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

Hello everyone, I have written simple LLVM passes, but I cannot able to write a MachineFunctionPass pass. I am following the steps form the following link but it is not working: http://www.gabriel.urdhr.fr/2014/09/26/adding-a-llvm-pass/ Please share the sample MachineFunctionPass code or steps to follow to write MachineFunctionPass. Thanks, Bala -- Thanks, Bala IIITA Allahabad --------------

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

First you should learn how to write a pass and then a MachineFunctionPass. >From LLVM website, you can refer to http://llvm.org/docs/WritingAnLLVMPass.html And for outside pass, you can refer to http://adriansampson.net/blog/llvm.html It's a great article. And the author put the source code on Github <https://github.com/sampsyo/llvm-pass-skeleton>. 2016-03-01 14:36 GMT+08:00

Hi All, I wanted to collect the register usage stats for the program assigned by compiler(in other words "how many time each register will be accessed by the program when it will execute"). How to write LLVM pass which will analyse the code after LLVM global register allocation pass and output the stats. Regards, -Bala -- Thanks, Bala IIITA Allahabad -------------- next part

Hello All, I have converted c program into assembly code for alpha target using following commands clang -emit-llvm matrix.c -c -o matrix.bc llc -march=alpha matrix.bc -o matrix.s Now how to convert matrix.s assembly file into executable file of alpha target? Any help is appreciated Thanks in advance !! Thanks, Bala -------------- next part -------------- An HTML attachment was scrubbed...

Hi James, renato, So how do I download the missing ARM libraries on Ubuntu14.04? I cannot find any available libraries.

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

Deer All, I wanted to write MachineFunctionPass which needs to be run after global register allocation pass. I have read LLVM documentation and blogs and able to write simple pass which will is invoked through opt command line. However, I could able to find any blogs or document to explains clear steps for writing MachineFunctionPass. Please suggest some documents or blogs which will help me

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

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`

How do I cross-compile compiler-rt for ARM-Linux with CMake? Given a directory with sub-directories named 'llvm', 'compiler-rt', and 'release' (which is a clang build directory), this build succeeds: $ mkdir -p release-rt $ cd release-rt $ cmake ../llvm -G Ninja \ -DCMAKE_INSTALL_PREFIX=ship \ -DCMAKE_BUILD_TYPE=Release \ -DLLVM_ENABLE_ASSERTIONS=ON \

where should the file build_llvm_package.bat be placed and how should the build_llvm_package.bat be called? or is there a another way to do a two stage build of the llvm project on windows starting with using visual studio 2017 community. -------------- next part -------------- An HTML attachment was scrubbed...

Hello, I am trying to cross-compile libc++ from my x86_64 linux system to armv7hf. We have our own gcc compiler that we build with crosstools-ng (based on gcc 6.3.0) and I set my environment like this: CC=armv7a-plex-linux-gnueabihf-gcc CXX=armv7a-plex-linux-gnueabihf-g++ CFLAGS=-fPIC -DPIC -mfloat-abi=hard -march=armv7-a -Os -mfpu=vfpv3-d16 --sysroot=<path> CXXFLAGS=-fPIC -DPIC

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

At first glance, it looks like long double functions (such as fabsl and friends) are missing from your sysroot's <math.h>. Does your target support long double at all? -Dimitry > On 6 Feb 2018, at 09:51, Tobias Hieta via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Hello, > > I am trying to cross-compile libc++ from my x86_64 linux system to armv7hf.

Hello Dimitry and thanks for your answer. I am pretty sure it does indeed support long double. It's configured with vfpv3-d16 - but I noticed that c++config.h in gcc has _GLIBCXX__HAS_FABSL and friends are undefined. I think I need to look deeper at the configuration of our toolchain. long double support is required in libc++ then I gather? -- Tobias On Tue, Feb 6, 2018 at 11:47 AM,

Hello, I'm trying to cross compile the MiBench benchmarks using LLC and ARM cross compiler the binaries generated will be used on pandaboard or the qemu-arm emulator. I have faced multiple issues during the compilation process, here are the commands used. # generate LLVM-IR for dijkstra_large.c $gcc -S -flto -o dijkstra_large.bc -fplugin=${DRAGONEGG} dijkstra_large.c # generate TARGET

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
