vkd3d_shader_stress compiles all the shaders specified on the command line. It does not execute them because it has no way to infer the execution environment and resources they expect, so it is mostly useful when enabling the shader validators.
It expects a shader file name compatible with the one generated by setting the environment variable VKD3D_SHADER_DUMP_PATH. --- Makefile.am | 4 +- tests/vkd3d_shader_stress.c | 167 ++++++++++++++++++++++++++++++++++++ 2 files changed, 170 insertions(+), 1 deletion(-) create mode 100644 tests/vkd3d_shader_stress.c
