But when I run mem2reg, I'm getting values with valueTy set to 32, which is not in the ValuTy enum. I deduced those are instruction values. But I didn't find that much doc on those. That's why I'd like to stay in the "safe" zone and avoiding those vals.<br><br>Thanks again. <br><br>Regis<br></div></div><div dir="ltr"><hr><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">De : </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:james@jamesmolloy.co.uk">James Molloy</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Envoyé : </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">29/08/2015 12:49</span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">À : </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;"><a href="mailto:regis.portalez@altimesh.com">Régis Portalez</a>; <a href="mailto:llvm-dev@lists.llvm.org">llvm-dev@lists.llvm.org</a></span><br><span style="font-family: Calibri,sans-serif; font-size: 11pt; font-weight: bold;">Objet : </span><span style="font-family: Calibri,sans-serif; font-size: 11pt;">Re: [llvm-dev] Llvm pass to remove temporaries</span><br><br></div><div dir="ltr">Hi,<div><br></div><div>mem2reg is what you want.
