From 37933cb048b050624c32ebaa0ac91636dec1c557 Mon Sep 17 00:00:00 2001 From: Sergey Sharybin Date: Fri, 29 Jul 2016 18:44:29 +0200 Subject: Cycles: Add fundamentals to test constant folding This commit adds some easy to use way to check whether the graph was properly optimized. The idea is based on using mock glog sync which keeps track on all messages and expects specific log message to appear in the logging. This means each optimization step should report that it optimized something (specifying what exactly was optimized) and what was used for optimization. There's also some ease-ish way to define shader networks which we might want to make a bit more global and available for all tests in the future. For now only RGBToBW node is covered as an example, really hope to get help from active guys in the community to finish covering all existing optimization cases. Ready to fix any possible issues with builder when needed tho :) --- intern/cycles/test/CMakeLists.txt | 29 +++++ intern/cycles/test/render_graph_finalize_test.cpp | 149 ++++++++++++++++++++++ 2 files changed, 178 insertions(+) create mode 100644 intern/cycles/test/render_graph_finalize_test.cpp (limited to 'intern/cycles/test') diff --git a/intern/cycles/test/CMakeLists.txt b/intern/cycles/test/CMakeLists.txt index 2f3a4d0b1df..a6bcf980df2 100644 --- a/intern/cycles/test/CMakeLists.txt +++ b/intern/cycles/test/CMakeLists.txt @@ -14,9 +14,37 @@ endmacro() set(INC . .. + ../device + ../graph + ../kernel + ../render ../util ) +set(ALL_CYCLES_LIBRARIES + cycles_render + cycles_device + cycles_bvh + cycles_graph + cycles_kernel_osl + cycles_util + ${OPENIMAGEIO_LIBRARIES} +) +if(WITH_CYCLES_OSL) + list(APPEND ALL_CYCLES_LIBRARIES + ${OSL_LIBRARIES} + ${LLVM_LIBRARIES} + ) +endif() +if(WITH_IMAGE_OPENJPEG AND NOT WITH_SYSTEM_OPENJPEG) + list(APPEND ALL_CYCLES_LIBRARIES + extern_openjpeg + ) +endif() +list(APPEND ALL_CYCLES_LIBRARIES + ${BOOST_LIBRARIES} +) + include_directories(${INC}) link_directories(${BOOST_LIBPATH}) @@ -25,6 +53,7 @@ link_directories(${OPENIMAGEIO_LIBPATH}) set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${PLATFORM_LINKFLAGS}") set(CMAKE_EXE_LINKER_FLAGS_DEBUG "${CMAKE_EXE_LINKER_FLAGS_DEBUG} ${PLATFORM_LINKFLAGS_DEBUG}") +CYCLES_TEST(render_graph_finalize "${ALL_CYCLES_LIBRARIES}") CYCLES_TEST(util_aligned_malloc "cycles_util") CYCLES_TEST(util_path "cycles_util;${BOOST_LIBRARIES};${OPENIMAGEIO_LIBRARIES}") CYCLES_TEST(util_string "cycles_util;${BOOST_LIBRARIES}") diff --git a/intern/cycles/test/render_graph_finalize_test.cpp b/intern/cycles/test/render_graph_finalize_test.cpp new file mode 100644 index 00000000000..4566894d490 --- /dev/null +++ b/intern/cycles/test/render_graph_finalize_test.cpp @@ -0,0 +1,149 @@ +/* + * Copyright 2011-2016 Blender Foundation + * + * Licensed under the Apache License, Version 2.0 (the "License");
