9.51.2.2 Relocations
....................
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.
