[Mesa-dev] [PATCH 07/13] gallium/radeon: fix ARB_query_buffer_object conversion to boolean

[Nicolai Hähnle]

From: Nicolai Hähnle <nicolai.haehnle at amd.com>

The issue here is that the immediate is treated as a 64-bit value,
and fetching it does not work reliably with swizzles that are different
from xy and zw.
