the man page:
-fwrapv
This option instructs the compiler to assume that signed arithmetic
overflow of
addition, subtraction and multiplication wraps around using
twos-complement
representation. This flag enables some optimizations and disables
others. This option
is enabled by default for the Java front end, as required by the
Java language
specification.
-fwrapv is also mandated by go specification
