You need to modify the lowering for COPY_STRUCT_BYVAL_I32 in a few more places. We should be using the thumb1 opcodes for all the instructions generated by the lowering. You have handled the load/store case for the values, but you still need to take care of the constant pool load, the subtract (for the loop counter) and the branch.

Please also check that your patch works with the test case I uploaded to that bug (also attached to this email). In addition to checks for thumb1, this test case also exposes a bug in the current code with the thumb2 lowering. It will trigger an assertion because an operand is added to a full instruction.
