Can I confirm that the following C code gives undefined result for b:
unsigned a = 0;
int b = a - 1;
(§6.3.1.3/3): “…either the result is implementation-defined or an implementation-defined signal is raised.”
On typical twos-complement hardware, I’d expect the result to be -1.
Note that the result is implementation defined, not undefined.
