A JVM in Rust part 5 – Executing instructions

  A tiny JVM written in Rust. Learning project

  Your understanding of Rust is correct, but the code uses unsafe: https://github.com/andreabergia/rjvm/blob/93e7e48db085e780b0...

  As a result, when the VM gets dropped, the memory gets deallocated even if there are still objects that reference it.

  A fully compliant RISC-V computer made inside the game Terraria

  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

  GraalVM compiles Java applications into native executables that start instantly, scale fast, and use fewer compute resources 🚀

  

  Why would they? The direction for safer JVM research is to implement JVMs in Java, which has the advantage of being both memory safe outside a few tiny core areas (same as rust) whilst having cleaner code than the Rust impl (none of these problems with lifetimes).
