Is it possible to intercept primitive operations (+,-,% etc.) like this one, with LD_PRELOAD?
int64_t endWhenNsec = startWhenNsec + gTimeLimitSec;
If not, any way to achieve something similar?

1no, because usually, integer arithmetic operations aren't implemented as functions but as primitive instructions known to the CPU. – The Paramagnetic Croissant Oct 07 '14 at 13:45

No. Primitive operators are compiled directly to machine code. There is no library involved, so preloading libraries cannot alter their behavior. What a mess if it could!
