#12022: unsafeShiftL and unsafeShiftR are not marked as INLINE -------------------------------------+------------------------------------- Reporter: Rufflewind | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 7.10.3 Resolution: | Keywords: performance, | inline, bits Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by dfeuer): More importantly, the note is nonsense. Things not marked `INLINE` or (more strongly) `INLINE CONLIKE` sometimes won't be inlined even though they can be, once the code around them gets complicated enough. An operation like an unsafe shift, mask, etc., that's literally cheaper than a function call should *always* be inlined, unless I'm extremely confused. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12022#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
