// to ELF object, source file and function. We use the first cost
// seen for a function to bind an ELF object and source file to that
// function. Callgrind always prints the cost of the instruction at
// function entry first, so there, this strategy works.
// But such an order is not enforced by the format. If the cost of
// an inlined function from another source file would be printed first,
// the attribution would go wrong. The format also allows cost of
// the same function to be spreaded over the dump. With wrong
// attributions, it can happen that cost of the same function is
// interpreted as being from distinct functions.
// For a correct solution, the format needs to be more expressive,
// or the ordering of costs specified.
// Previously, the file name was left out from the key.
