Today's HEAD produced 49 unexpected failures, most of which are caused by
trivia.
- tcrun006 and tcrun029 use datatype contexts which were removed from HEAD
(7 ways each), can be fixed by adding a language pragma
(cf. also http://hackage.haskell.org/trac/ghc/ticket/5229)
- ghcpk01.stdout hasn't yet been updated to include the new trusted field
- ffi005 fails to compile (7 ways) due to an ambiguous occurrence of
unsafePerformIO (Foreign and System.IO.Unsafe)
- cg005 and T4059 have unexpected stderr due to a warning about
unsafePerformIO going to be removed from Foreign
- T4437 fails to compile due to a type change:
T4437.hs:9:39:
Couldn't match expected type `(String,
CmdLineParser.FlagSafety,
ExtensionFlag,
DynFlags.TurnOnFlag - DynFlags.DynP
())'
with actual type `(t0, t1, t2)'
In the pattern: (ext, _, _)
In a stmt of a list comprehension: (ext, _, _) - xFlags
In the expression: [ext | (ext, _, _) - xFlags]
Those are easily fixed by the attached patches (but some may need a more
principled fix).
Further, 17 unexpected failures are due to hpc output being formatted
differently from the expectation (5x hpc_fork, 6x hpc001, 6x tough).
Two unexpected failures (T4809, cgrun068) are due to mtl not being built
the dyn way.
The remaining 5 are
- T4801 (allocating too little because there are fewer Generic instances
for tuples)
- dph-diophantine-opt (3 ways)
- dph-words-opt
On my 32-bit box, also T3294 unexpectedly fails since about a week ago due
to too little allocation (a bit below 690M, minimum allowed 800M).
If that's reproducible and not known to be temporary, the bounds should be
adjusted.
Cheers,
Daniel
