Dear all, I am installing the libvirt 1.2.5 on my newly installed Fedora19. When I run ./configure, an error is reported: "You must install the libyajl library & headers to compile libvirt" In fact, the package yajl-2.0.4-2fc19.x86_64.rpm has been installed on the fedora19. I found several links talking about this error and I downloaded 3 files (configure.ac, m4/virt-yajl.m4,

Hi all, I'd recommend Andy Trick be made code owner of "instruction scheduling" (including MI, pre-RA, and post-RA schedulers). I am also recommending Nadav Rotem be made code owner of "loop vectorizer". Evan

Thanks Quentin. I'm trying to examine from the operands of the return instruction, and then to get the last assignment of those. I thought use_iterator/reg_iterator may suit better than just loop through the machine basicblock in the reverse order.

Can you see the USB device in the lxc? My answering assumes you cannot see the USB device in the container. If you can see it, please ignore my answer. According to my understanding, “hostdev mode='subsystem' “ is used with KVM only. We use this if we want to passthrough a device to a KVM virtual machine. After doing that, the host machine will lose control of the device. If container is

Dear all, I am not clear about the 'vcpu' element for CPU allocation. I allocated 1 vCPU to my container, after I started the container, I ran 4 computation-intensive tasks on the container. And I found all the 4 physical core are 100% used (my host has 4 physical cores and no other application ran on the host except the container). That is, all available cores were used by the container.

Hi all, I'm trying to write a custom module-level pass that runs before AsmPrinter::EmitStartOfAsmFile(), since I'd like to have some processed information available once entering this function. Looking through "Writing an LLVM pass" documentation, it's not clear to me if this is possible. I've also tried putting the pass in different orders (addPreISel, addIRPasses,

Dear Fil, I am not sure if my answer can help you. I had ever asked a similar question to Daniel and I was using a thirty-party card. As a container uses a shared kernel with the host, so hostdev mode='subsystem' doesn't make sense. Maybe you can try to use hostdev mode='capabilities'. Please see http://libvirt.org/formatdomain.html#elementsHostDevCaps Hope this helps Cheng

I'd also like to point out that, when setting up a linux container with _just_ the lxc tools available in ubuntu, all that was needed to be done was whitelist the appropriate cgroups for the Android devices. The lxc tools seem to create the appropriate character devices when you detach/attach the Android device via USB, and the Android `adb` tool recognized the devices. So, a tangential

Thanks. This is going in the right direction IMHO. Obviously, please make sure you add comments to the data structure and convert all the targets first. Also, please don't forget to send an email to llvmdev to warn owners of all the out-of-tree targets about the ABI change.

Hi folks, I would like to find out the machine instructions that use some given registers in the reverse order, and I came across these iterators (use_iterator/reg_iterator). However, there are two things I noticed: 1) These iterators seem to traverse the machine function a bit differently from what I get from the machine function dump. In other words, the use_iterator list is not constructed in

When multiple GEPs or other operations are used for the address calculation, OptimizeMemoryInst() performs address matching and determines a final addressing expression as a simple form (e.g., ptrtoint/add/inttoptr) and sinks it into user's block so that ISel could have better chance to fold address computation into LDRs and STRs. However, OptimizeMemoryInst() seems to do this transformation

Hi guys, I’m trying to figure out a way to assign initial values to function arguments. For a function in IR: define i32 @main (i32 %0, i32 %1) { %tmp = add i32 %0, %1 ... } I would like to make sure %0 has some initial value (e.g. i32 0) under some circumstances. Is there any easy way to do this? I understand that %0 comes from a live-in value which is defined from outside of the function. I

Dear Evan Chang: I register incorrect Register class for MVT::f64. I have fixed it. Thanks your advice. "-view-legalize-dags" is very good option. But I don't know why my LLC do not know " -view-legalize-type-dags" option. By the way, I use llvm 2.5 merged from llvm2.4.
