Feels like the startup code should actually verify that it's running on a suitable CPU rather than just crashing. I don't think C/C++ or Rust do this either but they should!

pretty much no language do this by default. however, most languages target the -v1 instruction set in 'release' or optimized mode. (e.g. Rust does this, and AFAIK GCC and clang both do this for C/C++)
