similar to: LLVM-based Mutation Testing, first results.

Hello All, Started out awhile ago trying to select columns in a dataframe whose names contain some variation of the word "mutant" using code like: names(KRASyn)[grep("muta", names(KRASyn))] The idea then would be to add together the various columns using code like: KRASyn$Mutant_comb <- rowSums(KRASyn[grep("muta", names(KRASyn))]) What I discovered though, is

Hello Everyone, I have what I think is a complex text parsing task. I've provided some sample data below. There's a relatively simple version of the coding that needs to be done and a more complex version. If someone could help me out with either version, I'd greatly appreciate it. Here are my sample data. haveData <- structure(list(profile_key = structure(c(1L, 1L, 2L, 2L, 2L,

Hello Alex, This is an interesting approach! Thank you for that! I understand the basic idea but sadly... My skills in handling the IR are not very high, so I can't imagine where and when to replace the calls to b() with the trampoline. The only thing I can handle would be creating that trampoline variable. Also will this approach be a problem for really time critical tasks? Since I replace

Hello everyone, Are there any reasons the unittests in LLVM repo are split into independent executables, e.g. ADTTests, AnalysisTests, etc. Are there any performance or easy-to-use reasons for this? I plan to migrate to GTest from a project where we have all unittests in a single executable. - Paweł -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, Apologies if this is the wrong list, I am a first-time poster here. I have an experiment in which an output is measured in response to 42 different categories. I am only interested which of the categories is significantly different from a reference category. Here is the summary of the results: summary(simple.fit) Call: lm(formula = as.numeric(as.vector(TNFa)) ~ Mutant.ID, data =

Hello All, This will probably be easy for some but isn't for me. Currently am working on a text mining exercise. Want to be able to predict whether cancer patients got KRAS testing, and, if so, whether the test yielded a result of wild type/negative or mutant/positive. I've begun with a "bag-of-words approach" that looks at the count of specific terms in the medical records and

Hi everybody, I do write some Clang/LLVM related articles on my blog[1][2], and I will be happy to write for LLVM’s blog. However, I can’t omit bike-shedding :) Forgive me my directness, but current blog doesn’t look like something close to 2016. The blog already has lots of great articles. But it’s so hard to grasp valuable information when you have to read non-highlighted C++ code. I think I

Hi there, I have a question regarding this documentation page: http://llvm.org/docs/Projects.html IIRC LLVM has moved away from Makefile's and uses CMake only. The question is: Is the page outdated or is it a recommended way for creating LLVM based project? P.S. I’m trying to create a project using CMake, though I’m seeing some issues (didn’t manage to include headers so far). --

Hello - does anyone know whether there are any packages for Mann-Kendall mutation tests in R available? The only one I could find online is this MK_mut_test: Mann-Kendall mutation test in Sibada/sibadaR: Sibada's accumulated R scripts for next probably use to avoid reinventing the wheel. (rdrr.io) <https://rdrr.io/github/Sibada/sibadaR/man/MK_mut_test.html> but there doesn't seem to

Hi there, I’m curious is there any (official or not) communication channel for upcoming EuroLLVM? If there is none besides mailing lists and IRC, shall we then setup something like Slack? -- AlexDenisov Software Engineer, https://lowlevelbits.org

Hi everyone, I’m working with the LLVM C API now. I see that several functions are deprecated, however the only notion is in comments around the function. Is there any specific reason why __attribute__((deprecated)) is omitted? Will it make sense to send a patch with such additions? -- AlexDenisov Software Engineer, http://lowlevelbits.org -------------- next part -------------- A non-text

Hello everyone, I observe a weird behavior switching from clang-4 to clang-5 (and any higher version). I compile an executable that depends on LLVM. Everything works fine with clang-4, but when I run the executable compiled with clang-5 I see the following error: : CommandLine Error: Option 'rewrite-map-file' registered more than once! LLVM ERROR: inconsistency in registered CommandLine

Hi everyone, I run some functions using ORC JIT, now I need to add custom instrumentation. I want to add two callbacks to each function: ‘enterFunction' at the beginning and ‘leaveFunction' at the end. Intuition says that I could ‘just' insert CallInst's to the first and the last basic blocks in the function. Am I correct? Are there any other/better way to do this? Is there

r247321 refactors the code so that it should build on Mac. I haven't actually tested it on Mac -- so please help me and send follow up patches if needed. check-fuzzer will still fail because some of the libFuzzer tests require dfsan. I'd use some help from someone with a Mac to modify lib/Fuzzer/test/CMakeLists.txt so that it does not run dfsan-dependent tests on Mac. Thanks, --kcc On

Thanks for the hint, I didn’t know about this option. That’s a great reference! However, I am trying to be a compiler/language agnostic. Also (for whatever reasons) I need a numeric ID of a function rather then its address. So the question is still opened. May I assume that the following always holds: The first basic block in a function is an entry point and the last basic block in a function is

Hi devs, hi Lang, I use ORC’s SimpleCompiler to compile modules into object files and it works just great, however I’m having an issue: a module gets changed a bit when I compile it (some transformations/optimizations applied). I tried to set optimization level of a TargetMachine to None, but the module gets changed anyway. The question is: how can I prevent a module from being modified during

Hi there. I’m trying to use LibFuzzer on OSX and face some issues: I checked out LibFuzzer documentation[1] and managed to proceed until the final step of the first example. Now I see linker errors related to dfsan, dfsan’s documentation[2] states explicitly “DataFlowSanitizer is a work in progress, currently under development for x86_64 Linux.”. Does it mean that LibFuzzer available only on

Hello everyone, My name is Alex, I'm hobbyist compiler hacker who lives in Berlin, Germany now. I'm thinking about organising "LLVM Social" meetups in Berlin, however I don't really know how many people are here, and how many of them are interested in getting in touch. If you want to participate or have any questions - feel free to answer to this thread, or to send me a

Hi, I am looking for genetic optimization package that allow to define my own chromosome solution and crossover/mutation opoerations. I checked genoud and genopt, not with much effort of 'cause, with no luck. Any one can shed some light on this? thanks.
