- Values from constant variables are folded in when it helps, e.g.:
const bool SHINY = true;
const float SHININESS = 2;
if (!SHINY) { // <-- optimizes directly to `false`
param = -SHININESS; // <-- optimizes to `-2`
- Doubled-up logical-not and negation are stripped:
y = -(-x); // <-- optimizes to `y = x;`
b = !!a; // <-- optimizes to `b = a;`
Removal of doubled-up negation and logical-not was actually never
implemented in the constant-propagation phase; I just noticed it while
I was here and thinking about it.

The test has been split into an ES2 version and ES3 version; the ES2
side omits unsupported integer ops like << >> & | ^ %.
