Simon Peyton Jones pushed to branch wip/T23162-spj at Glasgow Haskell Compiler / GHC Commits: ba210d98 by Simon Peyton Jones at 2025-09-08T16:26:36+01:00 Report solid equality errors before custom errors This MR fixes #26255 by * Reporting solid equality errors like Int ~ Bool before "custom type errors". See comments in `report1` in `reportWanteds` * Suppressing errors that arise from superclasses of Wanteds. See (SCE1) in Note [Suppressing confusing errors] More details in #26255. - - - - - b6249140 by Simon Peyton Jones at 2025-09-10T10:42:38-04:00 Fix a scoping error in Specialise This small patch fixes #26329, which triggered a scoping error. Test is in T21391, with -fpolymorphic-specialisation enabled - - - - - 45305ab8 by sheaf at 2025-09-10T10:43:29-04:00 Make rationalTo{Float,Double} inline in phase 0 We hold off on inlining these until phase 0 to allow constant-folding rules to fire. However, once we get to phase 0, we should inline them, e.g. to expose unboxing opportunities. See CLC proposal #356. - - - - - 0959d4bc by Andreas Klebinger at 2025-09-10T10:44:12-04:00 Add regression test for #26056 - - - - - dc79593d by sheaf at 2025-09-10T10:45:01-04:00 Deep subsumption: unify mults without tcEqMult As seen in #26332, we may well end up with a non-reflexive multiplicity coercion when doing deep subsumption. We should do the same thing that we do without deep subsumption: unify the multiplicities normally, without requiring that the coercion is reflexive (which is what 'tcEqMult' was doing).

This significantly helps when deubbging relocation issues reported by users. - - - - - 4e67855b by Moritz Angermann at 2025-09-10T10:47:54-04:00 test.mk expect GhcLeadingUnderscore, not LeadingUnderscore (in line with the other Ghc prefixed variables. - - - - - c1cdd265 by Moritz Angermann at 2025-09-10T10:48:35-04:00 testsuite: Fix broken exec_signals_child.c There is no signal 0.
