rvda
RISC-V Disassembler
usage
code
isa, _ := rvda.New(32, rvda.RV32gc)
fmt.Printf("isa: %s\n", isa)
addr := uint(0xdeadbeef)
ins := uint(0x483f8297)
da := isa.Disassemble(addr, ins)
fmt.Printf("decode: %#v\n", da)
fmt.Printf("string: %s\n", da)
output
isa: RV32 ext "acdfim"
decode: &rvda.Disassembly{Addr:0xdeadbeef, AddrLength:0x20, Ins:0x483f8297, InsLength:0x4, Assembly:"auipc t0,0x483f8"}
string: deadbeef: 483f8297 auipc t0,0x483f8

Types ¶
type Disassembly ¶
type Disassembly struct {
Addr uint // address
AddrLength uint // address length in bits
Ins uint // instruction
InsLength uint // instruction length in bytes
Assembly string
}
Disassembly returns the result of the disassembler call.
func (*Disassembly) String ¶
func (da *Disassembly) String() string
type ISA ¶
type ISA struct {
// contains filtered or unexported fields
}
ISA is an instruction set
func (*ISA) Disassemble ¶
func (isa *ISA) Disassemble(addr, ins uint) *Disassembly
Disassemble a RISC-V instruction at the address.
func (*ISA) GetExtensions ¶
GetExtensions returns the ISA extension bits.
