.prof files contain a cost centre number, which I assume is cc_key from
CostCentre.lhs. It would be immensely helpful if the compiler creates a
simpe table. This way, one could look up the number in .prof, check the
table and the exact source location. It would also help with #7105, I
think.
Suggestion for the format:
{{{
no. file begin end
1 main.hs 127:7 128:14
}}}
Meaning: Cost centre 1 is in file main.hs, begins at line 127, character 7
and ends at line 128, character 14.
If somebody points me in the right direction, and the whole thing is not
too complicated, I can try my hand at implementing it myself.
