Mikael Pettersson <mikpe at it dot uu.se> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |FIXED --- Comment #1 from Mikael Pettersson <mikpe at it dot uu.se> 2012-12-09 10:18:04 UTC --- A recent trunk (r194325) generates identical object code for both functions. I'm assuming the switch to LRA for x86_64 resolved the issue. Closing as fixed.
