--- Comment #4 from Gary Funck <gary at intrepid dot com> --- (In reply to Jay from comment #2) > 1 please be sure that dividing the most negative number by -1 "works". > Perhaps just don't optimize anything with negstive numbers. - Checking for negative numbers at compile-time can only be done on integer constant values. - Whether dividing the max negative number by -1 just "works" depends upon the definition and implementation of FLOOR_DIV_EXPR. - For UPC's use of FLOOR_DIV_EXPR, it isn't possible to construct that scenario.
