backenddaeinfo statistics counts wrong no. of single equations

[Patrick Täuber]

Example: testsuite/simulation/modelica/tearing/Tearing2-1.mos

After Tearing:
StrongComponents
========================================
{9:6}
{{{8:4}, {4:7}, {2:8}}
,{3:3} Size: 1 linear
{5:2}
{1:9}
{6:1}
{7:5}

But backenddaeinfo statistics counts:
Single Equations: 6
torn linear Equationsystems: 1 {1 3}

Apparently the no. of torn systems is not subtracted from the no. of single equations.

I agree. Various strong component types are collapsed for this dump. This is a bit confusing and could be done better. We distinguish between

• SINGLEEQUATION
• EQUATIONSYSTEM
• MIXEDEQUATIONSYSTEM
• SINGLEARRAY
• SINGLEALGORITHM
• SINGLECOMPLEXEQUATION
• SINGLEWHENEQUATION
• SINGLEIFEQUATION
• TORNSYSTEM

in the corresponding Backend uniontype.
It would be better if the dump lists all of these types individually.

I gues you can fix it by your own. It is good for practising ;-)
Also I have added Jens, because I guess he introduced that dump.

• feel free to change it. Primarily it was informative for compiler developers. Now since it is also used in OMEdit it could be more informative for modellers

[Lennart Ochel]

Well, I agree. This is actually more an enhancement than a defect. Anyway, it might be also for developers interesting/important whether a strong component is handled as single equation or torn system.
