Thanks for reviewing again. I have fixed the typos in the comments, changed the variable name, and modified the test case. Regarding the predicated MOVs I have taken a slightly different approach. Since we only want to do this peephole optimisation for Thumb1, I first check that the instruction is actually a Thumb1 instruction. And because Thumb1 does not have conditional movs, we can safely omit the isPredicated check (testing shows no issues).
