From: Connor Abbott Date: Fri, 1 Aug 2014 23:24:44 +0000 (-0700) Subject: i965/fs: Don't use ir->lod_info.grad.dPd in emit_texture_*. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eaadc431920fe31b13c11b0c78e7eb2226a920a0;p=mesa.git i965/fs: Don't use ir->lod_info.grad.dPd in emit_texture_*. This drops a dependency on ir_texture objects. v2 (Ken): Rename lod_components to grad_components, as it only has a meaningful value for ir_txd. We could set it to 1 for TXL, but there's no real need.
