Description
Problem*
Resolves
Summary*
Draft until #2376 is merged.
This PR improves our handling of values which can be computed at compile-time. Instead of checking that
lhsandrhsare constant and then adding them together to produce a constant result, we addlhsandrhstogether and check that the result is constant. This allows us to pick up any cases where non-constant terms in the inputs cancel out.I've also implemented
AcirVarData::from<Expression>()which will produce the simplest variant ofAcirVarDataso it's easier to perform optimisations later.Documentation
This PR requires documentation updates when merged.
