# This tests we inline functions correctly. Chaining the functions helps
# us reach the GLSL IR -> NIR code with some functions intact when the
# conservative optimise flag is set in Mesa. This allows us to test the
# GLSL IR -> NIR conversion code for functions and the NIR function inlining
# code.
