#13143: NOINLINE and worker/wrapper -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: bug | Status: closed Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 8.0.1 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): D3046 Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj):
I guess the test suite did not come up with anything, but does this interfere with rules? A rule might mention the NOINLINE thing, but aftetr W/W, the worker remains, and a rule will no longer fire.
That's a worry for all functions; but the wrapper always get an inline activation that allows it to inline only in the last phase. See `Note [Wrapper activation]` in `WorkWrap`. What you say has merit; but it was bad bad bad before we made this change. If there's actually a problem with this new story, let's see it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13143#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
