| // DeferGlobalInitializers is an AST traverser that moves global initializers into a function, and |
| // adds a function call to that function in the beginning of main(). |
| // This enables initialization of globals with uniforms or non-constant globals, as allowed by |
| // the WebGL spec. Some initializers referencing non-constants may need to be unfolded into if |
| // statements in HLSL - this kind of steps should be done after DeferGlobalInitializers is run. |
