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
