# The targets are chosen to prevent the generated machine code from using any

#
# - `x86_64-unknown-none` satisfies this property, as explained by [the
# official documentation](https://doc.rust-lang.org/rustc/platform-support/x86_64-unknown-none.html).
# - `riscv64imac-unknown-none-elf` denotes a RISC-V ISA with only basic
# extensions (`imac`) and no floating-point-related extensions.
# - `loongarch64-unknown-none-softfloat` is rather self-explaining.
