#13529: eventlog to report more information about stopping threads because of FFI calls -------------------------------------+------------------------------------- Reporter: varosi | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Profiling | Version: 8.0.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: x86_64 | (amd64) Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): How do you propose we would identify which foreign function is being called? I can think of a few ways, * Have the compiler produce a string which is passed to the RTS when generating code for safe foreign calls * Use the symbol table lookup of the callee's address * Use DWARF information of the callee's address All of these have their costs and I do wonder whether this sort of instrumentation might not be better left to the user to implement themselves with, e.g. `traceEvent`, if they need it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13529#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
