lavu/riscv: fixed vector sum-and-difference with RVV (2022-09-06 21:30:28
+0300)
Changes since v2:
- Add fixed butterflies (the only fixed point DSP function if !USE_FIXED).
- Clean up CPU flags definition.
- Move ISA extension selection to function macro.
- Add const macro (currently unused).
- Add checkasm support.
- Use ARM-like macros for FP ABIs.
This patchset is orthogonal to the RISC-V scalar patchset. They can be merged
in any order.
