<p style="margin: 0px;">Hi everyone,</p>
<p style="margin: 0px;">I made some fixes to the compiler when it comes to SSE and AVX instructions that deal with single (rather than packed) data, since it got the memory sizes wrong and assumed they were 128-bit or 256-bit instead. Thanks to Marco for pointing out that it was single data in issue #32219 - I completely overlooked that.</p>
<p style="margin: 0px;">Details and patches are here: <a class="moz-txt-link-freetext" href="https://bugs.freepascal.org/view.php?id=35700">https://bugs.freepascal.org/view.php?id=35700</a></p>
<p style="margin: 0px;">What it means is that the following will now compile without any warnings or errors on i386 and x86_64:</p>
<pre class="bug-attachment-preview-text">ADDSD XMM0, QWORD PTR [EAX] ADDSD XMM0, [EAX] ADDSD XMM0, VarOfTypeDouble</pre>
<p style="margin: 0px;">And with other instructions of a similar format.</p>
