Andreas Klebinger pushed to branch wip/andreask/9.10.4-batch1 at Glasgow Haskell Compiler / GHC Commits: 580bc78d by Ben Gamari at 2026-05-25T16:17:47+02:00 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. (cherry picked from commit 39eaaaba5356e3fc9218d8e27375d6de24778cbc) - - - - - d9e27e4d by Rodrigo Mesquita at 2026-05-25T16:17:54+02:00 Move code-gen aux symbols from ghc-internal to rts These symbols were all previously defined in ghc-internal and made the dependency structure awkward, where the rts may refer to some of these symbols and had to work around that circular dependency the way described in #26166. Moreover, the code generator will produce code that uses these symbols! Therefore, they should be available in the rts: PRINCIPLE: If the code generator may produce code which uses this symbol, then it should be defined in the rts rather than, say, ghc-internal. That said, the main motivation is towards fixing #26166. Towards #26166.

One source of such references in the RTS is the many symbols referenced in ghc-internal. To mitigate #26166, we make these references dynamic, as described in Note [RTS/ghc-internal interface].
