Hi Chandler, That's embarrassing how weird this part of clang is. I have a provisional patch which fixes the problem but underlines clang's problems. I will submit it tonight for comments. суббота, 18 октября 2014 г. пользователь Chandler Carruth написал: > > On Fri, Oct 17, 2014 at 7:51 AM, Anton Korobeynikov < > anton at korobeynikov.info >

So, when performing expression evaluation, lldb trips over an assert in clang/lib/AST/RecordLayoutBuilder because ExternalFieldOffsets doesn't contain a FieldDecl that updateExternalFieldOffset expected. I found that the assert occurs when both static and non-static member variables are present. For instance, with the following, the lldb command 'expr my_test.length()' does not

I ran into an LLVM/Clang crash when attempting to do the following: 1. Build Clang from the release/9.x branch source. 2. Use the Clang from (1) to build clangd on the release/9.x branch, with LLVM_ENABLE_MODULES=On. I wrote a script to reproduce the crash: https://gist.github.com/modocache/ac366ca9673b93bb21e75d3e72162608 At the above URL, you'll find a script `repro.sh` that reproduces

FYI, this turned out to be an error of omission in LLDB in SymbolFileDWARF, because the case of a non-defining external (i.e. a static member variable) wasn't being handled with a variable lookup to dig up the location. I'll put a patch together for lldb-commits, - Ashok From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Thirumurthi, Ashok

Hi Geoff, Nothing in that backtrace leaps out at me. Based on the stack trace and description my first guess would be a clang misconfiguration rather than a JIT bug. How is that clang invocation being made? Is it from inside a callback from ORC, or is it before you add your module to the JIT? -- Lang.

Greetings, Lang and other JITters, Last week I moved our Orc v2-based app from top-of-tree to the new 11.x branch, and it no longer handles C++ code containing OpenMP directives correctly. More specifically, if I JIT compile a function containing OpenMP parallel/for pragmas, using a release version of LLVM, the code compiles and seems to work, but if I try to write the module's bitcode to

Hi, That patch was from an ongoing effort to consolidate OpenMP generation in clang. If memory serves the implementation there is still a little incomplete. It's supposed to use types from OMPConstants rather than ones it defined itself and the methods used to create the functions shouldn't need to be static. However attempting this caused a lot of errors so there might be an underlying

Kostya, all, I'm trying to build my project by clang 3.8rc1 with enabled asan (clang itself is address sanitized) and it fails on several files from my project (ISPC, https://github.com/ispc/ispc). I've reproduced this on MacOS and Linux. Please let me know if you need any other info. How to reproduce: 1) Build address sanitized clang 3.8rc1: cd /path-to-working-dir svn co

Thanks, Joseph and Johannes. I have not merged in anything, I am using the code from the repository as is. What is this -debug-only option, and to whom would I pass it? I am running our own JIT application, which uses clang to compile modules on the fly via clang::CompilerInstance::ExecuteAction(). Working on the assumption that there is a mismatch in the declared type of an OpenMP runtime

Yep, it happens three times, then crashes afterwards, since I removed the assert... arg 0: expected %struct.ident_t* got %struct.ident_t.21* value @0 = private unnamed_addr global %struct.ident_t.21 { i32 0, i32 514, i32 0, i32 0, i8* getelementptr inbounds ([23 x i8], [23 x i8]* @.str, i32 0, i32 0) }, align 8 arg 0: expected %struct.ident_t* got %struct.ident_t.21* value @1 = private

Yeah, I remember encountering that error before when getting it to pass the libomp test suite. If you have a struct named "ident_t" somewhere the compiler will rename it because of the conflict with the runtime declaration. This should be solved by casting the usage to the function type found in the definition (i.e. bitcasting a struct.ident_t.21 to struct.ident_t) which solved the

Hi Jim, thanks for replying. As mentioned in my earlier mail, I have to specify -emit-obj along with -cc1 in order to trigger codegen. This solves the problem for me. As I learned from the last email, specifying -v is a good starting point in order to see what actually is happening and tackle such problems. -- Roland ----- Original Message ----- > From: "Jim Grosbach"

clang doesn't seem to respect __attribute__((used)) in C functions. Even if I declare a function like the following: __attribute__((used)) void function(), then also it doesn't declare the function in its IR file if I don't use the function. Is there any other way to force the declaration of "unused" function declarations with clang. I have hacked in clang 6.0.0 in
