please find attached a patch for PR 59604.
The patch makes sure that, if -fno-range-check is specified,
using int on an overflowing boz constant yields the same
result for compile-time simplification and run-time
execution.
OK for trunk?
Looks good to me. At a glance, it looks as if it also fixes the original
bug 58003 - or is something still missing?
