Adding data.frames together
...t is not what I want. In my finally solution, I need to do this with multiple data.frames that slot-wise are identical, but each slot length is different between data frames. Seems like there should be an easy solution, but I just have not stumbled across it in the documentation. Thanks, John C. Sweval Database Architect Illumigen Biosciences, Inc.

libvirt and guest processes
Hi I wanted to find out if there is way to list all the running processes in a guest VM from the hypervisor. Like the output of 'ps -ef' from inside the guest VM, but without logging in or ssh into it. Thanks dtsweval

[LLVMdev] Python to VHDL using LLVM; was "Re: LLVMdev Digest, Vol 123, Issue 3"
The only VHDL to LLVM project that I know of is nvc. [0] I haven't tried it personally and from a cursory look through the source it seems like there is a LLVM backend and a "native" backend (not sure what that means). If you're really crazy you might want to see if you could massage GHDL [1] (VHDL GCC frontend) + DragonEgg [2] (LLVM backend for GCC) to get you LLVM IR. I'm

64-bit Windows 2003 build of R
...no longer "current" with C builds, i.e. - I haven't done one in years and have never used the Intel 64-bit compiler. I could use any suggestions, make file, assistance, etc. from anyone who may have already compiled a 64-bit Windows version of R. Thank you for any assistance, John C.

[LLVMdev] decompiler
Hi - Not sure if anyone else saw this or cares about a decompiler (not personally tested) https://github.com/draperlaboratory/fracture I wonder if they have been in contact with anyone in the community in getting this upstreamed. Does it look interesting to anyone else? (thoughts/random comments/feedback)

Re: libvirt and guest processes
As I know, you can use Libvmi API to access the memory of VM and then walk through the double-linked list of process to reconstruct the process list. it is easy, and libvmi has provide the example 在2015-04-20 22:52:02,hanyandong<hanyandong@iie.ac.cn>写道: > On 20.04.2015 06:22, dt sweval wrote: > > Hi > > I wanted to find out if there is way to list all the running processes in a > > guest VM from the hypervisor.

[LLVMdev] How to extract the starting address of each basic block with llvm?
Dear all, I use the clang frontend to produce the control flow graph of a C program through this command: clang -Xclang -analyze -Xclang -analyzer-checker=debug.DumpCFG test.c The produced information contains all the basic blocks identified by labels, e.g. B1, B2, etc. along with their predecessors and successors. Is there a way to get the starting address of each of these basic block? I would

[LLVMdev] Proposal: function prefix data
Hi, I would like to propose that we introduce a mechanism in IR to allow arbitrary data to be stashed before a function body. The purpose of this would be to allow additional data about a function to be looked up via a function pointer. Two use cases come to mind: 1) We'd like to be able to use UBSan to check that the type of the function pointer of an indirect function call matches the
