Default action for leaf processing.
Default action for leaf processing. Can be overridden to call ICE (to ensure that all processing is implemented by pass).

Return true if given expression is "complex".
Return true if given expression is "complex".
We are a bit pessimistic for simplicity. For example a[2*2] or a[j*2] wouldn't need extraction, but a[j*j] would; we extract all three cases.

All raw variables must be eliminated before leaving the front-end.
Array index expression extraction pass.
Extracts array index expressions that are considered "complex" into separate variables. For example:
x = a[(i*i)/2];
becomes
idx_3 = (i*i)/2; x = a[idx_3];
The purpose of this transformation is to aid code generation using PPCG. PPCG currently cannot handle the former case, whereas it can handle the latter.
