Compare currently GCC and LLVM performance difference using FFmpeg as benchmark.
Tested on a RISC-V develop board, contains vectorization performance improvement results.
We will introduce how to use FFmpeg as a benchmark, to compare GCC and LLVM
performance on it with different situation.
The test is mainly based on the RISC-V development board Muse Pi Pro with RVV1.0 feature.
In addition, some problems that need to be solved will also be briefly introduced.
