I did not get around to test your proposed patch yet, but it seems like the new
"logical not" operation always compares only the low 32 bit against zero, even
if there is a 64 bit operand. If my analysis is correct, the long long test
program should fail if you replace "decision = 1;" by "decision =
0x100000000LL;"
