Zubin pushed to branch wip/9.10.3-backports at Glasgow Haskell Compiler / GHC Commits: 1e683e75 by Jens Petersen at 2025-07-24T19:43:04+05:30 9.10 hadrian can build with Cabal-3.12.1 fixes #25605 (cherry picked from commit 07f17b6ed1bb0ba7134ee8dfd992036e97552c94) - - - - - ed36fab9 by sheaf at 2025-07-24T19:43:04+05:30 Don't cache solved [W] HasCallStack constraints This commit ensures we do not add solved Wanted constraints that mention HasCallStack or HasExceptionContext constraints to the set of solved Wanted dictionary constraints: caching them is invalid, because re-using such cached dictionaries means using an old call-stack instead of constructing a new one, as was reported in #25529. Fixes #25529. (cherry picked from commit 256ac29c8df4f17a1d50ea243408d506ebf395d6) - - - - - 2d56479d by Zubin Duggal at 2025-07-24T19:43:04+05:30 In commit "Don't cache solved [W] HasCallStack constraints" (256ac29c8df4f17a1d50ea243408d506ebf395d6), we attempt to use `tryM` to avoid errors when looking up certain known-key names like CallStack while compiling ghc-prim and ghc-internal. Unfortunately, `tryM` doesn't catch module lookup errors. This manifests as a failure to build ghc-prim in `--make` mode on the GHC 9.10 branch. Instead, we explicitly avoid doing lookups when we are compiling ghc-prim or ghc-internal instead of relying on catching the exception. - - - - - c9ed6c63 by Zubin Duggal at 2025-07-24T19:43:04+05:30 Consider `PromotedDataCon` in `tyConStupidTheta` Haddock checks data declarations for the stupid theta so as not to pretty-print them as empty contexts. Type data declarations end up as `PromotedDataCon`s by the time Haddock performs this check, causing a panic. This commit extends `tyConStupidTheta` so that it returns an empty list for `PromotedDataCon`s. This decision was guided by the fact that type data declarations never have data type contexts (see (R1) in Note [Type data declarations]). Fixes #25739.

We also need to look in the modules on which they depend, including those outside of this package. Fixes #25147. Fixes #26079.
