This is a regression happening with the commit87b99d5797("nir: use copysign for atan"). Indeed, the opcode "copysign" was generating an incompatible i915 sequence. For instance, this issue is triggered with "deqp-gles2 --deqp-case=dEQP-GLES2.functional.shaders.operator.angle_and_trigonometry.atan2.highp_float_vertex": deqp-gles2: ../src/compiler/nir/nir_lower_int_to_float.c:239: lower_alu_instr: Assertion `nir_alu_type_get_base_type(info->output_type) != nir_type_int && nir_alu_type_get_base_type(info->output_type) != nir_type_uint' failed.
