#12417: API annotations for unboxed sums needs reworking -------------------------------------+------------------------------------- Reporter: osa1 | Owner: alanz Type: bug | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 8.1 (Parser) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect API | Unknown/Multiple annotation | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by alanz): An unboxed tuple such as {{{#!hs (# | b | | | | | #) }}} Ends up in the parser via `tup_exprs` as {{{#!hs Sum 2 7 lexp }}} where `lexp` is a `LHsExpr` From an annotation perspective, the 5 `AnnVbar`s after the `b` are attached to `lexp`, but currently the leading `AnnVbar`s do not have a home. They need to be attached to the parent tuple expression. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12417#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
