[IndVarSimplify] Narrow IV's are not eliminated resulting in inefficient code
Hi,
Would you be able to kindly check and assist with the IndVarSimplify / SCEV
problem I got in the latest LLVM, please?
Sometimes IndVarSimplify may not eliminate narrow IV's when there actually
exists such a possibility. This may affect other LLVM passes and result in
inefficient code. The reproducing test 'indvar_test.cpp' is attached.
The problem is with the second

Dear All,
Is the following patch to ScalarEvolution correct? It seems that
without it, the enclosing for loop could skip over SCEVAddRecExpr's in
