It is the second compression type, after the existing ELFCOMPRESS_ZLIB. Zstd generally provides a compelling tradeoff of speed and compression (other algorithms may compress slightly better but take a lot longer, or run faster but do not compress nearly as well). See https://groups.google.com/g/generic-abi/c/satyPkuMisk for details. ELFCOMPRESS_ZSTD will be supported in a future Clang/LLVM update. ELF Tool Chain tools also need updating.
