Branch 'master' now includes:
cc2d2e1... Midstream check-in on (i) Replaced a lot of clunky and
fragile EvVar handling code with a more uniform ``flavor transformer''
API in the canonicalizer and the interaction solver. Now EvVars are just
fields inside the CtFlavors. (ii) Significantly simplified our
caching story This patch does not validate yet and more refactoring is on the
way.
b4b7647... Merge branch 'master' of http://darcs.haskell.org/ghc into
ghc-new-flavor
c6411c3... Slightly more informal message when EvCast fails.
3be60fa... Bugfixes: (i) wrong evidence generetation when using cached
solved family equation (ii) evidence loops because of caching fixed
4e0f1a0... Small bugfix (for indexed_types/should_compile/T2291.hs).
Because our inert sets do not tolerate more than a single constraint per family
head we have to allow family interactions /with the inerts/ (not with
top-level) when the context says simplEqsOnly.
1cc92e9... defaultKind the kind of one of the types when you create a
higher-dimensional equality proof, pretty much as we do for mkTcEqPred. Ugly
and delicate but we have to rething the subkinding story. For now I am doing
the same thing as mkTcEqPred.
81faaee... Merge branch 'master' of http://darcs.haskell.org/ghc into
ghc-new-flavor
bf334d2... Add handling of LitTy. Still a TODO to deal properly with the
forall case in there.
e74fbf0... Started investigating how performance is affected and how
intensively our caches are used.
f30f90b... More informative commentary as to why we allow family
interactions with inerts when simplEqsOnly is on.
3f42011... Changing the orientation of a generated equality
f84ea58... Deleting A LOT of commented out code!
d86e6c0... A little tracing.
6785820... Mostly commentary to follow up after discussions with SPJ on
several open tickets.
b3f6a8b... Merge branch 'master' of http://darcs.haskell.org/ghc into
ghc-new-flavor
8580b97... Deleting more old commented code.
5802ebd... Dropping the idempotence restriction on the inert substitution,
for efficiency. More documentation to follow.
f9da524... Commentary, following the relaxation of idempotence of the
inert substitution.
d29e277... Bugfix in emitKindConstraint (must not cache orig constraint as
Solved!); added short note to document an example.
8737d47... When rewriting a flavor with rewriteCtFlavor, in the case of
reflexivity, avoid setting the flavor PredType to be the new PredType if the
types exactly match, so that in case of failure we report errors that do not
have expanded type synonyms.
2183c87... More informative tracing for ddump-cs-trace
e3e740d... Wibble: using original type for the dictionary if it has not
changed (to preserve synonyms)
d3020a7... Adding a forgotten pre-canonicalication cache-lookup stage.
0dd6cc5... Merge branch 'master' of http://darcs.haskell.org/ghc into
ghc-new-flavor
022c1d2... Merge branch 'master' of http://darcs.haskell.org/ghc into
ghc-new-flavor
1a4ae30... Merge branch 'master' of http://darcs.haskell.org/ghc into
ghc-new-flavor
