[PATCH] D84397: [MSP430] Replace known epilogues with branches to __mspabi_func_epilog_N

[Anton Korobeynikov via Phabricator via llvm-commits]

asl added inline comments.


================
Comment at: llvm/lib/Target/MSP430/MSP430CommonEpilogueOptimizer.cpp:151
+    // Prevent ++It when It points to just removed terminator instruction
+    std::vector<MachineBasicBlock::iterator> OriginalTerminators(
+        MBB.getFirstTerminator(), MBB.end());
----------------
You don't need this. Just do std::next / std::prev prior to changing the iterators.
