Function eval_elementwise

src/ir/compiler.rs:42–48

Evaluate an elementwise expression over input arguments, producing a new Buffer. Compilation results are cached by expression structure via [`CompileCache`]. Expressions without `Select` use the flat interpreter. Expressions with `Select` use a lazy tree evaluator so dead branches are not evaluated.
