Description Tom Browder 2010-09-06 13:25:13 UTC 
The "-fipa-sra" option may result in object code changes.  Users should be notified of such changes so they can make source code changes.

It would be nice but sometimes it is not the right thing to do because of virtual functions, default arguments, etc.

Could you give an example testcase that exhibits the changes you're worried about?

Guess not; closing. Feel free to reopen if you come up with one.
