Vo,Ho,Wo variants would be Vo,Ho,Wo.q because they only use the lower half of the source operand. #4 Ideally the Vo,Ho,Wo variants would be Vo,Ho,Wo.b because they only use the lowest byte of the source operand.
