If swap8 is an alias to rev8.h, then swap16 should be an alias to rev16 (rv32) or rev16.w (rv64) because it simplifies compiler.
If swap8 is no more a legal insn name, swap16 should be also removed.

Here's a good example. The cycle CSR is defined as 64-bit which is fine but it isn't made clear that reading from 0xc00 returns the least-significant 32 bits. Also, the cycleh CSR is defined as 32-bit…

NEMU貌似没有为riscv32e单独配置一个完整的环境
1. nemu缺少`configs/riscv32e-am_defconfig`
2. menuconfig配置RVE选项，编译结果依然为`riscv32-nemu-interpreter`，在riscv32e情况下会使`am-kernels/kernels/nemu`编译出`riscv32-nemu-interpreter-ris…
