similar to: [GSoC 2017] Clang-based diff tool project

My original idea was to write a semantic diff tool that just does some simple things up front: create an MD5 from all top level blocks of the code. Start by just finding matching blocks of code ('{' and '}', '(' and ')') and remember the source locations for these and their MD5 values. Run a normal diff on the code and see what blocks the diffs fall into. Then try

I am currently considering the gumtree algorithm which is described in [1]. It is able to detect code moves, updates. There is also a java implementation of gumtree. It supports C++ via srcML, however this seems to be quite incomplete and buggy. The algorithm consists of a top down and a bottom up traversal of the AST that result in a matching of corresponding nodes. It contains some heuristics

Hi, I am writing a plugin to get information about the OpenMP constructs from the AST. I am basically writing a “RecursiveASTVisitor” and I am trying to find the OpenMP statement and get information like filename and line of code. When I am visiting recursively each statement I have my own switch on the “StmtClass” and for now I am focusing on “OMPParallelForDirectiveClass”. In my understanding,

Hello Guys,I am developing a plugin of clang and hope it can convert some C++ functions to C++/CX wrapper classes for WinRT system. If so, it would do a lot of work automatically.Now I have been somewhere. Using clang libraries, I could fetch the elements of C++ code for example, return type, function name, parameter list and others. Should I inherit "clang::Decl" to express C++/CX

I wrote a plugin using ASTConsumer and RecursiveASTVisitor to find "interesting" variables and functions. I'm wonder if there is a way to save/flag/metadata these so later on at the IR level I can use this information in a Pass. As far as I can tell nothing currently would allow me todo this and I'm wondering what exactly it would take to do something like this. After stairing

Hi, Isn't clang::CodeGenOptions::EmitDeclMetadata what you need?

Hi. I've tried to search the way to write a pass for clang like a pass for opt, but I haven't find it. Is it possible? I need to save class inheritance of the program being processed to external file. Thanks! Yours sincerely, Kadysev Mikhail -------------- next part -------------- An HTML attachment was scrubbed...

Some terminals support CSI u style encoding of keystrokes, typically via the Kitty keyboard protocol[1]. Program wishing to receive this encoding need to send a sequence like "CSI > 5 u" to enable it. Imagine a process tree like xterm -> bash -> ssh -> foo where foo is any program that enables CSI u mode (such as a newfangled shell or text editor). If the network

L.S., I'm currently in the process of creating Debian packages for clang/llvm release 3.9.0. For this I'm using the steps as explained on 'http://apt.llvm.org/building-pkgs.php'. Up until now I have done: $ debcheckout svn://anonscm.debian.org/svn/pkg-llvm/llvm-toolchain/ $ cd llvm-toolchain/branches $ sh 3.9/debian/orig-tar.sh RELEASE_390 final Now, as is explained, I would

Hi, I am trying to use LLVM to generate C (partly, Intel AVX) code to test some abstractions. Apparently, most of the documentation is related to generating LLVM-IR. Are there any tools to do this? (I have generated AST from these abstractions. I want to generate C code from it). Thank you! :) PS: If this is a wrong mailinglist, help me with the right one. -- Regards, *Aditya Atluri,* *USA.*

LLVM Weekly - #1, Jan 6th 2014 ============================== Welcome to the inaugural issue of LLVM Weekly, a weekly newsletter (published every Monday) covering developments in LLVM, Clang, and related projects. I've been a long time lurker on the LLVM and Clang mailing lists and have been using LLVM extensively in my PhD research for the past 4 years. I thought it might be worthwhile to

Hi all, Given a couple of lines of C++ code `int x = 42; int y = x`, we end up with the following LLVM IR instructions: %x = alloca i32, align 4 %y = alloca i32, align 4 store i32 42, i32* %x, align 4 %0 = load i32, i32* %x, align 4 store i32 %0, i32* %y, align 4 Is it possible to instrument the IR to perform a value trace? What I'd like to do is stream a log of memory copies (reads then

I am interested in putting together a tool which can verify that an external declaration conforms with the actual definition. A.c: extern int32_t foo(); Int bar() { return foo(); } B.c: int64_t foo() { ... } I had thought that I could use the debug information but the debug information in A.o does not include the type of the declaration "foo", just the type of bar. Is there a way to

Hi, I know most compilers go from AST to CFG. I am writing a decompiler, so I was wondering if anyone knew of any documents describing how best to get from CFG to AST. The decompiler project is open source. https://github.com/jcdutton/libbeauty The decompiler already contains a disassembler and a virtual machine resulting in an annotated CFG. It uses information gained from using a virtual

Dear R-list, Is there a way to convert the typical long R data-format to a 1-line per subject format?
