I agree that this change won't help PowerPC. As you say, it is primarily helpful to CISC processors (x86, x86-64, mainframe, m68000, ...). Although there do appear to be places in the kernel where volatile is overused and abused, it would still be good to fix this bug. > (In reply to comment #12) > > Please accept my apologies for skipping that step -- I wasn't aware of > > this. > > Should I replicate this bug at Ubuntu, or is this strictly advice for future > > bug submissions? > > It would be better next time unless you can test it on a FSF GCC source > release/SVN.
