From 80b1707e26734ac9c957cfc876ab5893f1749c74 Mon Sep 17 00:00:00 2001 From: Martin Peres Date: Tue, 11 Aug 2015 17:42:12 +0300 Subject: nir: convert the glsl intrinsic image_size to nir_intrinsic_image_size v2, review from Francisco Jerez: - make the destination variable as large as what the nir instrinsic defines (4) instead of the size of the return variable of glsl. This is still safe for the already existing code because all the intrinsics affected returned the same amount of components as expected by glsl IR. In the case of image_size, it is not possible to do so because the returned number of component depends on the image type and this case is not well handled by nir. v3: - Style fix Signed-off-by: Martin Peres Reviewed-by: Francisco Jerez --- src/glsl/nir/glsl_to_nir.cpp | 21 +++++++++++++++------ src/glsl/nir/nir_intrinsics.h | 2 ++ 2 files changed, 17 insertions(+), 6 deletions(-) (limited to 'src') diff --git a/src/glsl/nir/glsl_to_nir.cpp b/src/glsl/nir/glsl_to_nir.cpp index 77327b6c74f..913f2f4daca 100644 --- a/src/glsl/nir/glsl_to_nir.cpp +++ b/src/glsl/nir/glsl_to_nir.cpp @@ -641,6 +641,8 @@ nir_visitor::visit(ir_call *ir) op = nir_intrinsic_image_atomic_comp_swap; } else if (strcmp(ir->callee_name(), "__intrinsic_memory_barrier") == 0) { op = nir_intrinsic_memory_barrier; + } else if (strcmp(ir->callee_name(), "__intrinsic_image_size") == 0) { + op = nir_intrinsic_image_size; } else { unreachable("not reached"); } @@ -666,7 +668,8 @@ nir_visitor::visit(ir_call *ir) case nir_intrinsic_image_atomic_or: case nir_intrinsic_image_atomic_xor: case nir_intrinsic_image_atomic_exchange: - case nir_intrinsic_image_atomic_comp_swap: { + case nir_intrinsic_image_atomic_comp_swap: + case nir_intrinsic_image_size: { nir_ssa_undef_instr *instr_undef = nir_ssa_undef_instr_create(shader, 1); nir_instr_insert_after_cf_list(this->cf_node_list, @@ -681,6 +684,17 @@ nir_visitor::visit(ir_call *ir) instr->variables[0] = evaluate_deref(&instr->instr, image); param = param->get_next(); + /* Set the intrinsic destination. */ + if (ir->return_deref) { + const nir_intrinsic_info *info = + &nir_intrinsic_infos[instr->intrinsic]; + nir_ssa_dest_init(&instr->instr, &instr->dest, + info->dest_components, NULL); + } + + if (op == nir_intrinsic_image_size) + break; + /* Set the address argument, extending the coordinate vector to four * components. */ @@ -721,11 +735,6 @@ nir_visitor::visit(ir_call *ir) instr->src[3] = evaluate_rvalue((ir_dereference *)param); param = param->get_next(); } - - /* Set the intrinsic destination. */ - if (ir->return_deref) - nir_ssa_dest_init(&instr->instr, &instr->dest, - ir->return_deref->type->vector_elements, NULL); break; } case nir_intrinsic_memory_barrier: diff --git a/src/glsl/nir/nir_intrinsics.h b/src/glsl/nir/nir_intrinsics.h index bc6e6b8f498..6c7a61a8477 100644 --- a/src/glsl/nir/nir_intrinsics.h +++ b/src/glsl/nir/nir_intrinsics.h @@ -123,6 +123,8 @@ INTRINSIC(image_atomic_or, 3, ARR(4, 1, 1), true, 1, 1, 0, 0) INTRINSIC(image_atomic_xor, 3, ARR(4, 1, 1), true, 1, 1, 0, 0) INTRINSIC(image_atomic_exchange, 3, ARR(4, 1, 1), true, 1, 1, 0, 0) INTRINSIC(image_atomic_comp_swap, 4, ARR(4, 1, 1, 1), true, 1, 1, 0, 0) +INTRINSIC(image_size, 0, ARR(), true, 4, 1, 0, + NIR_INTRINSIC_CAN_ELIMINATE | NIR_INTRINSIC_CAN_REORDER) #define SYSTEM_VALUE(name, components) \ INTRINSIC(load_##name, 0, ARR(), true, components, 0, 0, \ -- cgit v1.2.3
