We should do something similar to how other PIC addresses are handled. ^ permalink raw reply [flat|nested] 3+ messages in thread

I wonder if it would handle coroutines correctly. Clang has this open bug https://github.com/llvm/llvm-project/issues/47179 that is related to this optimization. ^ permalink raw reply [flat|nested] 3+ messages in thread
