#14090: Static pointers are not being registered under certain conditions -------------------------------------+------------------------------------- Reporter: mnislaih | Owner: (none) Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3843 Wiki Page: | -------------------------------------+------------------------------------- Comment (by facundo.dominguez): I know of three ways to accomplish it in ghc-8.2.1 without the SPT. 1. Use {{{addForeignFile}}} and {{{addTopDecls}}} to make the bytecode available via a foreign import. https://gist.github.com/facundominguez/82f6768e1f4d5fbfecf008115226a484 2. Use {{{addForeignFile}}} to insert a constructor function in the module to initialize a global bytecode table when the module is loaded. https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index- constructor-function-attribute 3. Like (2), but instead of using {{{addForeignFile}}} to insert the constructor function, use a GHC plugin to inject it. This is the approach that inline-java uses in the latest version in the repo. https://github.com/tweag/inline- java/blob/6c4aa0e94a4952ce91a498d2b64198a5e158ee57/src/Language/Java/Inline/Plugin.hs#L73 (3) works with 8.0.2 as well. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14090#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
