DEVICE_EXTENSION VK_KHR_shader_terminate_invocation
|
|
|
|
# A test for a bug found by GraphicsFuzz.
|
|
|
|
# Short description: A fragment shader with an always false if function
|
|
|
|
# The test passes because main always writes the color red. (Additionally the discard statement is never reached).
|
|
|
|
# Optimized using spirv-opt with the following arguments:
