m2isar.metamodel.utils.expr_simplifier

A transformation module for simplifying M2-ISA-R behavior expressions. The following simplifications are done:

  • Resolvable m2isar.metamodel.arch.Parameter s are replaced by m2isar.metamodel.arch.Literal s representing their value

  • Fully resolvable arithmetic operations are carried out and their results represented as a matching m2isar.metamodel.arch.Literal

  • Conditions and loops with fully resolvable conditions are either discarded entirely or transformed into code blocks without any conditions

  • Ternaries with fully resolvable conditions are transformed into only the matching part

  • Type conversions of m2isar.metamodel.arch.Literal s apply the desired type directly to the Literal and discard the type conversion
