The insertion sort code is taken from the Mälardalen WCET benchmark suite, but altered to move the inner loop into its own function for compatibility with the SEL4 tools.

The C parsing and graph export code in Insertsort.thy is based on the examples in the graph-refine repository and the SEL4 code. The target.py driver is based on the graph-refine ones, but has a little extra code added to ignore the cycle counter variable in loops.
