[Bug 35248] New: Texture lookup in vertex shader broken

           Summary: Texture lookup in vertex shader broken
           Product: Mesa
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: s3734770@mail.zih.tu-dresden.de


I ran the demo mesa-demos/src/glsl/vert-tex and fetch instructions only return
memory garbage.

The same problem appears when running games via wine where hardware skinned
models are not shown (better: vertices are spread around the whole coordinate
system)

An additional info: the texture to fetch has float texels and is a luminance
texture.

Patch: also regard vs resources

I found the problem:
077c448d184799e0d9ec962013ec784c6a5c1807 did not pay attention at vs
The fix also adds the resource offset to vs

The r600_shader_from_tgsi() change is wrong, but I've pushed the rest.

oh, we forgot to mark it "fixed".
