I've made a RiscPC emulator in the browser using QEMU and WASM. It boots Linux kernels and currently emulates a StrongARM RiscPC: https://github.com/kmehltretter82/risc_pc_linux_emu I used LLMs a lot while building it. Your GCC work looks useful for this. I will look at building the RiscPC Linux kernel with it, and at emulating the original ARMv3 CPU too. Thanks, Karl
