Summary

0000745: Very big integer constants

Description

Integer constants are de facto limited to int64 by Cil. Should use Big_int to accept any constant.

Steps To Reproduce

void main(void) {
/*@ assert 0xfffffffffffffffff == 0xfffffffffffffffff; */
}

$ frama-c a.c
a.c:1:[kernel] failure: Cannot represent on 64 bits the integer 0xfffffffffffffffff

Notes
(0002051) yakobowski (manager) 2011-07-25 22:29	I'm a bit lost concerning this issue. We have introduced support for long integers in the AST, but this bug is still not closed. Integers within ACSL terms require an ikind, which limit them to C representable integers. Do we need another constructor for overly long integers, or am I missing something?

(0002054) monate (reporter) 2011-07-26 11:30	You're not missing anything.
