You are right. Thanks! I fixed that one as well as some other issues. I built LLVM-8 with Debug + no-rtti. But it now has the following error: Stack dump: 0. Program arguments: clang-8 -cc1 -triple x86_64-unknown-linux-gnu -emit-llvm -disable-free -main-file-name time-1.7.c -mrelocation-model static -mthread-model posix -mdisable-fp-elim -fmath-errno -masm-verbose -mconstructor-aliases

Hi David, I understand what you say, but have you actually read my messages? I don’t think so, Anyway, I will repost the question in case someone else can help.

Hello, I am building the SPEC 2006 Benchmark with Clang as the compiler. I have written a function pass in LLVM and I am trying to run that for SPEC by invoking the pass in the build options of SPEC. The build options of SPEC are in a *.cfg config file, which allows us to specify the choice of compiler while building SPEC. (https://www.spec.org/cpu2006/Docs/install-guide-unix.html) The pass

Hi David, Thank you for your patience but I still don’t get it: I don’t see how that is a “command”, as it’s just a list of strings that state command options. I know how to use the debugger, this is what I attempt to debug: clang --target=msp430 -emit-llvm -c -S -Oz main.c The debugger works fine, but only on the main thread. However breakpoints do not work with the code that was invoked

Sorry Zach, my apologies. I understood now what you mean. I tried and it works!. But now I found that LLVM_DEBUG statements and other output to the console doesn’t show. How do I get that back?.

Hi, I have a case that for pointer with address space attribute, pointer arithmetic is not work. For example, -bash-4.4$ cat test.c #define __user __attribute__((address_space(1))) void __user * test(void __user *arg) { #ifdef ADD return arg + 4; #else return arg; #endif } -bash-4.4$ -bash-4.4$ clang -g -c test.c -bash-4.4$ clang -g -c -DADD test.c clang-10: ../lib/IR/Instructions.cpp:2749:

Hello there, I'm building a Linux distribution based on musl and LLVM as default toolchain (including lld/libc++/libc++abi/libunwind rather than GNU). For most of the time this works pretty well. However I'm having troubles with few packages, webkit for instance fails because of max_align_t being redeclared in musl's stddef.h I see that stddef.h is provided by both musl and in the

Hello, I'm trying to create a pure LLVM toolchain (that will not depend on GNU and produce GNU-free code too) on a musl based distribution. For now, I use gcc to bootstrap and build all LLVM components. I do it individually because I was running out of space and memory trying to build all using LLVM_ENABLE_PROJECTS. Also, I don't want to create a all-in-one package. Then, once

Thanks for the detailed info! The problem was that I tried without assertions and didn't inspect the IR closely as it contained this, for now, illegal instruction: %6 = bitcast i8* %5 to i8 addrspace(1)* This is clearly a clang error. I suggest opening a bug report, or sending the reproducer to cfe-dev at llvm.lists.org so someone will take a look that has more clang experience. @Matt Do

[ Please CC me I am not subscribed to mesa-dev and llvmdev MLs ] Hi, I already reported this when playing 1st time with my llvm-toolchain v3.6.0rc2 and mesa v10.3.7 [1]. The issue still remains in mesa v10.4.4. So, this is a field test to see if LLVM/Clang v3.6.0rc2 fits my needs. I see the following build-error... ... make[4]: Entering directory

I need some help figuring out existing pass problem. I've submitted a CL on Friday (http://reviews.llvm.org/rL262103) that broke _only_ armv7 & aarch64 bots: "Pass 'SanitizerCoverageModule' is not initialized." (it was rolled back). Today I've obtained access to aarch64 machine today, applied the patch and check-all passes without any issues (terminal capture at the

I am trying to build chromium and at this moment, They see some issues with internal one so recommended to use the flag -fno-integrated-as.

Hi all, I've been trying to extend pointer size of the X86 target to 128 bits. For the prortype, I would like nothing more than the pointers being i128 type with the same value as before. All I've done was changing the data layout string to p:128:128 and when trying to run a basic program such as: int a = 42; int *p = &a; it segfaults with the following stack trace: #0

I have managed to compile llvm and clang against musl, but it behaves really strange: At first I tried to launch the compiler with musl dynamic loader: $ LD_LIBRARY_PATH=/path/to/musl/lib /path/to/musl/lib/ld-musl-x86_64.so.1 /path/to/llvm/bin/clang -v clang version 4.0.0 (https://github.com/llvm-mirror/clang 40adebeca0f99006d407508653c2cbd270a1a51c) (https://github.com/llvm-mirror/llvm

It's hard to tell what is wrong without a concrete example. E.g., what is the program you are instrumenting? What is the definition of the hook function? How did you link that definition with the binary? One thing suspicious to me is that you may have linked the definition of _Cool_MemRead_Hook as a host function instead of a device function. AFAIK, PTX assembly cannot be linked. So, if you
