Marge Bot pushed to branch wip/marge_bot_batch_merge_job at Glasgow Haskell Compiler / GHC Commits: a7f15858 by sheaf at 2025-09-24T09:49:53-04:00 User's guide: clarify optimisation of INLINABLE unfoldings This updates the user's guide section on INLINABLE pragmas to explain how the unfoldings of inlineable functions are optimised. The user's guide incorrectly stated that the RHS was not optimised at all, but this is not true. Instead, GHC is careful about phase control to optmise the RHS while retaining the guarantee that GHC behaves as if the original RHS had been written. - - - - - 495886d9 by Rodrigo Mesquita at 2025-09-24T09:50:35-04:00 cleanup: Delete historical artifact of COMPILING_WINDOWS_DLL Namely, drop the obsolete - DLL_IMPORT_RTS - DLL_IMPORT_DATA_VAR - DLL_IMPORT_DATA_VARNAME - DLL_IMPORT_DATA_REF These macros were not doing anything and placed inconsistently Looking at the git logs reveal these macros were used to support dynamic libraries on Win32, a feature that was dropped in b8cfa8f741729ef123569fb321c4b2ab4a1a941c This allows us to get rid of the rts/DLL.h file too. - - - - - 23fa7357 by Sylvain Henry at 2025-09-24T12:26:27-04:00 Allow disabling builtin rules (#20298) Add a way to disable built-in rules programmatically and with a debug flag. I also took the opportunity to add a debug flag to disable bignum rules, which was only possible programmatically (e.g. in a plugin). - - - - - 807f5c86 by Rodrigo Mesquita at 2025-09-24T12:26:28-04:00 Don't use build CFLAGS and friends as target settings In the GHC in tree configure, `CFLAGS`, `CXXFLAGS`, and similar tool configuration flags apply to the BUILD phase of the compiler, i.e. to the tools run to compile GHC itself. Notably, they should /not/ be carried over to the Target settings, i.e. these flags should /not/ apply to the tool which GHC invokes at runtime.
