#11772: GHC.CString.unpackCStringUtf8# is inlineable -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: 8.0.1 Component: Core | Version: 7.10.3 Libraries | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- While looking through the logs of a build of a project I have lying around with a GHC 8.0 snapshot, I noticed that there may still be some fragile rules in the `text` package (see #11528 for a previous issue). The problem is that `GHC.CString.unpackCStringUtf8#` may be inlined, which may preempt the `TEXT literal UTF8` rule in `Data.Text.Show`. `unpackCStringUtf8#` doesn't seem like a terribly great candidate for inlining as it produces a list, {{{#!hs unpackCStringUtf8# :: Addr# -> [Char] }}} Moreover, the other functions in this module along these lines (e.g. `unpackCString#` are marked `NOINLINE`. Perhaps this should have a `NOINLINE` pragma as well? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11772 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
