From: Antia Puentes <apuen...@igalia.com> * Lowered floating-point pack and unpack operations are not valid in VS.
* Pack and unpack 2x16 operations should be handled by lower_packing_builtins. * Adds NIR ALU operations: * nir_op_pack_half_2x16 * nir_op_unpack_half_2x16 * nir_op_unpack_unorm_4x8 * nir_op_unpack_snorm_4x8 * nir_op_pack_unorm_4x8 * nir_op_pack_snorm_4x8 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89580 --- src/mesa/drivers/dri/i965/brw_vec4_nir.cpp | 41 ++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) diff --git a/src/mesa/drivers/dri/i965/brw_vec4_nir.cpp b/src/mesa/drivers/dri/i965/brw_vec4_nir.cpp index 6f16ce6..98b0c95 100644 --- a/src/mesa/drivers/dri/i965/brw_vec4_nir.cpp +++ b/src/mesa/drivers/dri/i965/brw_vec4_nir.cpp @@ -1077,6 +1077,47 @@ vec4_visitor::nir_emit_alu(nir_alu_instr *instr) case nir_op_fnoise4_4: unreachable("not reached: should be handled by lower_noise"); + case nir_op_unpack_half_2x16_split_x: + case nir_op_unpack_half_2x16_split_y: + case nir_op_pack_half_2x16_split: + unreachable("not reached: should not occur in vertex shader"); + + case nir_op_pack_snorm_2x16: + case nir_op_pack_unorm_2x16: + case nir_op_unpack_snorm_2x16: + case nir_op_unpack_unorm_2x16: + unreachable("not reached: should be handled by lower_packing_builtins"); + + case nir_op_pack_half_2x16: + op[0] = fix_swizzle_for_input_fixed_size(instr->op, op[0]); + emit_pack_half_2x16(dst, op[0]); + break; + + case nir_op_unpack_half_2x16: + op[0] = fix_swizzle_for_input_fixed_size(instr->op, op[0]); + emit_unpack_half_2x16(dst, op[0]); + break; + + case nir_op_unpack_unorm_4x8: + op[0] = fix_swizzle_for_input_fixed_size(instr->op, op[0]); + emit_unpack_unorm_4x8(dst, op[0]); + break; + + case nir_op_unpack_snorm_4x8: + op[0] = fix_swizzle_for_input_fixed_size(instr->op, op[0]); + emit_unpack_snorm_4x8(dst, op[0]); + break; + + case nir_op_pack_unorm_4x8: + op[0] = fix_swizzle_for_input_fixed_size(instr->op, op[0]); + emit_pack_unorm_4x8(dst, op[0]); + break; + + case nir_op_pack_snorm_4x8: + op[0] = fix_swizzle_for_input_fixed_size(instr->op, op[0]); + emit_pack_snorm_4x8(dst, op[0]); + break; + default: unreachable("Unimplemented ALU operation"); } -- 2.1.4 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
