8 * Defines the lowering pass that insert mutex allocation code & locks
9 * for the atomic nodes that require mutex locks. It also checks whether
10 * the atomic operation is valid. It rejects algorithms that have indexing
11 * on left-hand-side which references the buffer itself, e.g.
12 * f(clamp(f(r), 0, 100)) = f(r) + 1
13 * If the SplitTuple pass does not lift out the Provide value as a let
14 * expression. This is confirmed by checking whether the Provide nodes
15 * inside an Atomic node have let binding values accessing the buffers
16 * inside the atomic node.
17 * Finally, it lifts the store indexing expressions inside the atomic node
18 * outside of the atomic to avoid side-effects inside those expressions
19 * being evaluated twice. */
