In the RISC-V architecture, you have excellent support for embedding information into code by choosing compressed or uncompressed instructions. While being a typical RISC with fixed 32-bit instruction length, RISC-V allows certain common instructions to be encoded as compressed 16-bit instructions to improve code density. Each compressed instruction has a functionally identical 32-bit cousin. If you are interested in how that is used to embed information into a binary, you can check out my x8...
