...55// to the Go and GNU assembler opcode suffix.56//57// The complete line used for the above examples is:58//59//	"SHR r/m32, imm8","SHRL imm8, r/m32","shrl imm8, r/m32","C1 /5 ib","V","V","","operand32","rw,r","Y","32"60//61// Mnemonics62//63// The instruction mnemonics are as used in the Intel manual, with a few exceptions.64//65// Mnemonics claiming general memory forms but that really require fixed addressing modes66// are omitted in favor of their equivalents with implicit arguments..67// For example, "CMPS m16, m16" (really CMPS [SI], [DI]) is omitted in favor of "CMPSW".68//69// Instruction forms with an explicit REP, REPE, or REPNE prefix are also omitted.70// Encoders and decoders are expected to handle those prefixes separately.71//72// Perhaps most significantly, the argument syntaxes used in the mnemonic indicate73// exactly how to derive the argument from the instruction encoding, or vice versa.74//75// Immediate values: imm8, imm8u, imm16, imm16u, imm32, imm64.76// Immediates are signed by default; the u suffixes indicates an unsigned value.77//78// Memory operands. The forms m, m128, m14/28byte, m16, m16&16, m16&32, m16&64, m16:16, m16:32,79// m16:64, m16int, m256, m2byte, m32, m32&32, m32fp, m32int, m512byte, m64, m64fp, m64int,80// m8, m80bcd, m80dec, m80fp, m94/108byte. These operands always correspond to the81// memory address specified by the r/m half of the modrm encoding.82//83// Integer registers.84// The forms r8, r16, r32, r64 indicate a register selected by the modrm reg encoding.85// The forms rmr16, rmr32, rmr64 indicate a register (never memory) selected by the modrm r/m encoding.86// The forms r/m8, r/m16, r/m32, and r/m64 indicate a register or memory selected by the modrm r/m encoding.87// Forms with two sizes, like r32/m16 also indicate a register or memory selected by the modrm r/m encodng,88// but the size for a register argument differs from the size of a memory argument.89// The forms r8V, r16V, r32V, r64V indicate a register selected by the VEX.vvvv bits.90//91// Multimedia registers.92// The forms mm1, xmm1, and ymm1 indicate a multimedia register selected by the93// modrm reg encoding.94// The forms mm2, xmm2, and ymm2 indicate a register (never memory) selected by95// the modrm r/m encoding.96// The forms mm2/m64, xmm2/m128, and so on indicate a register or memory97// selected by the modrm r/m encoding.98// The forms xmmV and ymmV indicate a register selected by the VEX.vvvv bits.99// The forms xmmI and ymmI indicate a register selected by the top four bits of an /is4 immediate byte.100//101// Bound registers.102// The form bnd1 indicate a  bound register selected by the modrm reg encoding.103// The form bnd2 indicates a bound register (never memory) selected by the modrm r/m encoding.104// The forms bnd2/m64 and bnd2/m128 indicate a register or memorys selected by the modrm r/m encoding.105// TODO: Describe mib.106//107// One-of-a-kind operands: rel8, rel16, rel32, ptr16:16, ptr16:32,108// moffs8, moffs16, moffs32, moffs64, vm32x, vm32y, vm64x, and vm64y109// are all as in the Intel manual.110//111// Encodings112//113// The encodings are also as used in the Intel manual, with automated corrections.114// For example, the Intel manual sometimes omits the modrm /r indicator or other trailing bytes,115// and it also contains typographical errors.116// These problems are corrected so that the CSV data may be used to generate117// tools for processing x86 machine code.118// See https://golang.org/x/arch/x86/x86map for one such generator.119//120// Valid32 and Valid64121//122// These columns hold validity abbreviations as defined in the Intel manual:123// V, I, N.E., N.P., N.S., or N.I.124// Tools processing the data are typically only concerned with whether the125// column is "V" (valid) or not.126// This data is also corrected compared to the manual.127// For example, the manual lists many instruction forms using REX bytes128// with an incorrect "V" in the Valid32 column.129//130// CPUID Feature Flags131//132// This column specifies CPUID feature flags that must be present in order133// to use the instruction. If multiple flags are required,134// they are listed separated by plus signs, as in PCLMULQDQ+AVX.135// The column can also list one of the values 486, Pentium, PentiumII, and P6,136// indicating that the instruction was introduced on that architecture version.137//138// Tags139//140// The tag column does not correspond to a traditional column in the Intel manual tables.141// Instead, it is itself a comma-separated list of tags or hints derived by analysis142// of the instruction set or the instruction encodings.143//144// The tags address16, address32, and address64 indicate that the instruction form145// applies when using the specified addressing size. It may therefore be necessary to use an146// address size prefix byte to access the instruction.147// If two address tags are listed, the instruction can be used with either of those148// address sizes. An instruction will never list all three address sizes.149// (In fact, today, no instruction lists two address sizes, but that may change.)150//151// The tags operand16, operand32, and operand64 indicate that the instruction form152// applies when using the specified operand size. It may therefore be necessary to use an153// operand size prefix byte to access the instruction.154// If two operand tags are listed,  the instruction can be used with either of those155// operand sizes. An instruction will never list all three operand sizes.156//157// The tags modrm_regonly or modrm_memonly indicate that the modrm byte's158// r/m encoding must specify a register or memory, respectively.159// Especially in newer instructions, the modrm constraint may be the only way160// to distinguish two instruction forms. For example the MOVHLPS and MOVLPS161// instructions share the same encoding, except that the former requires the162// modrm byte's r/m to indicate a register, while the latter requires it to indicate memory.163//164// The tags pseudo and pseudo64 indicate that this instruction form is redundant165// with others listed in the table and should be ignored when generating disassembly...
