Zubin pushed to branch wip/9.10.3-backports at Glasgow Haskell Compiler / GHC Commits: e61cf95b by Jens Petersen at 2025-07-24T19:58:47+05:30 9.10 hadrian can build with Cabal-3.12.1 fixes #25605 (cherry picked from commit 07f17b6ed1bb0ba7134ee8dfd992036e97552c94) - - - - - 70aaec05 by sheaf at 2025-07-24T19:58:47+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) - - - - - 7ad8db1e by Zubin Duggal at 2025-07-24T19:58:47+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. - - - - - b7196825 by Zubin Duggal at 2025-07-24T19:58:47+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.

Any consecutive lines with birdtracks will only have initial whitespace stripped up to the column of the first line.

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