Could you build this?
No Developing a CPU userspace instruction set emulator requires profound low-level systems programming, assembly translation, and CPU architecture expertise.
What it would actually take: Implemented in C or Rust, requiring an instruction decoder, register file state machine, and userspace Linux syscall translation layer targeting the LoongArch64 ISA (similar to QEMU userspace emulation). The primary difficulty lies in cycle/instruction decoding accuracy, memory virtualization, and binary translation (JIT/interpreter). Deep understanding of computer architecture, operating system ABI boundaries, and low-level assembly is mandatory.
Discussion
12 comments analyzed.
Competitors mentioned: WASM for game scripting, Lua, libriscv (more flexible alternative), QEMU
Concerns raised: Why is CPU emulation suitable for game engine scripting vs alternatives, High latency cost of calling into scripting solutions, Complex to implement kernel personality and Solaris compatibility, Issues running Go programs in libloong
Feature requests: Support for Go programs in libloong, Dynamic ELF loading capabilities, Transparent CPU emulation similar to FreeBSD/NetBSD compat approach, SPARC/Solaris binary compatibility, LoongArch architecture support
