INCOMPATIBILITY.  Adaptions may be required in the following cases:
haftmann
parents: 25177
diff changeset
  2047
haftmann
parents: 25177
diff changeset
  2048
a) User-defined constants using any of the names "plus", "minus",
haftmann
parents: 25177
diff changeset
  2049
"times", "less" or "less_eq". The standard syntax translations for
haftmann
parents: 25177
diff changeset
  2050
"+", "-" and "*" may go wrong.  INCOMPATIBILITY: use more specific
haftmann
parents: 25177
diff changeset
  2051
names.
haftmann
parents: 25177
diff changeset
  2052
haftmann
parents: 25177
diff changeset
  2053
b) Variables named "plus", "minus", "times", "less", "less_eq"
haftmann
parents: 25177
diff changeset
  2054
INCOMPATIBILITY: use more specific names.
haftmann
parents: 25177
diff changeset
  2055
haftmann

diff changeset
  2056
c) Permutative equations (e.g. "a + b = b + a")
haftmann
parents: 25177
diff changeset
  2057
Since the change of names also changes the order of terms, permutative
haftmann
parents: 25177
diff changeset
  2058
rewrite rules may get applied in a different order. Experience shows
haftmann
parents: 25177
diff changeset
  2059
that this is rarely the case (only two adaptions in the whole Isabelle
haftmann
parents: 25177

distribution).  INCOMPATIBILITY: rewrite proofs
haftmann
parents: 25177
diff changeset
  2061
haftmann
parents: 25177
diff changeset
  2062
d) ML code directly refering to constant names
haftmann
parents: 25177
diff changeset
  2063
This in general only affects hand-written proof tactics, simprocs and
haftmann
parents: 25177

so on.  INCOMPATIBILITY: grep your sourcecode and replace names.
haftmann

sgn are given as equational assumptions in the classes sgn_if and

* The transitivity reasoner for partial and linear orders is set up

for classes "order" and "linorder".  Instances of the reasoner are available
