I guess because he was profiling for IFU_MEM_STALL, not for wall-time.

NAK because
1. This is a gcc problem
2. Not everyone is using an intel x86-32 box which has such problems
3. IDE is in life-support mode and the relatives are already planning
the flowers.

Well. If the patch breaks anything we can dine on hats for a month. Seems
pretty inoffensive to me.

Yeah its a do nothing change that has no value. We can equally not apply
it and see no difference. Its make-work that might slow down some
systems.

Send it to the gcc people see if its a case they could/should optimise
