    I added my custom instrumentation backend pass for ARM cortex-m33 CPU at the end of the `addPreEmitPass2()` function which is after `ARMConstantIslandPass`. In my custom pass, I do some instrumentation so the function size increases. My guess is as the function size increases the constant addresses go out of range for instructions such as ` vldr d11, [pc, #1008]` . The highest `pc` relative access I found is 1008 without instrumentation and with my instrumentation it will be higher than 1020 (maximum limit?).

As a result, I am getting  **error: out of range pc-relative fixup value**. Can you please suggest to me how this is fixable?
