--- Comment #14 from Vineet Gupta <vineetg at gcc dot gnu.org> ---
To summarize this needs following 3 things
1. preprocessor macro __riscv_v_fixed_vlen if -march has explicit xxxvl
specified
2. implement gcc toggle -mrvv-vector-bits=zvl which essentially copies the xxx
from -march string
3. Implement attribute riscv_rvv_vector_bits to specify vector length for user
