similar to: Passing llvm option -mem2reg to clang

I have used the following command for my pass (without -mem2reg): clang -Xclang -load -Xclang MYPASS.so -c ../../tests/test1.c For mem2reg, I tried the following: clang -mllvm -mem2reg -Xclang -load -Xclang MYPASS.so -c ../../tests/test1.c On Mon, Mar 21, 2016 at 9:26 PM, Mehdi Amini <mehdi.amini at apple.com> wrote: > >> On Mar 21, 2016, at 6:23 PM, Syed Rafiul Hussain

I have my own llvm pass which requires mem2reg. It worked fine with opt. However, I was trying to make it work with clang as I needed it to run some spec cpu benchmarks. Is there any way that I can mention mem2reg (PromotePass) pass as a pre-requisite in my own pass's implementation?

Unless mem2reg does something other than my understanding of it, I can't see why any pass would "require" that... It is not guaranteed to do anything to any particular piece of code, so relying on it seems very unreliable, I would think. -- Mats On 22 March 2016 at 04:32, Kevin Hu via llvm-dev <llvm-dev at lists.llvm.org> wrote: > Hi, > > > Is there any way that

Thank you all for your reply. if(a>10) b=10; else if (a<10) b = 5; Here is the IR of the if-elseif: 56 %0 = load i32, i32* %a, align 4 57 %cmp = icmp sgt i32 %0, 10 58 br i1 %cmp, label %if.then, label %if.else 60 if.then: ; preds = %entry 61 store i32 10, i32* %b, align 4 62 br label %if.end.4 63 64 if.else:

I have added -debug-pass=Structure, and found the following: ModulePass Manager X Analysis Unnamed pass: implement Pass::getPassName() FunctionPass Manager Module Verifier Bitcode Writer Pass Arguments: -x -y -z FunctionPass Manager X Analysis Y Construction Z Construction Even for getAnalysis<Y>(*F) and getAnalysis<Z>(&F), all the passes X,

Sorry, I should ask the following: finds all the instructions of a function where a particular variable is defined? Lets consider the following code snippet: 1. void foo(){ 2. int a, b; 3. if(a > 10) 4. b = 10; 5. if(a<10) 6. b = 5; 7. cout << b; 8. } I would like to know the instructions where variable b can be be defined, i.e, in this case, the instructions 4 and 6.

Hi, I am using llvm-3.8 for my project. Following is my getAnalysisUsage() method: virtual void getAnalysisUsage(AnalysisUsage &AU) const override { AU.setPreservesAll(); AU.addRequired<X>(); AU.addRequired<Y>(); AU.addRequired<Z>(); } Now, if I call getAnalysis<X>(*F), instead of invoking just the X pass, all the passes, i.e., X, Y and Z are being

Hi, I am wondering if anyone could run ArrayBoundChecks located in SafeCode-llvm37 (https://github.com/jtcriswell/safecode-llvm37) on llvm-3.8? Thanks. Syed -- Rafi

Hi, I am wondering if there is anything like def-use chain which finds all the instructions of a function where a particular value is defined? Thanks. -- Rafi

Dear helpers please provide me some helpful answer to my problem while I m trying to run a program .I m attaching both the program and the data to which I have to obtain my estimation results. "Motives.dat" is the data file, and "OBTfile4.3" is the complete code of program. by Running this // rawdata<-matrix(scan(inputFile, n = nsubj*ncomp), nsubj, ncomp, byrow = TRUE) \\

Dear Members i'm trying to access different packages used for Bayesian analysis, but failed to integrate after making the likelihood of the model the model like this a= exp(b)/summation(exp(b)) where 'b' = half of the natural log of 'a' please If some one knows about this type of integration for posterior distribution then pleae inform me SYED ADIL HUSSAIN MPHIL SCHOLER QAU,

Currently in the VM XML, I am passing the following command line argument as a passthrough argument: -netdev type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on -device virtio-net-pci,netdev=net1,mac=00:00:00:00:00:01,csum=off,gso=off,guest_tso4=off,guest_tso6=off,guest_ecn=off Is there another way to represent this in the XML file? maybe that may solve the problem.

Hello, I have a custom QEMU which requires some non-standard command line arguments to launch a VM. e.g., "--proc-type=secondary" option is always required to launch a QEMU VM. To launch the VM through libvirt (virsh) "How do I specify these non-standard options in XML? OR if thats not possible ,Can you guide me at which point (code file) libvirt converts the XML to QEMU command

There are a couple of problems with passthrough qemu: 1. virsh version/capabilities command executes "qemu -help" but this gives an error in my case because my customized qemu has to receive mandatory non-standard parameters "qemu -c -n -- -help". 2. Similarly when passing arguments as passthrough in a VMs XML. How can I make sure that these non-standard arguments are passed

Thanks Wangkai but libvirt infact pre-configures network tap devices and pre-opens /dev/vhost-net file and passes these to qemu as open, ready to use file descriptors. My issue is that my qemu requires that /dev/vhost-net directory is removed and it's kernel module be unloaded. Then it creates a vhost -net device using its own configuration.

​The qemu that I am using isn't modified at all. It's the VHOST drivers that are mounted elsewhere i.e., not on default /dev/vhost-net. Here is the command that I use to launch my qemu VM: qemu-system-x86_64 -cpu host -boot order=c -hda /root/Disks/ubuntu1.qcow2 -m 1024M -smp 2 --enable-kvm -name 'client 1' -nographic -vnc :2 -net none -no-reboot -mem-path /dev/hugepages

fileUrl <- "https://data.baltimorecity.gov/api/views/dz54-2aru/rows.csv?accessType=DOWNLOAD"download.file(fileUrl,destfile="./data/Cameras.csv",method="curl") I tried it after installing package "RCurl" but it give error message: Error in download.file(fileUrl, destfile = "Cameras.csv") : unsupported URL schemeI can you help me to solve this

I am using a custom qemu to launch a vhost enabled VM. The qemu doesn't use the default "/dev/vhost-net" directory as character device. Due to this I am getting the error: qemu-system-x86_64: -netdev type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on: vhost-net requested but could not be initialized ​Is there a way to tell libvirt to ​avoid using the default

Hi, I want to add "mem2reg" pass similar to this: PassManager PM; PM.add(new LoopInfo()); PM.add(new Mem2Reg()); // What's the class name for this pass I couldn't find the name of corresponding class and header file of mem2reg pass except "mem2reg.cpp". So how can I add mem2reg pass into my pass manager? Thanks, Riyad -------------- next part -------------- An
