<p class="MsoNormal">I am experiencing problems, when trying to assemble these two x86-64 Opcodes<o:p></o:p></p>
<p class="MsoNormal">“add r64, imm32”<o:p></o:p></p>
<p class="MsoNormal">“imul r64, r64, imm32”<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When having the most significant bit set for imm32, for example:<o:p></o:p></p>
<p class="MsoNormal">“add rax, 0x80000000”, “add rax, 0xffffffff”, …<o:p></o:p></p>
<p class="MsoNormal">“imul rbx, rsi, 0x80000000”, “imul rbx, rsi, 0xffffffff”, …<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Error Message I receive is the following:<o:p></o:p></p>
<p class="MsoNormal">„Instruction:1:1: error: invalid operand for instruction“<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I was using the MCAsmParser, with the RelaxAll Flag set to true, for the MCStreamer.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can someone clarify, as to why this is happening, or what I am missing?<o:p></o:p></p>
<p class="MsoNormal">Thank you in advance.<o:p></o:p></p>
