Special relocations are available by using the ‘ @ plt ’, ‘ @ got ’, or ‘ @ got ’ suffixes after a constant expression, which correspond to the R_ASMJS_LEB128_PLT, R_ASMJS_LEB128_GOT, and R_ASMJS_LEB128_GOT_CODE relocations, respectively.

The ‘ @ plt ’ suffix is followed by a symbol name in braces; the symbol value is used to determine the function signature for which a PLT stub is generated. Currently, the symbol name is parsed from its last ‘ F ’ character to determine the argument count of the function, which is also necessary for generating a PLT stub.
