Hey everyone! This Summer we managed to make the Clang Static Analyzer support the LLVM and LLVM-based projects with my mentors Artem Dergachev and Gabor Horvath. For a more detailed documentation please visit my final report: https://docs.google.com/document/d/1o9-xEWbzivUGKIOXp9jUNZYq0mkecd5KH5dBN5Hdlu8/ The project in a nutshell: I have fixed the most annoying false positives and added

Sylvestre Ledru looks after the scan-build web report, but I understand it hit a few issues back in June (it normally updates a few times a week). We also discussed whether there was an automated way for those updates to email the summary to the cfe/llvm dev lists, indicating total warnings, and highlighting any new ones (we punted that discussion until the GSoC was done - btw thank you

+Aaron because i think he uses scan-build on Windows more or less successfully. I won't have time for setting up a Windows machine for myself in the nearest future. Could you tell us exactly what you're doing and what exactly does it print to console, more in the spirit of http://www.catb.org/~esr/faqs/smart-questions.html ? > scan-build: Not supported for windows.

In various debug dumps (eg., Clang's -ast-dump), various objects (eg., Stmts and Decls in that -ast-dump) are identified by pointers. It's very reliable in the sense that no two objects would ever have the same pointer at the same time, but it's unpleasant that pointers change across runs. Having deterministic identifiers instead of pointers would aid debugging: imagine a

Hey, I am Swapnil Raj I am student in Trinity College Dublin and I am interested in working on LLVM. I am really interested in two projects listed, the first one is the extending the clang AST with template information and the second is finding smart null pointer dereferences. I am passionate about compilers and interpreters, I have written a few small language based on lambda calculus. I am

In 2.4.0 (and SVN) I am seeing xyplot creating empty pages for high page counts in layout - contrary to the manual which says high page counts should not matter. Everything works fine in 2.3.1. library("lattice") A<-data.frame(x=1:10, y=sin(1:10), z=round(1:10/3)) xyplot(x~y|z, A, layout=c(1,1,10)) The snippet above produces a valid plot in R 2.3.1, while in 2.4.0 and later I see

Thanks for the detailed explanation. So is changing the analysis technique from path sensitive (symbolic execution) analysis to some other technique bring in the soundness property ?

This is a great idea! I personally also wouldn't mind going further in debug builds and actually create and store sequential IDs with the objects and take the small memory hit for improved debuggability. The `PersistentId` field in SelectionDAG works that way and has helped make the output more readable IMO. - Matthias > On Aug 28, 2018, at 5:22 PM, George Karpenkov via llvm-dev

Hi all, I am working with some large data sets (1-4 GB) and have some questions that I hope someone can help me with: 1. Is there a way to turn off garbage collector from within C interface ? what I am trying to do is suck data from mysql (using my own C functions) and I see that allocating each column (with about 1-4 million items) takes between 0.5 and 1 seconds. My

Hi How do I specify an S4 class with a slot that is potentially numeric, but NA by default? I want the slot to be NA until I calculate its value (an expensive operation, not needed for all applications). When its value is known, I will create a new object with the correct value inserted in the slot. I want "NA" to signify "not known". My attempt fails because

Hi all, I was looking at the data frame subscription operator (attached in the end of this e-mail) and got puzzled by the following line: class(x) <- attr(x, "row.names") <- NULL This appears to set the class and row.names attributes of the incoming data frame to NULL. So far I was not able to figure out why this is necessary - could anyone help ? The reason I am

Excuse my ignorance (I'm not great with Git) but how would it differ for workflows of people who use a Git repository for local work but still use `svn up + patch + svn commit <list of files>` to actually land post CR or for NFC patches, while resolving conflicts during a pull into a local (non-trunk) branch manually, after the eventual full switch to GitHub? I'm aware that SVN

Hi All, My problem is about parallel execution of R-scripts. My platform is linux. A program that is written in C needs to execute multiple R-scripts simultaneously. The C program makes use of multi-threading. Each thread must initiate the execution of one script. Performance is very important. Appearantly the R C-API does not provide a mechanism for parallel execution.. It is preferred
