From 9b4a6fa4c09d36e0e5c00309e6ea37300ea38f78 Mon Sep 17 00:00:00 2001 From: Antia Puentes Date: Wed, 17 Jun 2015 10:10:44 +0200 Subject: [PATCH] i965/nir/vec4: Mark as unreachable ops that should be already lowered NIR ALU operations: * nir_op_fabs * nir_op_iabs * nir_op_fneg * nir_op_ineg * nir_op_fsat should be lowered by lower_source mods * nir_op_fdiv should be lowered in the compiler by DIV_TO_MUL_RCP. * nir_op_fmod should be lowered in the compiler by MOD_TO_FLOOR. * nir_op_fsub * nir_op_isub should be handled by ir_sub_to_add_neg.
