-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, as the subject says, I was just wondering where the implementation of sys::fs::canonicalize() might be. The function is declared in llvm/Support/FileSystem.h, but I couldn't find its implementation within lib/Support. Consequently, any application using this function doesn't link. Am I missing something here? Regards, Mario -----BEGIN

Looks like it got implemented, then reverted due to buildbot breakage, and never re-committed: http://lists.cs.uiuc.edu/pipermail/llvm-co...

I'm including "JIT.h" directly in the main module, which also uses the engine. See

...not to modify the LLVM code, you can also work around this problem by using ExecutionEngine::createJIT(), which does not make the dlopen check. I suspect that code path is not well tested, so there may be additional problems if you do things that way. -Andy -----Original Message----- From: Mario Schwalbe [mailto:m3o.s6e at googlemail.com] Sent: Wednesday, May 22, 2013 11:30 AM To: Kaylor, Andrew Cc: Mario Schwalbe; LLVM Devel Subject: Re: [LLVMdev] Static linking of execution engine Am 22.05.13 19:32, schrieb Kaylor, Andrew: > If you send me details about how you're building this I'll...

Hi, I can confirm this problem. We use clang's libtooling ToolInvocation object and the second module fails to compile even through it's a completely fresh instance. Adding -fno-vectorize explicitly seems to work around this problem, but does anyone know a real fix? ciao, Mario Am 20.06.13 15:07, schrieb Alan Garny: > My application generates some C code which I then compile using

Hi, My application generates some C code which I then compile using LLVM+Clang before running it. For the compilation side of things, I have a class which one of the methods (the CompilerEngine::compileCode() method in https://raw.github.com/opencor/opencor/llvm_3.3/src/plugins/misc/Compiler/sr c/compilerengine.cpp) is based on the code from the clang-interpreter example

Hi all, I currently use LLVM 3.0 clang to compile my source code to bitcode (on a X86-64 machine) before it is later processed by a pass, like this: $ clang -m32 -O3 -S foo.c -emit-llvm -o foo.ll However, for some reason the the resulting module contains 128-bit instructions, e.g.: %6 = load i8* %arrayidx.1.i, align 1, !tbaa !0 %7 = zext i8 %6 to i128 %8 = shl nuw nsw i128 %7, 8 which the

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I know similar questions have been asked several times, but I couldn't find an answer in earlier threads. Is it safe to process several modules concurrently in different threads if they share the same LLVM context instance, i.e., is the context implementation thread-safe?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, are the llvm.memset.p0i8.i32 and llvm.memset.p0i8.i64 intrinsics meant to be used for 32-bit and 64-bit architectures, respectively depending on the module's target datalayout? Or can I use any of them? If yes, why are there two functions? Sorry, if it's obvious, but the documentation wasn't that clear. Thanks and ciao, Mario

Hi, I'm on Linux and trying to link an application that makes use of LLVM's JIT execution engine statically. Setup: (1) LLVM libs are compiled as static libraries. (2) Called InitializeNativeTarget(). (3) Included llvm/ExecutionEngine/JIT.h. It works if I build and link regularly. However, if I add -static when linking, the execution engine fails to initialize. Does anyone know why?

Hi all, although I feel like this is a too simple question, I can't find the answer right now. I have a pass that changes the alignment constraints of global variables of a module, which doesn't affect any loads and stores of them. So how do I get the loads' and stores' alignment constraints also updated to match my changes? Is there any pass that does so? Ideally without
