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.
