| Special relocations are available by using the ‘<samp><span class="samp">@</span><var>plt</var></samp>’, |
| ‘<samp><span class="samp">@</span><var>got</var></samp>’, or ‘<samp><span class="samp">@</span><var>got</var></samp>’ 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. |
| |
| <p>The ‘<samp><span class="samp">@</span><var>plt</var></samp>’ 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 <em>name</em> is parsed |
| from its last ‘<samp><span class="samp">F</span></samp>’ character to determine the argument count of |
| the function, which is also necessary for generating a PLT stub. |
