I'm trying the FFT sample on a Ubuntu 11.04 with a FX-8150 and 4 Firepro 3d V5800
My hardware:
Motherboard: MSI FX990-GD80
CPU: AMD FX 8150 3.6 GHz
RAM: 32Gb
4x FirePro 3d V5800
OS Ubuntu 11.04
Drivers and SDK:
FirePro_8.911.3.1_Linux_X32X64_132092.zip
AMD-APP-SDK-v2.6-lnx64.tgz
The FFT sample runs fine on the GPUs:
valerio@hotshot:~$ /opt/AMDAPP/samples/opencl/bin/x86_64/FFT --device gpu

LLVM ERROR: Error parsing inline asm
I seems that the llvm compiler, when run on a bulldozer cpu generates code for a valid instruction that is unknown to the assembler.
Is this a known problem? Am I doing something wrong?
Thanks,
Valerio
