[LLVMdev] CFG leaf node
Hi, guys.
Is there any easy way to know the leaf BB node in the CFG which is not terminated by such a 'br' instruction?
E.g., for the following LLVM assembly:
-----------------------------------------------------------
int %foo2(int %k) {
entry:
br label %bb
bb: ; preds = %bb, %entry
%indvar = phi uint [ 0, %entry ], [ %indvar.next, %bb ] ;
