#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 simonpj): This tick stuff is clearly interesting and useful, but it is serving several masters, which are expressed by `CoreSyn.Tickish`: * `HpcTick`: HPC code coverage * `ProfNote`: cost-centre profiling * `Breakpoint`: breakpoint debugging * `SourceNote`: do not get in the way of optimisation, but help with debugging via DWARF. They differ in the extent to which they interfere with optimisation. You probably want either `SourceNote` or `HpcTick` here; but I'm not sure which. It depends on the semantics you expect during optimisation. I suspect you want `SourceNote`. I hope you don't need a fifth one!
