We also have a more sophisticated motivation behind this change. In the future we might need to export riscv_cpu_options[] to other files, and ARRAY_LIST() doesn't work properly in that case because the array size isn't exposed to the header file. Here's a future sight of what we would deal with: ./target/riscv/kvm.c:1057:5: error: nested extern declaration of 'riscv_cpu= _add_misa_properties' [-Werror=3Dnested-externs] n file included from ../target/riscv/kvm.c:19: home/danielhb/work/qemu/include/qemu/osdep.h:473:31: error: invalid applica= tion of 'sizeof' to incomplete type 'const RISCVCPUMultiExtConfig[]' 473 | #define ARRAY_SIZE(x) ((sizeof(x) / sizeof((x)[0])) + \ | ^ ./target/riscv/kvm.c:1047:29: note: in expansion of macro 'ARRAY_SIZE' 1047 | for (int i =3D 0; i < ARRAY_SIZE(_array); i++) { \ | ^~~~~~~~~~ ./target/riscv/kvm.c:1059:5: note: in expansion of macro 'ADD_UNAVAIL_KVM_P= ROP_ARRAY' 1059 | ADD_UNAVAIL_KVM_PROP_ARRAY(obj, riscv_cpu_extensions); | ^~~~~~~~~~~~~~~~~~~~~~~~~~ home/danielhb/work/qemu/include/qemu/osdep.h:473:31: error: invalid applica= tion of 'sizeof' to incomplete type 'const RISCVCPUMultiExtConfig[]' 473 | #define ARRAY_SIZE(x) ((sizeof(x) / sizeof((x)[0])) + \ | ^ ./target/riscv/kvm.c:1047:29: note: in expansion of macro 'ARRAY_SIZE' 1047 | for (int i =3D 0; i < ARRAY_SIZE(_array); i++) { \ Homogenize the present and change the future by using DEFINE_PROP_END_OF_LIST() in riscv_cpu_options[].
