[PATCH v15 0/4] MR84: vkd3d-shader/spirv: Merge all shader IR fork and join phases into a single phase.
Normalise the incoming vkd3d_shader_instruction IR to the shader model 6 pattern where only one patch constant function is emitted. This allows generation of a single patch constant function in SPIR-V.
-- v15: vkd3d-shader/spirv: Declare the phase SPIR-V function in spirv_compiler_enter_shader_phase(). vkd3d-shader/spirv: Remove the hull shader phase array. vkd3d-shader/trace: Trace the normalised instruction array after tracing the input. vkd3d-shader/ir: Merge all shader IR fork and join phases into a single phase.
From: Conor McCarthy cmccarthy@codeweavers.com
Normalise the incoming vkd3d_shader_instruction IR to the shader model 6 pattern. This allows generation of a single patch constant function in SPIR-V. --- Makefile.am | 1 + libs/vkd3d-shader/ir.c | 264 +++++++++++++++++++++++ libs/vkd3d-shader/spirv.c | 148 ++++--------- libs/vkd3d-shader/vkd3d_shader_main.c | 78 +++++++ libs/vkd3d-shader/vkd3d_shader_private.h | 19 ++ 5 files changed, 405 insertions(+), 105 deletions(-) create mode 100644 libs/vkd3d-shader/ir.c
