Hello. Nice test. Thanks for putting it together. LGTM



================
Comment at: llvm/test/CodeGen/ARM/peephole-callee-save-regalloc.mir:8
+# Check that register class for %5 is unchanged as 'tcgpr'
+# CHECK: { id: 5, class: tcgpr, preferred-register: '' }
+
----------------
Can you add a CHECK line for TCRETURNri, to show it's still using %5
