QingShan Zhang c2b6c547dc [PowerPC] Add Itineraries of IIC_IntRotateDI for P7/P8 
When doing some instruction scheduling work, we noticed some missing itineraries.
Before we switch to machine scheduler, those missing itineraries might not have impact to actually scheduling, 
because we can still get same latency due to default values.

With machine scheduler, however, itineraries will have impact to scheduling.
eg: NumMicroOps will default to be 0 if there is NO itineraries for specific instruction class.
And most of the instruction class with itineraries will have NumMicroOps default to 1.

This will has impact on the count of RetiredMOps, affects the Pending/Available Queue, 
then causing different scheduling or suboptimal scheduling further.

libcxx Last week, someone noted that a couple of the time_point member functions were not constexpr. I looked, and they were right. They were made constexpr in p0505, so I looked at all the other bits in that paper to make sure that I didn't miss anything else. There were a couple methods in the synopsis that should have been marked constexpr, but the code was correct. 2018-08-29 23:02:15 +00:00
