Data spaces in iteration spaces

[Aaron3154518]

Iteration spaces should only hold constants and iterators, neither of which require "$". Sometimes, constants are also data spaces, one case being they are passed in as parameters (Spline_length for example). These constants still need to be recognized as data spaces, specifically when generating phi nodes. Currently, we do that by putting "$" around them, which iegenlib does not like. We then strip those "$" before calling any Set functions. This is a poor solution.

Issues:

• [ ] We sometimes have if constraints which are not constants/iterators. We still need to add them to the iteration space so they can be recognized by phi nodes.
• [ ] Fix "$"
  • [ ] 1) Recognize all constants as data spaces. Thus we don't need "$" because as long as the variable isn't an iterator, it is guaranteed to be a data space. (This might already be the case - check with Dr. Olschanowsky)
  • [ ] 2) insert solution here

Temporary fix for find segment if statement is not having the [i] and [i+1] for x_vals Source code : if($x$ >= $x_vals$[i] && $x$ <= $x_vals$[i+1]) $prev$ = i; Current Fix(in constraints) : {[i]: i>=0 && i<$length$-1 && $x$ >= $x_vals$ && $x$ <= $x_vals$}
