#10506: SourceNotes are not applied to all identifiers -------------------------------------+------------------------------------- Reporter: gridaphobe | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.2 Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by scpmw): I didn't actually change how `TickForCoverage` behaves, so these design decisions actually go back to HPC. Changing it would be quite easy - probably just replacing a few `addTickLHsExprNever` in `addTickHsExpr` by `addTickLHsExpr`. On the other hand I'm not quite sure we want that. The original reason was probably that it leads to rather silly stacks of ticks on functions that are applied to many arguments. Plus both source notes and HPC ticks would instantly float upwards, which means that we are not actually gaining any information. Source notes get merged eventually, but for HPC it certainly would make a performance difference. Do you positively need every single expression annotated? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10506#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
