#15086: hT profiling option -------------------------------------+------------------------------------- Reporter: crockeea | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.4.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Documentation | Unknown/Multiple bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): I'm confused; `+RTS -hT` works for me under both GHC 8.4.2 and 8.2.2 and indeed produces a `.hp` file after the program finishes. Are you perhaps building with profiling enabled? Do note that `-hT` is only available when *not* built with profiling (although admittedly it's not clear to me why this must be the case). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15086#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

A note in the help message is good, but the help message and docs need to be updated to indicate that profiling must be *off* for the option to be enabled. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15086#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
