I'm looking for a very minimalistic ARM64 instruction length disassembler, so I can traverse through some instructions of a function.
I need a standalone function without many dependencies, because I need it for a kernel driver.

For x64 I was using .cpp but I can't find something like it for AArch64. There's some full disassembly libraries, but they come with a ton of source code and user land dependencies.

I don't even need support for any of the extension instruction sets like SVE

Every AArch64 instruction is 4 bytes long, naturally aligned.

There isn't an equivalent of Thumb mode compressed instructions for it (yet?), so you don't even have to look at the machine-code bytes to find instruction boundaries.
