Hello Anton, Thanks for replying. The message "as: unrecognized option `-mcpu=cortex-a8'" is the same message I get when I just enter: as -mcpu=cortex-a8 So I think I llvm-gcc is using the Linux i386 assembler to assemble ARM code. Not good. What assembler is it supposed to use? The one in CodeSourcery? > But how's assembler actually called? Just try to compile

We've only added support for ARMv7 (including cortex-a8) in llvm in the last week or so, and the associated changes for llvm-gcc are still pending. Unless you need specific

Ok, we're getting there... ;) I think these errors are due to Clang not finding the libraries/includes/etc for the target you're building. If you have

I am trying to compile llvm-gcc for an ARm target. I usine the following configure options: /home/tony/llvm/llvm-gcc/configure --prefix=/home/tony/llvm/llvm-gcc-install/ --program-prefix=llvm-arm- --enable-llvm=/home/tony/llvm/llvm-install/ --enable-pic --disable-bootstrap --target=arm-none-linux-gnueabi --enable-languages=c,c++ Then I try to make: make ENABLE_PROFILING=1 ENABLE_OPTIMIZED=1

I place codesourcery toolchain 2010q1 there, but the sh tell me "CodeSourcery tarball not found in /root/tmp/arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 ", does 2007q3 support ARM Cortex A8?

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

hi all We want speed up our applications, so we want use llvm-gcc. I nerver cross build it for arm, and I didn't find enough information in llvm docs. Our cpu is cortex a8, anybody tell me how can I do? Step by step. THANK YOU! yours Liu -------------- next part -------------- An HTML attachment was scrubbed... URL:

Thanks John, I just realized that I am not working on the same "branch" of LLVM. Looking the latest or the newest version I saw the folder with the script, but I did not see a README file. I ran the script, and I get: ********** chown: cannot access `/usr/local/codesourcery': No such file or directory ********** Therefore my question is if the script depends on others folders (or

hi My host is Linux on x86, and I want llvm-gcc generate code for Arm Cortex-A8. I saw that in LLVM 2.7 Release Notes, but I can't find step to build it. Anyone tell me? llvm-gcc now has complete support for the ARM v7 NEON instruction set. This support differs slightly from the GCC implementation. Please see the ARM Advanced SIMD (NEON) Intrinsics and Types in LLVM Blog

Hello, I asked here for kind of reference GCC version which LLVM development team is using for *native* testing on ARM hardware. (no cross compilation!) last week or so. I've been curious myself how the situation looks and so I tested LLVM 2.9 as a reference point and LLVM HEAD as of June 29 on ARMv7 (two boards with two different Ubuntu versions) compiled by GCC 4.3.4, 4.4.1, 4.4.5,
