### Describe the usage question you have. Please include as many useful details as possible. Arrow is employed in CEPH software defined storage (https://github.com/ceph/ceph, https://github.com/ceph/ceph/blob/main/.gitmodules): ``` [submodule "src/arrow"] path = src/arrow url = https://github.com/apache/arrow.git ``` Building the whole system at s390x with the -Werror triggers the following: arrow/cpp/src/arrow/util/cpu_info.cc:155:3: error: statement has no effect [-Werror=unused-value] (347a88ff9d20e2a4061eec0b455b8ea1aa8335dc). Should a "dummy" default element be inserted into the `flag_mappings[]` : ``` struct { std::string name; int64_t flag; } flag_mappings[] = { #if (defined(__i386) || defined(_M_IX86) || defined(__x86_64__) || defined(_M_X64)) {"ssse3", CpuInfo::SSSE3}, {"sse4_1", CpuInfo::SSE4_1}, {"sse4_2", CpuInfo::SSE4_2}, {"popcnt", CpuInfo::POPCNT}, {"avx", CpuInfo::AVX}, {"avx2", CpuInfo::AVX2}, {"avx512f", CpuInfo::AVX512F}, {"avx512cd", CpuInfo::AVX512CD}, {"avx512vl", CpuInfo::AVX512VL}, {"avx512dq", CpuInfo::AVX512DQ}, {"avx512bw", CpuInfo::AVX512BW}, {"bmi1", CpuInfo::BMI1}, {"bmi2", CpuInfo::BMI2}, #endif #if defined(__aarch64__) {"asimd", CpuInfo::ASIMD}, #endif }; ``` Thank you! ### Component(s) C++ -- This is an automated message from the Apache Git Service.
