Issue with parameter bindings involving Complex equations in the NF

[Francesco Casella]

Please consider the follwing test model

model TestComplexParameter
  import CM = Modelica.ComplexMath;
  parameter Real v_abs_start = 2, v_phase_start = 0.5;
  parameter Modelica.SIunits.ComplexVoltage v_start = CM.fromPolar(v_abs_start, v_phase_start);
  Modelica.SIunits.ComplexVoltage v(re(start=v_start.re), im(start=v_start.im));
equation
  CM.'abs'(v) = 1;
  CM.arg(v) = 0.5;
end TestComplexParameter;

When building the model with the NF, the generated TestComplex_06inz.c C-code contains:

/*
 equation index: 1
 type: ALGORITHM
 
   v_start := Complex(v_abs_start * cos(v_phase_start), v_abs_start * sin(v_phase_start));
 */
void TestComplex_eqFunction_1(DATA *data, threadData_t *threadData)
{
  TRACE_PUSH
  const int equationIndexes[2] = {1,1};
  Complex tmp0;
  Modelica_SIunits_ComplexVoltage tmp1;
  tmp0._re = (data->simulationInfo->realParameter[0]) * (cos(data->simulationInfo->realParameter[1]));
  tmp0._im = (data->simulationInfo->realParameter[0]) * (sin(data->simulationInfo->realParameter[1]));
  tmp1 = tmp0;
  data->simulationInfo->realParameter[3] = tmp1._re;
  data->simulationInfo->realParameter[2] = tmp1._im;
  TRACE_POP
}

which breaks the compiler because Modelica_SIunits_ComplexVoltage is undefined.

I understand binding equations for Complex parameters are now moved to the initial equations. For some reason, this one is not inlined correctly, as it is instead the case for regular binding equations, such as in

model TestComplexVariable
  import CM = Modelica.ComplexMath;
  Modelica.SIunits.ComplexVoltage v = CM.fromPolar(time, sin(time));
end TestComplexVariable;

Perhaps the Inline annotation of the fromPolar function is lost on these added initial equations?
