From 0e0dc596a2c008c32def103e175fcd5b7116f38f Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Wed, 10 Oct 2018 22:04:17 -0500 Subject: [PATCH] intel/vec4: Fix nir_op_b2[fi] with 64-bit result This is valid NIR but you can't actually hit this case today. GLSL IR doesn't have a bool to double opcode; it does f2d(b2f(x)). In SPIR-V we don't have any to/from bool conversion opcodes at all. However, the next commit will make us start generating it so we should be ready.
