Why not use
objdump --disassemble-all my_program.exe | grep SparseSolver
then 'addr2line'? That way you don't require constructing the input data
that is required to exercise all the call paths, nor must you run the program
30 times slower than normal. Of course, any method is unlikely to find
all the calls that have been inlined by the compiler or specialized+merged
using constant propagation and link-time optimization.
