ruapu determines whether the CPU supports certain instruction sets by trying to execute instructions and detecting whether an `Illegal Instruction` exception occurs. ruapu does not rely on the cpuid instructions and registers related to the CPU architecture, nor does it rely on the `MISA` information and system calls of the operating system. This can help us get more detailed CPU ISA information. ruapu determines whether the CPU supports certain instruction sets by trying to execute instructions and detecting whether an `Illegal Instruction` exception occurs. ruapu does not rely on the cpuid instructions and registers related to the CPU architecture, nor does it rely on the `MISA` information and system calls of the operating system.
