[Git][ghc/ghc][wip/romes/26166-move-prims] Move code-gen aux symbols from ghc-internal to rts
Rodrigo Mesquita pushed to branch wip/romes/26166-move-prims at Glasgow Haskell Compiler / GHC Commits: e9d3d440 by Rodrigo Mesquita at 2025-10-10T12:07:53+01:00 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.
