20110629: after new level representation and optimised positivity check
3
(used interface file for monad example)
5
20110701: actually type checking the monad example
7
20110706: (15:00) better precision in ArgsCmp constraints (avoiding rechecking
10
20110822: (13:30) switched compareArgs to compareElim (without getting rid of
11
projection arguments). 1 second faster on monad and 1.5 seconds
12
faster on monadpostulate, not sure why.
14
20110823: Got rid of projection arguments. Cut the monad examples in half, but
15
no effect on prim which is kind of odd since ... oh we're using a
16
datatype in prim. Changing that to a record and rerunning.
18
20110823: (08:00) Sigma record in prim and added all projections instead of
21
20110825: Allow instantiation of blocked terms, and short-cut instantiation of
24
20110830: New computer.
26
20110830: (18:00) Added patternmatch test case. Needs abnormal amounts of
29
20110901: Removed a clause from the patternmatch case. The reason it requires
30
so much memory is coverage checking. It's expected with the current
31
algorithm. It could potentially be improved by separating coverage
32
checking from unreachability checking, but this isn't really a
33
problem in practise. GHC checks both completeness and overlap
34
instantly, so it is possible.
36
20110901: (12:30) Set.mapMonotonic instead of Set.map when lowering sets of
37
free variables under a binder.
39
20110901: (13:30) New projection benchmarks (record, data and nested) to test
40
eliminator detection for projection-like functions.
42
20110902: Implemented projection detection.
44
20110906: New state monad implementation (IORef s -> m a)
46
20110907: (01:00) Pushing types into constructor applications.
48
(03:00) Treating (\x -> x) as (\(x : _) -> x). Note increase in
51
(03:26) Pushing types into lambdas, helps a little, but not as much
52
as we would like: For cwf we had 2794 metas before the (\x -> x)
53
change, 3242 after, and 3038 after this fix.
55
(04:48) Taking better care of types in lambdas. Metas for cwf now
56
down to 2834, so almost what we had before.
58
(05:33) Removed all 'abstract's from the cwf benchmark. Very little
59
difference! 3.1s -> 3.7s and 43MB -> 61MB.
61
20110908: Fixed issues 311, 450 and 451.
63
20110909: Minor improvement of FreeVars.singleton and added
64
Data.List.Any.Properties as a benchmark.
66
20110910: Can't remember.
68
20110915: (07.38) New constraint handling machinery.
69
(08.47) No more quadratic nubbing in localNames
70
(09.14) Don't reduce sorts when reducing types
71
(13.11) Got rid of most MonadTCMs
73
20110919: Positivity checker needs to look at pattern matching.
75
20110922: Just minor stuff.
77
20110924: (09.49) New mutual syntax.
78
(10.04) Avoid generating sort metas when checking isType_ of a Fun or a Pi
79
( ) Same for isType_ of Set or Set a
81
20120406: Qualified mixfix operators
84
20120705: Sharing is working but under-utilized
85
20121005: (18.37) With sharing
86
(20.31) Without sharing
