Hi,

This small series introduces the same CPU detection and assembler macros
as the earlier V extension stuff but sticking to a scalar use case.

Benchmark results are included in the last patch.

----------------------------------------------------------------
Rémi Denis-Courmont (3):
      lavu: detect RISC-V F extension (i.e. float)
      lavu/riscv: initial common header for assembler macros
      lavc/audiodsp: add RISC-V F float vector clip
