| 6 | // DeferGlobalInitializers is an AST traverser that moves global initializers into a function, and |
| 7 | // adds a function call to that function in the beginning of main(). |
| 8 | // This enables initialization of globals with uniforms or non-constant globals, as allowed by |
| 9 | // the WebGL spec. Some initializers referencing non-constants may need to be unfolded into if |
| 10 | // statements in HLSL - this kind of steps should be done after DeferGlobalInitializers is run. |
