package x86csv

import "golang.org/x/arch/x86/x86csv"

Package x86csv provides means to work with "x86.csv". Only latest version of "x86.csv" format is supported.

Terminology: 

given "OPCODE [ARGS...]" line;

Opcode - instruction name/mnemonic/class. Args - instruction operands. Syntax - Opcode with Args.

type Inst Uses

❖
type Inst struct {
    // Intel syntax (example: "SHR r/m32, imm8").
    Intel string

    // Go assembler syntax (example: "SHRL imm8, r/m32").
    Go  string

    // GNU binutils syntax (example: "shrl imm8, r/m32").
    GNU string

    // Binary encoding (example: "C1 /4 ib").
    Encoding string

    // Validity in 32bit mode ("V", "I" or "N.E.").
    Mode32 string

    // Validity in 64bit mode ("V", "I", "N.E.", "N.P.", "N.I." or "N.S.").
    Mode64 string

    // CPUID feature flags required (comma-separated).
    CPUID string

    // Hints about instruction (comma-separated).
    // See "x86spec" package to see detailed overview of possible
    // tags and their meaning.
    Tags string

    // Read/write action of the instruction on its arguments, in Intel order.
    // For example, "rw,r" denotes that "SHR r/m32, imm8" reads and writes
    // its first argument but only reads its second argument.
    Action string

    // Whether Intel syntax has encoding forms distinguished only by
    // operand size, like most arithmetic instructions ("" or "Y").
    Multisize string

    // DataSize is the size of the data operation in bits ("8" for MOVB, "16" for MOVW, and so on).
    DataSize string
}

An Inst describes single x86 instruction encoding form.

func (*Inst) GNUArgs Uses

❖
func (inst *Inst) GNUArgs() []string

GNUArgs returns the arguments in GNU binutils (mostly AT&T) syntax.

func (*Inst) GNUOpcode Uses

❖
func (inst *Inst) GNUOpcode() string

GNUOpcode returns the opcode in GNU binutils (mostly AT&T) syntax.

func (*Inst) GoArgs Uses

❖
func (inst *Inst) GoArgs() []string

GoArgs returns the arguments in Go (Plan9) syntax.

func (*Inst) GoOpcode Uses

❖
func (inst *Inst) GoOpcode() string

GoOpcode returns the opcode in Go (Plan9) syntax.

func (*Inst) HasTag Uses

❖
func (inst *Inst) HasTag(tag string) bool

HasTag reports whether inst tag list contains the specified tag.

func (*Inst) IntelArgs Uses

❖
func (inst *Inst) IntelArgs() []string

IntelArgs returns the arguments in the Intel syntax.

func (*Inst) IntelOpcode Uses

❖
func (inst *Inst) IntelOpcode() string

IntelOpcode returns the opcode in the Intel syntax.

type Reader Uses

❖
type Reader struct {
    // contains filtered or unexported fields
}

A Reader reads entries from an "x86.csv" file.

func NewReader Uses

❖
func NewReader(r io.Reader) *Reader

NewReader returns a Reader reading from r, which should be of the content of the "x86.csv" (format version=0.2).

func (*Reader) Read Uses

❖
func (r *Reader) Read() (*Inst, error)

Read reads and returns the next Row from the "x86.csv" file. If there is no data left to be read, Read returns {nil, io.EOF}.

func (*Reader) ReadAll Uses

❖
func (r *Reader) ReadAll() ([]*Inst, error)

ReadAll reads all remaining rows from r.

If error is occured, still returns all rows that have been read during method execution.

A successful call returns err == nil, not err == io.EOF. Because ReadAll is defined to read until EOF, it does not treat end of file as an error to be reported.
