Ben Gamari pushed to branch wip/T26166-1 at Glasgow Haskell Compiler / GHC Commits: 757b4319 by Ben Gamari at 2025-09-29T15:27:57-04:00 rts: Dynamically initialize built-in closures To resolve #26166 we need to eliminate references to undefined symbols in the runtime system. One such source of these is the runtime's static references to `I#` and `C#` due the `stg_INTLIKE` and `stg_CHARLIKE` arrays. To avoid this we make these dynamic, initializing them during RTS start-up. - - - - - 7 changed files: - + rts/BuiltinClosures.c - + rts/BuiltinClosures.h - rts/RtsStartup.c - rts/StgMiscClosures.cmm -
