Hi,
the patch below is my attempt at properly deprecating switch
-fipa-cp-alignment. I have not found any clear example to follow but
hopefully I have not missed anything. If so, please let me know.
So far I have only tested this with a normal build and "make info" but
I will give it a proper bootstrap before committing if ACKed. OK for
trunk as it is?
Thanks,
Martin
