@return last element

Replaces all occurrences of source with target in the uses list of the instruction

Does this node contain all constants? Ignores in(0), as is usually control. In an input is not a constant, we add dep as a dependency to it because

Routes evaluation of {@code expr} to caller-supplied true and false targets. Logical operators are expanded recursively to preserve short-circuit eval

Create a new variable name in the current scope

Find the first matching element using ==, or -1 if none. Note that most del calls shuffle the list, so the first element might be random. @param e

Utility to locate all the basic blocks, order does not matter.

Compute greatest lower bound in the lattice. If values are in memory, ints and floats cannot widen.

Slow, linear-time, element insertion. Preserves order. @param i where to insert @return element inserted
