J'ai rajouté quelques fix pour que les tests passent mieux - notamment, j'ai corrigé la représentation des binops au niveau compilateur pour limiter la quantité de parentheses, car dans l'état on dépassait les 256 parentheses (ce qui lève un gros flag au moment de la compilation). |

This PR adds a new
--no-local-varoption that forces mlang not to define local vars when calculating expressions.Expressions were compiled as sets of simple binary operations of the form
inti = intj || int k;. While this is memory efficient, I believe having the whole expression could lead to some optimizations.C compilers can optimize code with smarter heuristics. For example, when checking the definition of a given variable, the current code calculates all the possible branches while some of them could be simplified quickly (if
DC_[A] = 1, thenDC_[A] || DC_[B] || DC_[C] || DC_[D]can be evaluated to1directly, whileint0 = DC_[A] || DC_[B]; int1 = int0 || DC_[C]; int0 = int1 || DC_[D];requires to calculate everything.)We could simplify boolean expressions with some basic boolean algebra.
Ideally, the
--no-local-varoption is meant to be temporary. Either the optimization makes the code more efficient and the option becomes the default behavior, or this PR will document why mlang behaves like this.
