<p style="margin-top:0;margin-bottom:0">I believe LONGINT should be 64-aligned on 32-bit x86 so for example you can use InterlockedCompareExchange64 on it.</p>
<p style="margin-top:0;margin-bottom:0">I suggest LONGINT should be 64-aligned so maybe all targets have the same layout, in general.</p>

<br>
Do we support, or does there even exist, a target that has 32-bit native words,<br>
but has some instruction or other reason why some operand would need to be<br>
64-bit aligned?<br>
<br>
We appear to be 64-bit aligning LONGINT and big enough subranges thereof on<br>
32-bit targets, which then needs to propagate through records, arrays, and objects<br>
that contain them, as well as all heap allocated objects, stack frames, etc.<br>
