#14375: Implement with# primop -------------------------------------+------------------------------------- Reporter: simonpj | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: JoinPoints Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #14346 | Differential Rev(s): ​Phab:D4110 Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Like I say, I'm thinking of this as STG only; an intermediate on the way to codegen. Yes there are still invariants. To be a bit more precise `maskAsyncExceptions# j s`, `j` must be an arity-1 join point. Always. But I am only thinking aloud here. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14375#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
