How to avoid sort of x values in dotplot?
I am trying to avoid that dotplot sorts my x-values. They are in the correct order in the data.frame and the connections between the x-y values follows this order, but the placement of the x-values on the x-axis is re-ordered. In the following example, the order should be "d1", "d8" and "d15". However, this script places "d8" at the highest x position. Any

nested for loops
Dear Admin, I will appreciate if you advise me an effective way to write the following R code including nested for loops. I cannot do it by using expand.grid function because it results with memory allocation problems. Thanks for your time and consideration. for(d1 in 0:n){ for(d2 in 0:n){ for(d3 in 0:n){ for(d4 in 0:n){ for(d5 in 0:n){ for(d6 in 0:n){ for(d7 in 0:n){ for(d8 in 0:n){ for(d9 in

[LLVMdev] [3.7.0] Two late issues with cross compilation to mips
Thanks. This is making a lot more sense now and it's looking like this issue isn't Mips specific. Here's the IR dump before simple register coalescing (note: I've patched the IR printer to print the contents of the regmask): 4480B %vreg260<def> = LDC1 %vreg253, <cp#3>[TF=6]; mem:LD8[ConstantPool] AFGR64:%vreg260 GPR32:%vreg253 4496B %vreg261<def> = FMUL_D32

Extending RAIDZ.
Yeah:) I''d like to work on this. Here are my first observations: - We need to call vdev_op_asize method with additonal ''offset'' argument, - We need to move data to new disk starting from the very begining, so we can''t reuse scrub/resilver code which does tree-walk through the data. Below you can see how I imagine to extend RAIDZ. Here is the legend:

[LLVMdev] Pointer vs. integer: backend troubles
Hi everyone, I am currently working on a backend for the TriCore architecture. Unfortunately, I have hit an issue with LLVM's internal representation that's giving me a bit of a headache. The problem is that LLVM assumes that a pointer is equivalent to a machine-word sized integer. This implies that all pointer arithmetic takes place in the CPU's general-purpose registers and is done

Hi Jan, Attached patch dumps io page fault flags. The flags show the reason of the fault and tell us if this is an unmapped interrupt fault or a DMA fault.
