New Revision: f03609b5c7531061be659e36824d37ef86a1fdf4
URL: https://github.com/llvm/llvm-project/commit/f03609b5c7531061be659e36824d37ef86a1fdf4
DIFF: https://github.com/llvm/llvm-project/commit/f03609b5c7531061be659e36824d37ef86a1fdf4.diff
LOG: [RISCV] V does not imply F.
If users want to use vector floating point instructions, they need to
specify 'F' extension additionally.
