Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: f7adfed2 by ARATA Mizuki at 2025-10-08T08:37:24-04:00 T22033 is only relevant if the word size is 64-bit Fixes #25497 - - - - - ff1650c9 by Ben Gamari at 2025-10-08T08:38:07-04:00 rts/posix: Enforce iteration limit on heap reservation logic Previously we could loop indefinitely when attempting to get an address space reservation for our heap. Limit the logic to 8 iterations to ensure we instead issue a reasonable error message. Addresses #26151. - - - - - 01844557 by Ben Gamari at 2025-10-08T08:38:07-04:00 rts/posix: Hold on to low reservations when reserving heap Previously when the OS gave us an address space reservation in low memory we would immediately release it and try again. However, on some platforms this meant that we would get the same allocation again in the next iteration (since mmap's `hint` argument is just that, a hint). Instead we now hold on to low reservations until we have found a suitable heap reservation. Fixes #26151. - - - - - b2c8d052 by Sven Tennie at 2025-10-08T08:38:47-04:00 Build terminfo only in upper stages in cross-builds (#26288) Currently, there's no way to provide library paths for [n]curses for both - build and target - in cross-builds. As stage0 is only used to build upper stages, it should be fine to build terminfo only for them. This re-enables building cross-compilers with terminfo. - - - - - c58f9a61 by Julian Ospald at 2025-10-08T08:39:36-04:00 ghc-toolchain: Drop `ld.gold` from merge object command It's deprecated.

We leverage these changes to remove the ad-hoc treatment of linearity of data constructors with 'dataConDisplayType' and 'dataConNonLinearType'. This is now handled by the machinery of 'pprWithInvisibleBits'. Fixes #26335 #26340 - - - - - d1316ecd by sheaf at 2025-10-08T09:12:53-04:00 Store SDoc context in SourceError This commits modifies the SourceError datatype which is used for throwing and then reporting exceptions by storing all the info we need to be able to print the SDoc, including whether we should print with explicit kinds, explicit runtime-reps, etc. This is done using the new datatype: data SourceErrorContext = SEC !DiagOpts !(DiagnosticOpts GhcMessage) Now, when we come to report an error (by handling the exception), we have access to the full context we need.
