<div>I've been trying all sorts of things to be able to resolve this, but I can't find way to get this done.</div>

<div>Does anyone know how I might introduce a transform at the ASM level?</div>

<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hi,
<div><br>
</div>
<div>Does anyone have any direction for me on testing a back-end pre-emit pass independently of other passes? The pass I'm looking at is a MachineFunctionPass, so the code is already using target-specific instructions.</div>
<div><br>
</div>
<div>What I'm really looking to do is to see that the pass is correctly converting certain target-specific instructions sequences into other sequences, but I'm unsure how I can get an input in the correct format to construct a good unit test. Can I generate
an ".ll" file using target specific instructions and then pass it through to a back-end MachineFunctionPass to test specifically just that one pass?</div>
