I am trying to build a x86_64 to ARM cross compiler. I configured, built and installed LLVM as follows: $ ../../../src/llvm/configure --with-llvmgccdir=<llvm-root>/install/x86_64-arm/llvm-gcc-4.2 --enable-optimized --enable-jit --prefix=<llvm-root>/install/x86_64-arm/llvm --target=arm-unknown-linux-gnueabi $ make $ make install Then I configured gcc front end as follows: $

Hi Journeyer First, thank you so much for your updates on your experiments. I am currently following your steps but have found myself stuck with the following error: /usr/lib/gcc/arm-linux-gnueabi/4.6/../../../../arm-linux-gnueabi/bin/ld: this linker was not configured to use sysroots clang: error: linker command failed with exit code 1 (use -v to see invocation) I used the command string you

Hello, I'm using gold linker now to see if there can be any performance gain. Also using latest gcc version (4.4.4) and latest binutils. But when I'm compiling llvm-gcc, I'm getting this error. /home/jal/llvm-gcc-4.2-2.7.source/host-i686-pc-linux-gnu/gcc/xgcc -B/home/jal/llvm-gcc-4.2-2.7.source/host-i686-pc-linux-gnu/gcc/ -B/usr/local/arm-v7a8-linux-gnueabi/bin/

I'm getting following errors while cross compiling llvm for ARM. Please help since it is urgent and critical My gcc version is 4.2.0, 32bit Linux and target is ARM Configure options are: ./configure --host=i686-pc-linux-gnu --build=i686-pc-linux-gnu --target=armv7fl-montavista-linux-gnueabi --enable-cross --with-sysroot=/home//arm_v7_vfp_le/target/

Hello, Thank you for your kind attention to my issue and your help. I changed the tool chain and tried again. And there is a little progress but still have some problem. Using --sysroot doesn't make clang use linker(ld) in the cross tool. Most important question is how I can make clang use cross tool linker. Let me show you my experiment and questions below. There are two questions. [Run]

Sorry for not explaining well. After compiling with g++-cross g++-cross -c a.c I do link using this command /gold_binutils/build/gold/ld-new -plugin ~/Desktop/Sanjeev/LLVM/llvm-2.7/Release/lib/libLLVMgold.so --eh-frame-hdr -melf_i386 -dynamic-linker /lib/ld-linux.so.2 /usr/lib/crt1.o /usr/lib/crti.o /usr/local/lib/gcc/i686-pc-linux-gnu/4.2.0/crtbegin.o

Hello: I recently attempted to update the ARM cross-compilation setup I had with llvm, and it did not work, so I wanted to revert back to my initial configuration. I reconfigured/make/make install'ed my llvm which executed fine, and then cleared out my llvm-gcc obj and install folders, and reconfigured gcc from within llvm-gcc/obj as follows: ../llvm-gcc-4.2-2.9.source/configure

Hello list I think I really finally found a way to crossbuild a binary for ARM using Clang/llvm. This message would be a documentation for someone who may concern for the same issue with me. - Target : TOSHIBA AC100 / Ubuntu 12.04 (https://wiki.ubuntu.com/ARM/** TEGRA/AC100 <https://wiki.ubuntu.com/ARM/TEGRA/AC100>) - Host : i386 Desktop PC / Ubuntu 12.04 - Toolchain on host : sudo

Hello Gergö, Joerg and people on our list With your kind answer, I tried to build a hello world program for ARM(arm-none-linux-gnueabi) on my x86-64 PC. Thank you we verified the generated bitcode. The only thing remained is linking. Let me brief what I did so far. 1. Built Clang/llvm in a way explained in http://clang.llvm.org/get_started.html on Ubuntu 11.10 x86-64 PC 2. Downloaded gcc-4.0

> In conclusion: > Why are people using Git disadvantaged? Short answer: because of git-svn and differences between what is a tag in git and svn. Long answer: git-svn never created proper git tags. Instead, it converted svn tags to branches (because technically branches and tags are same in svn). These branches were orphan and not usable for bunch of things (I believe Takumi can provide a

Hi, Rafael took some measurements to try to investigate the effect of the local symbols changes. I've been taking a look at the measurements he got and there were some interesting things we noticed. For starters, in the range of revisions tested (r263214 through r263471), we found that the commit for --build-id was the most noticeable, with slowdowns from 7% to 23% (note: these were
