Zig Aarch64 Disassembler

Inspired by zig-dis-x86_64.

Using LLVM's disassembly tests.

Usage

Programmatic Disassembly:

const std = @import("std");
const Disassembler = @import("zig-dis-aarch64").Disassembler;

var disassembler = Disassembler.init(&.{
    0x41, 0x00, 0x03, 0x1a,  // adc w1, w2, w3
    0x41, 0x00, 0x03, 0x9a,  // adc x1, x2, x3
});

var text = std.ArrayList(u8).init(gpa);
defer text.deinit();

while (try disassembler.next()) |inst| {
    try inst.fmtPrint(text.writer());
    try text.append('\n');
}

try std.testing.expectEqualStrings(
    \\adc w1, w2, w3
    \\adc x1, x2, x3
    \\
, text.items);
