A dynamic linker with lazy binding support may need to handle variant PCS function symbols specially, so an ELF symbol table marking STO_AARCH64_VARIANT_PCS [1] was added to address this. Function symbols that follow the vector PCS are marked via the .variant_pcs assembler directive, which takes a single parameter specifying the symbol name and sets the STO_AARCH64_VARIANT_PCS st_other flag in the object file.
