<div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif">Thanks Tim. You are right and sorry for my typo. Another related question is some sub-instruction class override it by let expression, as `let InOperanList=ins` and some others seem redeclare it, such as `dag InOperandList = ins`. What's the different between these 2 usages?</div>

</div></div>Do you mean InOperandList and OutOperandList? They're used by TableGen<br>
for many of its automatically generated code fragments (all three of<br>
asm parsing, disassembly, codegen). The place to look for uses is<br>
utils/TableGen/*.cpp.<br>
