Replacing a function from one module into another one
...teBody();
llvm::ValueToValueMapTy VMap;
populateVMap(VMap, fOld, fNew);
bool ModuleArg = true;

fOld->setPersonalityFn(llvm::MapValue(fNew->getPersonalityFn(), VMap));
But after running the code, I still get the error: *Use still stuck around
after Def is destroyed*
Which means that the instructions moved from *fNew* still refer to the
arguments of *fNew* instead of the "mapped" (supposedly) ones in *fOld*. I
have some ideas of what could b...

Register Dataflow Analysis on X86
Hi Scott,
Sorry for the late reply, I was out of office during the holidays.
1. A def node can reach either a use node, or another def node. In the highlighted phi node (p3224), the def (d3225) reaches another def (1598) in statement (s1597), that’s why it’s needed.
2. The reason why the def of R11 in s1578 is not connected directly to the use in s1725 is that there may be an intervening

Replacing a function from one module into another one
Hi Philip,
Thank you very much for your answer, the vector declaration example worked.
I'm pretty sure the ValueToValueMapTy is the last thing I need because I
even saw there is another function that could help me llvm*:*:RemapFunction
<http://llvm.org/doxygen/namespacellvm.html#addf0183e92893bdbcde00fc9091dda93>;
but my problem is that I don't know how to populate the
