- Attach a SrcSpan to every CostCentre. This had the side effect that CostCentres that used to be merged because they had the same name are now considered distinct; so I had to add a Unique to CostCentre to give them distinct object-code symbols. - New flag: -fprof-auto-calls. This flag adds an automatic SCC to every call site (application, to be precise). This is typically more useful for call stacks than annotating whole functions. Various tidy-ups at the same time: removed unused NoCostCentre constructor, and refactored a bit in Coverage.lhs. The call stack we get from traceStack now looks like this: Stack trace: Main.CAF (<entire-module>) Main.main.xs (callstack002.hs:18:12-24) Main.map (callstack002.hs:13:12-16) Main.map.go (callstack002.hs:15:21-34) Main.map.go (callstack002.hs:15:21-23) Main.f (callstack002.hs:10:7-43)
