...rather than converting > them back and forth. With both I assume you mean both GEP instrs and GEP constantexprs? If so then yes, I am intending to make it work with both, and that's exactly why I need to convert the constantexprs to instructions (Since, unless I'm very much mistaken, a gepconstantexpr won't work with an alloca, so I can't leave them intact).

Hi, I've been struggling with constantexprs for a bit. I'm working on a pass that transforms global variables to local variables, and in particular the GetElementPtrConstantExpr is a bit troublesome. For my transformation to properly work, a global value should only be used by Instructions, not by ConstantExprs. I was thinking to add a ConstantExpr::replaceWithInstr() virtual method,

What do you mean? A constantexpr gep can be used as the size of an alloca. -Chris
