From ef8082baf860cb19cbb8c6435e9144ff16b3429f Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Fri, 9 Feb 2018 17:17:31 +1100 Subject: [PATCH] ac: convert nir_op_f2f32 src to a float Fixes the following piglit test: ./bin/arb_vertex_attrib_64bit-check-explicit-location -auto -fbo Where we would end up with the nir such as: vec1 64 ssa_11 = pack_64_2x32_split ssa_9, ssa_10 vec1 32 ssa_12 = f2f32 ssa_2 And our pack_64_2x32_split nir to llvm code always produces a 64bit integer as output.
