similar to: Mach-O support in lld: what are the known issues?

I'd be interested in the existence of a high-quality, open-source, portable linker for apple platforms, but not enough to help make that happen. If I _was_ gonna work on something related to that, I'd probably be inclined to instead add any required features to allow an ELF linker to target a notional darwin-elf target, and to have clang emit darwin-elf object files, and then write a

Is it possible to get a premade query for bugs whom have not had activity for 6+ months? There was one as a sticky in the past. Thanks!

MJ, I put some extra info on this for the list. This is a new Debian Jessie install with sernet samba packages. The Keytab file is not created with sernet 4.6.1 packages but it is with the sernet 4.5.7 samba packages. Bug list show some keytab reported but i dont see any related to this.

Thank you for the link and the suggestion to try master! I did so and discovered that it reproduces on master for me as well. The repro script I used (unchanged from before) and the output can be found here: https://gist.github.com/modocache/d9700166067f4a155820bc57d9bee1f3 (Note that the output looks nearly identical, but it's using clang-10 from the master branch of llvm-project.) I wonder

An important goal here is to provide analysis (and other) tools to users that present this information at a higher level. The users won't, and shouldn't, know exactly what kinds of messages the tools use.

If you call lld::coff::link twice, the second time gives this backtrace: msvcp140d.dll!00007ffc35830806() Unknown > zig.exe!std::_Debug_pointer<lld::coff::Chunk * __ptr64 const>(lld::coff::Chunk * const * _Ptr, const wchar_t * _File, unsigned int _Line) Line 926 C++ zig.exe!std::_Debug_range2<lld::coff::Chunk * __ptr64 const * __ptr64>(lld::coff::Chunk * const *

Hello! (+cc Adam Nemet, since he presented on optimization remarks at LLVM Dev Mtg 2016) I have a large C++ program, which I am compiling using a sampling profile generated via perf and AutoFDO. I'd like to use this profile in order to show the hotness of each code path that is displayed in the new optimization remarks viewer tool ( https://www.youtube.com/watch?v=qq0q1hfzidg). It seems,

I'm copying some LLD code into my codebase like this: // workaround for LLD not exposing ability to convert .def to .lib #include <set> namespace lld { namespace coff { class SymbolBody; class StringChunk; struct Symbol; struct Export { StringRef Name; // N in /export:N or /export:E=N StringRef ExtName; // E in /export:E=N SymbolBody *Sym = nullptr; uint16_t Ordinal

Zig tests using Debug build of 5.0.1rc2 hit this bug: https://bugs.llvm.org/show_bug.cgi?id=34452 I suppose the fix has not been backported to 5.0.1. So I created a Release build of 5.0.1rc2 and all zig tests pass, with the following patches: * Patches to LLD: commit a206ef34bbbc46017e471063a4a1832c1ddafb0a Author: Andrew Kelley <superjoe30 at gmail.com> Date: Fri Dec 1 12:11:55 2017

Hello all, It's been a month since my previous email on the topic, and since then I've done some initial work on porting the coroutines passes to the new pass manager. In total there are 6 patches -- that's a lot to review, so allow me to introduce the changes being made in each of them. # What's finished In these first 6 patches, I focused on lowering coroutine intrinsics

Adam, thanks for all the suggestions! One nice aspect of the `-Rpass` family of options is that I can filter based on what I want. If I only want to see which inlines I missed, I could use `clang -Rpass-missed="inline"`, for example. On the other hand, optimization remark YAML always include remarks from all passes (as far as I can tell), which increases the amount of time it takes

I saw this change come in yesterday: commit 572ad839e2f66eaa82ffc71b1061eb3d06a4d126 Author: Saleem Abdulrasool <compnerd at compnerd.org> Date: Thu Jun 15 20:39:58 2017 +0000 COFF: add support for lib mode usage When link is invoked with `/def:` and no input files, it behaves as if `lib.exe` was invoked. Emulate this behaviour, generating the import library from the

Hello all! I find that using lldb to debug LLVM libraries can be super frustrating, because a lot of LLVM classes, like the constructor for StringRef, are marked LLVM_ATTRIBUTE_ALWAYS_INLINE. So when I attempt to have lldb evaluate an expression that implicitly instantiates a StringRef, I get 'error: Couldn't lookup symbols: __ZN4llvm9StringRefC1EPKc'. As an example, most recently

So, 90% of the time I've seen this, it was memory corruption, usually use after free. I know I fixed one after 5.0 branched. You should compile with address sanitizer enabled, and I suspect you will find the issue quicky. If not, we really need ir that reproduces it.

Hello all, In https://www.youtube.com/watch?v=qq0q1hfzidg, Adam Nemet (cc'ed) describes optimization remarks and some future plans for the project. I had a few follow-up questions: 1. As an example of future work to be done, the talk mentions expanding the set of optimization passes that emit remarks. However, the Clang User Manual mentions that "optimization remarks do not really make

Vedant, Jeremy, Thanks a ton! I copied ASan's use of 'replaceDbgDeclare', think that worked! https://github.com/modocache/llvm-project/commit/afbc04e1dcba has some extremely quick and dirty changes I made (with no tests!), and a link to a Gist with the LLVM IR and DWARF produced, https://gist.github.com/modocache/6f29093ba2827946011b422ed3bd2903. There's only one kink: the spot

Hi Mikhail, As Brian noted, stuff like this works better in the new pass manager. Even in the old pass manager I thought it should work though. Did you initialize the pass, via `INITIALIZE_PASS_DEPENDENCY(PostDominatorTreeWrapperPass)`? Did you require it, via ` AU.addRequired<PostDominatorTreeWrapperPass>();`? Btw. May I ask what you are planning to do? Cheers, Johannes On 01/07,

I have this code, which works fine on MacOS and Linux hosts: const char *target_specific_cpu_args; const char *target_specific_features; if (g->is_native_target) { target_specific_cpu_args = ZigLLVMGetHostCPUName(); target_specific_features = ZigLLVMGetNativeFeatures(); } else { target_specific_cpu_args = ""; target_specific_features =
