This option allows GCC to violate some ANSI or IEEE rules and/or specifications
in the interest of optimizing code for speed. For example, it allows the
compiler to assume arguments to the `sqrt' function are non-negative numbers and
that no floating-point values are NaNs.
This option should never be turned on by any `-O' option since it can result in
incorrect output for programs which depend on an exact implementation of IEEE or
ANSI rules/specifications for math functions.
