Torsten Schmits pushed to branch wip/torsten.schmits/unit-index-debug at Glasgow Haskell Compiler / GHC Commits: 43fca822 by Matthew Pickering at 2025-12-04T11:57:58+01:00 Don't call implicitRequirementsShallow - - - - - cdedac3a by Ben Gamari at 2025-12-04T11:57:58+01:00 compiler: Fix CPP guards around ghc_unique_counter64 The `ghc_unique_counter64` symbol was introduced in the RTS in the 64-bit unique refactor (!10568) which has been backported to %9.6.7 and %9.8.4. Update the CPP to reflect this.
