Elena Demikhovsky e46025656d Fold fcmp in cases where value is provably non-negative. By Arch Robison. ... This patch folds fcmp in some cases of interest in Julia. The patch adds a function CannotBeOrderedLessThanZero that returns true if a value is provably not less than zero. I.e. the function returns true if the value is provably -0, +0, positive, or a NaN. The patch extends InstructionSimplify.cpp to fold instances of fcmp where: - the predicate is olt or uge - the first operand is provably not less than zero - the second operand is zero The motivation for handling these cases optimizing away domain checks for sqrt in Julia for common idioms such as sqrt(x*x+y*y).. http://reviews.llvm.org/D6972 llvm-svn: 227298		2015-01-28 08:03:58 +00:00
