* Paul Schlie:
(With an exception being FP optimization, as FP is itself based only on the approximate not absolute representation of values.)
Floating-point arithmetic is not simply some inaccurate representation of real arithmetic. It can be used this way by the programmer, but in fact fpt operations have very well defined semantics, and compiler writers have to be very careful not to intefere with these semantics beyond the level permitted by the language. Certainly the above quoted attitude would be pretty deadly if held by a compiler optimizer writer!
