Summary0000260: is_finite predicate: type double expected instead of real in .jc file
DescriptionLaunching: frama-c -jessie foo.c
with foo.c containing:

double f(double a , double b )
{
  double t ;
  t = 0.0;
  //@ assert \is_finite((double)(a-b));
  t = a - b;
  return (t);
}

yields:

File "foo.jc", line 36, characters 56-71: typing error: type double expected instead of real
[jessie] user error: Jessie subprocess failed: jessie -why-opt -split-user-conj -v -locs foo.cloc foo.jc

":> real" in foo.jc should be removed when used within "is_finite_double" predicate, not?

Dillon

it is solved now by adding the following warning when the used mode is "real":

"\is_finite always true in mode JessieFloatModel(real)"

We have an analogue warning for the "strict" mode and for "\is_infinite,\is_NaN,\is_plus_infinity,\is_minus_infinity".

Best regards.
