[LLVMdev] get LPPassManager to use it in llvm::CloneLoop
Hi,
I try to write a FunctionPass that, among other tasks, has to clone some loops
from the current function.
How can I obtain the LPPassManager in order to use the CloneLoop function.
In a LoopPass this is a parameter for the runOnLoop, but how can I obtain it in
a FunctionPass?
I tried simply by creating a new instance :
ValueMap<const Value *, Value* > VMap;
LoopInfo *LI = &getAnalysis<LoopInfo>();
LPPassManager *LPM = ne...

[LLVMdev] get LPPassManager to use it in llvm::CloneLoop
Thanks , your suggestion was welcome and CloneLoop works without passing the
LPPassManager.
However, I reached another problem. When the loop to be cloned has some
subloops, the subloops are not properly cloned. Some clones of the clones are
created and the CFG between the cloned basic blocks of the subloops is not
correctly built. There...

Hi Eli,

maybe CloneLoop should be removed then?
Ciao, Duncan.

How to make ScalarEvolution recompute SCEV values?
...calling the *runOnFunction* from the ScalarEvolution pass, but that also didn't work.
My question is: how can I make ScalarEvolution re-calculate the SCEV values for the unknown SCEVs, or, is there a way to re-run ScalarEvolution and LoopInfo analysis pass during my pass?
This is my current CloneLoop function:
Loop *cloneLoop(Function *F, Loop *L, LoopInfo *LI, const Twine &NameSuffix,
ValueToValueMapTy &VMap) {
// original preheader of the loop
const auto PreHeader = L->getLoopPreheader();
// keep track of the original predecessors
std::set...
