[PATCH v7 0/7] MR607: vkd3d-shader/ir: Introduce a simple CFG structurizer.
This goes atop !598 and !603. -- v7: vkd3d-shader/ir: Introduce a simple control flow graph structurizer. vkd3d-shader/ir: Handle PHI nodes when materializing SSA registers. vkd3d-shader/ir: Materialize SSA registers to temporaries. vkd3d-shader/spirv: Support bool TEMP registers. vkd3d-shader/spirv: Move bool casting helpers above register loading helpers. vkd3d-shader/dxil: Set the register before calling src_param_init_scalar(). vkd3d-shader/spirv: Convert the swizzle according to the source bit width. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/607

From: Giovanni Mascellani <gmascellani(a)codeweavers.com> For simplicity PHI nodes are not currently handled. The goal for this pass is to make the CFG structurizer simpler, because it doesn't have to care about the more rigid rules SSA registers have to satisfy than TEMP registers. It is likely that the generated code will be harder for downstream compilers to optimize and execute efficiently, so once a complete structurizer is in place this pass should be removed, or at least greatly reduced in scope. --- libs/vkd3d-shader/ir.c | 81 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 81 insertions(+) diff --git a/libs/vkd3d-shader/ir.c b/libs/vkd3d-shader/ir.c index a0d6212cb..b92a04b2e 100644 --- a/libs/vkd3d-shader/ir.c +++ b/libs/vkd3d-shader/ir.c @@ -2637,6 +2637,84 @@ fail: return VKD3D_ERROR_OUT_OF_MEMORY; } +static void materialize_ssas_to_temps_process_src_param(struct vkd3d_shader_parser *parser, struct vkd3d_shader_src_param *src); + +/* This is idempotent: it can be safely applied more than once on the + * same register. */ +static void materialize_ssas_to_temps_process_reg(struct vkd3d_shader_parser *parser, struct vkd3d_shader_register *reg) +{ + unsigned int i; + + if (reg->type == VKD3DSPR_SSA) + { + reg->type = VKD3DSPR_TEMP; + reg->idx[0].offset += parser->program.temp_count; + } + + for (i = 0; i < reg->idx_count; ++i) + if (reg->idx[i].rel_addr) + materialize_ssas_to_temps_process_src_param(parser, reg->idx[i].rel_addr); +} + +static void materialize_ssas_to_temps_process_dst_param(struct vkd3d_shader_parser *parser, struct vkd3d_shader_dst_param *dst) +{ + materialize_ssas_to_temps_process_reg(parser, &dst->reg); +} + +static void materialize_ssas_to_temps_process_src_param(struct vkd3d_shader_parser *parser, struct vkd3d_shader_src_param *src) +{ + materialize_ssas_to_temps_process_reg(parser, &src->reg); +} + +static enum vkd3d_result materialize_ssas_to_temps(struct vkd3d_shader_parser *parser) +{ + struct vkd3d_shader_instruction *instructions = NULL; + size_t ins_capacity = 0, ins_count = 0, i; + + if (!reserve_instructions(&instructions, &ins_capacity, parser->program.instructions.count)) + goto fail; + + for (i = 0; i < parser->program.instructions.count; ++i) + { + struct vkd3d_shader_instruction *ins = &parser->program.instructions.elements[i]; + size_t j; + + if (ins->handler_idx == VKD3DSIH_PHI) + { + WARN("Unhandled PHI when materializing SSA registers.\n"); + vkd3d_shader_parser_error(parser, VKD3D_SHADER_ERROR_VSIR_NOT_IMPLEMENTED, + "Unhandled PHI when materializing SSA registers."); + vkd3d_free(instructions); + return VKD3D_ERROR_NOT_IMPLEMENTED; + } + + for (j = 0; j < ins->dst_count; ++j) + materialize_ssas_to_temps_process_dst_param(parser, &ins->dst[j]); + + for (j = 0; j < ins->src_count; ++j) + materialize_ssas_to_temps_process_src_param(parser, &ins->src[j]); + + if (!reserve_instructions(&instructions, &ins_capacity, ins_count + 1)) + goto fail; + + instructions[ins_count++] = *ins; + } + + vkd3d_free(parser->program.instructions.elements); + parser->program.instructions.elements = instructions; + parser->program.instructions.capacity = ins_capacity; + parser->program.instructions.count = ins_count; + parser->program.temp_count += parser->program.ssa_count; + parser->program.ssa_count = 0; + + return VKD3D_OK; + +fail: + vkd3d_free(instructions); + + return VKD3D_ERROR_OUT_OF_MEMORY; +} + enum vkd3d_result vkd3d_shader_normalise(struct vkd3d_shader_parser *parser, const struct vkd3d_shader_compile_info *compile_info) { @@ -2652,6 +2730,9 @@ enum vkd3d_result vkd3d_shader_normalise(struct vkd3d_shader_parser *parser, { if ((result = lower_switch_to_if_ladder(&parser->program)) < 0) return result; + + if ((result = materialize_ssas_to_temps(parser)) < 0) + return result; } else { -- GitLab https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/607

From: Giovanni Mascellani <gmascellani(a)codeweavers.com> The structurizer is implemented along the lines of what is usually called the "structured program theorem": the control flow is completely virtualized by mean of an additional TEMP register which stores the block index which is currently running. The whole program is then converted to a huge switch construction enclosed in a loop, executing at each iteration the appropriate block and updating the register depending on block jump instruction. The algorithm's generality is also its major weakness: it accepts any input program, even if its CFG is not reducible, but the output program lacks any useful convergence information. It satisfies the letter of the SPIR-V requirements, but it is expected that it will be very inefficient to run on a GPU (unless a downstream compiler is able to devirtualize the control flow and do a proper convergence analysis pass). The algorithm is however very simple, and good enough to at least pass tests, enabling further development. A better alternative is expected to be upstreamed incrementally. Side note: the structured program theorem is often called the Böhm-Jacopini theorem; Böhm and Jacopini did indeed prove a variation of it, but their algorithm is different from what is commontly attributed to them and implemented here, so I opted for not using their name. --- libs/vkd3d-shader/ir.c | 147 ++++++++++++++++++++++++- tests/hlsl/conditional.shader_test | 2 +-
