<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m trying to write a custom module-level pass that runs before AsmPrinter::EmitStartOfAsmFile(), since I’d like to have some processed information available once entering this function.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Looking through “Writing an LLVM pass” documentation, it’s not clear to me if this is possible. I’ve also tried putting the pass in different orders (addPreISel, addIRPasses, and etc.). Am I missing something or this is just not possible
to do? Any help is appreciated.<o:p></o:p></p>
