postmodern<p>Fun Assembly Factoid: you can express SIB memory offsets without a base register and use the displacement as a fixed address. I believe this was a shellcode technique back in the days before ASLR.</p><pre><code>movl 0x41414141(,esi,4), %eax<br></code></pre><p>You can even dereference exact addresses:</p><pre><code>movl (0x41414141), %eax<br></code></pre><p>The GNU assembler will accept both of these syntaxes. However, GNU <code>objdump -d -M i386</code> will disassemble the generated opcodes (<code>a1 41 41 41 41</code>, <code>a1</code> being the opcode for <code>mov moffset32, reg32</code>) as <code>mov 0x41414141,%eax</code>. If you specify <code>-M intel</code> for Intel syntax, you however get <code>mov eax,ds:0x41414141</code>. Not sure if this is a bug?</p><p><a href="https://infosec.exchange/tags/assembly" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>assembly</span></a> <a href="https://infosec.exchange/tags/asm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>asm</span></a></p>
