Hi, when I switch to an unsupported GCC like v4.6.4 to build LLVM v3.8-rc3 with cmake I get the following: ... -- Looking for __atomic_fetch_add_4 in atomic -- Looking for __atomic_fetch_add_4 in atomic - not found CMake Error at cmake/modules/CheckAtomic.cmake:36 (message): Host compiler appears to require libatomic, but cannot find it. Call Stack (most recent call first):

Hello, lately, I have been thinking about how to resolve the problem with that the program size increases enormously when including <iostream> when compiling with libstdc++. In this library, in <iostream> there is a static object __ioinit initialized like so: ... // For construction of filebuffers for cout, cin, cerr, clog et. al. static ios_base::Init __ioinit; ...

Hey Guys, I'm working on a project in Android related to System-level Audio DSP Effects for Tuning Android Audio. I want to leverage Faust ( https://faust.grame.fr/) to allow users to program their own filters. Faust provides a libfaust implementation which includes a JIT Compiler which leverages LLVM and seems to be the best path for me to use. Unfortunately I'm having problems

Dear LLVM developers, Hello, I'm trying to find a way of cross-compiling my c code against Baremetal Cortex-M device (so target triple will be arm-none-eabi) only using LLVM/Clang, and not using anything from GNU (ld or libc). I'm doing this to know which one of LLVM/clang and GCC produces smaller flash image size because saving flash is a big deal in our projects. 1) When I just follow

Greetings! I have been building llvm-3.6.x, 3.7.1 and 3.7.2 with (glibc-2.12.1, binutils-2.24, gcc-4.9.2) almost same set if CMake flags. However while building LLVM-3.8.0 using same CMake flags I am observing projects/libcxx/include/cmath errors... ...'::signbit' has not been declared ...'::fpclassify' has not been declared ...'::isfinite' has not been declared ...

Dear testers, 7.0.0-rc1 was just tagged (from the branch at r338847). It's early in the release process, but I'd like to find out what the status is of the branch on our various platforms. Please run the test script, share the results, and upload binaries. Thanks, Hans

Hi All, I am trying to build the 'lld' linker on Mac OS 10.9, but during the build, I am getting the errors. Following are the steps that I have followed: 1.     I have downloaded the ‘llvm-stable’ source code from the following location:   https://github.com/llvm-mirror/llvm/tree/stable   2.     Machine details(on which llvm source code isbeing built) are as follows: $ sw_vers

The configuration we’re mentioning is a 2-stage bootstrap: You need first to build without LTO your own clang, and then use it for the LTO build. — Mehid > On Sep 20, 2016, at 10:17 AM, Michael Kruse <llvmdev at meinersbur.de> wrote: > > I am the author of Polly's/ISL's platform tests and could reproduce > the problem on my system with this error message: > >

Hi renato, 1. The command above is followed by the guide[ HowToCrossCompileLLVM.rst ] and I specify some path(ex. <path-to-host-bin>). 2. The including x86_64 libraries is added because of some missing libraries(ex. "error: Host compiler appears to require libatomic, but cannot find it"). As I have found that the bugs needed to dealt with is some ARM-dependent libraries, I

It’s pretty intermittent at the moment…sometimes I get the relocation overflow issue, sometimes I get another issue about BSS sections having no contents. The source code to reproduce either is simple: #include <iostream> int main (int argc, char* argv[]) { } I’ve managed to reproduce the BSS section issue in clang consistently, and since that comes before terms of where it happens in

>because with that generator the CMAKE_BUILD_TYPE variable is ignored >because it is a "multi-configuration target". thanks for the link, is that a bug in the CMake configuration (or better not getting any warning) or is there just documentation missing? so i can use --config Debug or --config Release and get the correct results - i hope that works the build takes hours

Oops, sorry for the spam. That last comment was incorrect.
