Convert vlmul and policy to human readable string, some example below:
Before:
[VALID,Demand
field={1(VL),0(DEMAND_NONZERO_AVL),1(SEW),0(DEMAND_GE_SEW),1(LMUL),0(RATIO),0(TAIL_POLICY),0(MASK_POLICY)}
AVL=(reg:DI 0 zero)
SEW=16,VLMUL=3,RATIO=2,TAIL_POLICY=1,MASK_POLICY=1]
^ ^ ^
After:
[VALID,Demand
field={1(VL),0(DEMAND_NONZERO_AVL),1(SEW),0(DEMAND_GE_SEW),1(LMUL),0(RATIO),0(TAIL_POLICY),0(MASK_POLICY)}
AVL=(reg:DI 0 zero)
SEW=16,VLMUL=m8,RATIO=2,TAIL_POLICY=agnostic,MASK_POLICY=agnostic]
^^ ^^^^^^^^ ^^^^^^^^
gcc/ChangeLog:
* config/riscv/riscv-vsetvl.cc (vlmul_to_str): New.
(policy_to_str): New.
(vector_insn_info::dump): Use vlmul_to_str and policy_to_str.
OK
