Hi experts, When I test lxc container with lxc-enter-namespace command, It reported an error as following: root@debian:~/github/libvirt# vir lxc-enter-namespace lxc --noseclabel /bin/df -hl error: Cannot get namespaces for 3145: Function not implemented It seems that setns is not supported by my kernel. But from the following info, It seemed the reason is just libvirt/autoconf doesn't recgonise setns. root@debian:~/github/libvirt# grep setns /proc/kallsyms ffffffff8105b78b T SyS_setns ffffffff8105b78b T sys_setns root@debian:~/github/libvirt# ./configure | grep...

Hi Gaofeng, It seems that I've got the answer. In manual page about setns, it said that library support was added to glibc in version 2.14 while my libc version is 2.13. Thanks for help anyway.

Hi, I am having some issues with how some of the instructions are being legalized. So this is my intial basic block. The area of concern is the last three instructions. I will pick and choose debug output to keep this small. SelectionDAG has 36 nodes: t0: ch = EntryToken t6: i32,ch = CopyFromReg t0, Register:i32 %vreg507 t2: i32,ch = CopyFromReg t0, Register:i32 %vreg17

what's the semantics for setCC if one of the operands is NULL pointer? %ptr=alloc int seteq int*, %pt, NULL what's the result for the second instruction? How about setne, setlt, setgt, setle, and setge? Thanks! Jianzhong

But isn't kinda silly that we transform to xor and then we transform it back. What is the advantage in doing so? Also, since we do that method, I now have to introduce setcc patterns for i1 values, instead of being able to just use logical pattern operators like not. -Dilan On Fri, Jul 21, 2017 at 11:00 AM Dilan Manatunga <manatunga at gmail.com> wrote: > For some reason I

Note: Question is written after describing what I have coded. Hello LLVMDevs, I am trying to impliment floating point comparsion for an architecture which supports following type of floating point comparision if FPU is available: fcmp.un --> true if one of the operand is NaN fcmp.lt --> ordered less than, if any input NaN then return false fcmp.eq --> ordered equal, if any input NaN
