#14509: Consider adding new stg_ap_* functions -------------------------------------+------------------------------------- Reporter: dobenour | Owner: (none) Type: task | Status: new Priority: normal | Milestone: 8.4.1 Component: Runtime | Version: 8.2.1 System | Keywords: | 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: -------------------------------------+------------------------------------- Currently, the RTS has a fixed set of `stg_ap_*` functions. There are two problems with this: 1. All programs pay for these functions, even programs that don’t use them. Furthermore, it is not possible for new ones to be generated by GHC for certain cases. 2. The set included in the RTS may not be optimal. (1) is a lot of work, but dealing with (2) should be “just” a matter of hunting down which functions would be useful. I would start with ByteString, Text, and other highly optimized libraries, some of which (such as ByteString) are very widely used. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14509 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
