+DEVICE_EXTENSION VK_KHR_shader_terminate_invocation
+
+# A test for a bug found by GraphicsFuzz.
+
+# Short description: Calls a function containing a discard
+
+# The test passes because main always writes the color red.
+
+# Optimized using spirv-opt with the following arguments:
+# '--eliminate-dead-branches'
+# '--merge-return'
+# '--eliminate-dead-branches'
+# '--merge-blocks'
+# '--eliminate-local-single-block'
+# '--eliminate-dead-branches'
+# '--merge-return'
+# '--ccp'
+# '--scalar-replacement=100'
+# '--eliminate-local-single-block'
+# '--simplify-instructions'
+# '--redundancy-elimination'
+# '--eliminate-local-multi-store'
