I installed a custom version of spike:

git clone https://github.com/nthu-pllab/riscv-isa-sim.git
cd riscv-isa-sim

mkdir build && cd build
../configure 
  --prefix=$RISCV 
  --with-isa=RV64IMAFDCV 
  --with-varch=vlen:1024,elen:64
make -j`nproc` install

And installed pk:

git clone https://github.com/riscv/riscv-pk.git
cd riscv-pk

mkdir build && cd build
../configure 
  --prefix=$RISCV 
  --with-arch=rv64gcv 
  --with-abi=lp64d 
  --host=riscv64-unknown-elf

make -j`nproc` install

However, I got a warning without the expected output:

git clone https://github.com/riscv-non-isa/rvv-intrinsic-doc.git
cd rvv-intrinsic-doc/examples
clang 
  --target=riscv64-unknown-elf 
  --sysroot=$RISCV/riscv64-unknown-elf 
  --gcc-toolchain=$RISCV 
  -march=rv64gcv1p0 
  rvv_saxpy.c -o rvv_saxpy

spike --isa=RV64GCV_zfh_zvfh --varch=vlen:128,elen:64 pk rvv_saxpy

<stdin>:25.39-29.9: Warning (interrupt_provider): /cpus/cpu@0/interrupt-controller: Missing #address-cells in interrupt provider
<stdin>:25.39-29.9: Warning (interrupt_provider): /cpus/cpu@0/interrupt-controller: Missing #address-cells in interrupt provider

spike pk yields the same warnings. How can I this warning be fixed?

Google tells me the following issue:

https://github.com/riscv-software-src/riscv-isa-sim/issues/784

However, I didn’t see any information after Missing #address-cells in interrupt provider. Also, my colleague runs spike pk perfectly without warnings.
