- GC segfault with devel2 compiler on T16525a
- Sub-word right-arithmetic-shifts appear to be wrong on x86
- Regression `refineFromInScope` caused by "Get the in-scope set right during RULE matching"
- Mysterious issue with bytestring "LazyWord8.fromString literal" test
- ghc-bignum version is not bumped
- regression in GHC 9.0.1: panic converting to STG
- runhaskell is missing on Windows
- fromIntegral (2^64 :: Integer) == (0 :: Natural)
- GHC-9.0.1 doesn't find imported main:
- GHC 9.0 regression: plots-0.1.1.2 fails to build due to ambiguous type variable
- Cannot build threaded Windows DLL with 9.0.1 and 9.2 RC1
- Unicode strings are mangled in GHC 9.0.1
- Missing ghc-9.0.1.exe executable in bindist
- Win32 Backports to release branches
- Runtime Perf: Allocations increased by 15x in GHC-9 vs GHC-8
- Building GHC fails for x86 with BMI2: The code generator tries to produce illegal instructions which cannot assemble (the PDEP & PEXT instructions can't take 16bit operands).
- ghci readily resets package state
- No instance for (Eq BigNat)
- text benchmarks are wildly slower in 9.0.1
- Simplifier ticks exhausted on mapM/traverse
- Concerning TSAN failures in STM
- Hadrian build of rts is broken due to missing assembler file(s) compilation.
- CApiFFI generates bad prototypes for pointers of `Foreign.C` types
- GHC 8.10.x RebindableSyntax and HPC produce unexpected 'Impossible case alternative' errors (and occasionally segfaults)
- Regression in 9.0.1: -Werror=unused-packages suppresses real compilation error
- GHC 9.0.1 panic with linear types + GADTs
- GHCi prompt alignment on multiline input
- Wrongfully assumes user-defined Typeable instance when using QuantifiedConstraints
- Update docs for change in parsing behaviour of infix operators like `@` in GHC 9
- __builtin_popcountll causes linking issue on Windows
- Data.Text.Show.singleton fails to CPR in GHC 9.0.1
- Benchmarks of `random` regressed in runtime from 8.10 to 9.0
- Warning mentions GHC-8.12 in GHC-9.0
- Wrong and redudant `incomplete-patterns` warnings
- Levity monomorphic instantiation of unsafeCoerce# is rejected as being levity polymorphic in 9.0+
- Missing documentation on -funfolding-keeness-factor deprecation
- Type literals in Reflection of type constructor kinds leads to SafeHaskell violation
- Windows ghc-8.10.3 segfaults on TH-heavy code in multithreaded setting because of (I believe) 92c9bed7beabb6278d6bc3b228f3aa55e423e192
- memo002 fails when built with optimisation
- Fix issues with NamedPipes and blocking calls in non-threaded rts
- Backport adjustor rework to 9.0.2
- Support for Apple ARM hardware
- Release tracking ticket for GHC 9.0.2
