I think there are a few more texture-related patches in my nir-i965-fs
branch which you don't have here, namely:
i965/fs: don't pass through the coordinate type
i965/fs: be more careful about types when emitting textures
Like the one fixing integer texture swizzles, I only realized I needed
these after I started working on the NIR backend, so I never sent them
as part of the original series, but it seems to me like they should
probably be in there (and it's likely that they have conflicts too).
Did you miss them?
