And of course if the volatile variable in the 3506 example code was an MMIO register, there would not be any atomicity, at least not given the hardware I have come across. And I am not aware of any devices where it would be useful to blindly increment an MMIO register. So I believe that this is a non-issue. Or am I missing something? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33102
