[LLVMdev] Python version requirement for LLVM
...//llvm.org/docs/GettingStarted.html currently mentions Python 2.5 as a minimum required version. I'd like to use argparse <https://docs.python.org/dev/library/argparse.html> in a script and be able to test this script. This requires Python 2.7. This version has been around since 2010, and afaiu, is available on all modern platforms. Is there any reason not to change minimum required version of Python to 2.7? -- Regards, Alexander Kornienko -------------- next part -------------- An HTML attachment was scrubbed...

RLIMIT_MEMLOCK in container environment
...ed to the pod, needed by libvirtd and other services. One of the capabilities libvirtd requires for successful startup inside a pod is SYS_RESOURCE. This capability is used to adjust RLIMIT_MEMLOCK ulimit value depending on devices attached to the managed guest, both on startup and during hotplug. AFAIU the need to lock the memory is to avoid pages being pushed out from RAM into swap. In KubeVirt world, several libvirtd assumptions do not apply: 1. In Kubernetes environments, swap is usually disabled. (e.g. kubeadm official deployment tool won't even initialize a cluster until you disable it...

[LLVMdev] debugging LLVM-JITted code
...that faithfully describes the JITted code into memory along with the JITted code itself and point the debugger to it. Let's assume that the bridge with the debugger is taken care of (e.g. http://llvm.org/docs/DebuggingJITedCode.html) - my concern in this question is solely with the LLVM side. AFAIU, LLVM currently includes very partial support for emitting DWARF info with JIT, in the JITDwarfEmitter class. What it has is just a way to emit stack frame information (symbols and DWARF CFA), to allow meaningful core dumps from JITted code, with stack information. This is useful, but obviously ver...

Memory fragmentation and PCI passthrough
...irmware (few allocs, each bellow 100k). DomU kernel cmdline: console=hvc0 iommu=soft earlyprintk=xen There is two cases (I think): 1. With IOMMU 2. Without IOMMU I''ve tried only the second one. Is there any known solution for this problem? Some ideas: 1. With IOMMU pass iommu=pv to Xen. AFAIU domU will not need iommu=soft parameter then, right? Will it work then with fragmented memory? 2. Force somehow on xen/libxl to allocate memory (for domU) in chunks of, say 4MB, to not fragment it so badly. Is it doable? In tmem documentation is also described some workaround for this: reserve so...

[LLVMdev] Fixed register operations
...le to define an instruction as always having a certain register as operand in XXXInstrInfo.td? I know I can do it defining a single-register register class, but I need that register also to be on a broader class for other operations (and it is not possible for a reg to be in several classes AFAIU). Thanks! Carlos

[LLVMdev] Pass Incompatibility
...ractor::ExtractCodeRegion(const std::vector<llvm::BasicBlock*, std::allocator<llvm::BasicBlock*> >&): Assertion `BlocksToExtract.count(*PI) && "No blocks in this region may have entries from outside the region" " except for the first block!"' failed. AFAIU, this assertion is not related to ordering of analysis passes. Analyzing incoming bb vector for ExtractCodeRegion() may help you understand why you're triggering this assertion. May the vector is stale ? - Devang

Using MASSv3's example from 8.7 in R?
Dear list! I am interested in learning about MLE and I wonder whether it is possible to use the examples for maximum likelihood estimation given in 8.7 in MASSv3 with R? AFAIU R does not have a direct replacement for S-PLUS's ms() which the examples use for the fitting, but optim() may be of help for me. However, I am not sure how I can convert the use of ms() using optim()--is there an explanation how to do this somewhere? Thanks. Best wishes, Sven C. Koehler =...

Reset R's library to base packages only (remove all installed contributed packages)
...omfortably "reset" R's library such that it only contains only the base packages again? In other words, how can I uninstall all contributed packages that I installed? Is there some sort of index that's keeping track of what has been installed? If so, a pointer would be great. AFAIU, if you don't create such an "index file" yourself and loose track of what you installed, probably the best way to "reset" R is to actually re-install it. That's exactly what I'm trying to avoid. I would like something like path.lib <- "path/to/R/lib&quot...

Newbie X100P question
...posed to be a FXO card, but there are 2 rj-11 plug on the card. One is labelled "phone" and the other "pstn". When i plug the "pstn" on the wall and the "phone" on my analog phone, everything (incoming and outgoing calls) works like before (without asterisk). AFAIU, i should have an FXS card in my box to be able to use my analog phone, so why does it work this way ? Second question, what is the cheapest card to use one analog phone only (TDM400 is too expensive). I read there's a S100U which seems to be a single FXS card, but I can't find a webshop s...

Feature request: 'file.path()' accepting an input vector
Dear list, I have a small feature request regarding the implementation of 'file.path()': It'd be great if 'file.path()' would allow to specify an input *vector* instead of solely rely on a specification via the three dot argument. AFAIU, currently it's only possible to "manually" specify each path component via the three dot argument: > file.path(letters[1], letters[2], letters[3]) [1] "a/b/c" Providing a vector object will result in the same vector being returned, instead of a slash separated scalar...

R CMD check --as-cran: sslv3 alert handshake failure
...orted both by the win-builder and the rhub services: * R 3.3.2: https://win-builder.r-project.org/xj8fwadE4K31/00check.log * R devel: https://win-builder.r-project.org/xj8fwadE4K31/00check.log * R 3.2.5: https://builder.r-hub.io/status/R.devices_2.14.0-9000.tar.gz-a252b2d919124c63bc976d78befce161 AFAIU, this is due to the HTTPS webserver not having SSL3 disabled, e.g. http://unix.stackexchange.com/questions/192944/how-to-fix-curl-sslv3-alert-handshake-failure. Is this something that should be fixed in R CMD check --as-cran itself? The only workaround I can see as a package maintainer is to drop...
