The parser generates a tree of the algebraic expression, the tree is representative of the evaluation order of the expression, earlier evals lower in the tree, the node at the top is the last evaluated. Then walk the tree from the bottom up to generate code.

I think code to do this (efficient compiler code generation) has been done like a gazillion-billion times since 1960.
