I have some little of weird tests. Compile 32 bit baremetal benchmarks, such as dhrystone and coremark, and run them on qemu-system-riscv64. These tests can pass. These tests cases cover the most of instruction translation. I think some assembling test cases covering XLEN change are also needed. Not yet.
