--- Comment #12 from Andrew Macleod <amacleod at redhat dot com> 2012-01-26 13:57:56 UTC --- (In reply to comment #11) > What about the other files that use __sync_* in libstdc++? I would change the bare minimum... Every change is a risk of some sort this late n the game. The only reason to consider this change was the unacceptable performance regression on power which was reported. If it hasn't been reported, I'd leave it alone personally :-) I hope to replace *all* __sync calls everywhere in the toolchain with __atomic for 4.8. That way there is also time to evaluate the proper model for each one and test it.
