[LLVMdev] Post-dominance analysis for multiple-exit functions
...I'm implementing Pingali & Bilardi's optimal control
dependence algorithms: http://doi.acm.org/10.1145/256167.256217.)
Consider, for example, a simple function with a single branch and two
exits:
define i32 @f(i32 %X) {
entry:
%0 = icmp eq i32 %X, 0
br i1 %0, label %exit1, label %exit2
exit1:
ret i32 1
exit2:
ret i32 0
}
The existing PostDominatorTree analysis will produce a forest of two
trees, each containing one node (exit1 and exit2, respectively).
Critically, entry will not be present in either of these trees,
because it is not post-domin...

sysctl_out_proc() race in stable w/ patch
...e results to user memory. If it stalls during the copyout (e.g. the
user memory has to take a vm_fault) and the process is ripped out from
under it it will go looping into never never land.
The solution is very simple, simply PHOLD()/PRELE() the process during
the copyout() and in exit1() wait for the lock count to go to 0.
The patch below is a hack and cannot be directly applied due to other
changes in my tree, but if someone would like to tackle this for
4.x I've provided you with a good start.
The problem doesn't appear to be an issue in -current with...

"sleeping without queue" ?
Hello!
My attempt to build openoffice.org-3 seems to be hanging. Pressing
Ctrl-T produces:
load: 0.11 cmd: tcsh 79759 [sleeping without queue] 0.00u 0.00s 0% 0k
(tcsh is used by OOo's build-script). What is this "sleeping without
queue" state, and why is process in it for so long?
This is an 4-CPU amd64 system with 4Gb of RAM. Only 16% of the swap is
currently in use and
