Description
Wonder if is possible to put the information set by initialAnalyticJacobian into an XML file (or binary one) and load it on startup.
The function generated for model:
Modelica.Electrical.Spice3.Examples.Spice3BenchmarkFourBitBinaryAdder
is HUGE (takes 90% of a 63 Mb C file). GCC uses 8Gb to compile it.
I've split that function down in r17639 but GCC memory consumption went down only by about 2Gb.

This ticket was not closed for 1.9.1, which has now been released. It was batch modified for milestone 1.9.2 (but maybe an empty milestone was more appropriate; feel free to change it).

This has been fixed in the meanwhile, the biggest c file is now *_08bnd.c with around 10MB.

Instead of tackling the jacobian, I'd suggest that we work on #2576.
If that is fixed, the huge Jacobian should disappear as soon as we use Volker's resolveLoop module.
