Crate disc_v 

A RISC-V disassembler.

Supports RV32, RV64 and RV128 with the I, M, A, F, D, Q and C extensions, Zicsr, Zifencei, and the bit-manipulation extensions Zba, Zbb, Zbc and Zbs. The text follows GNU objdump’s for a raw binary (objdump -D -b binary), so branch targets are written as 0x1008.

use disc_v::{disassemble, Isa};

let code = [0x13, 0x05, 0x10, 0x00, 0x82, 0x80]; // li a0,1; ret
for ins in disassemble(Isa::Rv64, 0x1000, &code) {
    println!("{:x}: {ins}", ins.pc());
}

Structs

Disassembler

An iterator over the instructions in a byte slice. Create one with disassemble.

Instruction

A decoded instruction.

Operands

The operands of an instruction, formatted as objdump does: a0,8(sp).

Enums

Isa

The base integer ISA, which determines the register width and which encodings are valid.

Functions

decode

Decodes the instruction inst, located at address pc.

decode_bytes

Decodes the instruction at the start of bytes, located at address pc.

disassemble

Disassembles bytes, the first of which is at address pc.

inst_length

Returns the length in bytes of the instruction whose first 16-bit parcel is parcel, or None for the reserved lengths of 10 bytes or more.
