#8256: adding locality levels to prefetch# and friends -------------------------------------+------------------------------------ Reporter: carter | Owner: carter Type: task | Status: closed Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.7 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: #8252 ,#8107 -------------------------------------+------------------------------------ Comment (by simonpj): Great stuff. Questions about the patch: * The primops are all marked `can_fail = True`. Could there be some words of documentation to explain why? I recall scratching my head over the can-fai-ness of primops before, so documenting the reasoning is a Good Thing. * Would it be possible to include in the Haddock comments in `primops.txt.pp` a URL where one can read more about the prefetch instructions and "locality levels"? I know that URLs go out of date, but a start would be useful. Perhaps with some keywords from that web page that might be a starting point for a subsequent search if the URL went stale.
