From 6e499572b9a7b33165b8438a85db37ae1ba0ce0e Mon Sep 17 00:00:00 2001 From: Neil Roberts Date: Wed, 21 Mar 2018 20:34:39 +0100 Subject: [PATCH] spirv: Add a 64-bit implementation of OpIsInf The only change neccessary is to change the type of the constant used to compare against. This has been tested against the arb_gpu_shader_fp64/execution/ fs-isinf-dvec tests using the ARB_gl_spirv branch. v2: Use nir_imm_floatN_t for the constant.
