Hi, I have been trying to find out CPU topology using libvirt. I understand that I can find out the number of cores/sockets/ threads etc through getCapabilities() function. What I am wondering is that is there any function that can provide me the exact topology like how many sockets, how many sockets per core and number of threads per core, if applicable or may be info about numa cells.  Is there

> I'm not following your example.  If you have two sibling loops with the same parent, one will frequently, but not always dominate the other.  Can you give a specific example of when forming a recurrence between two siblings (without one dominating the other), is useful? The situation can happen with guarded loops or with a user guard like below: if...

...s}{s, s}(or, {x, y}, {z, w}) I have an instruction that can access the 2nd and/or 4th scalar and an instruction that can access the 1st and/or 3rd scalar. What I need to do is that given the first scalar, I need to be able to select the 2nd scalar, or/and given the 3rd, select the 4th. I define a sibling register as a register that has the same parent and a cousin as a register that has the same grandparent. So 'x' is a cousin of 'w' because of the grandparent class and 'x' is a sibling of 'y' because of the parent class. I know I can move to parent/children regi...

...on would return those values and when), but returning nullptr from getAddExpr or getSCEVAtScope may be problematic since they currently return valid pointers all the time and changing that would be error prone and would increase code complexity. Returning SCEV_Unknown from getAddExpr would seem plausible except that it would not allow for expression simplifications where recurrences over non-dominating loops can get canceled out. Having said that it may still be a reasonable middle-ground solution. Philip, do you have any thoughts on that? Bardia Mahjour From: Jimmy Zhongduo Lin <jimmy.zh...

...bers have changed. There are also now a few more basic blocks very small basic blocks in the function, and therefore there are some slight differences. I tried to go back to earlier commits, without success for some reason... This is however very similar, except that there becomes two COPYs back to sibling value after the loop. My apologies [vregs 76->111, 87->122]. 1. The interval for %vreg111 first covers nearly the entire function. Then it gets split into two intervals, where one covers the inner loops, which makes sense. selectOrSplit %vreg111 [68r,400B:1)[400B,688r:6)[688r,752B:4)[752B...
