I am writing an llvm pass wherein I require to iterate MachineBasicBlocks in reverse. The ilist reverse_iterator is not functioning as expected. Nor is the ilist iterator working
in reverse (although – operator is overloaded to do so).
for (MachineFunction::iterator MBBI = mf_->end(), E = mf_->begin();MBBI != E; --MBBI)
MachineBasicBlock *MBB = MBBI;
Any suggestion would be helpful.
