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.
