A JVM in Rust part 5 – Executing instructions
Take it full circle. Minecraft running Terraria emulating a 32-bit RISC-V CPU running Pong written in Rust - someone already did the latter part I believe, https://youtu.be/zXPiqk0-zDY?si=M0IHSzRLkaddwwKC

Someone crafted a redstone PC in Minecraft to play Minecraft inside Minecraft
I found the Terraria version more impressive: https://youtu.be/zXPiqk0-zDY

I have written a JVM in Rust
Seems like that would take care of roots for the bytecode's themselves, but not for "native" functions[1]. Allocating a new object could call gc[2], and native functions are using the native callstack. It seems like it would be easy to allocate in a native function and any unrooted references would be invalidated. In fact I see a case like that here[3]. That method creates a reference with `expect_concrete_object_at` and then calls gc with `new_java_lang_class_object`. It avoids UB by not using `arg` after the call that gc's, but there is nothing stopping you from using `arg` again (and having an invalid reference).
