Support for AMD Pitcairn and Tahiti processors

[santzi]

Hi,

This is very nice program. I have used this now about half year.
I have AMD 7850 2GB (Pitcairn) graphic card and Debian 7.3.0, but I need to make changes to oclengine.c -file every time when I download a new repo and compiled it.
I download this repo, because this support compressed mode.

I add these two lines to oclengine.c -file and then it works like charm:
if (!strcmp(dvn, "Tahiti") || !strcmp(dvn, "Pitcairn"))
quirks &= ~VG_OCL_AMD_BFI_INT;

I now there are plenty of people who has the same problem as me had, so this change might help Pitcairn and Tahiti processors users.

oclengine.c:
case 0x1002: /* AMD/ATI /
/
* AMD's compiler works best with preprocesor unrolling.
* Pragma unroll is unreliable with AMD's compiler and
* seems to crash based on whether the gods were smiling
* when Catalyst was last installed/upgraded.
*/
if (vg_ocl_device_gettype(vocp->voc_ocldid) &
CL_DEVICE_TYPE_GPU) {
quirks |= VG_OCL_EXPENSIVE_BRANCHES;
quirks |= VG_OCL_DEEP_VLIW;
dvn = vg_ocl_device_getstr(vocp->voc_ocldid,
CL_DEVICE_EXTENSIONS);
if (dvn && strstr(dvn, "cl_amd_media_ops"))
quirks |= VG_OCL_AMD_BFI_INT;

        dvn = vg_ocl_device_getstr(vocp->voc_ocldid,
                       CL_DEVICE_NAME);
                    if (!strcmp(dvn, "Tahiti") || !strcmp(dvn, "Pitcairn"))
                            quirks &= ~VG_OCL_AMD_BFI_INT;

        if (!strcmp(dvn, "ATI RV710")) {
            quirks &= ~VG_OCL_OPTIMIZATIONS;
            quirks |= VG_OCL_NO_BINARIES;
        }
    }

br,
