49 Improvemens ot accuracy of split zone detection. tbourke 1763d 15h 05m /trunk/src/
48 Bump the version number. tbourke 1834d 16h 21m /trunk/src/
47 Implement new technique for handling channel arrays. tbourke 1834d 16h 21m /trunk/src/
46 Rename the xml directory to uppaalxml. tbourke 1835d 10h 37m /trunk/src/
45 Rename the parse directory to uppaal. tbourke 1835d 10h 40m /trunk/src/
44 Just after implementing the improved channel array technique.
The code compiles but has not been tested.		 tbourke 1835d 10h 45m /trunk/src/
43 Remove the pos field from expressions. tbourke 1836d 15h 24m /trunk/src/
42 Make declaration into a functor. tbourke 1836d 16h 12m /trunk/src/
41 No need for expression to be a functor. tbourke 1836d 16h 14m /trunk/src/
36 Unexpanded types in selection bindings were causing exceptions. tbourke 1868d 15h 35m /trunk/src/
35 Fix a nasty bug when combining location invariant expressions with
transition guards: the selection bindings of the transition guard were not
being considered properly leading to improper variable captures by foralls
in the location invariant expression.		 tbourke 1874d 19h 12m /trunk/src/
34 Fix a nasty bug in ClockExprTrans.negate: it was turning invariant forall
bindings into transition exists bindings. But, the invariant is not negated,
so the bindings shouldn't change.

Also tidied up the debugging output. It is more hierarchical now.		 tbourke 1875d 11h 19m /trunk/src/
33 Improve debugging indentation output. tbourke 1875d 16h 59m /trunk/src/
32 Added warnings for urgent channels leaving locations with invariants
containing clocks as they may lead to `Clock guards are not allowed on
urgent edges' warnings.		 tbourke 1875d 18h 31m /trunk/src/
31 Add a negateInvariant function to TransitionFlipper, to avoid negated
invariants that split clock zones.		 tbourke 1875d 22h 52m /trunk/src/
30 Add the mapBoth value to Environment, and update EnvironmentPP, so that
typedefs are sorted along with variable declarations.

Otherwise input like this:
const int N = 4;
typedef int[0, N-1] id_t;

ends up as output like this:
typedef int[0, N-1] id_t;
const int N = 4;		 tbourke 1876d 11h 35m /trunk/src/
29 Implement ATrans.reduceSelectIds so that Urpal is a bit more flexible about
selection bindings used around subexpressions without clocks in guards and
not in channel array subscripts. (see 20080329)		 tbourke 1876d 17h 38m /trunk/src/
28 Further improve the error output of the Graphviz modules.
Add more debugging output to Graphviz plain output parser.
Handle escaped newlines inserted by Graphviz on long lines,
rather than die with a PIPE signal.		 tbourke 1877d 22h 45m /trunk/src/
27 Bug fix: invertActionAndAddInvariant failed to add selection bindings to the
environment passed to TransitionFlipper.andExpr, resulting in
NonClockTerm exceptions for valid terms.		 tbourke 1878d 16h 18m /trunk/src/
26 The ClockExpression.fromExpr function was faulty because Expression.filter
did not properly respect forall and exists bindings. This has been fixed by
shifting filter into the Environment module.		 tbourke 1878d 18h 05m /trunk/src/
25 Improve the error message when an mcs51 file cannot be opened. tbourke 1957d 20h 45m /trunk/src/
24 Minor tuning to placement of labels.
Add items to TODO list.		 tbourke 1957d 20h 58m /trunk/src/
23 Minor changes to build files. tbourke 1967d 19h 06m /trunk/src/
22 Add path maps to allow for compilation under Unix and Windows. tbourke 1993d 09h 14m /trunk/src/
21 Hacks to work under Cygwin.
Fix for selection ids in multiple dimensions of channel array.		 tbourke 1993d 09h 30m /trunk/src/
20 Update compilation under MLton.
Add multiply clocks feature.		 tbourke 1994d 16h 31m /trunk/src/
19 Implement the new canswap version that checks for exist/forall conflicts.
Fixed a bug that prevented the layout of transitions for urgent channels.		 tbourke 2000d 21h 47m /trunk/src/
18 Create layout submodule and copy scattered functions into it.
Fix up layout of mcs51 models.		 tbourke 2007d 18h 38m /trunk/src/
17 Add MCS51 feature. tbourke 2018d 11h 43m /trunk/src/
16 Add .ml files for building with Poly/ML. tbourke 2021d 23h 01m /trunk/src/
