similar to: [LLVMdev] gcc cross compiler for arm works :-)

Hi,    I use the crosstool build script to build a crosscompiler for ARM. I get the following error when compilng "helloworld" program:   llvm-gcc hello.c -o hello   as: unrecognized option `-meabi=4'   I know that the reason is not to get proper cross assembler. It tries to use the native assembler but I am unable to fix the problem. I use llvm-gcc -### hello.c -o hello and see

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, 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/

Hello, I am trying to cross compile LLVM. Build and compile on Mac OS X 10.5.7 Target is an Angstrom Linux Cortex-A8 Beagle board. I would like to avoid GPLv3. I can compile. But when I run my executable on Beagle crt0.S is calling an AngelSWI to setup the heap and stack. But the AngelSWI seems to just be a stub because it returns zeros for the pointers. That leads to a segfault. If I hack in

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

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 In my install directory under bin , I had llvm-c++,llvm-g++,llvm-gconv I tested one sample program #llvm-c++ addu.c -o addu-arm as: unrecognized option '-meabi=4' How do i solve this issue Thanks Yuvi R On Fri, Jul 8, 2011 at 9:21 AM, raj raja <yuvaraj.addu at gmail.com> wrote: > Thanks for your reply > > I got error > > */bin/sh: build/genmodes: not

Hello Misha, I used the snapshots for the latest stable version (70786), and I followed the instructions inside of README file (very clear!!!) However, when I ran the hello program, I get an unrecognized option message. Bellow are the details. ============================================ jcmartin78 at jcmartin78-laptop:~/LLVM/my-test$ llvmc hello.c as: unrecognized option '-meabi=4'

Hi, Any help would b appreicated. This is one of my critical assignment.

Hello, Thanks for the reply. We have an product whose one part has lot of algorithms doing some graphics work. Our intention was to figure out if there can be any performance gain if we use llvm instead of native ARM. This is for ARM target. Earlier, I have built this component using llvm and tested it on x86. Performance was 4x as compared to native gcc. Then I built llvm for ARM and tested

Hi, I have cross-compiled just the basic samba 4.0.6 using bitbake recipe for ARM, which succeeded. However the resulting binaries are large in size. I used the exact same configuration options in both the cases. There is at least a 10 fold increase in the smbd compared to native x86. --- Native x86 ---- -rwxr-xr-x 1 pranavd users 92979 May 31 10:57 /usr/sbin/smbd -rwxr-xr-x 1 pranavd users

I suspect that my llvm-gcc cross compiler is using the wrong assembler because it does not recognize "-mcpu=cortex-a8". I was trying to build a cross compiler for a Mac host. Now I am trying to build on x86_64 Linux. I am targeting a Beagle board with an ARM Cortex-A8 and Angstrom Linux. TRIED: to use the script in llvm/utils/crosstool/ARM/build-install-linux.sh I used the recommended

my g++-cross was configured with following parameters: ./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/ --with-build-sysroot=/home/arm_v7_vfp_le/target/ --enable-shared --enable-languages=c,c++ --with-as=/home/arm_v7_vfp_le/bin/arm_v7_vfp_le-as

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
