similar to: [LLVMdev] compiler-rt for ARM-Linux with CMake?

Hi, I am trying to cross compile release-10.x to AArch64 (target=aarch64-linux-gnu), and the directions listed at [1] are not completing the initial cmake step. I'm currently running Manjaro, with the aarch64-linux-gnu package (and associated binutils, headers, and glibc packages). My cmake command is cmake -DCMAKE_CROSSCOMPILING=True -DCMAKE_INSTALL_PREFIX=`realpath install`

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

Are there any sanitizer lit tests in non-X86 configurations? For example: $ cmake -DLLVM_TARGETS_TO_BUILD=ARM \ -DLLVM_DEFAULT_TARGET_TRIPLE=arm-none-linux-gnueabi \ -DLLVM_TARGET_ARCH=arm-none-linux-gnueabi All ASan tests were removed from the build and all the other sanitizers have tests but they all fail. Should they all be disabled too? Or can we add a REQUIRES tag to get lit to

Yes, I think we should disable sanitizer tests on these platforms. What is the exact line you use to configure build tree, and the output you see?

Correct. > If yes, then we should modify compiler-rt CMake rules to check if just-built Clang can target the host system and avoid running any sanitizer tests otherwise. Hmm, depends on the tests, I suppose. If the test runs the executable, then yes it should be disabled (or prefixed with an emulator (i.e.

Hello All, I am building llvm-clang tool chain for *arm target* by following the steps from http://clang.llvm.org/docs/CrossCompilation.html *However when I tried following cmake command for build tool chain it gives the error message :* #CC='clang' CXX='clang++' cmake -G Ninja /home/iiita/llvm-exp/llvm -DCMAKE_CROSSCOMPILING=True

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

Hello All, I am building llvm-clang cross tool chain for arm target, after successful build for Linux host now I am now building toolchain for *arm target*. However, I am getting below error message which seems to be confusing and not getting any idea how to resolve this issue. *Command :* #CC='clang' CXX='clang++' cmake -G Ninja /home/iiita/crossbuild/llvm

> Not that I know of, and I always build compiler-rt natively, together with Clang and LLVM. :( Do you mean "natively on ARM" or "natively on X86 with the ARM target enabled"? If the former, do you have a script to merge the target libs into the host's install directory? If the latter, that'll only build the X86 versions of the compiler-rt libraries. > Would

Hello All, I need some help with respect to cross compiling for ARM. While trying to cross compile for the ARM target, I am hitting some errors. I need some help in this. I use the following command to cross compile for ARM Cortex A72 (ARM v8-a), 64 bit architecture: *cmake -v CC='clang' CXX='clang++' -DCMAKE_C_COMPILER=../build_directory_llvm/bin/clang

I need to correct myself. It is possible to cross compile it on Windows, but not using the provided build systems.

Hi, I am trying to build a completely GNU free linux toolchain for the raspberry pi. I successfully managed to compile llvm and clang for armv7 hard float ( both as a cross compiler and as a native compiler ) together with the following: Llvm with clang and lld Clang builtins Musl libc libc++, libc++abi, libunwind All works well with the only thing to notice being the need to use -fPIC in

Hi Fellows, The goal is to find the induction variable for a loop, where the induction variable increments with the multiplication, division or shift operations, like this one: sz = 8; do { ... ... sz = sz / 2; } while (sz) Is SCEV capable of detecting the induction variable 'sz' in this case? The code snippet I am using to solve the problem is for each basic-block in a

I found https://www.llvm.org/docs/HowToCrossCompileLLVM.html. Is it enough for --sysroot? In case it is,
