...ame would hold for the gold plugin... LLVM/clang's involvement is mostly just to do the instrumentation, which is a pretty well-isolated task. The allocation site metadata I just mentioned is probably the only change-prone thing. Of course, there is a problem of breakage/churn in the libcrunch/liballocs stuff... in particular, things like new DWARF features can break things. I have no good answer to that, except that more hands make light(er) work. > How will the feature be tested? On that, I have no idea, and I'd have to take your lead on that. To make an analogy with another out-of-tr...

...hack to propagate certain type info (in uses of "sizeof") onwards to LLVM so it can be used in a data-flow analysis. - Hints from the programmer: these are necessary to declare allocation functions, besides standard ones (malloc etc.). This is currently done with an environment variable (LIBALLOCS_ALLOC_FNS) though I've thought of adding a command-line option too. These declarations have effect at both compile and link time. - Compiler wrapper and helper tools: currently a mixture of shell, Python and C++ helpers building on a pile of my own libraries (libdwarfpp, dwarfidl, liballocsto...

Dear Michael, The symbols that are said undefined by the compiler live in libAllocator.a. That file should be in Release/lib/, do you have it? It is possible that the compiler has linking order problems. What is the version of your gcc? You can try changing the link order of the make command by editing tools/vmkit/Makefile. Also, you should know that the GC of vmkit does...

Hi, I can't seem to get VMKit to compile correctly. I'm on a 64 bit Jaunty system. I compiled llvm and llvm-gcc from the subversion source no problem, but when I try to compile VMKit I get some issue with GCAllocator: /home/mmwu/Download/llvm$ ./configure /home/mmwu/Download/llvm$ make ENABLE_OPTIMIZED=1 /home/mmwu/Download/llvm$ make ENABLE_OPTIMIZED=1 install ...

Hi everyone, At EuroLLVM, Chandler and I chatted about the design for a potential TBAA sanitizer. Here's my attempt to summarize: C/C++ have type-based aliasing rules, and LLVM's optimizer can exploit these given TBAA metadata added by Clang. Roughly, a pointer of given type cannot be used to access an object of a different type (with, of course, certain exceptions). Unfortunately,

Also available here: https://github.com/rwmjones/nbdkit/tree/2020-windows-mingw This is the port to Windows using native Windows APIs (not MSYS or Cygwin). This patch series is at the point where it basically now works. I can run the server with the memory plugin, and access it remotely using guestfish, creating filesystems and so on without any apparent problems. Nevertheless there are many

Also available here: https://github.com/rwmjones/nbdkit/tree/2020-windows-mingw-nolib After a lot of work I have made the port to Windows work without using a separate library. Instead, on Windows only, we build an "import library" (library of stubs) which resolves references to nbdkit_* functions in the main program and fixes up the plugin, basically the first technique outlined in
