Duplicate Case Item in riscv_tracer.sv

DSIM is reporting a duplicate case item in riscv_tracer.sv. I do not see this warning with xrun, but inspection shows it to be a real item. Details below: URL: https://github.com/openhwgroup/cv32e40p Branch: master Hash: de826243 Path: rtl/riscv_tracer.sv, lines 645, 646.

// set mnemonic
case (instr[31:26])
// skipping lines 624..642
   // shuffle/pack
   6'b110000: begin mnemonic = "pv.shuffle";   end
   6'b110000: begin mnemonic = "pv.shufflei0"; str_imm = $sformatf("0x%0d", imm_shuffle_type);  end
   6'b111010: begin mnemonic = "pv.shufflei1"; str_imm = $sformatf("0x%0d", imm_shuffle_type);  end

To Reproduce:

Run the comp rule (clones the RTL, compiles, and quits).

$ git clone https://github.com/openhwgroup/core-v-verif
$ cd core-v-verif/cv32/sim/uvmt_cv32
$ make SIMULATOR=dsim comp
