Hi, Ma Jin

     1. There are few developments since May in GCC because the spec of 
Zfbf <https://github.com/riscv/riscv-bfloat16> is constantly changing.

     2. We (PLCT lab) will implement Zvfbfmin and Zvfbfwma after Zvfh 
has been merged in GCC.

     3. I will send a patch to support bfloat16_t in RISC-V port, but 
Zfbf extension's patch will be sent after it released.
