Description
Function evaluateFunctions_updateStatement, which is called from evaluateConstantFunctionCallExp, takes very long for some models with many nested functions, because of a very deep recursion level.
The module is called to evaluate parameter function-bindings to a constant value, if possible. In most cases the module spots at the end that it is not possible, so all the effort is for nothing.
Because of that, the module only should be called if the function can be definetly evaluated, i.e. if the function arguments are already evaluated constants (final parameters and parameters dependent on them).
Note:
See TracTickets
for help on using tickets.
In OMCompiler/295b0a4 a flag is added to only evaluate parameter function-bindings with constant arguments. Default: --evalConstArgsOnly=true
